for hydraulic cylinder holes
from ø38 to 300 mm

application

combined skive-burnishing tool type wsg was developed for the inner-machining of cylinder tubes or other workpieces with very short processing time.the machining takes place in one step, as the burnishing-skiving head only works in one direction, so that the rolling and burnishing process happens at the same time.

using a switching system –featured by the machine- tools can move back in fast movement without spoiling the already  rolled surface.

tools are adjustable with a precise repeatable diameter setting.

examples for application

• seamless steel tubes made of material st 52 or st 35
• welded precision tube (st. 37)
• seamless steel tubes cold drawn or cold welding
• dom tubes of material
