A surface planing machine features a motor with a cutter-head that rotates at a high speed. Wood surface planers are usually quite large and heavy, which is why they are often placed onto a dedicated surface like a plane bench or a table. Surface planers can differ in size, whereas the size of the planer also determines the size of the boards that can be processed. A typical surface planer is made out of a long surface table with a planing shaft mounted in the middle and two planing knives.

The surface table is split into two parts: an infeed and an outfeed. The non-adjustable outfeed corresponds with the height of the cutting circle. The chip removal of the workpiece is determined by the height-adjustable infeed. There are several types of knife-driving shafts, the most common ones being a traditional cutterblock and a spiral knife.
