Basic Points on Moulding Machines
Moulding machines are used for cutting profiles in lengths of material. Also referred to as spindle moulders and spindle shapers, they differ from router tables in that they typically are more powerful and run at a lower speed. This is necessary when using very large moulding cutters, and it also gives these machines much power than a router.
A common question is whether or not a moulding machine can replace the need for a router table, since most spindle moulders have optional router collets. In general, the disadvantage of doing this is that router bits are designed to run at relatively high RPM (around 12,000-14,000 for large profile bits and 20-25,000 for smaller trimming bits). Running these sorts of bits on a moulding machine that runs at less than 5,000rpm means that the bit will be running at a much less than optimal speed and typically the finished result will be less than ideal. Moulding machines are designed specifically for use with large profile cutterheads and their lower RPM reflects this.
An alternative for smaller work is our dual-purpose planer moulder. It uses a section of its planer cutterhead to hold specially designed profile cutting knives. |
