Grinding machine introduction

Grinding is widely used and is one of the main methods for processing customized precision parts.
Grinder (grinding machine) is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other abrasive tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishers.

Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; they can also process brittle materials, such as glass and granite - these materials may be difficult to process with CNC machining. Grinding machines can perform high-precision and very small surface roughness grinding, and can also perform high-efficiency grinding, such as strong grinding.
Classification:
Grinding machines With the increase in the number of high-precision and high-hardness mechanical parts, as well as the development of precision casting and precision forging processes, the performance, variety and output of grinding machines are constantly improving and growing. (1) External cylindrical grinding machine: It is a basic series of ordinary types, mainly used for grinding cylindrical and conical external surfaces. (2) Internal cylindrical grinding machine: It is a basic series of ordinary types, mainly used for grinding cylindrical and conical internal surfaces. In addition, there are grinding machines with both internal and external cylindrical grinding. (3) Coordinate grinding machine: It is an internal cylindrical grinding machine with a precision coordinate positioning device. (4) Centerless grinding machine: The workpiece is clamped by centerless clamping, generally supported between the guide wheel and the bracket, and the workpiece is driven to rotate by the guide wheel. It is mainly used for grinding cylindrical surfaces. For example, bearing shaft support, etc. (5) Surface grinding machine: It is mainly used for grinding the plane of the workpiece. a. Hand-cranked grinders are suitable for processing smaller-sized and higher-precision workpieces, and can process various special-shaped workpieces including arc surfaces, planes, grooves, etc. b. Large water grinders are suitable for processing larger workpieces. The processing accuracy is not high, which is different from hand-cranked grinders. (6) Belt grinder: A grinder that uses a fast-moving abrasive belt for grinding. (7) Honing machine: Mainly used for processing various cylindrical holes (including light holes, axial or radial intermittent surface holes, through holes, blind holes and multi-step holes), and can also process conical holes, elliptical holes, and trochoidal holes. (8) Grinding machine: A grinder used to grind the plane or cylindrical inner and outer surfaces of workpieces. (9) Guideway grinder: A grinder mainly used for grinding the guideway surface of machine tools. (10) Tool grinder: A grinder used for grinding tools. (11) Multi-purpose grinder: A grinder used for grinding cylindrical, conical inner and outer surfaces or planes, and can use follow-up devices and accessories to grind a variety of workpieces. (12) Special grinder: A special machine tool engaged in grinding a certain type of parts. According to the processing object, it can be divided into: spline shaft grinder, crankshaft grinder, cam grinder, gear grinder, thread grinder, curve grinder, etc. (13) End grinder: A grinder used for grinding the end face of a gear.
