Surface planer / jointer – flat reference faces and square edges
A surface planer, also called a jointer, prepares solid timber by producing a flat reference face and an edge square to that face. It provides the basis for subsequent machining to size.
Operation and construction
The machine has infeed and outfeed tables with a cutterblock between them. Adjusting the infeed table determines the depth of cut. Long, rigid tables support workpiece guidance.
A fence establishes the edge angle. Depending on the equipment, it can be set for square or bevelled edges. Cutterblock systems, table adjustment, guarding and dust extraction vary with machine configuration.
Applications
Surface planers prepare boards, planks and other solid timber components, for example in furniture making and interior joinery. The resulting reference face subsequently rests on the thicknessing table.
Application and classification
Surface planing establishes a flat face and a defined angle. A thickness planer machines the opposite face parallel to it at the required thickness. These functions are available in separate machines or combined planer-thicknessers. Working width and permitted depth of cut depend on the individual machine.
