Bearing guided cutters
F
• The arrow shows the direction of the feed for routing a profile on the edge of a piece of material using a bearing guided cutter.
• Material should be securely clamped or placed on a non-slip mat.
• The bearing will follow the profile of the edge of the material.
Department of Manufacturing & Operations Engineering
WT4603
Bearing guided cutters
• When viewed from above the feed direction for processing a moulding on the outside of a component will be in an anti-clockwise direction.
• Care needs to be taken when rolling around the corners or coming to the end of a straight as the router plate may not have as much support from the material underneath.
Department of Manufacturing & Operations Engineering
WT4603
Feed direction• Feed direction is critical to the
machining process.• The cutter rotation will be in a
clockwise direction.• To establish the correct feed
direction use the right hand rule shown in the photo.
• Place the thumb of the right hand against the edge to be processed.
• The back of your hand must be facing upwards.
• Extend the index finger as shown.• This finger will point in the direction
that you should feed the router.

Calculating the offset
Template needs to account for the difference in diameter between the cutting bit and the guide bushing collar.

Template & guide bearing cutter
When using a bearing guided trimming bit the template can be made to the exact shape or profile required.

Routing at the corner
Cut end grain and let corners tear out
Long grain cut will remove torn-out material
Eliminating end grain tear out
