Types and differences of grinding machines

Grinder is the most variety of all kinds of metal cutting machine tools. The main types include cylindrical grinder, internal grinder, surface grinder, centerless grinder, tool grinder, etc.

Cylindrical grinder is the most widely used grinder, which can process all kinds of cylindrical and conical outer surfaces and shaft shoulder end faces. The universal cylindrical grinder is also equipped with internal grinding accessories, which can grind inner holes and inner and outer conical surfaces with large taper. However, the degree of automation of cylindrical grinder is low, which is only suitable for small and medium-sized batch single piece production and repair.

The spindle speed of grinding wheel of internal grinder is very high, which can grind the surface of cylindrical and conical inner hole. Ordinary internal grinder is only suitable for single piece and small batch production. Automatic and semi-automatic internal grinder can not only carry out the work cycle automatically, but also measure automatically in processing. Most of them are 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 grind the surface of the workpiece with the periphery or end face of the grinding wheel; Centerless grinder usually refers to centerless cylindrical grinder, that is, the workpiece does not need the centering and support of the center or chuck, but takes the grinding cylindrical surface of the workpiece as the positioning surface. The workpiece is located between the grinding wheel and the guide wheel and supported by the support plate. This grinder has high production efficiency, easy to realize automation and is mostly used in mass production.

Tool grinder is a grinder specially used for tool manufacturing and tool grinding, including universal tool grinder, drill edge grinder, broach edge grinder, tool curve grinder and NC tool grinder (such as bpx5 five axis linkage NC tool grinder of Beiping machine tool), which are mostly used in tool workshops of tool manufacturers and machinery manufacturers.

The abrasive belt grinder takes the fast-moving abrasive belt as the grinding tool. The workpiece is supported by the conveyor belt. The efficiency is several times higher than that of other grinders, and the power consumption is only a fraction of that of other grinders. It is mainly used to process large-size plates, heat-resistant and difficult to process materials and mass-produced plane parts.

Specialized grinding machine is a kind of grinding machine specialized in grinding a certain kind of parts, such as crankshaft, camshaft, spline shaft, guide rail, blade, bearing raceway, gear and thread. In addition to the above categories, there are honing machines, grinding machines, coordinate grinding machines and billet grinding machines.
