The DMC 635 V eco vertical machining centre features an 8,000rev/min spindle with 82Nm torque, a 20-pocket SK 40 tool magazine with double gripper for short changeover times of only 1.6 seconds, and dynamic-axis drives of up to 25m/min.

It has a working volume of 635 x 510 x 460mm.

The machine is based on a sturdy, cast-iron C-frame that is effective at dissipating energy and dampening unwanted mechanical vibrations.

The table helps to provide rigidity and precision, which are further promoted by roller guideways in all axes and three-point machine support.

The latter also shortens and simplifies initial start-up.

Touch probing of workpiece and tools, an NC dividing head as a fourth axis, and CAT 40 or BT 40 spindles can all be specified.

In addition, DMG offers two option packages.

The chip-disposal package includes a chip conveyor, cleaning spray gun and a four-colour indicator lamp for higher production environments.

The precision package includes Z-axis thermal compensation, linear-scale positional feedback in all axes and a Blum laser for integrated tool measuring.

Control is provided by a Heidenhain TNC 620 digital drive CNC system with shop-floor-oriented programming capability and visual simulation of workpiece machining on the 15in (381mm) screen.

Features include free contour programming and measuring cycles for workpiece alignment.

The 100BaseT Ethernet interface can quickly download externally prepared programs.

The control offers special functions, such as dynamic look-ahead, and algorithms for jerk limitation and intelligent motion control, designed to produce optimal five-axis machining results.

It also has DMG’s Smartkey built in, which offers a wide range of options, such as personalised user authorisation with customisable access rights and individualised preparation of the control.

The DMU-P Series of machining centres provides high productivity rates, top precision and superior surface quality and contour accuracy of the machined workpiece.

The latest addition is the DMU80P Duoblock five-sided/five-axis model, which provides 800mm of travel in X, Y and Z.

An impressive 0.6G acceleration to 60m/min rapid traverse in all axes and short chip-to-chip times of up to 4.5 seconds between tools ensures short idle times and high productivity.

The thermo-symmetrical design is based on the Duoblock concept, which consists of two sturdy cast-iron blocks, three guideways in the X-axis for stability and three-point support of the machine bed, which allows fast commissioning.

The moving mass has been reduced to optimise dynamic response.

Fourth and fifth axes are provided by a B-axis on the spindle head and a rotary table.

There are various motor spindle options, one of which is the 5X Torquemaster, which provides simultaneous five-axis machining at high torques up to 1,100Nm.

The DMU80P has been designed for minimum lubrication and is eminently suited to dry machining.

The DMU50 vertical-spindle, fully interpolative five-axis machining centre has a small footprint, despite the X/Y/Z travels of 500/450/400mm.

The Ergoline control is equivalent to the CNC systems driving higher-end equipment and build quality.

This means full five-axis technology at the quality end of the market can now be accessed by a much wider customer base across the general engineering sector.

The fourth and fifth axes are provided by a 360-degree rotary table carried on a vertically-mounted unit that swivels from -5 to +110 degrees, enabling undercuts up to 20 degrees to be machined.

Linear speed is up to 24m/min in all axes with 5m/s2 acceleration.

Recirculating ballscrews in the linear-axes transmit the feed force via robust bearings and components.

DMG’s wide linear roller guideways feature low heat production, minimal friction, no stick-slip and low wear.

Linear scales are available as an option to rotary encoders for positional feedback.

The 9/13kW (100 / 40 per cent DC) motor-spindle is driven up to 10,000rev/min directly by a digitally controlled, three-phase motor.

Alternative spindles are either 14,000rev/min or 18,000rev/min, the latter rated at 25/35kW (100/40 per cent DC) with a torque up to 130Nm.
