Mill-turning centre has horizontal/vertical axis
Mill-turning centre has three distinct modules all in one machine; a turning unit with horizontal axis, a turning unit with vertical axis and a multi-purpose head with a swivelling B axis.
Machine tool service has to be memorable
"Providing a memorable service experience is crucial to customer satisfaction and the development of long term relationships," says Paul Lee, Managing Director, CNC Machine Tools.
These vertical machining centres feature a moving column design enabling maximum rigidity and maximum reliability.
The MV4 machine is equipped with a 12,000 rpm (ISO 40) or 24,000 rpm (HSK 63) spindle.
The spindle power can reach 18.5kW from 1,500 rpm.

Long X-axis VMC allows pendular machining cycles
Designed to allow a non-stop manufacturing system that eliminates idle time, a VMC with a long X-axis, is equipped with a partition, which allows pendular machining.
High speed machining VMC maximises productivity
High chip removal, high speed machining and quick set up and change over times of a 1.8m X-axis VMC give maximum productivity and at the same time deliver very high machining accuracy.
The machine can also accept an ultra high speed 32,000 rpm spindle (HSK-E40) with special ceramic bearings.
The automatic tool change, provided by a double arm and a random selection, has 20 (or optionally 36) locations storage.
A centralized coolant device is fitted as standard supplied by an automatic pump.
A secondary coolant pump ensures swarf is kept clear of the working area.
Through spindle coolant is also available as an optional specification.
The machine is designed to allow a non-stop manufacturing system that eliminates idle time.
The machine is equipped with a partition, which allows pendular machining.
Loading of one side can be made during the production cycle of the other side of the machine.
Eliminating these loading/unloading idle times provides the user with maximum productivity, both in the machining of medium-large sized batches and in the machining of different families of workpieces in single batches and of small sizes.
Another benefit is the outstanding longitudinal X axis travel values.
The full X axis on the MV series machines have a usable work surface from 1500 up to 2000mm.
in length making them ideal for longer workpieces without comparable increases in Y and Z axes.
The latest computer aided technology has produced a machine frame, which guarantees stability and rigidity even under heavy working conditions.
The x-y-z feed is obtained by brushless AC servo motors connected with high precision ball screws.
For the X axis, the machine has a rotary nut screw, which increases rigidity over the longer travel ranges.
For highest efficiency, the MV 3 and MV4 sized machines can be built with a twin spindle configuration (DS series), which gives double the output compared to the standard machine.
This also features a double toolchange system with 2 x 20 (optional 36) tool positions.
The MV series can also be supplied with a wide range of CNC systems: Fanuc, Siemens and Heidenhain which enables it to be adapted to real working conditions depending on the end user's requirements.
