The milling machine mainly refers to a machine tool that uses a milling cutter to process various surfaces of a workpiece. Usually the milling cutter mainly moves by rotation, and the movement of the workpiece and the milling cutter is the feed movement. It can process planes, grooves, various curved surfaces, gears, etc.

A milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads, and spline shafts, milling machines can also process more complex profiles. The efficiency is higher than that of planing machines. It is widely used in machinery manufacturing and repair departments.

The milling machine is a machine tool with a wide range of uses. It can process planes (horizontal planes, vertical planes), grooves (key ways, T-slots, dovetail grooves, etc.), gear parts (gears, spline shafts, sprockets), Spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the revolving body and cut off the work.

When the milling machine is working, the workpiece is mounted on the worktable or the indexing head and other accessories, the milling cutter rotates as the main movement, and is supplemented by the feed movement of the worktable or the milling head, and the workpiece can obtain the required processing surface. Because of the multi-edge intermittent cutting, the productivity of the milling machine is high. Simply put, a milling machine is a machine tool that can mill, drill, and bore a workpiece.

The grinder is a machine tool that uses abrasive tools to grind the surface of the workpiece. Most of the grinders use high-speed rotating grinding wheels for grinding, a few use other abrasive tools such as oil stone, belts and free abrasives for processing, such as honing machines, super-finishing machine tools, belt grinders, grinders and polishing machine waiting.

The grinder can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; it can also process brittle materials, such as glass and granite. The grinder can perform high-precision and small surface roughness grinding, as well as high-efficiency grinding, such as powerful grinding.

According to the movement characteristics and process requirements of the grinder, the following requirements are imposed on electric drive and control:
1. The rotational movement of the grinding wheel generally does not require speed regulation, it can be driven by a three-phase asynchronous motor, and only requires one-way rotation. When the capacity is large, Y-triangular step-down start can be used.
2. In order to ensure the processing accuracy, make it run smoothly, and ensure that the inertia of the worktable is small and no impact when the reciprocating movement of the worktable is reversed, hydraulic transmission is adopted to realize the reciprocating movement of the worktable and the lateral feed of the grinding wheel box.
