BTA processing refers to high-precision, high-quality medium to large diameter deep hole machining.
When it comes to BTA processing and gun drilling, Fujishin Seisakusho is the best! We possess outstanding deep hole processing technology in Japan!
"BTA processing" is a machining technology that can create high-performance deep holes with medium to large diameters, while also achieving a good surface finish. Fujishin Seisakusho's BTA processing possesses top-level technology in Japan, allowing for deep hole machining that other processing companies find difficult to perform. [If you have been turned down by other companies for deep hole machining, there is a possibility that Fujishin Seisakusho can manufacture it!] [BTA Processing - Machining Hole Diameter] ○ Machining hole diameter (mm): φ24 - φ75 ○ Maximum outer diameter × material length: up to φ300 x 1300 (1500) mm * The maximum machining length for each processing diameter varies depending on the length of the boring bar. * If you are having trouble with the accuracy or quality of deep hole machining, please contact Fujishin Seisakusho. * Please view the "Manufacturing Case Collection" PDF data available for download.
