On round form tools, limited cutter projection should be achieved by restricting the
projection of the cutter beyond either:
● the round profile of the tool body
● or a ‘limiter’ (also called a deflector or counter knife) wh ich mirrors each cutter
Note: Limited cutter projection tooling should be used in addition to the normal
guards, protection appliances (jigs etc) and safe working practices, not as an
alternative.
7.1 Tool Setting
For safety reasons the cutterhead should whenever possible be mounted to run from
underneath the stock so that the stock will cover the cutterhead and shield your hands. Set
the cutterblock as low on the spindle arbor as possible. Always use cutters that are a
matched pair, and mount them directly opposite each other ensuring that they have the
same projection and are dynamically balanced. The majority of problems experienced on
spindle moulding machines arise from out of balance cutters, with the resulting bad feature
of excessive vibration, which tends to produce a poor finish on the article being machined.
Ensure that the correct number of spacers is used to effectively clamp the cutters.
7.2 Tool Handling
Care should be exercised when handling tools, wherever practicable use a tool carier or
wear protective gloves.
7.3 Tool Repair
Repair of tools should be carried out in accordance with the manufacturer’s instructio ns.
People who carry out repair of tools should be adequately trained and have knowledge of
the design requirements (eg BS EN 847-1: 1997) and levels of safety to be achieved.
