KL 435

Max. turning dia: 550 mm

Max. turning length: 1 100 mm

Max. output S1: 22 kW

Modular machine concept

Tailstock with a separate rotary bushing for using a fixed point (rigid mounting)

Full C-axis

High torque on the main spindle

Hydraulic unit with proportional valves – setting the clamping pressure at the chuck and the tailstock quill on the machine control panel

Machine control panel Siemens Sinumerik 828D

High rigidity of the machine skeleton

Large stroke of Y-axis

High dynamics and rapid feed of individual feed axes

Components spreading heat and noise placed at the rear of the machine

Setting the chuck jaw stroke on the machine’s control panel
