Basic machine UniForce 7000C

Travels of the machine

Machine column horizontal-longitudinal                      X = 8.000 mm

Spindle stock slide vertical                                          Y = 7.100 mm

Spindle headstock horizontal-cross                            Z = 1.800 mm


Machine bed X-axis

Basis for a fast and secure movement of the machine column in X-direction is our machine bed in flat bed design. A distance of 1.400 mm between the linear guides (RUE 65) grant highest accuracy.

Inside positioned energy chain, as well as rack and pinion drive ensure production security for decades.

Electrically driven X-axis using two synchronized motors.



The machine column is of a compact, buckling-restistant welded construction. The guides on the column are combined sliding and roller guides with hardened flat bearings. The guides are protected against swarfs and water by means of telescope covers.


Headstock slide

GGG 60 cast iron design with hydraulic counterweight, guided on the column with screwed and hardened slide ways. Long guidings lea to the machine column and the spindle stock and grant highest force transmissions at a constant quality. In order to avoid a tilting of the column, the Y and Z Axis are arranged as close as possible.


Headstock Z-axis

Cast iron design made of GGG 60 with two opposed anti-friction guideways.The headstock incorporates the C-Axis, which can be continuously swivelled, with integrated interface for media connection.

This is prerequisite for automatic changing of different milling heads:

         – Axis speed 20 rpm

         – Continuous swivelling range from 0° to 360°

         – Axial clamping torque 20.000 Nm

         – Axial torque 800 Nm at 100% ED (duty ratio)

         – Indexing accuracy 6 sec



Electro-mechanical control unit using 2 vertical ball screws with separate drives, measurement systems and CNC axes to ensure a long-lasting, accurate, co-planar and low-maintenance movement of the headstock.


Drive System

Individually operating digital feed drives with AC motors ensure a high-precision processing with a constant torque, feed and rapid feed continuously variable from:

Y- and Z-axis:               2 to 24.000 mm/min.

X-axis                           2 to 36.000 mm/min

Acceleration in all axes 2 m/s²


Measurement System

Direct contactless measuring with linear measurement systems for a high precision machining.


Main Drive

Frequency controlled liquid cooled AC motor. Due to direct power transmission WITHOUT gears additional heating and wear is avoided.

42 kW drive power at 100 % duty, 63 kW at 40 % duty

Torque: 1.003 Nm at 100 % duty, 1.504 Nm at 40 % duty

Speed range 22 – 5.000 rpm

Power Saving Mode

All the SHW machines are provided with a build-in energy-saving mode, setting the machines into standby according to pre-set time intervals. A large number of aggregates can be switched-off completely with the energy-saving mode (for example the coolant system, the swarf conveyor and the hydraulics) thus considerably reducing the power consumption to under 1kW.

Spindle Version 400mm Orthogonal Head

Longer execution of the milling spindle for automatic universal milling heads in orthogonal design. In this case the NC distance from A-Axis to the spindle was increased from 230 mm to 400 mm and additionally the spindle has 7 bearing points instead of 5, what is resulting in a positively longer live and a higher stability of the milling spindle.

SHW UniScan

3D Crash and Vibration overload recognition

SHW UniSc@n provides a real time crash recognition in all axes. This is possible with a 3D acceleration sensor with a reaction time of less than a millisecond. An identified collision leads straight to a machine stop, thus reducing significantly consequential damages. A further function provides warning limits with regard to vibration overload. Potential damages due to excessive use of the machine are prevented.

Machine diagnosis:

A further function of the SHW UniSc@n is a machine diagnosis which gives direct indications as to the condition of the machine. Consequently a condition-based maintenance is possible, thus avoiding unexpected downtimes and helping to achieve a higher machine uptime.


Security access standard version

Following the safety regulations, the rear machining area must be safeguarded by a security door.

By activating the key “Movement Start” / STOP” on the control panel and “Movement Stop” at the safety entrance, the machine can be stopped and the area behind the machine can be entered. After access to the operators platform the machine can be re-started via the key “Movement Start”. When leaving the area behind the machine through the safety door, the machine can be re-started via a key switch at the door “Movement Start”.


Sealing Air

As to all linear axes of machines, the glass scales are pressurized in order to reduce the residual risk of dirt and soiling to a minimum.

Where available, encoders of rotary- / turning tables also are supplied with sealing air.
