Grinding Capabilities

Surface grinding removes a controlled amount of material from a flat surface using a rotating grinding wheel. The process is used to establish accurate reference planes and improve dimensional relationships between component surfaces.

For vertically positioned pins and cylindrical parts, end-face grinding can help control:

• Overall component length
• End-face flatness
• Parallelism between two ends
• Squareness to the part axis
• Height consistency across a batch
• Surface finish of locating faces

Typical components include:

• Mold pins
• Ejector pins
• Core pins
• Guide pins
• Precision punches
• Small shafts
• Cylindrical inserts
• Tooling and fixture components

The fixture helps maintain the workpieces in a stable and organized arrangement during grinding. Multiple parts can be checked and processed as one group, supporting repeatability across components produced for the same assembly or mold set.

Role in Our Manufacturing Process

Surface and end-face grinding may be performed after turning, heat treatment, cylindrical grinding, or rough cutting. The process provides accurate datum surfaces for subsequent assembly, fitting, measurement, or additional machining.

A typical workflow may include:

1. Preliminary machining
2. Heat treatment when required
3. Outside-diameter grinding
4. Fixture positioning
5. Surface or end-face grinding
6. Height and flatness inspection
7. Final dimensional verification

Keeping this operation in-house allows the grinding team to coordinate part length, machining allowance, fixture layout, and inspection requirements according to the actual drawing and assembly conditions.
