Computer Numerical Control (CNC) machines have revolutionized the manufacturing industry, improving product quality, operational efficiency, and reliability. This technology has become immensely popular, and it is expected that by 2028, the global CNC machine market size will reach $140.78 billion, with a compound annual growth rate of 7.1%. Like any other technology, these manufacturing powerhouses can encounter malfunctions and other issues. Without proper knowledge, these relatively minor issues can have far-reaching impacts.
CNC machining is a form of automated manufacturing that uses precise tools (rotating tools on a spindle (CNC mills) or fixed tools against rotating raw materials (CNC lathes)) to create complex parts. The spindle's role is to provide the necessary rotational motion for accurate material removal. Additionally, CNC machining is an omnipresent force within the manufacturing industry, particularly crucial in sectors that rely on metal and plastic production.
These machines utilize carefully crafted algorithms designed by engineers to send precise instructions to the machine tools, orchestrating their movements and managing auxiliary processes. This crucial process empowers precision cnc machining and the skilled machinists who oversee it, allowing them to deliver unparalleled versatility, efficiency, and precision. This capability extends from the manufacture of tiny electronic components to the production of vast aircraft and aerospace parts.
Common problems with CNC machines can have serious consequences. Errors might seem trivial, but if not detected in time, they can cause significant damage to tools and machines. These issues can reduce the lifespan of the machine and affect productivity, leading to replacement costs or significant downtime. Over time, they can lead to complete failures.
Identifying and addressing common machine issues can extend the lifespan of CNC machines. Predictive and proactive maintenance can also reduce downtime, keeping our machining tools in optimal working condition, thereby improving overall efficiency. The most common CNC machine problems include the following seven aspects:
1. Code Errors
Computer-driven machines rely on complex code, and programming is one of the most common mistakes machine operators encounter. These errors can be caused by incorrect variables inputted into the program, wrong settings, or a lack of understanding of different G and M computer codes.
These issues can be difficult to detect, especially if employees lack experience. Many people will immediately look at the machine and overlook that the problem might originate from the computer. Wasted time, materials, and machine damage can result in high costs and slow operations.
2. Lack of Maintenance
CNC machines, such as 5 axis cnc machine, consist of many moving mechanical systems that must work within extremely tight tolerance requirements to ensure product quality. The slightest error, wear, or debris can severely impact machine performance, causing jams or permanent damage. Over time, dirt and debris will accumulate, and small errors will become more significant, eventually leading to machine failure.
Material movement, overheating, and noise during the cutting process are common signs of issues with CNC machines. The most common signs of overdue maintenance include slight machine errors, such as surfaces that do not meet standards or barely meet standards.
3. Vibration or Humming
Vibration during operation can shorten the tool's lifespan, affecting its durability and long-term functionality. Chatter and vibration can impact the machine's work efficiency and cost-effectiveness. If the operator discovers any unusual noise or vibration, they should identify the source of the vibration and take necessary measures to resolve the issue.
However, machine vibration often exists long before it is noticed by the human ear. Modern maintenance practices include regular monitoring of vibration and ultrasonic frequencies to detect minor performance defects.
4. Chuck Clamping Issues
Failure to clamp the workpiece securely on the machine is another common mistake in CNC machining. Incorrect clamping can lead to issues such as deviation, chatter, or deformation, causing damage to the machine or workpiece. If the chuck cannot hold the workpiece securely, a replacement might be necessary. This problem can be more severe than damaging workpieces or tools. Improper clamping of machine parts can cause accidents and injure operators, affecting the entire operation's safety.
5. Incompatible Power Supply
If an operator finds performance issues with the machine, it could be due to a problem with the power supply. The power supply must always provide the correct voltage to the input end. The output end must also work correctly to ensure the machine gets enough power. Machines with insufficient power need to work longer to achieve the same effect, leading to tool failure or workpiece damage. Excessive power can damage the machine, even causing complete failure.
6. Improper Tools or Settings
Incorrect cutting tools can affect the quality of material processing. Pay attention to tool marks on the edges and corners of materials, rough edges, or burn marks. Repeated use of improper tools or settings can cause severe tool wear. Dull tools and incorrect speed ratios can also result in rough material surfaces.
7. Overheating
Overheating is a common issue in large-volume and long-term machining. Spindle overheating is usually caused by an unclean machine and inadequate airflow. Environmental temperature can typically cause overheating, affecting work quality, tools, and the machine. A typical CNC machine should maintain a stable temperature range to prevent adverse effects.
While it can sometimes be challenging to avoid issues when operating complex machinery, supervisors can take specific measures to minimize unnecessary damage and malfunctions. Preventative methods can save time and money, avoiding unnecessary downtime, repairs, and replacements. Taking the following steps can minimize the impact of common errors and maintain the machine's lifespan:
Prioritize Operator Training: Human errors are common in production, whether it's choosing the wrong tool or data entry mistakes. Ensure operators receive extensive training and user manuals, and let experienced operators guide them until they are familiar with the relevant settings and protocols.
Develop a Preventative Maintenance Plan: CNC machines, for example, steel cnc machine, require regular cleaning and maintenance. Develop a detailed maintenance plan and ensure the team records any repairs to keep a comprehensive record of each machine's issues. Operators should routinely inspect the machines, ensure coolant levels are sufficient, and identify signs of wear.
Conduct Vibration Analysis: Vibration analysis allows machine maintenance experts to monitor machine vibration data and detect potential issues. It can detect bearing faults, shaft bending, misalignment, loose components, and more. If an operator is concerned about vibration issues, consult a professional to help identify the root cause.
Monitor the Environment: Environmental factors are an essential part of efficient CNC machine operation. Monitor temperature, humidity, noise, and power fluctuations to ensure the machine has an efficient operating environment.
Calibrate Machines: Regular calibration maintains the machine's accuracy and reliability. Follow the manufacturer's guidelines and have experts regularly inspect the machine, addressing small issues before they become significant problems.
Machine issues and operator errors can lead to significant operational losses. Partnering with experienced, reliable machine experts can minimize these problems through comprehensive after-sales service and trustworthy guidance on proper setup, programming, and maintenance. These professionals can also advise on whether to repair or replace equipment, thereby extending uptime and machine lifespan.
EDM has two main types: traditional or plunge EDM, and wire or wire-cut EDM. As mentioned above, traditional EDM uses a tool to disperse an electric current. The tool (cathode) moves along a metal piece (anode) and melts or vaporizes the metal through the current response. Due to the dielectric fluid, usually a hydrocarbon oil, both the cathode and the workpiece are immersed in it, which flushes away the tiny debris generated during the process. Wire EDM (or WCEDM) releases charged current through a thin wire under tension, acting as the cathode and guiding along the desired cutting path or cut. In this case, the dielectric fluid (usually deionized water) flushes through the cut during cutting, once again helping to remove particles and control sparks. The thin metal wire allows for precise cuts with narrow kerfs (usually about 0.015 inches, which offers fine cuts) and tolerances of about +/- 0.0001 inches. This high precision allows for complex three-dimensional cuts and produces highly precise punches, dies, and stripper plates.
As a trusted and professional custom precision machining factory in China, our Wire EDM equipment is operated by computer numerical control (CNC) devices that can control the wire on three-dimensional axes to provide greater flexibility. Simple cuts are accomplished by changing the tool's x-y coordinates, while more complex cuts are achieved by adding motion axes to the wire guide rails. Four-axis and five-axis wire EDM machines and services are available. Traditional EDM cannot always produce tight angles or very complex patterns, but the precision of wire EDM machines allows for complex patterns and cuts. Additionally, wire EDM can cut metal materials as thin as 0.004 inches and thicker than 16 inches. In routine cases, there may be thicker sections. At certain material thicknesses, wire EDM will vaporize the metal, removing potential debris. The wire in a WCEDM device sparks on all sides, meaning the kerf must be thicker than the wire itself. In other words, since the wire is surrounded by an electric current ring, the smallest and most precise cutting path may be the added diameter of the ring and the wire; technicians can easily interpret this added size. Manufacturers continue to produce thinner wires for smaller kerfs and higher precision.
Due to its versatility, manufacturers can use wire EDM machines for a wide range of applications. Because this process can cut very small workpieces, it is often ideal for producing small, high-precision parts that are usually too delicate for other machining schemes. Moreover, this process is cost-effective for producing small-batch projects, and it can also prove beneficial for prototype manufacturing even if actual projects are conducted differently. It is important to remember that the wire continuously moves during machining and cannot be reused. Therefore, copper, brass, or other metal wires can be miles long, increasing the process cost. Furthermore, although the process does not use any force and therefore does not produce burrs, making it suitable for fragile items, the possibility of thermal stress definitely exists. Most machining operations involving wire EDM start with roughing, which has a fairly fast feed rate and high dielectric constant. Continuous skim passes use smaller kerfs, reducing dielectric fluid flow to achieve a finished surface to tolerance. Reduced dielectric flow prevents the wire from deforming during these skim passes. Cuts that do not start along the part's edge (such as holes) require pre-drilling to allow the wire to pass through. Many wire EDM machines are equipped with electrodes for small hole drilling, allowing starter holes to be machined in hardened steel without using conventional drills. Small hole drilling usually uses an EDM electrode mounted on a rotating spindle, with the dielectric fluid pumped through the electrode to flush the hole. The process of using a separate EDM drill to create small holes in hardened materials is sometimes called splicing.
Compared to traditional EDM machining, the main advantage of wire edm machining services is that the continuous power supply minimizes wear on fixed electrodes. Wire EDM machines consume a significant amount of wire, which correspondingly increases the cost. Many wire EDM machines are self-threading, so even if the wire breaks, the entire machining process can continue almost uninterrupted.
Another major advantage is the ability to cut parts after heat treatment, eliminating the possibility of deformation caused by post-processing after machining. Additionally, because the wire EDM machining method does not apply any machining pressure to the workpiece, it is easy to machine small parts. Compared to traditional machining methods, the requirement for fixtures is minimal. Very fine surfaces can be machined.
In recent years, CNC machining has rapidly dominated the manufacturing industry due to its high precision and repeatability. With the multitude of CNC technologies available today, understanding the basics of CNC machining will help you distinguish their features. One of the innovative technologies is CNC turning.
It involves removing material from a rotating rigid workpiece using non-rotating cutting tools in a turning center or lathe. The CNC turning process can produce parts of different shapes and sizes depending on the type of turning operations. Although this concept seems quite simple, high-quality CNC turning can be very complex.
CNC turning is a high-precision, high-efficiency subtractive machining process that operates similarly to a lathe. It involves placing the cutting tool on the turning workpiece to remove material and achieve the desired shape. While the raw material rotates at high speed, the turning center or lathe remains fixed. When the workpiece rotates and moves along the dual CNC lathe axes, the single-point cutting tool helps shape the material. Computer programs help control the turning center or lathe, ensuring the production of extremely precise parts. People often confuse CNC turning and milling, but they are different processes. The precision cnc milling and most other subtractive CNC processes generally fix the workpiece on the machine bed, while using rotating tools to cut the material. In contrast, CNC turning uses the opposite process, where the workpiece rotates while the cutting tool remains stationary.
Due to its mode of operation, CNC turning is commonly used to produce cylindrical or oval-shaped parts. However, it can also create multiple axially symmetric shapes. These shapes include cones, disks, or a combination of shapes. Some turning centers even allow polygonal turning operations with special rotating tools, enabling the creation of hexagonal or square components.
CNC turning offers several benefits, including:
1. Accuracy
CNC lathes can perform precise measurements using CAD or CAM files and eliminate human errors. Whether for prototype production or completing an entire production cycle, experts can use advanced machinery to achieve incredibly high precision. Since the machines used are programmed, each cut is precise. In other words, the last piece in a production run is identical to the first piece.
2. Flexibility
Turning centers come in various sizes to meet the flexibility of your application. Adjustments are fairly easy because the machine's tasks are pre-programmed. Operators can complete your components by making necessary programming adjustments to your CAM program, or even build something entirely different. Hence, if you need many unique parts, you can rely on the same cnc precision machining service company.
3. Ensured Safety
Manufacturing companies adhere to strict safety regulations to ensure complete safety. As the lathe is automated, it requires less labor since operators are there only to monitor the machines. Likewise, the lathe body comes with fully enclosed or semi-enclosed protective devices to prevent scattered particles during processing, reducing harm to workers.
4. Faster Results
When performing programmed tasks on a CNC lathe or turning center, the chances of error are lower. Thus, the machine can complete production faster without sacrificing the quality of the final output. Eventually, you can receive the necessary components faster than with other options.
The CNC turning process can be quite complex. However, we will provide you with a simplified step-by-step breakdown from design to manufacturing. The general steps for cnc turning service are:
1. Convert CAD Design File to CNC Program
The first step involves preparing the CAD file to be translated into the CNC lathe language. This does not involve advanced programming. You must already have some 2D drawings of the design. In this case, you need to electronically capture these designs using software like AutoCAD or SolidWorks. Once you have the electronic design in CAD file format, you can convert it into a CAM program. You can also export the drawing in CAM format using the same software tools mentioned above. Then, manufacturing engineers can use the software to test the manufacturability of the component.
2. Prepare the CNC Lathe
The next step is machine setup. Although most of the process is automated, an operator is still required. To effectively prepare the CNC lathe, follow these steps:
Ensure the power is off. The CNC machining process can become very dangerous. Therefore, you should be extra cautious and check the power switch.
Secure the part to the chuck. The chuck is responsible for holding the part in place during the turning process. Incorrectly loading it can be dangerous and may result in incorrect component dimensions.
Load the tool turret. Turning operations involve multiple tools, so you must ensure to select the correct tool for the specific finishing. The turret helps hold as many tools as possible at once, allowing for seamless operations.
Ensure correct alignment. You must set the tool and workpiece correctly to ensure the results meet the requirements.
Upload the CNC program. The last step before starting the operation is to upload the CNC code into the machine.
At this stage, you need to keep two variables in mind. The first is the turning speed (the speed at which the workpiece rotates). The second variable is the feed rate (the speed at which the cutting tool moves along the rotating workpiece). Professional machinists must determine these values because incorrect estimations can affect the final result. Additionally, incorrect estimations for some materials may result in uneven surfaces or irreparable damage to the workpiece. That said, you can stick to low turning speeds and high feed rates for "roughing" the shape. On the other hand, high turning speeds coupled with lower feed rates are ideal for smooth surfaces and parts with precise tolerance requirements.
3. Manufacture CNC Turning Parts
The final step is to manufacture the parts you want. You can choose different turning operations depending on the results you wish to achieve. Furthermore, the complexity of the part will determine how many cycles you will have. Cycle time calculation will help you understand the total time spent on the component, which is crucial for cost estimation. Typically, turning cycle times include:
(1) Loading time. Although this is part of the setup, a cycle may require a different method of loading the workpiece onto the machine.
(2) Cutting time. This is the time required to cut the workpiece. Feed rate and cut depth are factors that influence cutting time.
(3) Idle time. Any operation that does not involve cutting is an idle operation. For example, changing the setup of the turning center, moving tools, etc.
The result of the manufacturing process will depend on the raw material used. Parts made from plastic will differ in functionality and surface roughness compared to those made from metal.

CNC machining has revolutionized manufacturing by providing high precision and accuracy in the production of parts and components. However, even the most precisely manufactured parts are susceptible to corrosion, wear, and other environmental factors. This is where surface treatments come in—they help protect CNC machined parts from damage and extend their service life. In this article, we will introduce some of the most commonly used surface treatment solutions for CNC machined parts.
Anodizing is a process that uses an electrolytic solution to form a protective oxide layer on the surface of a part. This layer provides excellent corrosion resistance and enhanced wear resistance. Anodizing can be done in various colors, making it an attractive choice for decorative applications.
As one of precision manufacturing services, Electroplating involves depositing a thin layer of metal on the surface of a part. Electroplating can be done with various metals, including chrome, nickel, copper, and gold. This surface treatment provides excellent corrosion resistance, as well as improved conductivity and aesthetics. Powder coating involves applying a dry powder to the surface of a part and then heating it to form a hard and durable coating. Powder coating offers excellent corrosion resistance, weather resistance, and wear resistance. It can also be done in various colors, making it an attractive choice for decorative applications. PVD coating is a product of Physical Vapor Deposition technology. This technique involves vaporizing the surface of a material source (solid or liquid) into gaseous atoms or molecules, or partially ionized into ions, under vacuum conditions, and then depositing thin films with specific functions on the substrate surface.
Chemical conversion coatings involve forming a thin chemically bonded layer on the surface of a part. This layer provides excellent corrosion resistance and improved adhesion for subsequent painting or other surface treatments. Common types of chemical conversion coatings include chromate and phosphate coatings.
Heat treatment involves subjecting parts to high temperatures to alter their properties. This can include hardening, tempering, and annealing. Heat treatment can improve the strength, durability, and wear resistance of parts.
Laser marking involves using a laser to create permanent high-contrast marks on the surface of a part. Laser marking can be used for both functional and decorative purposes and can be performed on various materials.
In conclusion, there are various surface treatments available for CNC machined parts to enhance their durability, corrosion resistance, and aesthetics. Anodizing, electroplating, powder coating, chemical conversion coatings, heat treatment, and laser marking are common surface treatments that can help extend the life of CNC machined parts.
