Among 10 machining centres, CNC lathes and a VTL to be shown at MACH 2004, will be a large spindle bore CNC lathe, turning centres and a CNC VTL with a 17kW driven tool facility.
With a total of 10 machines being displayed - including three new models from Kia (the 1 m plus capacity VX500 vertical machining centre), Toshulin (the cost-competitive SKL12 vertical boring and turning machine) and Soraluce (the high-performance SP-8000 travelling column, fixed-bed mill, which is also likely to be the biggest machine at the show), Ward CNC's 500m2 display in Hall 4, the largest stand at MACH, will certainly emphasise that both 'big and small machines are beautiful'. With a variety of the machines either under power or cutting metal, the Ward CNC display will also include representatives of the company's Union (boring and milling) and Hankook (turning) ranges, so clearly the Sheffield-based machine tool specialist will be presenting something for everyone at the NEC. Included in the 11 machine tools on show, and being demonstrated, are the following CNC lathes and vertical turning lathe (VTL): * Toshulin SKL12 VTL.
a.
Three Kia turning centres - SKT21LMSB with driven tools and sub-spindle, SKT15LM universal with driven tools, and the SKT300 heavy-duty with geared head and solid slideways.
* Hankook 9NC large spindle bore CNC lathe with front and rear chucks and 4000mm between centres.
Visitors to the stand will be spoilt for turning centre choice, with three models on view.
Complete with a C axis, live tooling, sub-spindle and a 65mm spindle bore, the Super Kia Turn 21LMSB is a machine that Ward CNC managing director Simon Whitworth describes as 'world beating' for maximising value-for-money productivity on bar work up to 65mm.
The main 15/11kW spindle motor produces 25 to 4,000 revs/min, while the 3.7/2.2kW sub-spindle reaches 30 to 6,000 revs/min.
The 12-station bi-directional turret has a driven tool speed range of 20 to 4,000 revs/min generated by a 3.7/2.2kW motor.
With an X axis (cross) travel of 220mm and a Z axis (longitudinal) travel of 550mm, the machine has a maximum swing over the bed of 550mm and a distance between centres of 530mm.
Rapid traverse rates are 36m/min.
The Super Kia Turn SKT300 has a maximum turning diameter of 560mm, a maximum turning length of 720mm and a 90mm diameter bar capacity/305mm diameter chuck.
Travels in X and Z axes are 355mm and 750mm and the spindle provides 3,000 revs/min.
Feed rates 20m/min and 24m/min in X and Z, respectively.
With a 12-tool turret and two-stepped geared headstock designed for high-torque, heavy cutting, and programmable tailstock, the Fanuc-controlled SKT300 is designed to minimise non-cutting times while consistently producing parts to 3.5 micron accuracies (in brass, for example).
Completing the Kia display will be the Super Turn 15LM universal three-axis turning centre with driven tools and C axis, having a maximum swing of 550mm and turning diameter of 255mm.
Distance between centres on this 43mm bar capacity machine is 530mm.
Spindle speeds reach 6,000 revs/min, and rapid traverse rate in both the 220mm X and 550mm Z axes is 36m/min.
New from Toshulin is the SKL12 VTL, which can turn and face workpiece diameters up to 1700mm, and has a Z axis capacity of 1200mm and a ram stroke of 1000mm.
With a 1250mm diameter table having a speed range up to 500 revs/min, and an up to 10 revs/min C axis, the 17kW machine's driven tool spindle has an infinitely variable speed range up to 3,000 revs/min, complemented by working travels and rapid traverse rates of 1-4000mm/min and 3000mm/min, respectively.
Typifying the high quality of build and cost-and-performance specification available from Hankook, the Protec 9NC lathe is based on a double-walled and ribbed one-piece meehanite cast iron bed with induction hardened and ground precision slideways for maximum stability and accuracy.
The large spindle bore (up to 440mm) 9NC has a 950mm swing over the bed, 630mm over the carriage and 4000mm between centres.
With Fanuc CNC, the machine boasts spindle speeds of 2 to 1,000/3 to 440 revs/min.
Marposs Mida Laser 105 laser toolsetting and an E86 radio transmission spindle probe will also be evident on the Ward CNC stand.
