High Precision CNC Centerless Grinder

 

MX-L600 Series High Precision CNC Centerless Grinder is a cutting-edge machine that revolutionizes the approach to centerless grinding. Engineered for industries where micron-level accuracy is non-negotiable, MINGXU's High Precision CNC Centerless Grinder combines advanced CNC control, rigid cast iron construction, and intelligent grinding cycles to deliver consistent surface finishes down to Ra 0.16μm - trusted by manufacturers across automotive, aerospace, medical, and precision bearing sectors worldwide.

 

The system uses a high-resolution linear grating scale and a precision servo system to achieve tolerances from the micron (μm) to the sub-micron level. Moreover, the roundness can be within 0.1μm.

 

The working bed is constructed using polymer concrete or high-grade cast iron, and it features excellent vibration-damping performance to ensure long-term stability.

 

High-accuracy CNC centerless grinder product series models: L600, M500, M400, M200, S250, S200, S150. Can do customized services.

 

 

 

The MX-L600 high-precision CNC centerless grinder does not require centers or chucks to hold the workpiece. The workpiece is placed between the grinding wheel (grinding wheel), guide wheel, and support plate:
• Grinding wheel: Rotates at high speed, responsible for removing material.
• Guide wheel: Rotates at a relatively slower speed, responsible for driving the workpiece rotation and controlling its feed speed (through grinding mode) or positioning (infeed grinding mode).
• Support plate: Supports the workpiece and maintains its center height.
• CNC advantages: The CNC system can precisely control the guide wheel speed, grinding wheel feed, dresser movement trajectory, and the linkage of each axis, thereby achieving complex contour grinding or high-precision dimensional control.

 

 

Our high-accuracy CNC centerless grinder typically supports two main grinding modes, which can be quickly switched via a program:

Through-feed Grinding
• Suitable for long, straight cylindrical workpieces (such as pins and piston rods).
• The workpiece enters from one end, passes through the grinding zone, and exits from the other end.
• CNC controls the guide wheel angle and speed to adjust the feed rate, suitable for mass production.

 

In-feed/Plunge Grinding
• Suitable for workpieces with stepped, tapered, or non-cylindrical contours.
• The workpiece's axial position is fixed, and the grinding wheel radially cuts in for grinding.
• CNC can control multi-axis linkage, allowing for the grinding of complex-shaped surfaces.

 

 

• High Precision and Consistency: The CNC system eliminates human error through precise control, achieving micron-level (μm) repeatability and ensuring high precision and consistency for each product in mass production.

• High Automation: It can be equipped with automatic loading and unloading mechanisms (robotic arms or vibratory feeders) and online measuring instruments (active measuring instruments) to achieve "unmanned" or minimally manned workshops.

• Intelligent Dressing: Built-in diamond dresser; the CNC can automatically dress the grinding wheel and guide wheel according to preset programs, maintaining the sharpness and geometry of the grinding wheel.

• Data Management: Supports storing multiple processing parameters (recipes), facilitating rapid changeover for different workpieces; it has fault diagnosis and data recording functions for easy quality traceability.

• Wide Adaptability: Suitable not only for steel parts, but also for difficult-to-machine materials such as cemented carbide and ceramics.
