How to determine the grinding allowance of an external cylindrical grinder

2025-04-08

Reasonably confirming the grinding allowance of the cylindrical grinder is of great significance for increasing labor productivity and ensuring machining quality. Generally speaking, grinding is a precision machining process, and compared with other cutting methods, its cutting efficiency is much lower. If the margin is too large, it will reduce productivity and increase the power consumption of the grinding wheel and machine tool.In some cases, it can also reduce the quality of the parts, such as workpieces that have undergone surface nitriding and high-frequency heat treatment. The surface layer hardness is high, and the hardness decreases as it goes inward. If the margin before precision grinding is too large, the hardness of the surface layer after grinding will not meet the requirements. Of course, the margin cannot be set too small, otherwise the machining marks or defect layers left by the previous p...

Introduction to the process of starting the grinding wheel each time on the cylindrical grinder

2025-04-08

1. Before starting the grinding wheel of the cylindrical grinder, the hydraulic on-off valve should be placed in the stop position, the adjustment handle should be placed in the low-speed position, and the grinding wheel seat feed handle should be placed in the reverse position to avoid accidents.2. Before starting the grinding wheel each time, the lubrication pump or static pressure oil supply system oil pump should be started first, and the grinding wheel can only be started after the grinding wheel spindle lubrication is normal.3. At the beginning of grinding, the feed rate should be small and the cutting speed should be slow to avoid the grinding wheel from breaking due to cold brittleness, especially in winter when the temperature is low.4. Before starting grinding, the distance between the grinding wheel and the workpiece should be adjusted to avoid collision between the grinding wheel and the workpie...

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

2025-04-08

An external cylindrical grinder is a machine tool that adds the outer surface and shoulder end face of cylindrical or conical workpieces. It can not only grind the outer surface of the workpiece, but also the cutting surface and end face of the workpiece.Usually, machine tools use grinding wheels as grinding tools to grind the surface of workpieces, which also belongs to the field of metal cutting. The structure of a machine tool is not complicated. From its appearance and the grinding action of the grinding wheel in the working area, it can be basically determined that an external cylindrical grinder is usually composed of a worktable, a headstock, a tailstock, a grinding wheel holder, a feed mechanism, as well as some electrical systems and hydraulic control devices.The bed is the core of the entire machine tool and the platform that carries all the devices and components on the machine tool. At the same ...

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...
