What's the structural difference between planing and planing?

Structure of planer: Planer is generally composed of lathe bed, front and back tables, cutter shaft, guide ruler, transmission mechanism and operating mechanism. As a basic planer, it is simple to operate independently, and it is as active as a saw planer in small and medium-sized wood workshops.

Structure of planer: The planer consists of a lathe bed, a workbench, a workbench lifting mechanism, a cutter shaft, a pressing mechanism, a feeding mechanism, a transmission mechanism and an operating mechanism. The press planer has a high degree of automation, and has developed single-sided planer, double-sided planer and four-sided planer. And the processing efficiency is high.

Difference: when planing wood, the planer is fed by external force, the wood processing surface is the datum plane, the planer has its own feeding mechanism, and the other side of the wood processing surface is the datum plane. If the planer and planer use the same cutter shaft model, the blades can be used interchangeably. If different cutter shafts are used, it is necessary to confirm whether the blades can be used interchangeably according to the actual situation.
