What are the technical contents of machining?
Processing includes:

Turning (vertical turning, horizontal turning): Turning is the process of cutting metal from the workpiece. When the workpiece rotates, the cutter cuts into or rotates along the workpiece;

Milling (vertical milling, horizontal milling): milling is a process of cutting metal with a rotating tool, which is mainly used to process grooves and straight surfaces, and can also process cambered surfaces of two or three axes;

Boring: Boring is a processing method to enlarge or further process the drilled or cast holes on the workpiece. Mainly used for machining holes with large shape, large diameter and high precision.

Planing: the main feature of planing is to process the straight surface of the shape, and the surface roughness is generally not as high as that of milling machine;

Slotting: slotting is actually a vertical planer, and its cutter moves up and down, which is very suitable for non-complete arc machining, mainly used for cutting some types of gears;

Grinding (plane grinding, cylindrical grinding, inner hole grinding, tool grinding, etc.). ): Grinding is a kind of machining method to remove metal with grinding wheel. The machined workpiece is accurate in size and smooth in surface. It is mainly used for finishing the workpiece after heat treatment to make it reach the accurate size.

Drilling: drilling is to drill a hole on a solid metal workpiece with a rotary drill; When drilling, the workpiece is positioned, clamped and fixed; In addition to rotation, the drill bit should also be fed along its own axis.

There are many types of machining involved in machining, and the above types are common at present, which can meet the processing technology required by all the workpieces at present.
