Jointer

 

(also, jointer planer), a woodworking machine for straight planing (milling and jointing) of workpieces along faces or edges. Jointers have a frame on which are mounted a circular knife shaft (usually with from two to four blades), a table, a vertical cutterhead, a guide (fence), and a removable or fixed feed mechanism; the last component is absent when manual feed is used. Usually, one large face and one edge are worked simultaneously. The workpiece is oriented along the fence when the vertical cutter head is removed. When a large face and an edge are worked simultaneously, the knife shaft and the vertical milling head are both used, with the latter set at an angle of 90° to the table’s surface. The table consists of a long front section, set at a height corresponding to the thickness of the layer being planed off, and a fixed rear section, whose surface is level with the height of the periphery of the cutting edges of the blades.

Jointers may be combined with thickness planers in a single machine designed for the two-sided planing of beam-shaped parts and sheets. Such combination machines have a box-shaped frame with a feeding device, four base tables, two jointing heads, and two planing heads mounted on the upper part; a blower and a drive for the feed mechanism are located inside the frame. Work-pieces are held in a magazine having transverse supports situated between two feed chains. The machines can process up to 30 workpieces simultaneously.
