Chipper canter blades
The chipper canter is one of the most common sawmill machines in Finnish sawlines.
Chipper canters have three different types of blades:
- Chipping blades
- Sawing blades
- Segment blades
A typical chipper canter reducer head is a straight, grooved or spiral conical frustum. The chipping blades are fastened onto a cone-like frame and the circular blade that smooths out the surface of the wood is fastened on the frame’s face.
The circular blade can be pre-sawing i.e. its diameter is bigger than that of the chipping conic frame.
If the circular blade ‘cuts second’, the outer surface is chipped first and then the circular saw simply smooths out the surface of the cant or spar into a sawn surface.
The thickness of the circular blade is 4-6 mm.
In the straight and grooved models, there are 3–8 chipping blades. In the grooved model, the reducer plate is divided into smaller segments.
Chipper canter blades are manufactured by Heinola Sawmill Machinery, AriVislanda, Söderhamn-Eriksson and Linck.
Chipper blades
The blades of industrial chippers used to produce sawmill by-products are straight blades. Available chipper models include drum and disc chippers.
In addition to the cutting blade, the blade pack includes a counter blade. The blades are made of durable and hard tool steel.
Chipper blades are sharpened using a surface grinder.
