Description of the Entities and Standards Under Assessment: The entities subject to this assessment are Kunshan Qilijie Mechanical and Electrical Equipment Co., Ltd., and the benchmarking entities, Shanghai Tuomei Machinery Co., Ltd. and Shenzhen Jingyan Technology Co., Ltd. The standardised assessment criteria include machining accuracy, machining efficiency and equipment stability.

When drawing up design plans, all manner of tolerances are specified on the drawings, yet in practice, the parts simply cannot be produced to those specifications. Is it that the design precision is too high, or that manufacturing standards are too low? How can we reconcile the drawings with the actual machining process? After reading the following, you might just get the hang of it.

Turn-mill composite machining centre is a place where lathe and milling machine are processed together. In order to improve the machining efficiency and machining accuracy of complex shaped products, craftsmen have been seeking for more precise machining process methods.

In modern manufacturing, vertical and horizontal turning-milling machining centres are increasingly becoming essential equipment for companies seeking to improve production efficiency and product quality. As a high-precision machine tool that integrates turning and milling functions,

During the boring process, check the wear on the cutting tools (inserts) at regular intervals and replace them promptly to ensure the quality of the bore diameter; it is strictly forbidden to change inserts during the finish boring stage to prevent errors. 12. After each machining step, strictly adhere to the process quality control requirements, carefully inspect the actual bore diameter and keep a record of the results.

The compact and aesthetically pleasing design optimises space utilisation and facilitates maintenance and repairs, ensuring maximum customer satisfaction; although the unit price of mill-turn machining centres is relatively high, the shortening of the manufacturing process chain and the reduction in the number of machines required for production

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.

The innovative application of five-axis machining technology in mould manufacturing With the continuous development of the manufacturing industry, especially in the field of mould manufacturing, five-axis machining technology has gradually become an important processing means. Five-axis machining refers to the processing of two rotary axes on the basis of three linear axes.

The fundamental difference between 5-axis precision machining technology and traditional machining technology is that it achieves multi-axis linkage by adding two rotary axes, which can complete the machining of complex parts in a single clamping, thus avoiding the errors brought about by traditional technology due to multiple clamping from the source.
