Vertical machining centre has fast axes
drives
A vertical machining centre equipped with linear motor driven axes drives has accelerations up to 2G to reach fast traverse speeds of up to 80m/min.
Introducing new levels of simultaneous five-axis precision contouring at the UK's MACH 2008 machine tool exhibition, DMG said its futuristic machine design can machine hardened steel, aluminium, copper and graphite The latest Deckel Maho HSC 55Vlinear, vertical machining centre has the added productivity enhancement of high speed, 80m/min linear drives and high speed 28,000 rev/min spindle technology

CNC miller-drillers cut 20% off machining times
With the highly productive DMU 50 / 70 eVolution, DMG has added a new dimension to universal milling and drilling machines designed to save up to 20% on machining times.
Based on a portal concept, the machine provides a large working volume of 450mm in X by 600mm in Y by 400mm in Z.
Developed using thermo-symmetric techniques, the HSC 55Vlinear has direct drive torque motors providing simultaneous swivel and rotary table movement of the 400mm square clamping surface unit with direct measuring systems to ensure the most accurate positioning and repeatability.
The A-axis will swivel between +10 deg and -110 deg.

Bar feeder has high capacity
SACO's new bar feeder reduces idle times and offers high precision and flexibility. Idle time for bar feeding to the collet is considerably reduced.
The C-axis is able to rotate at up to 120 rev/min with a maximum table loading of 200kg.
When in position, a fully integrated hydraulic clamping system is operated.
Through the advanced and well-proven linear drive systems, rapid traverse rates are 80m/min reached with an acceleration of 2G.
All drives and guideways are positioned on the outside of the working zone that provides a free fall and wash down of swarf into the machine base for extraction.
As standard, the 29kW, 25Nm torque HSK-A63 spindle will deliver 28,000 rev/min with a higher power option available giving 46kW and 80Nm with a top speed of 18,000 rev/min.
There is also a high speed 42,000 rev/min spindle available with a 13kW drive and HSK-E50 spindle nose.
Pneumatic balance is incorporated in the Z-axis.
The spindle is serviced by a 16 pocket tool magazine with optional 30 or 60 pockets available.
Chip-to-chip times for automatic tool changing are within 2.8s.
Laser tool measurement can also be supplied.
A pallet system is available to accept up to 20 workpieces for unmanned running with the automated loading system activated from the rear of the machine using the portal construction as a gateway into the working zone.
This configuration ensures unobstructed access to the spindle and surrounding area.
* Control system - control is DMG's ERGOline system with large and exceptionally clear 19in flat screen display.
This is combined with the DMG SlimLinePanel operating console enabling the operator to ergonomically adjust the position of the screen and keyboard according to his working preference.
DMG's SMARTkey is incorporated into the system that provides personalised authorisation to the operator that can include relevant access rights of individual preparation of the control.
Optional controls can be specified from Siemens with the 840D Solutionline or Heidenhain iTNC 530 incorporating 3D workpiece simulation.
Forming part of DMG's new branding through design concept, the DMC 55Vlinear incorporates state of the art scratch resistant brushed chrome surfaces and high gloss black finish on surface hardened plastic guarding.
This surrounds the safety glass panels that provide up to 40% improvement in visibility of the working area.
Also available is a fully integrated seating support for the operator that folds away under the control.
