For Short Cylinders (L/Ø ≤ 15)

Characteristics

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: Coolant-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.
SKIOC skiving head:
- Achieves surface finish of R_z = 15 – 30 micron.
- Change of cutting insert and central diameter adjustment without removal of knives.
- Controlling of knives by coolant pressure (no separate controlling system required).
- Connection to boring bar with control connection (ECOROLL W connection).
GZ burnishing tool:
- Achieves surface finish of R_z < 1 micron.
- Simple change of wear parts.

SKIOC skiving head:
- Based on OMEGA system.
- 3 knives with consecutively arranged cutting inserts.
- Integrated in tool holder: Control piston equipped with Coolant supply. After activating the Coolant supply knives are automatically adjusted to working position. After switch off they retract into the idle position without damaging the peeled surface.
- Coolant nozzles inject cooling lubricants on high speed into the peeling unit which supports chip removal in feed direction.
GZ burnishing tool:
- See standard burnishing tool type G.
- Here equipped with internal washing unit.
Coolant supply:
- For both tools through boring bar.
