Precision Control Method for Deep Hole Machining

Deep hole machining is common in precision mechanical components. Deep holes easily lead to rough hole walls, aperture deviation and poor coaxiality, affecting subsequent assembly.

Processing Difficulties: Chip removal is difficult in deep hole machining. Cutting heat is concentrated, easily causing larger aperture and poor coaxiality.

We optimize tool selection and cutting parameters, reasonably control feed speed to ensure smooth chip removal. Multi-feed processing is adopted to control inner wall finish and coaxiality of holes.

Aperture, hole position and coaxiality are inspected by height gauge, inner diameter micrometer and CMM after machining.

We provide deep hole precision machining services for automation, medical and aerospace equipment components, supporting sample and bulk orders.
