Six Axes Control using AC Servo Direct Drives (Includes electronic index drive for synchronization of cutter and work rotation):
Stroking speed.
Stroke position.
Work spindle rotation.
Cutter spindle rotation.
Infeed speed and position.
Stroke Length
Adaptive process control for:
Automatic compensation of temperature dependent center distances changes.
Hydraulic pressure requirement for stroking.
Servo Stroke positioning of cutter spindle:
Operator I automatic pre-set elevating.
Operator pre-set tool height setting.
Display of actual and available adjustment.
Minimum input increment 0.025 mm (.001 ").
Automatic cutter positioning to return cutter to top of stroke.
Stroke positioning adjustment.
Number of Cuts:
Selectable, 1-6 cuts, Infinitely variable speeds available each cut.
Programmable, multi-surface cutting capability
Infinitely variable speeds & feeds:
Stroking speeds infinitely variable with quick return for increased productivity within ranges of 12-300 SPM
Rotary feed rate: 0.0025 mm to 6.35 mm/stroke (0.0001" - 0.250") per stroke per inch of cutter diameter up to 4 rpm of cutter spindle. Reduced rotary feed during infeed to any value including plunge infeed for improved tool wear.
Cutter spindle and worktable rpm: 20
Infeed rate: Programmable, Diminishing. (a)Range: 0.001 - 0.50 mm (0.0001" - 0.020") per stroke and (b) Maximum Rate: up to 305 mm (12.0") per minute with constant or diminishing infeed rate for increased production and reduced tool wear.
Oriented Stiffness Back-Off™: Servo driven with unique oriented stiffness design.
Function controls and keypads for online direct entry of gear shaping data. Switchable metric/inch operation. Programmable tool and work offsets.
