For Short Cylinders (L/Ø ≤ 15)
- 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.
- SKOC skiving head:
- 3 knives with consecutively arranged cutting inserts.
- Integrated in tool holder: Control piston equipped with MQL supply. After activating the MQL-supply knives are automatically adjusted to working position. After switch off they retract into the idle position without damaging the peeled surface.
- MQL nozzles inject cooling lubricants on high speed into the pe eling unit which supports chip removal in feed direction.
- GZC burnishing tool:
- See standard burnishing tool type G.
- Here equipped with internal washing unit.
- MQL supply:
- For both tools through boring bar.
