The CNC Lathe CKA6136 has a level configuration. The motions
of cross (X) and longitudinal(z) axis are controlled by CNC system.
The machine is suitable for such machining process as automatically
turning internal and external cylindrical surface, curve, end face,
slot, chamfer, metric and inch thred, thread on end face, conic thread,
etc for sorts of shaft parts and disc parts. The machine can adopt FANUC-0TD,Yaskawa
R2J50L CNC system as well as other CNC system required by customers,
comprising corresponding servo motor respectively as drive unit, and
taking pulse encoder as measuring unit to consist of semi-closed loop
of CNC system. The spindle drive has three types for the buyer to choose.
The first type is manual type which adopts manual shift gears. The second
type is frequency conversion type which abopts frequency conversion
motor to realize infinitely variable speed change (no shift gears).The
third type is servo type which adopts servo motor for infinitely variable
speed change. The machine comprises vertical 4-position electrical tool
post, manual chuck and manual tailstock. The surfaces of saddle and
slide plate coupling to the guideways are plastic coated. The makes
such static and dynamic performance as rigidity and frictional damping
coefficient of the feed units get the best status, makes the moveable
parts get accurate minute movement, and facilitates improving machining
accuracy and service life of the guideways. The braking of the spindle
is realized by the braking device installed at the end of the motor
shaft. After finishing auto-cycle, the magnet of the braking device
at the end the motor shaft is energized and creates magnetic force to
attract and engage the braking disc to realize braking .After the braking
is finished, the braking device is released and the spindle can rotate
again. Full cover is adopted by this machine to protect operator against
the splash of the chips and the coolant.
