Work Table : This is mounted on the carriage and can be swiveled 45 degree on either side of the column. This table has a smooth and rapid movement longitudinally on the carriage through a roller chain guided and Supported on jibs. Slow movement is through a reduction gearbox. Change over from rapid to slow movement is through a push/pull knob. The precise movement on roller chain enables smooth, sensitive and accurate longitudinal movement even with heavy jobs.
