Do You Know the Difference Between Planer Machine and Slotting Machine

A planer is a type of metalworking machine tool that uses the linear relative motion between the workpiece and a single-point cutting tool to cut the workpiece. A planer is similar to a shaper but larger, and with workpiece moving, whereas in a shaper the cutting tool moves. With planer processing, the tool is simple, so product efficiency is low. It is suitable for a single piece, small batch production, and machine repair shop, and is often replaced by a milling machine in mass production.


There are many types and models of planers. According to its structural characteristics, it can be divided into a shaper and slotting machine.

The shaper

The planer is a planer used to plan medium and small workpieces. The length of the workpiece is generally less than 1m.  We clamp the workpiece on an adjustable workbench or clamp it in machine vice, and use a planer for planing. According to the length of the workpiece that can be processed, the planer can be divided into three types: large, medium, and small. The small planer can process workpieces up to 400mm in length, such as B635. The medium-sized planer can process workpieces with a length of 400~600mm, such as the B650. A large planer can process workpieces with a length of 400~1000mm, such as B665 and B690.

Slotting machine

The slotting machine is also called a vertical planer, suitable for processing the inner surface of the workpiece. Its structure is almost the same as that of a shaper. The main difference is that the inserting tool performs linear reciprocating motion in the vertical direction. In addition to vertical and horizontal motion, the worktable can also perform rotary feed motion in the circumferential direction. According to the different transmission modes, the planer has a mechanical transmission and hydraulic transmission of two types: mechanical shaper, gantry planer, and slotting machine. Hydraulic shaping machine and slotting machine.
