Internal burnishing tool IT8 / IT9, 1 – 30 µm

Complete machining on CNC-lathes or machining centers. Skiving and burnishing in one setting before or after machining the cylinder ends. Internal machining on deep hole drilling machine not required. GZC Tools: See burnishing tools type G, for this usage equipped with internal washing unit and a special tool holder compatible with boring bar. Accessories: MQL-pump with installation service. Reliable, high-precision operation. Achieves a diameter tolerance of IT8 or IT9. Significantly reduced side-times. Transportation of components to a deep hole drilling machine is no longer necessary. Tool change on CNC-lathes and machining centers is much quicker than on deep hole drilling machines High investment costs for a deep hole drilling machine can be eliminated, which enables small- and middle batch manufacturers to efficiently produce cylinder liners or complete cylinders. Separate short tools. SKOC skiving head: Achieves surface finish of Rz = 15 30 micron. Change of cutting insert and central diameter adjustment without removal of knives. Controlling of knives by MQL pressure (no separate controlling system required). Connection to boring bar with control connection (ECOROLL W connection). GZC burnishing tool: Achieves surface finish of Rz < 1 micron. Simple change of wear parts.
