Tenoning Machine


a woodworking machine for making tenons and lugs on parts to be joined in woodworking enterprises.

Machines may be designed to fashion frame or box tenons. On some machines the tenons are cut on one end of the workpiece with each operating cycle (single-side machines); in others tenons are cut simultaneously on both ends during one cycle (doubleside machines). Machines of the first type operate in steps; those of the second type feature straight-through operation. Machines for fashioning box tenons can form both straight-sided and dovetail tenons. Straight-sided tenons are formed by ordinary milling-type planers mounted on the machine spindle; dovetail tenons are formed by end-milling planers mounted on vertical spindles. On double-side box-tenoning machines, the operating cycle is a combination of the step and straight-through formats: the ends of the workpieces are filed to size as the workpiece is moved, and the tenons are formed as the workpiece is held stationary. Frame tenons are cut on both types of machines.

On a single-side tenoning machine the workpiece is secured to the machine table, which executes a reciprocating motion; on double-side machines the workpiece is held by special chains and supports that execute continuous translatory motion. The workpiece is first cut to the necessary dimensions, and then the tenons or lugs are fashioned.

Tenoning machines have rigid, cast frames, tables with clamping mechanisms, and special columns on which are mounted tool heads with saws, milling-type cutters, or lug-cutting disks. The spindles rotate at speeds ranging from 3,000 rpm (on machines for straight-sided and frame tenons) to 9,000 rpm (on machines for dovetail box tenons).
