CNC milling machines are a cornerstone of modern manufacturing, shaping and refining metal, plastic, and other materials with unmatched precision. But what exactly is a CNC milling machine, and how does it work? How does it differ from other CNC machines like lathes? More importantly, what are the key components that make it function so effectively? At its core, CNC milling is a subtractive machining process that uses rotating cutting tools to gradually remove material from a workpiece. These machines are widely used across industries such as aerospace, automotive, medical, and precision engineering. With advancements in technology, CNC mills now feature multi-axis capabilities, automatic tool changers, and advanced cooling systems—enhancing efficiency and accuracy like never before. Understanding the parts and components of a CNC milling machine is crucial for anyone involved in manufacturing. In this guide, I’ll break down the essential elements that keep these machines running smoothly, from the spindle and worktable to the control system and cutting tools. Whether you're new to CNC machining or looking to deepen your expertise, this article will give you a comprehensive overview of CNC milling machine components and their functions. How Does a CNC Machine Work?  A CNC (Computer Numerical Control) machine operates by following pre-programmed instructions to precisely cut, shape, or engrave materials such as metal, wood, plastic, and composites. The process begins with a CAD (Computer-Aided Design) file, where engineers or designers create a detailed 2D or 3D model of the desired part. This digital blueprint is then converted into G-code using CAM (Computer-Aided Manufacturing) software, which translates the design into specific commands that control the CNC machine’s movements. Once the program is loaded into the machine’s controller, the operator secures the raw material onto the machine’s worktable and selects the appropriate cutting tool. When the CNC machine begins operating, it moves along multiple axes (X, Y, and Z for basic machines, with additional A, B, and C axes for more complex ones) to follow the programmed path with extreme precision. High-speed motors, ball screws, and advanced sensors ensure accurate positioning and smooth operations. Depending on the type of CNC machine, whether it’s a milling machine, lathe, router, plasma cutter, laser cutter, or even a 3D printer; the tool either removes material (subtractive manufacturing) or adds material (additive manufacturing) to shape the final product. Throughout the process, automated monitoring systems track the machining progress to ensure consistency and quality. Once machining is complete, the part may require additional finishing processes such as sanding, deburring, or polishing before undergoing a final quality inspection, often using coordinate measuring machines (CMMs) or laser scanners to verify accuracy. CNC machines revolutionized modern manufacturing by providing high precision, repeatability, and efficiency, making them essential in industries such as aerospace, automotive, medical, and electronics manufacturing.   Major Parts of a CNC Milling Machine A CNC milling machine consists of several components that work together to perform machining operations. Each part plays a crucial role in ensuring smooth and precise milling. Here is a breakdown of the primary parts of a CNC machine: CNC Controller The CNC controller is the brain of the machine. It interprets G-codes and converts them into precise movements by sending signals to stepper or servo motors. This eliminates the need for manual operation, making the machine more efficient and reducing human error. Column and Base The column and base form the foundation of a CNC milling machine. Typically made from cast iron, they provide rigidity and stability, reducing vibrations during cutting. The base supports the entire machine, while the column houses essential components like the coolant and oil systems. Knee The knee is an adjustable vertical part connected to the column. It facilitates vertical movement of the worktable, allowing the milling tool to reach different levels of the workpiece. Saddle The saddle sits on top of the knee and allows movement along the X and Y axes, positioning the workpiece correctly for machining. Feed Mechanism CNC machines use an electromechanical feed mechanism that controls the three-dimensional movement of the milling machine. This is powered by motors that execute movements as per the CNC program. Work Table The work table is the flat surface where the workpiece is placed. It includes T-slots that help secure the material using clamps or vices. Some advanced machines offer hybrid worktables that support both CNC milling and plasma cutting. Spindle The spindle is a rotating component that holds and drives the milling tool. It is typically made of high-carbon chromium steel and can operate at various speeds, depending on the material and operation. Milling Chuck The milling chuck holds the cutting tool firmly in place. It consists of jaws that can be tightened or loosened to accommodate different tools. Ram (For Vertical CNC Machines) In vertical CNC machines, the ram is a movable arm that supports the milling head. It allows forward and backward movement for greater flexibility in machining. Overhanging Arm (For Horizontal CNC Machines) In horizontal CNC milling machines, an overhanging arm replaces the ram. It supports the arbor, which holds the milling cutter in place. Arbor Support (For Horizontal CNC Machines) The arbor support holds the arbor and cutting tool, ensuring stability and vibration reduction during cutting operations.   Common Accessories Used With CNC Milling Machines Accessories improve the performance, safety, and efficiency of CNC milling machines. Some common accessories include: Coolant System A coolant system prevents overheating by spraying coolant on the cutting area. This reduces friction, prevents tool wear, and improves surface finish. Coolants can be water-based (for heat reduction) or oil-based (for lubrication). Powered Drawbar A powered drawbar allows automatic tightening or loosening of the tool, reducing the time required for manual tool changes. Safety Enclosure A safety enclosure is a protective barrier that prevents chips, dust, and coolant splashes from flying outside the machine. This enhances operator safety. 4th Axis or Rotary Kit A rotary kit enables 4-axis machining, allowing for the milling of cylindrical or curved surfaces. This is essential for engraving and complex part manufacturing. Automatic Tool Changer (ATC) An automatic tool changer (ATC) switches tools automatically based on the CNC program, making it ideal for complex machining tasks that require multiple tools. Chip Tray A chip tray collects metal or material chips, preventing buildup and making cleanup easier. Machine Guards Machine guards protect moving parts to prevent accidents, adhering to ISO 13849 safety regulations. Most Important Tools Used with CNC Milling Machines CNC milling machines use different cutting tools depending on the operation and material. These tools are typically made of high-speed steel (HSS) or carbide for durability. End Mills End mills are the most common milling tools. They come in different shapes and sizes for specific operations: ● Flat End Mills: Used for general cutting. ● Ball Nose End Mills: Used for contouring and 3D shapes. ● Corner Radius End Mills: Ideal for reducing stress on part corners. Face Mills Face mills are used to flatten surfaces and provide a smooth finish. Roughing Mills Roughing mills remove large amounts of material quickly, making them ideal for the initial cutting phase. Slot Drills Slot drills are designed to cut slots and pockets in materials. Fly Cutters Fly cutters are used for finishing operations and produce an extremely smooth surface. Thread Mills Thread mills cut internal or external threads in materials. Reamers Reamers enlarge holes and improve precision. Drill Bits Although CNC milling machines can perform drilling, specialized drill bits are sometimes used to create holes.   Top 8 Factors That Affect the Cost of a CNC Milling Machine The cost of a CNC milling machine varies significantly based on its size, capabilities, and additional features. While entry-level machines may cost a few thousand dollars, high-end industrial models can range into the hundreds of thousands.

Preload adjustment of ball screws is a key step to ensure their high precision, high rigidity and long life. The role of preload is to eliminate the gap between the ball and the raceway, reduce the reverse clearance (backlash), and improve the axial rigidity and vibration resistance of the system. However, excessive preload may cause heating, increased wear and even jamming, so the adjustment must strictly follow the technical specifications. The following are the detailed methods and precautions for preload adjustment: 1. Purpose of preload adjustment Eliminate axial clearance: Ensure that the screw has no empty stroke when moving forward and backward. Improve rigidity: Enhance the system's ability to resist deformation due to load changes. Extend life: Reasonable preload can evenly load the ball and avoid local wear.   Reduce vibration and noise: Reduce impact and abnormal noise caused by clearance. 2. Main methods of preload adjustment a. Double nut preload method (most common) Principle: Apply opposite axial forces through two nuts to squeeze the ball into contact with the raceway. Steps: Install double nuts: Install two ball nuts in reverse on the same screw shaft. Apply preload: rotate the two nuts to bring them closer together, compress the elastic element in the middle (such as a disc spring) or directly lock them through the thread. Adjustment method: Torque control method: tighten the nut to the specified torque value with a torque wrench (refer to the manufacturer's data). Displacement control method: measure the distance between the two nuts and adjust to the preset compression amount (usually 1%~3% of the lead). Lock the nut: use a locking washer or thread glue to fix the adjusted position. b. Shim adjustment method Applicable scenarios: single nut structure or occasions where the preload needs to be accurately adjusted. Steps: Add a shim between the nut end face and the mounting seat. Change the axial relative position of the nut and the screw by increasing or decreasing the thickness of the shim, and compress the ball and raceway. The preload needs to be tested repeatedly until the target value is reached. c. Spacer adjustment method Principle: add a spacer (sleeve) of a specific length between the double nuts, and control the preload by changing the length of the spacer. Advantages: High preload accuracy, suitable for equipment with high rigidity requirements (such as CNC machine tools). Steps: Measure the original spacing between the two nuts. Calculate the required spacer length based on the preload amount (usually the required compression amount = spacer length - original spacing). Install the spacer and lock the nut. d. Variable lead method (preload type ball screw) Principle: The manufacturer changes the lead of the ball circulation path to make the ball preload in the nut.   Features: Users do not need to adjust, and can obtain standard preload by direct installation (need to select according to the load). 3. Key parameters for preload adjustment Preload level: usually divided into light preload (C0/C1), medium preload (C2/C3), heavy preload (C5), which needs to be selected according to the load and accuracy requirements. Preload amount calculation: Preload amount ≈ 0.05~0.1 times the elastic deformation corresponding to the rated dynamic load. Empirical formula: preload = (5%~10%) × lead (refer to the manufacturer's manual). Preload detection indicators: Axial rigidity: The displacement after applying external force must be less than the allowable value (such as 1μm/N).   Reverse clearance: measured with a micrometer, the target value is usually ≤5μm. IV. Detection and verification after adjustment Torque test: Manually rotate the screw to feel whether the resistance is uniform and avoid local jamming. Use a torque meter to measure the driving torque and compare it with the manufacturer's recommended range (re-adjustment is required if it exceeds the limit). Reverse clearance detection: Fix the micrometer contact to the nut, move the screw in the forward and reverse directions, and record the displacement difference. Temperature monitoring:   Run without load for 30 minutes to check whether the temperature rise is normal (generally ≤40℃). V. Precautions Avoid over-preloading: Excessive preloading will cause a sharp increase in friction heat, accelerated wear and even sintering. Lubrication management: After preload adjustment, it is necessary to add an appropriate amount of grease. It is recommended to use high-speed and high-load lubricants. Environmental adaptability: The preload amount needs to be re-checked in high or low temperature environments (affected by the thermal expansion coefficient of the material).   Regular maintenance: Check the preload status every 300-500 hours of operation and readjust it if necessary. VI. Common problems and solutions Problem 1: Large running resistance after preload adjustment Cause: Excessive preload or insufficient lubrication. Solution: Reduce the thickness of the gasket or the length of the spacer sleeve and increase lubrication.   Problem 2: The reverse clearance still exceeds the standard Cause: The nut is worn or the screw shaft is bent. Solution: Replace the nut, straighten the screw or replace a new screw.   Problem 3: Abnormal noise and vibration Cause: Uneven preload or broken balls. Solution: Readjust the preload and check the ball circulation system.     Through the above understanding of ball screw preload, if you want to learn more, please contact us, we are online 24 hours a day to serve you.

Due to its high strength, corrosion resistance and aesthetics, stainless steel is widely used in machinery manufacturing, architectural decoration, home appliances and other fields. However, its high hardness and strong toughness also make its bending process more challenging. ZYCO will introduce in detail how to use a bending machine to efficiently and accurately complete the bending process of stainless steel sheets. I. Characteristics and difficulties of stainless steel bending 1. Material characteristics - Stainless steel (such as 304, 430, etc.) has high hardness and high yield strength, and requires greater pressure when bending. - It has high resilience and is prone to angle rebound after bending, which requires compensation adjustment. - The surface is easily scratched, and attention should be paid to the contact protection between the mold and the plate. 2. Common problems - Rebound: The angle of the plate rebounds after bending, resulting in the actual angle being smaller than the target angle. - Cracking: If the bending radius is too small, the outer tensile stress is too large, which may cause edge cracking. - Surface scratches: The stainless steel surface is damaged due to improper mold or operation.   Ⅱ. Working principle of bending machine The bending machine applies pressure to the plate to make it plastically deform through the cooperation of the upper die and the lower die. The hydraulic or electric driven pressure system can accurately control the bending angle and depth. Key parameters: - Pressure (tonnage): Calculate the required pressure according to the thickness and material of the plate. - Bending angle: Achieved by adjusting the upper die descending depth or the lower die opening distance. - Bending radius: Determined by the R angle of the die, it must be greater than the minimum bending radius of stainless steel (usually 1-2 times the plate thickness). Ⅲ. Stainless steel bending operation steps 1. Preparation - Choose the mold: give priority to high-hardness molds (such as 42CrMo steel) to avoid mold wear and scratching the stainless steel surface. - Clean the plate: remove oil or impurities on the stainless steel surface to prevent indentation. - Calculation parameters: Determine the pressure (P) according to the plate thickness (T) and material: the empirical formula is (P = T*T*650 / V) (V is the lower die opening width), which is the bending pressure required for a 1-meter-long carbon steel plate, and stainless steel is twice that of a carbon steel plate. - Set the compensation angle (usually 1°~3° larger than the target angle to offset the rebound).   2. Adjust the equipment - Install the appropriate upper and lower molds to ensure centering. - Enter the parameters (pressure, angle, stroke) and try bending, observe the rebound amount and then fine-tune.   3. Bending operation - Align the stainless steel plate with the center line of the lower mold and fix the position. - Start the bending machine, slowly press the upper die down to the set position, and hold the pressure for 1~2 seconds to release the stress. - Bend step by step (such as multiple small angle bends) to avoid cracking caused by one-time forming.   4. Inspection and correction - Use an angle ruler to measure the bending angle and compare it with the target value. - If the angle is insufficient, increase the compensation value; if there is an indentation on the surface, check the mold finish or add a protective film.   IV. Precautions 1. Avoid surface damage - Apply a polyurethane protective film on the surface of the mold or plate. - Clean the mold regularly to prevent iron filings from scratching stainless steel. 2. Control the bending radius - The minimum bending radius of stainless steel must be greater than that of carbon steel. It is recommended to refer to the material manual (such as the R angle of 304 stainless steel ≥1.5T). 3. Lubrication and cooling - Apply special lubricants (such as chloride-containing stainless steel oil) when bending to reduce friction and heat accumulation. 4. Safe operation - Wear protective gloves and goggles to prevent cuts on the edge of the plate or debris from flying. - Check whether the hydraulic system pressure is stable before bending.   V. Solutions to common problems Excessive rebound: - Increase the compensation angle or use the "bend and then press back" process. - Choose a CNC Press Brake with compensation function.   Edge cracking: - Increase the bending radius or choose annealed stainless steel (such as 304 soft state). - Bend perpendicular to the rolling direction of stainless steel to reduce stress concentration.   Surface indentation: - Use polished molds or pad soft materials (such as PVC film) on the mold contact surface.   VI. Summary Stainless steel bending processing has high requirements for equipment accuracy, mold selection and operating specifications. By reasonably adjusting parameters, compensating for rebound in steps, and paying attention to surface protection, the quality of the finished product can be greatly improved. For high-precision requirements, it is recommended to use a CNC press brake to achieve automatic control of complex bending processes through programming.
