ACRA Toolroom Lathe w/ Electronic Threading - CTL-618E
ACRA Machinery CTL-618E Lathe
Features:
- Computer-controlled servo motor linked directly to the leadscrew
- Display shows spindle speed, cutting feed rate and DRO functions
- Good for pitch and module turning processing without any gears in gearbox. Easy exchange of inch and metric system, accuracy goes up to three digits after decimal point.
- Digital data shows R.P.M. of spindle and tool infeed to let operator arrange best possible turning process combination. Hand scraped turret-column ways.
- Digital data shows electric current for easy checking overload turning
- Rapid retract function available for shortened pitch module turning processing time
- The lead screw is driven directly by servo- motor. Through operation of interface, a spindle decoder is used to transfer the motion of lead screw to rectilinear one. The L.C.D. touch pad showing the data is applied to control.
- Rapidly returning to the origin is executed according to the principle of temporarily coming off the tracking mode
- Feeding rate per minute of auto feed is calculated with modbus communication protocol interior message data of the converter, so that users' cutting precision is available much more easily.
