⚙️ Machine Introduction
CNC Centerless Grinding Machine
Machine Detail

Every centerless grinder is derived from application requirements.

  • The HC full series of centerless grinders have corresponding solutions for a grinding range of 0.08 to 200mm.
  • Hydrodynamic spindles, hydrostatic spindles, and bearing spindles are available for selection.
  • Hydrostatic guideways and rectangular square guideways are provided for different applications.
  • The CNC series with various combinations of 1 to 6 axes can meet various grinding requirements.
🚀 Machine Applications

The applications of centerless grinders are everywhere. They are essential for precision manufacturing across various industries.

  • Through grinding: Suitable for cylindrical shaft parts of various sizes.
  • Stop grinding: Ideal for multi-stepped parts of various sizes and parts with complex shapes.
Grinding Applications
🏗️ Product Structure & Tech
Structure Overview

Track Systems

  • Double V Tracks: Manually scraped for excellent movement performance throughout the entire stroke.
  • Rectangular Square Tracks: Used for large-scale grinders, combining sliding sensitivity with ultra-high rigidity.
  • Hydrostatic Tracks: Features orifice throttling where the track floats on high-pressure oil film (friction coefficient < 0.001), achieving feed accuracy of 0.0001mm.
Spindle

Spindle Technology: Core shafts are made of Japanese SNCM-21H alloy steel. Hydrostatic spindles are supported by a high-pressure oil film, eliminating contact friction and improving shock absorption for high-speed cutting.

Rolling Bearing Spindle: Utilizes ultra-precision double row cylindrical roller bearings. The unique design eliminates the need for a flange, perfect for high-precision grinding with zero maintenance requirements.

Bearing
Trimming System

Trimming & CNC: The trimming seat is driven by hydraulic pressure or servo motors. The CNC control system allows for automatic dressing and compensation for complex shapes, reducing manual operational difficulty.

Frequently Asked Questions
What is the grinding range of the HC series machines?
The HC full series of centerless grinders can handle a grinding range from 0.08mm to 200mm, depending on the specific model and configuration.
What types of track structures are available?
We offer three main types: Double V tracks for stability, Rectangular Square tracks for large-scale ultra-rigidity, and Hydrostatic tracks for high precision and long service life.
How accurate is the CNC feed system?
The CNC system provides a minimum setting of 0.0001mm with a feed accuracy of 0.001mm, ensuring high-precision results for complex parts.
What is the benefit of the Hydrostatic Spindle?
The hydrostatic spindle is supported by high-pressure oil film, which means zero contact friction. This reduces power consumption while significantly improving accuracy and vibration absorption.
Can these machines handle complex shaped workpieces?
Yes, by using stop-grinding mode and the CNC control system, the machine can realize automatic dressing and compensation for various complex shapes.
