We would like to introduce the technical information "Microfabrication Technology News" for research and development designers.
Since its founding in 1970, Goto Seiki has cultivated cutting processing technology, particularly in the field of optical and measuring instruments, where high precision and shape requirements are essential. This has become the foundational technology for Goto Seiki in precision parts manufacturing. In the realm of development and prototyping that supports the forefront of manufacturing, this advanced cutting technology is indispensable. Additionally, we continue to evolve as a versatile group aiming for optimization in precision parts processing using non-ferrous metals and resins, as well as in microfabrication and mold technology. In the technical information magazine "Microfabrication Technology News Vol.14," we will introduce this month's column, which covers 3D data corrections performed before cutting processing programming, the role and characteristics of gates in prototype molds, and more. [Contents] - This month's column by Goto Seiki employees - Points to consider for inspection of cutting processed parts with tolerance bosses (shafts) - About 3D data corrections performed before cutting processing programming - About the role and characteristics of gates in prototype molds For more details, please contact us or download the catalog.

basic information
[Content] [Points to Note for Inspection of Machined Parts with Tolerance Bosses (Shafts)] ○ Common phenomena that occur in machined parts with bosses or shafts include the presence of R-shaped features or steps at the base of the boss, dimensional variations at the tip, middle, and base of the boss, and lack of true roundness of the boss. [3D Data Adjustments Before Machining Program] ○ For parts with large tolerances such as hole diameter, boss diameter, and plate thickness, data adjustments are made in advance to ensure that the allowance for rough machining is uniform. ○ When the shape is complex, discussions are held regarding the corners of the product (where machining R is applied), and adjustments are made for fitting with other parts to create the machining program. [Role and Characteristics of Gates in Prototype Molds] ○ Gates serve as the "entrance" for pouring molten plastic into the product shape of the mold. ○ There are various types of gates, including side gates, jump gates, pin gates, and submarine gates. ○ Each type has its advantages and disadvantages, so careful consideration is given to the placement, size, shape, and number of gates based on the product's shape and application. ● For more details, please contact us or download the catalog.
