Grinding machine VS. Milling machine
Grinding machines and milling machines are commonly used tools in the machine processing industry, they are processed by cutting tools, but their principles and scope of application are different.
The grinding machine is through the rotation of the grinding wheel for precision grinding and polishing of the workpiece, can process high-precision parts under the accuracy of thousands of millimeters; However, its processing efficiency is relatively low, because more heat and chips are generated during grinding.
The milling machine is to cut the workpiece by rotating milling cutter, which can process a variety of shapes and contours. Milling machine processing efficiency is relatively high, but its processing accuracy is mainly affected by the quality and precision of the tool.
1.The difference between grinding machine and milling machine
1.1 Different cutting principles
The grinding machine grinds the workpiece through the grinding wheel, so that the workpiece surface reaches a certain precision and finish. The milling machine is to cut and process the workpiece by rotating milling cutter.
1.2 Parts processing forms are different
Grinding machine processing is usually suitable for parts with high precision and high surface smoothness requirements, while milling machine is suitable for parts processing with diverse shapes.
1.3 Different machining accuracy
Grinding machine processing has the advantages of high precision and high surface quality, while milling machine processing has the characteristics of high efficiency and relatively low precision.
2.Application areas of grinders and milling machines
The grinding machine is suitable for workpiece with high hardness and strict precision requirements, such as high-speed cone bearings, quartz glass and so on. Mainly used in the manufacture of automobiles, aircraft, electronic equipment and other high-precision demand parts, such as bearings, rollers, gears, grinding mold, die cutter and so on.
The milling machine is suitable for processing complex shapes, sizes and quantities of workpieces such as plane, curved surface and spiral, such as turning center parts, forging dies, cold extrusion spare parts, etc. Mainly used in metal processing, wood processing, mold processing, aerospace, weapons, shipbuilding, electronic communications, such as shaft sleeve, tie rod, railway switch, lathe, crafts and so on.
3.Their strengths and weaknesses
3.1 Advantages of grinding machine
The surface quality and accuracy of the grinding machine are higher than those of the parts processed by the milling machine, which is suitable for some high-precision and high-surface quality processes.
3.2 Advantages of milling machines
Milling machine processing efficiency is high, the cost is relatively low, more widely used. Suitable for parts with diverse shapes and simple process requirements.
4.Summary
Grinding machine and milling machine two different processing methods have their own unique advantages and disadvantages, the choice should be considered according to the specific requirements. In general, when processing the workpiece, it is necessary to weigh the actual production situation and choose a more suitable tool for processing. Understanding and mastering their application in different projects can improve processing efficiency, reduce costs and improve product quality, which is of great help to related industries.
