Precision machining refers to the process of accurately machining workpieces using high-precision machine tools and specialized tools. This processing process can meet very high requirements for the accuracy, surface quality, and shape of the parts. Precision machining usually includes processes such as turning, milling, grinding, and boring. Among them, turning is a common processing method that can produce various shapes of outer circles, inner circles, and surfaces. Milling is a method of rotating a milling cutter to cut a workpiece, commonly used to manufacture flat surfaces, chamfers, and various shapes of contours. Grinding is a method of cutting a workpiece using a grinding stone, mainly used to improve the accuracy and surface quality of the workpiece. Boring is a method of machining holes, which produces precise shapes and dimensions through the movement of a rotating tool within the hole.

The advantages of precision machining are mainly reflected in the following aspects. Precision machining can achieve high-precision machining and meet the processing needs of various complex parts. Secondly, precision machining has high efficiency, which can greatly shorten the manufacturing cycle and improve production efficiency. Once again, precision mechanical processing has a high degree of automation, which can reduce manual operations and improve the consistency and stability of processing. Precision machining also has the characteristics of flexibility and strong adaptability, which can be adjusted and optimized according to different product requirements.

What are the processes of precision machining in Dalian?

Milling. Milling is a machining method that uses a rotating milling cutter to remove material from a workpiece. The milling process can be used to process various shapes of grooves, keyways, planes, etc., and different machining effects can be achieved through different cutting methods.

Drill holes. Drilling is a common precision machining process that uses rotary cutting tools to remove material from the workpiece and form holes. Drilling can be used to process different types of holes such as hollow holes, blind holes, and through holes.

Broaching. Broaching is a machining method that involves stretching and cutting materials through tensile force. This processing process is usually used to process rod shaped workpieces, which can achieve effects such as reducing the diameter of slender rods and improving surface smoothness.

Grinding. Grinding is a method of cutting the surface of a workpiece using abrasives and grinding tools. The grinding process can be used to process high-precision flat, cylindrical and other parts, which can improve the quality of the workpiece surface and meet the requirements of workpiece size, shape, and accuracy.

Turning. Turning is a machining method that removes material from a workpiece by rotating it relative to the cutting tool. The turning process can be used to process various shapes of outer circles, inner circles, conical surfaces, spherical surfaces, etc., which can achieve the precise size and shape requirements of the workpiece.

Planing. Planing is a method of cutting the surface of a workpiece using a planer tool. The planing process is usually used to process large-sized flat and grooved parts, which can achieve efficient cutting and improve the quality of the machined surface.

In the process of precision machining, the appropriate material selection is crucial for the machining results. Commonly used materials include metal materials (such as cast iron, aluminum alloy, steel, stainless steel, etc.) and non-metallic materials (such as plastic, ceramics, glass, etc.).
