INSTALLATION INTRODUCTION Clausing-Colchester lathes are the result of half a century of concentration in manufacture of this type of machine tool. Whilst essentially precision tools intended for producing accurate workpieces, the design of robust construction and simplified controls makes these machines suitable for tooling in production work. All castings are naturally aged for at least six months to avoid possible distortion. Jigs and special-purpose machines are used extensively in our manufacturing operatjons to ensure interchangeability of compon- ents. Care is taken in all processes of all departments to ensure your satisfaction with the machine.
The headstock is an all-geared arrangement, totally enclosed within an oilbath and giving sixteen spindle speeds. The main spindle is precision finished from a heat-treated high tensile steel forging and is carried at the front end on Gamet high precision tlouble row taper roller bearings of exceptional accuracy which are specially manufactured to our requirements. The rear end of the spindle is carried in a single-row taper roller bearing of similar design. All headstock spindles and shafts are carried-in needle roller anti-friction bearings.
LIFTII{G The complete machine weighs approximately 2,300 lb and proper equipment must, therefore, be made available for handling this weight, All lifting and repositioning should be carried out with great care, It is recommended that a lifting bolt with clamp plates to the dimensions shown on the sketch should be used. Wind the saddle and slides towards the tail end of the lathe and fit the clamp plate securely at the point of balance of the machine. Do not sling the machine from any other points. In case of difficulty, consult your local Clausing-Col- chester agent.
INSTALLING In order to achieve the full standards of accuracy built in to your Clausing-Colchester lathe, it is essen- tial that the machine be installed upon a solid con- crete base which must be as level and free from vibration as possible. For most applications the machine will then perform perfectly satisfactorily whilst free-standing. Six mounting points are built into the cabinet base, and these will give all the sup- port needed by the machine. lf there are objections to having a f ree standing machine, bolts may be used, providing ihey are not overtightened. When operating at high speed on out-of-balance work, it may become necessary to bolt the machine to the concrete foundation.
WORKING AREA When deciding upon the position for the lathe, remember that sufficient room must be allowed not only for ease of operation but to permit the end guard to be opened, for access to the motor compartment at the rear of the cabinet base and for the servicing operations recommended. A foundation plan is included which gives the main installation dimensions and also the recommended minimum space required for efficient operation of the machine under aU conditions of working. Careful attention to siting and foundation will greatly add to the accuracy of the work produced and to th6 life of the machine.
lf the lathe must be installed above ground floor level, it is essential for best results to provide a concrete floor and to position the machine headstock as close as possible to a supporting wall or pillar. Wooden floors are not recommended be- cause changes in atmospheric conditions which affect the floor will adversely affect the alignment of the machine. When woodenfloorsiting is unavoidable, a section of the floor should be taken up and a con- crete base built up to the floor level. CLEANING Each lathe is delivered having all bright machined surfaces covered with a heavy protective coating.
Before attempting to operate the machine remove all traces of the preservative using white spirit or Kerosene. It is not recommended that the machine is placed on felt or rubber mats no matter what type of foundation is provided. DO NOT USE CELLULOSE SOLVENTS FOR CLEANING_THESE WILL DAMAGE THE PAINT FINISH. When cleaning, pay particular attention to the dlides and spindle nose. lt is essential that the end guard be removed and the gear train carefully cleaned before operating the lathe. All cleaned parts should then be dried using fluff-free THts MACHINE SHOULD NOT BE GROUTED IN,
