Introduction to the types of mills and their uses

Grinding machines have the most variety among all types of metal cutting machine tools. The main types are cylindrical grinders, internal cylindrical grinders, surface grinders, centerless grinders, tool grinders, etc. Cylindrical grinders are the most widely used grinders that can process various cylindrical and conical outer surfaces and shaft shoulder end faces. The universal cylindrical grinder also has an internal grinding attachment, which can grind the inner hole and the inner and outer cones with a large taper. However, the degree of automation of the cylindrical grinder is low, and it is only suitable for small and medium batches of single-piece production and repair work. The grinding wheel spindle speed of the internal cylindrical grinder is very high, and it can grind the surface of cylindrical and conical inner holes. Ordinary internal cylindrical grinders are only suitable for single piece and small batch production. Automatic and semi-automatic internal grinders can be used for automatic measurement during processing in addition to the automatic operation of the work cycle, and are mostly used in mass production. The workpiece of the surface grinder is generally clamped on the worktable, or fixed on the electromagnetic worktable by electromagnetic suction, and then the periphery or end face of the grinding wheel is used to grind the surface of the workpiece. The centerless grinder usually refers to the centerless cylindrical grinder. , That is, the workpiece does not need to be centered and supported by a center or a chuck, but uses the ground surface of the workpiece as the positioning surface, and the workpiece is located on the grinding wheel and the guide wheel. Supported by a pallet, this kind of mill has high production efficiency, is easy to realize automation, and is mostly used in mass production.

Large crankshaft grinder tool grinder is a grinder specially used for tool manufacturing and tool sharpening. There are universal tool grinders, drill sharpening machines, broach sharpening machines, tool curve grinders, etc., which are mostly used for tool manufacturing In the tool workshops of factories and machinery manufacturing plants, abrasive belt mills use fast-moving abrasive belts as abrasive tools, and the workpieces are supported by conveyor belts. The efficiency is several times higher than other mills, and the power consumption is only a fraction of other mills. 1. It is mainly used for processing large-size plates, heat-resistant materials that are difficult to process, and mass-produced flat parts. Specialized grinding machines are grinding machines that specialize in grinding certain types of parts, such as crankshafts, camshafts, spline shafts, guide rails, blades, bearing raceways, gears and threads. In addition to the above categories, there are also various types of cloth mills, grinders, coordinate mills and billet mills.
