Locating The Machine
The machine must be installed and suitably positioned on well-prepared foundations in order to ensure
reliable operation and high accuracy. It is important that the area is well lit, as dry as possible and free from
vibration. It should be located so that adequate space is provided for utilisation of maximum ranges together with
maintenance. It is recommended that 28 inches clearance be provided at the ends and rear of the machine, with at
least 40 inches at the front for the operator.
General Dimension
Foundation
A substantial concrete foundation is recommended for this machine. If it is located on a wooden floor,
ensure that it is adequately supported and free from vibration. If it is to be located on an upper floor, position it
directly over a supporting beam or girder to reduce any vibration generated from nearby machinery.
Levelling The Machine
Use a precision level graduated to at least 0.001 inch per foot. The levelling procedure is carried out two
stages. The first being the preliminary levelling and the second the final levelling. The preliminary levelling is to
remove any pronounced twist in the bed and adjust the screws under the
headstock until the reading is zero. Move the level to the tailstock and adjust
the screws until the reading is zero. Re-check and carry out any minor
adjustments necessary with the level at each of the above positions.
For final levelling, place the level lengthways on the front flat way, close the
headstock end and adjust the screws under the headstock end leg until the
reading is zero, at the same time, check with the level across the top of the
Bedways to ensure that these adjustments do not cause a twist in the bed.
Place the level lengthways on the front flat way close to the tailstock and
repeat the operations above. Also, check with the level across the vee ways to
eliminate any twist.
Repeat the operations and make whatever minor adjustments are required.
The next procedure is to level the machine cross ways by placing the level
across the carriage wings and moving the carriage from one end of the bed to
the other without disturbing the position of the level. If the level shows any variation throughout its travel, the
screws nearest the point where the variation occurs should be rested or lowered to bring back to zero.
