Ward Principals To Show World-Class Machining Capabilities At Milan EMO

Ward CNC principals Hankook, Hartford, Hyundai-Kia, Soraluce and Union will all be present at the Milan EMO (October 5-10) promoting examples from their world-class ranges of machine tools – presenting the extraordinary specifications available at unrivalled price tags.

Hankook's display will focus on the VTB-160E ram-type vertical boring and turning machine that has maximum turning diameter and height of 2,000 mm 1,400 mm, respectively, a vertical travel of cross rail of 750 mm, and a table of 1,600 mm diameter capable of 0.7 to 280 revs/min.

Hartford will have several vertical machining centres on view, such as the 5VM-60RT five-axis moving column model, the HEP-3150AP double column, the HCMC-15AG and PRO-1000 AP open-fronted units, and the MVP-10AP plug-and-play machine.

The construction of the Power Centre Pro-1000 is, like its Hartford stablemates, based on a cast iron frame with hardened and ground box slideways. The machine has a table of 1,150 mm by 600 mm capable of accommodating workpieces weighing 700 kgs, and X, Y and Z travels of 1,000 mm by 600 mm by 510/630 mm.

As standard, rapid traverse rate in all axes is 20 m/min, the 7.5/10 kW spindle produces speeds of 40 to 8,000 revs/min (pulley-style – 6,000 revs/min geared) and the machine is supplied with a 20- (optional 24) tool automatic toolchanger.

With Hartrol-Fanuc AI100/0iMC CNC, a major feature of the control technology is the Hartrol advanced functionality programming routines available as standard; a series of easy-to-use cycles designed to simplify and speed up programming times and therefore reduce downtime along with other useful setting and maintenance functions for ease of operator use.

The routines embrace, for example, workpiece datum setting using edge setter, manual tool setting using calibrated setting block, tool magazine tracking (for arm-type ATC), tool logging and spindle load monitor, as well as full M Code listings and a comprehensive set of special canned cycles.

An impressive batch of nine Hyundai-Kia machines will be displayed; the SKT700LM turning centre, KH1000 and HS500 horizontal machining centres, SKT-V80RM vertical turning/milling machine, SKT180TTSY multi-tasking twin-spindle turning centre, Hi-V560M/5A vertical machining centre, SKT2100SY Y axis multi-tasking turning centre, SKT2500MTS multi-tasking mill/turn centre and the SKT-F160/2SP twin-spindle turning centre.

p>Looking at the Hyundai-Kia SKT MTS Multi-Tasking Centre, visitors to the EMO stand will immediately realise that highly productive, highly flexible and very cost-effective single set-up mill/turn applications are on offer with this four-axis unit.

In particular, a major benefit on the SKT 2500 MTS is its 18.5 kW, 8,000 revs/min, high-torque B-axis milling head and the 4,500 revs/min sub-spindle with full C axis capability (that complements the 30 kW main spindle) which, with ‘kissing spindle' design, enables synchronised part exchange at 30 m/min rapid traverse.

Indeed, the machine's credentials for flexibility are based around the milling head that has + 1200 rotation with 0.0010 indexing through a heavy duty, dual-lead worm gear and servo motor. The head has the added advantage of 250 mm Y-axis stroke for off-centre feature machining and a Z-axis stroke of 1,100 mm servicing both main and sub- spindles.

The milling head slide (which also accommodates standard lathe tooling) also carries a 22-tool magazine (optionally, 43 or 65) that provides a tool change time of just 1.5 secs and chip-to-chip time of 5 secs. The maximum tool size is 95 mm diameter which can be extended to 104 mm when adjacent pockets are empty.

With a bar capacity of 76 mm, a 10 inch chuck size and options of programmable tailstock, the SKT MTS has a maximum turning diameter and length of 500 mm and 1,100 mm, respectively, while the swing over the bed is 780 mm. Fanuc 18i-TB is the control system.

The machine combines high power in a heavy-duty single cast bed construction with rigid box guideways, and if the optional, fully programmable 110 mm diameter quill tailstock is specified, automatic clamp and unclamp is incorporated.

Soraluce will have trio of machines on view - just a small representation of the company's comprehensive range of travelling table, travelling column bed-type and travelling column floor-type machines – the FX-R-20000 floor-type, the SP-10000 fixed table, travelling column model and the bed-type TA-25-A.

With a vertical (Y axis) stroke of 6,500 mm, a cross travel (Z axis) of 1,900 mm and a longitudinal traverse (X axis) of 20,000 mm, the FX-R-20000's 3,000 mm by 3,000 mm table can accommodate 40-tonnes workpieces. The machine has feed and rapid traverse rates in X, Y and Z axes of 10-10,000 mm/min and 20,000 mm/min, respectively.

The machine's ‘multi-purpose single set-up' heavy machining through to high-quality surface finishing tagline is endorsed by its 120-tool ATC, and the use of the automatically-interchangeable 37 kW, 4,000 revs/min orthogonal head, that can position in 1deg by 1deg increments, complementing the 46 kW, 2,500 revs/min, 37 kW fixed boring head that can position in 2.5deg increments, and the 4,000 revs/min fixed horizontal head as well as a wide range of optional CNC tables. Control is by Heidenhain iTNC 530.

Union, meanwhile, will be promoting the new PR 200/250 – a cost-effective boring mill purposely designed for simultaneous rough and ultra-precision finish machining of large workpieces – up to 8 m high and weighing 250 tonnes - and equipped with a spindle diameter of 250 mm, and a main drive motor rated at 130 kW that produces torque up to 17.000 Nm. Rapid feed rates are up to 25 m/min.

The ability to combine roughing and finishing is made possible by the use of hydrostatic guideways in the main X,Y and Z axes. Hydrostatic guideways utilise a permanent oil-film between guideway surfaces to eliminate mechanical wear. They also permit high chip removal rates due to the resulting extremely high damping effects.
