Grain size and hardness of grinding wheel and grinding tool for CNC end face cylindrical grinder

2025-04-08

1、 Grain size of grinding wheel and grinding toolGrinding tool particle size refers to the dimensions of the geometric shape of the grinding particles. Industry standards divide the grinding particles into 41 particle size numbers based on the specifications of high-precision CNC end face cylindrical grinders. The selection of grinding tool particle size can directly affect the roughness and grinding efficiency of the workpiece. Generally speaking, using a coarse-grained grinding wheel has high grinding efficiency, but the surface roughness of the workpiece is poor. When grinding with a fine-grained grinding wheel, the surface roughness of the workpiece is good, but the grinding efficiency is low. In short, under the specified conditions, coarse-grained grinding tools should be used as much as possible to ensure high grinding efficiency.2、 Hardness of grinding wheel and grinding toolThe hardne...

Introduction to the main functions of each component on the cylindrical grinder

What requirements does the base of a CNC cylindrical grinder need to meet

2025-04-08

The base of a large CNC cylindrical grinder is the basic support for the entire Y-axis, usually used to place important components such as guide rails. In order to meet the requirements of high-speed, high productivity, high reliability, high precision, and high automation of CNC machine tools, and compared with ordinary machine tools, CNC machine tools need to have higher static and dynamic stiffness, as well as good vibration resistance. The base mainly proposes requirements in five aspects.1. High precision: There are many machined surfaces for installing components and guide surfaces for moving parts on the base, and these surfaces require high precision and mutual positional accuracy, which can be maintained for a long time. In addition, during cutting, all dynamic and static loads on the machine tool are often transmitted to the base, making the forces on the base very complex. To ensure the mutual po...

Briefly explain the classification of cylindrical grinders

2025-04-07

An external cylindrical grinder generally consists of a cast iron bed body, a worktable, a headstock and tailstock that support and drive the workpiece to rotate, a grinding wheel rack (grinding head) that installs the grinding wheel, a transverse feed mechanism that controls the size of the grinding workpiece, and electrical and hydraulic devices that control the movement of the machine tool's moving parts. It is mainly divided into the following types:Cut in equipment: When the length of the workpiece grinding part is less than the width of the grinding wheel, the grinding wheel only needs to make continuous lateral feed without relative axial movement with the workpiece, and this equipment has high productivity.End face cylindrical grinder: The grinding wheel holder is tilted at an angle around the vertical axis, and the grinding wheel surface is polished into two grinding surfaces parallel and perpendic...
