Faster than conventional honing

SRB (Skiving & Roller Burnishing) is the high-productivity alternative to honing for deep-hole finishing. The front inserts remove a controlled stock allowance and correct roundness and straightness; the roller set immediately behind cold-compresses the freshly cut surface, flattening micro-peaks into a dense mirror finish. Cutting and surface densification happen before the tool leaves the tube — the bore is finished when the tool exits.

02 / SURFACE STRENGTH

Roller burnishing work-hardens the bore surface, raising hardness by roughly 30% and extending seal and component life.

03 / SIZE CONTROL

Pneumatic or hydraulic expansion opens inserts and rollers together; both retract on release so the finished bore is never scratched.

Specifications on this page are compiled from the MIRAFU catalogue. Actual capability depends on material, machine rigidity and coolant supply — final selection is confirmed by our engineers.

01 / SINGLE PASS

Skiving and burnishing are combined, eliminating a second set-up and the entire honing step — cycle time cut by more than 60%.

Same bore size and finish requirements — delivered in one operation, on one machine, with far better batch consistency.
