Grinders can be divided into cylindrical grinders, internal grinders, surface grinders, tool grinders, abrasive belt grinders, etc.
Cylindrical grinders are widely used grinders that can process various cylindrical and conical outer surfaces and shaft shoulder end faces. The cylindrical grinding machine also has internal grinding accessories, which can grind the inner hole and the inner and outer conical surfaces with large taper. However, the degree of automation of the cylindrical grinder is low, and it is only suitable for small and medium batch production and repair work.
The grinding wheel spindle of the internal grinding machine has a high speed, which can grind the surface of cylindrical and conical inner holes. Ordinary internal grinding machines are only suitable for single-piece and small batch production. In addition to the automatic working cycle, automatic and semi-automatic internal grinding machines can also be automatically measured during processing, most of which are used in mass production.
The workpiece of the surface grinder is generally clamped on the table, or fixed on the electromagnetic table by electromagnetic suction, and then the periphery or end face of the grinding wheel is used to grind the plane of the workpiece; the centerless grinder generally refers to the centerless cylindrical grinder, that is, the workpiece. No D-tip or chuck is used for centering and support, but the grinding outer surface of the workpiece is used as the positioning surface. The workpiece is located between the grinding wheel and the guide wheel and is supported by the pallet. This type of grinding machine has high production efficiency and is easy to implement. Automation is mostly used in mass production.
Tool grinder is a grinder specially used for tool manufacturing and tool sharpening. There are tool grinders, drill grinders, broach grinders, tool curve grinders, etc., which are mostly used in tool workshops of tool manufacturers and machinery manufacturers.
The abrasive belt grinder uses a fast-moving abrasive belt as the abrasive tool, and the workpiece is supported by the conveyor belt. The efficiency is several times higher than other grinders, and the power consumption is only a fraction of other grinders. Difficult-to-machine materials and mass-produced flat parts, etc.
Specialized grinder is a grinder that specializes in grinding a certain type of parts, such as crankshafts, camshafts, spline shafts, guide rails, blades, bearing raceways, gears and threads. In addition to the above categories, there are many types such as honing machines, grinding machines, coordinate grinders and billet grinders.
