Retrofit at SHW
SK 50 DIN 69871
Universal machining center SHW-PoweSpeed 6, Machine number 5403, Construction year: 2012
Basic machine with the traverse paths:
Machine stand horizontal-longitudinal X = 10.000 mm
Headstock carriage vertical Y = 3.100 mm
Headstock horizontal-transverse Z = 1.500 mm
Machine bed x-axis
**Without X-axis/machine bed**
X-axis can be freely configured. Originally the machine was equipped with X=10.000mm. The energy supply chain would be available for this purpose.
Machine stand Y-axis
Stand in steel-welded construction with rolling compact guide
Two liquid-cooled feed motors in the Y-Axis ensure fast acceleration and high rapid traverse speeds at a constant operating temperature. Two measuring systems on the stand guarantee maximum accuracy when extending the headstock (DynamicDrive). Stand is protected against chips and cooling water with telescopic steel cover. Guideway width in Y-direction 900 mm.
Headstock carrier Y-axis and headstock Z-axis
Headstock support in ST 52 steel construction (Y-axis), guided on the machine stand with two hardened rolling compact guides. Headstock in cast iron construction from GGG 60 (Z-axis) with two opposite rolling compact guides. To counteract a tilting of the vertical unit, the guideways of the Y and Z axes are arranged as close as possible to the stand.
Drive via 2 vertical ball screw spindles with separate drives, measuring systems and CNC axes. This ensures a long-term, highly dynamic acceleration of the vertical unit.
Digital feed single drives for accurate contour work on AC motors with Constant torque, feed and rapid traverse range steeples from: X + Y + Z –Axis 2-30.000mm/min, acceleration values in all axes 3.5 m / s2.

Switching the internal or external coolant supply from the coolant water on air.
Collision monitoring system 2-channel
2 Monitoring channels: 1. Collision (channel 1)
2. Tool monitoring (channel 2)
A piezo force sensor measures all deformations during machining. The monitoring device analyzes the signals.
Channel 1 Collision:
Channel 1 can be programmed manually from the operator thru the whole machining process. The operator can adjust the deformation stop point. If the deformation value detected by the piezo force sensor is higher than the programmed value, the machine stops immediately. This gives prevention of damage following a collision in the event of program, set up or user error.
Channel two monitors all tool specific values programmed by the operator in the CNC control unit. This gives prevention of major tool damages when for example the tool is blunt.
