Centerless grinder and internal and external cylindrical compound grinding: ways to improve the efficiency of precision parts processing
Choose centerless grinding for mass production
If there are a large number of shaft parts and sleeve parts and the shapes are regular, then the centerless grinder is the most worry-free choice. It does not use a center for fixation, and it does not need to drill holes at both ends of the workpiece to achieve positioning. Instead, the workpiece is directly placed between the grinding wheel and the guide wheel to start processing. In this way, the loading and unloading process is extremely smooth, and a batch of parts can pass through continuously. It is especially suitable for mass-produced products such as automobile bearings and medical equipment.
Centerless grinding efficiency depends on grinding wheel adjustment
Purchasing a good grinder is only the first step, and the matching of the grinding wheel and the guide wheel is equally important. Many factories use high-quality equipment, but the surface of the workpiece often appears black or has poor roundness. Selecting the appropriate grinding wheel hardness and guide wheel material, and regular dressing, can further improve efficiency. After optimization, many domestic companies have increased their production capacity by about 30%.
Complex parts molded in one go
Some parts are precision parts processed and have complex structures, including outer circles, inner holes, and end faces to be processed. In the past, the traditional method was to perform rough machining on the lathe, then switch to the cylindrical grinder, and then switch to the internal cylindrical grinder. The machine was transported back and forth multiple times and clamped. It was extremely difficult to ensure accuracy. If it is replaced by an internal and external cylindrical compound grinder, each process can be completed in one clamping, greatly reducing positioning errors.
Where are compound grinders used?
This type of composite machine tool precision parts processing is suitable for processing more difficult precision parts. Valve cores in semiconductor equipment are typical application scenarios. Centerless grinders and internal and external cylindrical compound grinding: ways to improve the efficiency of precision parts processing. Precision sleeves in optical instruments are one of the typical application scenarios. Core components in high-end medical equipment are typical application scenarios. Although the investment in equipment is relatively high, considering the overall processing cycle and the pass rate, the overall cost is more cost-effective.
Choosing equipment depends on the characteristics of the parts
When choosing a machine tool for processing precision parts , the more expensive the machine is, the better it is, and the most efficient machine does not necessarily mean it is suitable for you. The key is to first analyze the characteristics of your own parts, look at factors such as output requirements, accuracy levels, material properties, and then match the appropriate type of equipment. For large batches of standard parts, centerless grinding should be given priority, while in the case of small batches of multiple varieties or parts with complex shapes, compound grinders are more suitable.
Professional support is important
When selecting equipment, what needs to be relied on is not just the comparison between parameters, but also a complete set of process plans to support it. A good supplier will help you analyze the existing production status, give customized process suggestions, and even design special equipment for OEM if necessary. Choosing a reliable service provider can reduce many unnecessary detours and maximize the value of the equipment.
