AJSGTC 2000 - Surface Grinder
There are many models of Ajax Surface Grinding Machines with working areas up to 3200 x 850mm.
All machines are traditional in design with easy access for complete, accurate and efficient control. All models are suitable for toolroom and production work. The longitudinal table movement is hydraulically driven and the cross traverse and wheel head feeds are electrically driven, all with infinitely variable speed control.
All models are available with manual downfeed of the wheel head and/or automatic downfeed which can be incrementally pre-set. Machines with the H suffix indicate automatic longitudinal and cross feed as standard. Suffix HD indicates that machines are also equipped with automatic downfeed.
The Wheel Head
The wheel head spindle on all models is mounted on super precision bearings, completely sealed and maintenance free. The casting is constructed for extreme rigidity of the spindle and bearing assemblies. The grinding spindle is directly coupled to a dynamically balanced, flange-mounted motor through a shock absorbing coupling. The wheel head of all HD models is provided with rapid power positioning with fine positioning carried out by means of a 0.0025mm incremented handwheel.
The longitudinal movement of the table is provided hydraulically and the rate of traverse is infinitely variable between the ranges shown below.
Lubrication of all slideways is by means of an electronically controlled pump unit through metering valves to the various lubrication ports. Hand traverse of the work table is by means of a hand wheel rack and pinion. The table is provided with ample operator splash protection.
