In the field of mould manufacturing, CNC machining centres play a vital role, which is mainly responsible for the core components of moulds such as die nuts, inserts and the precision machining of brass. The quality of these components is directly related to the mould forming effect.

The Development of Micro-Cutting Technology and Micro-Machines Abstract: Micro-machining technologies are set to become an indispensable key technological force in the future; among these, cutting technology, as the most fundamental processing step, requires continuous study and mastery. At the same time, micro-machines have emerged in response to this need.

Accuracy Assurance in Machining ProcessAccuracy Assurance in Machining ProcessAccuracy Assurance in Machining ProcessOverview of Machining AccuracyMachining accuracy refers to the degree of conformity of geometric parameters such as size shape position of the machined part with the design requirements in the machining process.

Following decades of development, prototype manufacturing has evolved into three core process systems centred on CNC precision machining, 3D printing rapid prototyping and vacuum casting. This article will examine these systems from four key perspectives: process principles, strengths and weaknesses, material suitability, and application scenarios.

Vibrating screening equipment is an important equipment necessary for mining, mineral processing, coal processing, building materials, chemical industry and other departments, and its performance directly affects the production capacity and technical and economic indicators. For vibrating screen, the same fault may be caused by different reasons, and the solution may not be the same.

The heat-affected zone is the region where the microstructure and mechanical properties of the material change due to the effects of heat (without melting) during the welding process. The microstructure and properties of the weld metal resulting from recrystallisation are related to the chemical composition of the weld, the cooling rate, and the post-weld heat treatment.

In the field of precision manufacturing, the demand for multi-species and small-lot orders is increasingly becoming mainstream, with companies in the aerospace, precision mould and medical device industries

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).

Many factories are also exploring various ways to tackle the problem of welding fume pollution in their welding workshops; however, due to certain factors, efforts to control welding fumes are often unsatisfactory, failing to meet environmental assessment standards, or having passed the environmental assessment at the time
