Two new machining centres, including the EMC mini vertical from Fadal and the compact Kiwa KNH-426 horizontal cell, will be introduced by Yamazen (UK) at MACH 2002.

Two new machining centres, including the EMC mini vertical from Fadal and the compact Kiwa KNH-426 horizontal cell, will be introduced by Yamazen (UK) at MACH 2002.

Also on display on Stand 4618 in Hall 4 will be the Samsung PL25A CNC lathe and the Mitsubishi M-H5B horizontal machining centre.

Yamazen hopes to give a European debut to the Fadal EMC mini vertical machining centre - the latest model introduced by this leading US builder.

Requiring a floor area of only 1.9 by 1.95m, this compact machine can fit into small spaces yet it provides a high level of metal cutting performance compared to other mini models on the market.

With a working envelope of 508 x 406 x 355mm, the EMC is powered by a 12hp motor, offers spindle speeds up to 7500rev/min, has a 16-station ATC and axis positioning to +/-0.005mm.

The 749 by 406mm worktable can handle parts weighing up to 454kg.

A range of optional extras is available including: rigid tapping, digitising package, fourth rotary CNC axis, tool load compensation and tool breakage detection.

Another new to the UK machine being exhibited by Yamazen is the Kiwa KNH-426 high speed horizontal.

This Japanese-built 400mm2 pallet machine is being supplied as standard in the UK with a 20,000rev/min spindle, six-station pallet pool, 120-station ATC, advanced spindle core cooling system and a special mechanical tool locking arrangement.

Combined with rapid traverse rates of 60m/min and an affordable price tag, the Kiwa stands out from other horizontals in its class.

Power is from a 22kW motor and this compact machine has a working envelope of 600 x 610 x 665mm while each of the six pallets can handle a maximum load of 400kg.

Control is from a Fanuc 18i-M system.

Moving on to CNC turning, Yamazen is also showing the PL25A - the latest model in the Samsung range of CNC lathes.

Designed for heavy-duty cutting, the machine combines rigidity and power along with anti-vibration and anti-backlash mechanisms for high accuracy machining.

The slant bed PL25A is available in two model variants - 500 and 1000.

Both have a 520mm swing over the bed, an 11/15kW motor, a 10-station turret (as standard), a top speed of 3500rev/min and a maximum machining diameter of 350mm.

The PL25A/500 has a distance between centres of 625mm and can machine parts up to 530mm long while corresponding figures for the PL25A/1000 are 1125 and 1030mm.

Two-axis control is by way of either Fanuc or Samsung CNC systems.

Completing the stand line-up is the Mitsubishi M-H5B high-speed horizontal machining centre.

With axis travels of 650 x 650 x 650mm, this twin 500mm2 pallet machine has a spindle speed of 12,000rev/min spindle, rapid traverses of 40m/min, a 60-station ATC, a Fanuc 18i M control and is powered by a built-in 22kW AC spindle motor.

Tool and pallet changing times are 1.3 and 5s, respectively.

This model can also be equipped with Fine Mould (FM) software for the high speed and high definition machining of moulds and dies.

This system provides a number of features designed to minimise machining errors, direction changeover inaccuracies and vibration problems.
