What is a planer?

Workers who operate planers are called planers. "Gantry planer" is a kind of planer.

Belt drive gantry planer

belt-drive double housing planer

Gantry horizontal long bed planer. Gantry planer is mainly used for planing large workpieces, and can also clamp multiple parts on the workbench for simultaneous processing. The workbench of the gantry planer takes the workpiece through the gantry frame for linear reciprocating motion, and the idle stroke speed is greater than the working stroke speed. Generally, there are two vertical tool holders on the cross beam, and the slide seats of the tool holders can rotate at a certain angle in the vertical plane, and can do transverse feed movement along the cross beam (see machine tool); The planer can move vertically or obliquely on the tool rest; The crossbeam can be adjusted up and down on two upright posts. Generally, two columns are also equipped with side tool holders, which can move up and down along the columns to expand the processing range. When the workbench returns, it can mechanically lift the tool to avoid scratching the surface of the workpiece. The driving of machine tool table can be regulated by generator set or SCR DC, which has a wide range of speed regulation and can obtain a large driving force at low speed. Some planers are also equipped with milling heads and grinding heads, which are converted into planer milling machines and planer milling machines. The worktable can be used for both fast main motion and slow feed motion, and is mainly used for planing, milling and grinding the plane of heavy workpieces at one time.
