Ajax Fusion lathes provide a one-off or automatic repeat batch production solution

The smallest capacity machine, the Ajax Fusion AJF 180, has a swing over bed of 360 mm and options of 750 or 1,000 mm between centres. The machine's four-way automatic indexing tool post can optionally be upgraded to an automatic eight-station turret. A 'teach and repeat' facility provided by the Fagor 8055TC control, employs electronic hand wheels and interactive colour screen graphics. As a result, the machine has a fast program build-up capability for a simple turning operation, while a more complex part can be programmed by following step-by-step, drawing-based moves. The machining toolpath is also displayed through dynamic graphics simulation giving full-in-cycle verification. Among the array of canned cycles available are simple turning, multi-point profiling, grooving, drilling, taper turning and screw cutting with the control even accommodating process elements such as roughing out, finishing and thread repair. Offline data can be fed through an RS 232 communications port, USB or RJ45 network interface, so full ISO programming can also be used. The four Ajax Fusion machines span a swing over bed capacity between 360 and 620 mm with between centre distances up to 3,000 mm. The heavy duty cast beds have hardened slideways to 400-450 HB and weigh between 1.5 tonnes for the AJF 180 and 3.6 tonnes on the largest AJF 310 machine. Spindle powers across the range from 7.5 to 15 kW. The Ajax Fusion AJF 180 has a 7.5 kW spindle motor with a 4,000 rpm maximum speed. The main spindle bore size is 42 mm. Feedrates to the carriage are up to 7,000 mm/min with a rapid traverse of 10 m/min. There are two, three-jaw self-centring 160 and 200 mm chucks available and a standard four-jaw 250 mm independent chuck. The tailstock has a barrel diameter of 58 mm and travel of 180 mm. A high power coolant system, automatic lubrication and low voltage flood lighting are included. The machines' full surround guarding with slide aside doors gives full access. Options include fixed and travelling steadies, BOB CAD DNC Windows communication software and an off-line programming system. A range of toolholding equipment is also available through Ajax Machine Tools International to suit the universal operation of the machine.
