Grinding Capabilities

The workshop supports centerless grinding of materials such as:

• Tungsten carbide
• High-speed steel
• Tool steel
• Stainless steel
• Hardened alloy steel
• Other grindable metal materials

Typical components include:

• Tungsten carbide rods
• High-speed steel rods
• Guide pins and guide posts
• Core pins
• Ejector pins
• Precision punches
• Small shafts
• Cylindrical tooling components

The process can be used to improve:

• Outside diameter accuracy
• Roundness
• Cylindricity
• Straightness
• Surface finish
• Diameter consistency across a batch

Through-feed grinding is generally suitable for straight cylindrical components without major shoulders. In-feed grinding may be used for parts with steps, profiles, or localized grinding areas.

Role in Our Manufacturing Process

Centerless grinding is integrated with material preparation, turning, heat treatment, end-face grinding, and dimensional inspection. It is often used to bring round stock or semi-finished components close to their final outside diameter before additional finishing or assembly.

A typical workflow may include:

1. Raw rod or component preparation
2. Heat treatment when required
3. Initial straightness inspection
4. Centerless rough grinding
5. Centerless finish grinding
6. End-face or profile processing
7. Diameter, roundness, and surface inspection

The multi-machine arrangement enables different materials, component sizes, and production batches to be processed in parallel. In-house grinding also allows wheel condition, grinding allowance, feed settings, and inspection results to be adjusted according to each component’s material and tolerance requirements.
