The mortise processing machine is mainly used for square or rectangular groove processing of wood, wood frames, and other components. The main difference between it and the drilling machine is the use of special tools, which are composed of a drill bit and a square chisel installed in a hollow square chisel. During machining, when the drill bit rotates, hollow square chisels are used for reciprocating feed motions to produce the desired square or rectangular grooves.

The main shaft of the mortise machining machine adopts a high-precision heavy cutting structure, with a rotational speed of 15000 r/min, which meets the need for high efficiency in core insertion processing. The core insertion mechanism adopts a precision cylindrical guide rail sliding bearing structure, and is equipped with a manual pressure lubrication pump, which can timely lubricate the guide rail. The mechanism has high swing frequency, high processing efficiency, and good quality. The mortise width adopts digital display and manual adjustment, which is easy to operate, convenient to adjust, and more accurate in processing. The spindle swing speed is adjusted using a friction wheel tension adjustment speed structure to adjust the speed to meet the processing needs of various materials. The tenoning operation adopts dual working tables to work alternately, and the working table can be tilted to handle oblique tenoning.
