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 demanded. 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 micro-machining and mold technology. In the technical information magazine "Micro Machining Technology News Vol.10," this month's column discusses the causes and countermeasures for sink marks in molded products, as well as micro-grooving and micro-hole processing. [Contents] - This month's column by Goto Seiki employees: What is simultaneous five-axis machining? Specific examples at Goto Seiki. - Causes and countermeasures for sink marks in molded products. - Micro-grooving and micro-hole processing. For more details, please contact us or download the catalog.

basic information

[Content] [Employee's Column for This Month] ○ What is simultaneous five-axis machining? Specific examples at Goto Seiki ○ With the machining center that features simultaneous five-axis control, machining from multiple directions can be achieved in a single setup, resulting in cost reduction. ○ Since the need for detachment and origin setting between processes is eliminated, ensuring accuracy becomes easier. ○ Shapes that are impossible to achieve with three-axis machining can be processed using simultaneous five-axis machining. [Causes and Countermeasures for Shrinkage in Molded Products] ○ The main causes of shrinkage include issues related to part shape, materials, mold design, and molding conditions. ○ As countermeasures, it is important to address molding conditions, consider factors such as ribbing, gate position, gate diameter, and venting during mold design, and make adjustments while paying attention to the dimensions of the molded products. [Micro Groove and Micro Hole Machining] ○ We introduce the minimum diameter groove and hole machining that can be performed at Goto Seiki. ○ We have a track record of continuous machining of 35 grooves with a groove width of 0.15mm and a plate thickness of 0.1mm between grooves. ○ We have a track record of continuous machining of 7,000 pieces with a hole diameter of φ0.12 and a depth of 0.3mm. ● For more details, please contact us or download the catalog.
