Heat treatment is a thermal process in which steel is heated to a predetermined temperature in the solid state, held at that temperature for a certain period of time, and then cooled down at a certain rate. It is widely used in the machinery manufacturing industry, and this paper

Machining error is the degree of deviation between the actual geometric parameters (geometric dimensions, geometric shape and mutual position) and the ideal geometric parameters of a machined part.

Optimisation of machining process By Xu Great [Abstract] In the process of machining, the machining accuracy of parts directly affects the quality of mechanical products. This paper takes the machining process of parts as an example and introduces the machining process flow.

[Abstract] The machining process includes roughing and finishing, and its influence on the machining accuracy of the parts is mainly manifested as the intrinsic influence, the influence of force and the influence of thermal change. In order to make the machining accuracy to meet the prescribed standards, for these influencing factors, in the processing of parts

First, in order to ensure that the thread of the guide, processing spindle rotation week, the feed of the tool must be equal to the thread of the guide, the feed is larger; in addition, the strength of the threaded tool is generally poor, so the threaded tooth type is often not once processed, the need for many times for cutting.

The main reason why novice welders can't match the current and voltage is that they don't know the relationship between the two, and they don't know what role they play. Current is to control the weld depth (current can also be understood as the wire feed speed, the greater the current, under the condition of constant voltage).

Technical Brief: This patent proposes an automatic loading and unloading mechanism for the problems of low efficiency and big safety risks of manual loading and unloading in traditional bar processing. Through the hydraulic drive lifting body with pneumatic horizontal moving device, to achieve synchronous lifting and transverse displacement of the block

Mould has a complex structural profile, high precision requirements, high hardness of the materials used, short manufacturing cycle and so on. Mould manufacturing is a complex production process with tight production cycle requirements and high technical means. Each mould is a new project
