7. Direction of rotation
It is most important that the tooling is fitted to the machine to operate in the correct direction of rotation.
The operator shall ensure that the workpiece is fed to the tools against the direction of spindle rotation.
7a. Speed selection
The operator must ensure that the correct rotational speed has been selected and is appropriate for the tooling
being used on the machine.
8. Machine operation, guard selection and adjustment
Because of the wide variety of work which van be undertaken on vertical spindle molding machines using
different types of top spindles, cutter blocks and cutters, no one type of safeguard can be considered effective
for all conditions. Each operation should be considered separately and the best practicable safeguard selected
for that particular job. Also, the type of cutter block, the cutter projection and the height at which the block is
set, will determine the minimum size of the hole in the table. This can be obtained by using the loose rings
provided so as to give the smallest possible hole, thus reducing the risk of the workpiece dipping and catching
the edge as it passes over the gap.
Guarding shall enclose the cutters to the greatest extent permitted by the nature of the operation.
A power feed unit fitted to a vertical spindle molding machine with a straight fence can have the effect of
enclosing the cutters to the greatest extent practicable and often represents the best method of guarding on
these machines. Such feed units shall be easily adjustable to suit different sizes of workpieces and should not
in themselves create a trapping hazard.
If a power feed is not used, pressure pads with the table and fence spring loaded pressures forming a tunnel
through which the workpiece can be fed shall be used in conjunction with a false fence or other means of
closing the gap between fences.
9. Straight work where the molding extends over the full length of the workpiece
Work of this type is done with the aid of a straight fence and, in most cases; the workpieces are of regular
rectangular section throughout their length. The workpieces, can, therefore, be guided in the angle formed by
the table and the fence. Vertical and horizontal spring loads pressure pads van be arranged to form a tunnel
through which the workpiece can be fed. A following piece can be used to feed the previous one, with the
final piece being completed by using a push stick. When machining thin panels the top spring pressure pad
only may be necessary, providing its width is adequate.
Specialized shoes shall be used according to the workpiece dimension.
1-13 On a vertical spindle molding machine the gap between the two halves of the straight fence has to be
