DMG shows precise vertical machining
centres
DMG (UK) said that its precise vertical machining centres with linear motor powered axis drives offer excellent productivity, precision, contour precision and workpiece surface quality.
DMG has introduced its HSC 75 linear or HSC 105 linear vertical precision machining centres for larger workpiece dimensions Using linear drives in all axes, the machines are highly dynmic and offer excellent productivity, precision, contour precision and surface quality

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.
The HSC 75 linear and the HSC 105 linear offer in-line torque motor driven B-axis and the extension possibilities through to a continuous path 5-axis high-speed machining centre.
The linear drives in all axes of the two HSC machines generate accelerations up to 2G and rapid traverse speeds up to 90m/min, performances that are reflected in a productivity advantage of up to 20%.
The sturdy cast structure in gantry design and the FEM optimised high modulus machine bed form the basis for a perfect machine running behaviour and thereby highest surface qualities, said DMG.

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.
Direct path measuring systems allow unbeatable precision and contour precision.
The option of continuous path 5-axis machining uses the torque motor driven swivel axis in the milling head and the fast NC rotary indexing table.
The machines also offer an enlarged machining compartment, the optimal drop of swarf and the improved operator accessibility made possible by a modified bed geometry.
Furthermore, the lateral machine door and the front door release the roof to allow for loading by crane throughout the entire operating area.
* CNC systems - the vertical high-speed precision centres HSC 75 linear and HSC 105 linear use the DMG ERGOline-Control with high-speed 3D CNCs from Heidenhain (iTNC 530) or Siemens (Sinumerik 840D powerline).
The ergonomic control panel with 19in TFT screen and 3D software not only accommodates highest level 3D control technology, said DMG to manufacturingtalk, but also an innovative software tool named ATC (Application Tuning Cycle).
By pressing a key, it allows automatic selection of task-optimised machining parameters to be selected in the workpiece program, in accordance with the default values for surfaces, speed or precision.
* Optimising machining behaviour - instead of tackling each type of machining, such as roughing or high-speed finishing with fixed basic parameters of the machine, ATC automatically optimises the machining behaviour of the HSC linear machines in a workpiece optimising and targeted manner.
As a result, machining time is minimised, relevant quality is maximised.
The range of the HSC 75/105 linear is complemented by a large number of options, for instance, to increase the degree of automation.
Features of the HSC 75/105 linear VMCs are as follows.
* Linear drives in all axes for maximised precision and accelerations up to 2G to reach rapid traverse speeds of 90m/min.
* Continuous path 5-axis machining with direct drive in the spindle head and NC rotary indexing table (option).
* An 18,000 rev/min motor spindle as standard, optional 28,000 rev/min (HSK-A63) or 42,000 rpm (HSK-E50).
* DMG ERGOline Control with high-end control systems from Heidenhain or Siemens, including 3D software.
* Optimum use of space and accessibility to the machining compartment.
* Sturdy cast structure in gantry design and temperature compensation in the Z-axis as standard for maximum contour precision and surface quality.
* Weight dependent acceleration control and ATC software for simple finger-tip tuning of the linear advance drives (option).
