Horizontal machining centre is very accurate
Highly accurate and productive HMC offers effective chip removal, reduced non-cutting times, fast acceleration and deceleration, oil-cooled ballscrews and straightforward maintenance routines.
Accurate HMC has fast acceleration
Key features of a highly accurate HMC include: effective chip removal, reduced non-cutting times, fast acceleration and deceleration and more straightforward maintenance routines.
Available from Yamazen (UK), this latest HMC features effective chip removal, reduced non-cutting times, fast acceleration and deceleration, oil-cooled ballscrews and is competitively priced.
With a working envelope of 700 (X) by 700 (Y) by 650mm (Z axis), the DCH50 is powered by a 22/15kW main motor which provides spindle speeds up to 14,000 rev/min as standard.
Rapid traverses are rated at 50m/min in all three linear axes and the 60-station capacity ATC (automatic tool changer) has a tool change time of 3.2 sec chip-to-chip and can accommodate tools weighing up to 8kg each.

VMC mini mill does more than drill and tap
While many machines on the market described as 'mini mills' are just mill/tap centres, a subcontractor says that its 'mini-mill' is a powerful three axis vertical machining centre.
Compact VMC offered at affordable UK price
A 'mini-mill' vertical machining centre offers small footprint (1850 x 1850mm), large capacity (610 x 305 x 460mm) and affordable price in the UK (at just GBP 24,950).
Feed rates up to 10m/min can be specified for all the main axes.
The full fourth axis CNC table can index 90 degree in 1.2 sec while the twin 500 by 500mm pallets can be exchanged in 6 sec by the APC system and handle loads up to 500kg.
Control is from a Fanuc 18iMB system and the machine has a positioning accuracy of +/-0.002mm/full length with a repeatability of +/-0.001 mm.
This level of precision is due to the use of MP scales on all three linear axes combined with a thermal displacement compensation system.
Equipped with a BBT40 (Big-Plus) dual contact type spindle, the DCH50 has been designed for high productivity, ease of operation and improved chip removal.
It also has three point levelling (for ease of installation and accuracy) and occupies a floor area of just 4.15 by 4.31m.
Productivity has been optimised by way of reduced non-cutting times and faster movements - the spindle reaches its top speed in just 1.8 sec and both X and Y axes accelerate/decelerate at 1G.
While rigid tapping can be performed at some 4000 rev/min.
On the swarf handling front, the machine features a stainless steel centre trough, double internal coil conveyor and coolant flushes for the ATC arm, APC set-up station as well as the general machining area.
In order to maintain high accuracy during machining, the Mitsubishi utilises systems for both isolation and cooling to compensate for primary heat-generating sources.
Optional equipment available includes: auto tool length measurement, air dryer, auto workpiece measuring (using a touch probe) and a mist collector.
