Introduction

- Internal Grinding

Internal grinding is to grind the hole of the workpiece to meet size precision and surface roughness. In the knife tooling processing, some hard and brittle steels are hard to achieve precision requirement, especially when processing a taper hole, deep hole or blind hole, so a proper grinding process is needed. When grinding an internal hole, the inner space of the hole is usually small, so the stock removal and heat discharge become significant.

Key factor: Precision, stability, surface roughness, stock removal and heat discharge.
