A Large Surface Grinder
The photograph we reproduce below shows a new twin-head horizontal surface grinder, which has been installed at the Birmingham works of British Timken, Ltd., for use on railway axle housing production.
This machine, which was designed and constructed by the Thompson Grinder Company, of the United States, is claimed to be the largest of its kind yet built. It is about 35 ft. long, 16 ft. wide and 12 ft. high. The hydraulically operated table is powered by a 30 h.p. pump and motor and has a working area 10 ft. long by 6 ft., wide.
Work up to 8 ft. 4 in. wide can be admitted between the columns. Each of the two, wheel heads is powered by a 30 h.p. motor and carries a 24 in. diameter, 5 in. wide periphery grinding wheel.
The machine has operating equipment of the most recent design, employing push button control, electronic timing control and solenoid-operated valves in the hydraulic system. Dual control is fitted and one operator can control all movements from each side of the machine. |
