Deep drilling

- COOPERATION FOR EXTERNAL CUSTOMERS

This involves drilling rotary parts, both through and blind holes.

Drilled materials:

– steels, even those refined to a strength of 1200 MPa
– stainless steels
– duralumin
– brass

We perform the drilling technology with a monolithic drill with internal high-pressure chip washing on a special three-spindle machine. The holes can then be reamed with a high precision of + 0.03 mm. The tolerance after drilling itself is – 0.02 / +0.05 mm depending on the drilled material. Surface roughness Ra 1.6.
