  • How to use high-speed machining center reasonably for high-speed cutting

    introduction:High-speed machining centers have always played an important role in the mold and parts processing industry,Especially for mold processing。Customers choose high-speed machining centers because they can shorten the processing cycle of molds,And can meet the accuracy、Hard cutting、Roughness requirement。However, there are still many customers using a high-speed machining center for a variety of traditional processing,E.g. heavy cutting、Low revolution speed、Low feed rate, etc,Mistakenly think that a high-speed machining center can shorten the entire mold production cycle,In fact,There are also several important factors to consider,To get the most out of it。 figure1

  • The way of plastic selection

    introduction:Start selection,We could start with a primary,After comprehensive evaluation, the experiment is carried out。Primaries can be conducted in two ways,One is to select materials according to the use of products;The second is to select materials according to product requirements(Use material performance table and performance grade classification, etc);At the same time, factors such as economic cost and safety and health should be considered。 Here are some examples of industrialised plastics,Several simple materials selection methods are listed。 1、Select materials according to their use The use mainly refers to the classification of the application field of the product,It also includes the environment in which the product is used、Force type and mode of action、Use elements such as objects。 (1)Use environment

  • Grinding process quality analysis and judgment

    introduction: 1.Width size deviation in large Due to the deviation of width dimension beyond the process requirements should be judged as waste(The width size is too small in actual production,Have to be scrapped,Large width size,It can be repaired and processed into qualified products)。Causes of waste products,It is mainly improper operation,If the instrument is not right,stopwatch,The feed amount is too large or the feed is too fierce,This will produce this process waste。The other case is that the operator grinds the non-reference end face according to the process requirements,And then according to the process requirements after grinding the benchmark end face,The ferrule has reached the required size,But the ends are still there:“Black skin”exist,This should be condemned as waste。The junk
