Ajax Machine Tools introduces four-machine AJG cylindrical grinding centre range

Ajax Machine Tools has introduced its AJG cylindrical grinding centres, offering four variants - AJG27, AJG30, AJG35 and AJG38.

The numeric designation signifies the maximum swing over the bed of from 270 to 380 mm, with the range able to process parts having 250, 280, 330, and 360 mm diameters, respectively, with a maximum loading capacity from 60 to 150 kg.

Centre distances for the AJG27 are 350, 550 or 750, while the AJG30, AJG35 and AJG38 accommodate part lengths up to 1,000 mm, 550/750 mm and 1,000 mm, respectively.

The wheelhead on the AJG Series is capable of swinging ±15° to the right and left, while in-feed travel is 250 mm. The latter can be controlled automatically or via handwheels. An automatic in-feed increment of 0.001-1.8 mm and a handwheel movement per division of 0.005 mm feature.

A 3.75 or 5.6 kW motor provides a grinding spindle speed of 1,650, 1,850 or 2,100 rpm for 405 mm diameter wheels that can be 32-50 mm wide on the smaller AJG27 and AJG30 machines, with 38-75 mm possible for the larger AJG35 and AJG38 cylindrical grinders.

For the machine table, a swivelling angle of 6/9° and a variable traverse speed of from 50 to 4,000 mm/min operate.
