The planer type milling machine can simultaneously process the surface by using a plurality of milling cutters, has higher processing precision and production efficiency, and is suitable for processing the plane and the inclined plane of a large-scale workpiece in batch and mass production. The numerical control planer type milling machine can also process space curved surfaces and some special parts. The planer is similar to a planer in appearance, except that the cross beam and the upright are not planer tool holders but milling tool holders with a headstock, and the reciprocating motion of the longitudinal table of the planer is not the main motion but the feeding motion, and the rotary motion of the milling cutter is the main motion. The main parameter of the planer type milling machine is the width of the working table surface, and the planer type milling machine also takes the width of the planer type milling machine as a parameter.

The numerical control planer type milling machine with the model SK2015-3 refers to a planer type milling machine with the width of 1.5 meters and the length of a workbench of 3 meters, in other words, a workpiece with the width of 1.5 meters and the length of 3 meters can be processed. According to the condition that the portal frame moves or not, the portal frame is divided into a portal frame fixed workbench which moves more than 90% and a portal frame movable workbench which is also called bridge type. The bridge type gantry milling machine is characterized by small occupied area, large bearing capacity, and a gantry travel of 20 meters, thereby being convenient for processing extra-long or extra-heavy workpieces.

According to whether the cross beam moves on the upright post, the cross beam is divided into a movable beam type and a fixed beam type; the movement of the cross beam over the overhead bed is referred to as overhead.

The system is divided into a common type and a numerical control type, and manufacturers develop a numerical intelligent planer type milling machine with the conversion of common milling and numerical control milling by one key, so that the planer type milling machine is more flexible and practical. Capacity is divided into light, medium and heavy, and extra heavy planer mills.
