What is the surface roughness of the grinder?

Semi-finishing (one-time processing) of cylindrical grinding and internal grinding is 6.3 ~ 0.8, accuracy is 0.8 ~ 0.2, accuracy is 0.2 ~ 0. 1, precision and ultra-precision grinding is 0.05 ~ 0.025, and mirror grinding (external grinding).

Grinders can process materials with high hardness, such as hardened steel and cemented carbide. It can also process brittle materials, such as glass and granite. The grinder can have high grinding accuracy, small surface roughness and high grinding efficiency, such as strong grinding.

Extended data:

According to the movement characteristics and technological requirements of grinding machine, there are the following requirements for electric drive and control: the rotating movement of grinding wheel generally does not need speed regulation, and it can be driven by three-phase asynchronous motor, which only requires one-way rotation. When the capacity is large, Y-shaped triangle can be used for step-down startup.

In order to ensure the machining accuracy, make it run smoothly, and ensure the small inertia and no impact when the workbench reciprocates, hydraulic transmission is adopted to realize the reciprocating motion of the workbench and the lateral feed of the grinding wheel box.

When installing grinding wheels, they must be assembled according to the specified methods and requirements. After static balance debugging, you can install the test. You can't use it until everything is normal. Workers should wear protective glasses at work, balance dressing grinding wheel to prevent collision.

Measuring the workpiece, adjusting or wiping the machine tool should be carried out after stopping the machine. When using the magnetic sucker, clean the disk surface and the workpiece, tighten it and suck it firmly, and if necessary, add an iron stopper to prevent the workpiece from shifting or flying out. Pay attention to the installation of grinding wheel protective cover or machine tool baffle, and stand in front of high-speed rotating grinding wheel.
