The centerless grinder is composed of three mechanisms: grinding wheel, adjusting wheel, and workpiece support. The grinding wheel actually performs the grinding work and helps the workpiece obtain sufficient feed speed. When using this device, operators can arrange and combine these three mechanisms to create several coordinated working methods, which can be used to handle various different products. With the development of the grinder industry, a type of centerless grinder with shortened horizontal dimensions has emerged. This equipment is particularly suitable for use in a small installation space and can handle products of various shapes, helping users save space. This grinder equipment greatly reduces the lateral size of the centerless grinder and meets the user's space saving requirements, as there is no need to maintain a space for the grinding wheel dressing unit on the side of the grinding...

Instructions on the operating procedures for CNC cylindrical grinding machines

2022-10-10

CNC cylindrical grinder is a structurally simple, operationally convenient, and adaptable cylindrical grinder suitable for grinding inner, outer cylindrical, and conical workpieces. It is suitable for use in workshops with single piece, small batch, and batch production. The workpiece rotation, outer circular grinding wheel, inner circular grinding wheel, oil pump, and cooling are respectively driven by motors. The headstock motor adopts a permanent magnet DC motor to achieve stepless speed change of the workpiece through the motor speed control plate. The longitudinal movement of the machine tool worktable can be achieved by hydraulic stepless rotation or by handwheel rotation. The lateral feed movement of the grinding wheel rack has several forms, including hydraulic movement, automatic periodic feed, and manual feed. The operating procedures for CNC cylindrical grinding machines are as follows: 1....

Working mode and influencing factors of CNC end face cylindrical grinder

2025-04-07

CNC end face cylindrical grinder is a grinder used to machine the outer surface and shoulder end face of cylindrical, conical, or other shaped elements of workpieces; Widely used, capable of processing various cylindrical conical outer surfaces and shaft shoulder end face grinders.Working method: Mainly used for grinding outer cylindrical surfaces and conical surfaces, there are two basic grinding methods: longitudinal grinding method and cutting in grinding method.
