TAILSTOCK Back to Index TAILSTOCK The Tailstock is of rigid design with a large diameter spindle and screw, and is mounted on independent vee and flat surfaces on the bed. The hole in which the spindle slides is honed to very close limits of accuracy. The spindle, bored No. 3 Morse Taper, is graduated in inches of travel and is locked in position by a hand lever. Provision is made for the ejection of centers when the spindle is wound right back, and set screws are fitted to enable the tailstock to be set over for taper turning. A zero setting line simplifies resetting. Rapid locking of the tailstock to the bed is by means of a detachable ring spanner.
THE MOTOR DRIVE The motor drive is totally enclosed within the cabinet base and therefore avoids all possibility of motor failure due to chips or coolant splash. The drive is taken to the main drive pulley on the headstock by two 1/2" vee belts enclosed in a light alloy end guard. In order to avoid electrical shocks when adjustments are required to be made to the switch panel, it has been arranged so that the removal of this will completely isolate the supply. To prevent unauthorized use of the machine the locking of the cabinet drawer will also isolate the motor and starting gear controls. The standard motor is a If H.P. 2-Phase or 3-Phase, but D.C.
and Single Phase motors are fitted to order at extra cost, the additional cost being dependent on the type of motor and starting equipment required. Provision for motor belt adjustment is provided by a swinging platform clamped with two bolts which is accessible when the back cover of the cabinet is removed. COOLANT UNIT Feed Box Drive The cabinet base has been designed so as to house the coolant pump and supply. This is situated in the center of the cabinet and is easily accessible by a door at the front of the machine for cleaning, filling and attention to the pump. There is provision in the chip tray for a return of the coolant through a filter gauze to the supply source.
The pump and coolant unit is furnished to order only at extra cost. The Coolant piping supplied is fully universal, with telescopic piping for feeding the coolant in any position. Spring loaded glands are employed which require no adjustment. A patented ball type shut-off valve permits easy control of the volume of coolant. The whole unit is designed to eliminate the leakages which are usually associated with coolant systems. The Clausing-Colchester unit has a capacity of 5 1/2 gallons. 11
