What can be simply considered as an external cylindrical grinder? What are the main types commonly used?
The cylindrical grinder is a type of grinding machine that can be used to perform cylindrical grinding of workpieces. It is a commonly used type of grinder. The commonly used types of external cylindrical grinders are generally divided into two types: cut in type and end face type, as well as universal external cylindrical grinders.
1. The semi-automatic cylindrical grinder can enter the semi-automatic cutting in grinding or longitudinal grinding mode through fixed distance or automatic measurement control. If this method is adopted, small or batch parts can be produced. Its grinding function and processing actions can be controlled by PLC.
2. The universal external cylindrical grinder has the function of internal cylindrical grinding. Therefore, rolling bearings can be used to support the internal grinding spindle, and different pulleys can be used to obtain different speeds, thereby achieving different grinding requirements.  
On the external cylindrical grinder, the grinding wheel is an important component, so we should firmly grasp some of its instructions. Therefore, we will explain it in detail below.
The grinding wheel used on the external cylindrical grinder should meet its usage requirements on the spindle bearing. If its spindle is in a low-speed state, it should also have high bearing stiffness. In addition, for the grinding wheel rack guide rail, a cross roller rigid guide rail should be used, which can have good performance.
