  ※Notice :
1.To keep improving and developing new functions, Kuen Jeng reserves the rights to change specifications without notice.
2.Due to varying cutting conditions, actual results may be greater or less than those listed.

  Sliding Head
 
  • ‧The spindle head moves on two linear ways with a large span design to achieve maximum stability
       and smoothness.
  • ‧The spindle head movement is driven by a servo motor for highly accurate positioning.
  • ‧A high precision spindle permits accurate machining and allows continuous, long time operations.
 
  Direct Drive Spindle
  • ‧Spindle speed range 500 – 10,000 rpm.
  • ‧The high speed direct-drive spindle permits full power
       transmission without backlash problem.
 
  Automatic Bar Feeder (optional)
The machine is equipped with an automatic bar feeder that allows the machine to perform fully automatic operations. This results in labor-saving, increased efficiency and productivity.
 
  C-axis Contouring Function
  • ‧Both main and sub-spindle feature C-axis functions,
       allowing for contourmachining.
  • ‧Indexing accuracy for main and sub-spindle is 0.001°,
       providing highly accurate contour machining.
  C-axis Contour Machining
 
  Rotary Guide Bushing
Rotary Guide Bushing
The rotary guide bushing in the sliding head design may assure stability, machining accuracy and surface finish, especially when machining long workpieces.
The sliding tool structure features no guide bushing design, which minimizes the material length of residual, and saves machining cost.
  Hydraulic Brake
  The main spindle orientation is equipped with an hydraulic brake
for increasing accuracy in spindle orientation.
