Task:

Machining base frames for knitting machines

Solution:

  • Around 20 racks are stored in a high rack axially in front of the machine
  • The workpiece is inserted into the hydraulic clamping device by means of a gantry loader
  • Complete machining by means of 2 swivel heads with HSK A100 spindles
 

Special characteristics:

  • 2 angular milling heads above a stable four-point support on the spindle with integral HSK A63 tool clamp
  • Each angular milling head has its own 32-fold tool plate
 

Traverse ranges of each travelling column:

X-traverse range: 6200 mm
Y-traverse range: 900 mm
Z-traverse range: 800 mm

Spindle:

Main spindle drive (with 40% DC): each 45 kW
Torque (with 40% DC): each 286 Nm
Speed range: each 7500 1/min

Tool changing system:

XTS tool magazines with each 46 tool places (HSK A100)
