Centerless Grinder

CNC centerless grinders, also known as CNC centerless grinding machines, are sophisticated pieces of equipment designed to deliver high-precision surface finishing on cylindrical workpieces. 

The term "centerless" refers to the process by which the workpiece is supported by a work rest blade and regulated by a guide wheel, instead of being held between centers. This method allows for a high degree of uniformity and consistency in the grinding process, making it ideal for mass production environments.

Precision centerless grinding is a specialized technique that ensures the workpiece is ground to extremely tight tolerances. It involves the use of a high-speed grinding wheel that removes material from the surface of the workpiece, achieving a mirror-like finish and dimensional accuracy that is often unattainable with other machining processes.

CNC centerless grinders are equipped with computer numerical control systems that allow for automated and repeatable grinding cycles. This automation not only increases efficiency but also reduces the potential for human error, ensuring consistent quality in every part produced.

Product Advantages and Features of the Centerless Grinder 

Zhonglun Precision's centerless grinding equipments are renowned for their strong rigidity and high precision, making them ideal for the through grinding of bearing rings and the multi-step cutting grinding of shaft-type components. These centerless grinding equipments are equipped with advanced features that ensure high dimensional accuracy, roundness, and surface roughness, with a system accuracy resolution of 0.1um.

1. Models and Automation：Our centerless grinding machines come in two models, each offering a unique combination of technology to suit different production needs:

Siemens 828D Numerical Control System paired with a servo motor and ball screw control for precise movement and positioning.

Siemens 828D Numerical Control System combined with a linear motor and optical control for ultra-precision and speed.

Both models are designed to enhance automation, allowing for increased production efficiency and reduced manual intervention.

2. Advanced Support Structures：The grinding wheel and guide wheel of our centerless grinder machines utilize a double support structure, ensuring high dimensional accuracy post-grinding. This design contributes to the machine's reliability and longevity, with a low failure rate that is supported by our comprehensive after-sales service.

3. Automated Shape Repair：Our centerless grinders are equipped with an automated shape repair function. By simply inputting the required data, the machine can autonomously adjust the grinding wheel and guide wheel to meet the specified shape requirements, ensuring safety and reliability in the production process.

4. Self-Diagnosis and Alarm System：Incorporating a self-diagnosis function with a text display alarm, our centerless grinding machines offer robust system protection. This feature allows for quick identification and resolution of potential issues, minimizing downtime and ensuring continuous operation.
