Dalian precision machining is a complex high-tech manufacturing technology that is of great significance for the manufacturing of products and equipment in various industries. Through precise processing technology and quality control, high-precision and high-quality part manufacturing can be achieved, meeting the requirements of different fields for product quality and precision. With the continuous progress and innovation of technology, precision machining technology is also constantly developing, providing solid support for the development and progress of various industries.

The processes of precision machining include cutting, grinding, etching, and electrical discharge machining. Cutting is a commonly used machining method, which uses cutting tools to feed and rotate the workpiece, achieving cutting processing. Grinding is the process of grinding and polishing workpieces to achieve higher surface quality requirements. Etching is the use of chemical reactions to corrode a portion of the surface material of a workpiece to achieve precise shape and size. Electrical discharge machining (EDM) is the use of electrical discharge to remove materials from workpieces and achieve high-precision machining.

How do the process parameters of Dalian precision machining affect the machining effect?

Firstly, the cutting speed. Cutting speed refers to the speed of the tool during the cutting process per unit time. The high or low cutting speed directly affects factors such as cutting force, friction, and temperature during the cutting process, which in turn affects the quality of the machining surface and tool life. Generally speaking, increasing cutting speed can improve machining efficiency, but excessive cutting speed can exacerbate wear on the cutting surface and heat accumulation of the tool, reducing cutting quality and tool life.

Next is the feed rate. Feed rate refers to the speed at which a workpiece moves in the direction of tool motion per unit time. The feed rate can affect factors such as the shape of cutting chips and cutting force, directly affecting the quality of the machining surface and the magnitude of cutting force. Increasing the feed rate appropriately can improve machining efficiency, but excessively high feed rates can increase cutting force and reduce cutting limitations.

Once again, it is the cutting depth. Cutting depth refers to the thickness of the workpiece material that the tool removes during each cutting process. The depth of cutting has a significant impact on the machining effect. Increasing the cutting depth appropriately can improve machining efficiency, but excessive cutting depth will increase cutting force, increase the possibility of material damage and tool wear.

In precision machining, commonly used processing techniques include CNC machining, laser machining, electrical discharge machining, wire cutting machining, etc. CNC machining is a computer numerical control machining technology that uses computer-controlled machining equipment for processing, with the characteristics of high efficiency and precision. Laser processing is a technology that utilizes laser for cutting, welding, drilling, and other processing, with the advantages of non-contact processing and high accuracy. Electrical discharge machining (EDM) is suitable for machining metal parts, and through EDM discharge, the material is processed. Wire cutting is a machining technique that uses metal wires for cutting, suitable for processing complex shaped parts.

The development trend of precision machining mainly includes the following aspects: firstly, the improvement of machining accuracy. With the development of science and technology, people's requirements for machining accuracy of parts are becoming higher and higher. Therefore, it is necessary to continuously improve machining technology and equipment to improve machining accuracy and surface quality. The second is the automation and flexibility of processes. With the continuous development of computer technology, people have increasingly high requirements for process automation to improve production efficiency and save human resources. The third is the application of new materials and processes. With the development of new materials and the application of new processes, more choices will be provided, and higher requirements will also be placed on processing technology and equipment.
