Travelling column milling machine

SHW PowerSpeed 4000

Base machine / Travel paths
X = 4,000 mm, Y = 1,600 mm, Z = 1,600 mm.

The machine features a stable, flat bed for quick and precise movement of the machine stand in the X-axis. Hardened, rolled compact guides, a 1,200 mm guide rail width, and a rack and pinion drive with two electronically pre-tensioned servomotors ensure accuracy and dynamics.

The machine stand is designed as a steel welded structure with rolled compact guides. Liquid-cooled feed drives, two measuring systems, and telescopic steel covers provide precision, constant temperature, and protection against chips and coolant. The spindle headstock slide and spindle headstock are made of GGG 60 and are stably guided via long guides.

The dual-spindle drive is provided by two vertical ball screws with separate drives, measuring systems, and CNC axes. Feed rate/rapid traverse: 2–30,000 mm/min, acceleration: 3.5 m/s². Direct, non-contact linear measuring systems ensure high manufacturing accuracy.

Automatic universal milling head
Diagonal milling head 45° with C and A axes, positionable to 0.01°, liquid-cooled, GGG-60 cast iron construction. C-axis ±180°, A-axis ±360°, separate axis drives, helical gearing with ±3 sec indexing accuracy, hydromechanical tool clamping, as well as internal and external coolant supply. Drive via a frequency-controlled, liquid-cooled main motor.
