Our motto is to never refuse a request, with the fundamental principles of high quality, low price, and short delivery time.
We design and manufacture various types of collet chucks, including suction collet chucks, inner lining collet chucks, and special collets. 【Examples of Collet Chuck Improvements】 ■ Troubleshooting for chucks using outer diameter and inner diameter collet chucks (machine stoppage issues) ■ Improvement of workpiece runout accuracy, roundness, and wall thickness after chucking ■ Increased longevity of collet chucks and surrounding components (crack prevention and wear resistance) ■ Slip prevention during processing ■ Reduction of cycle time for processed workpieces through increased rigidity of collet chucks and surrounding components ■ Reduction of setup changeover time ■ Total cost reduction through design changes (including material changes) The improvement examples mentioned above are just a small part. We will respond to various improvements, so please consult with us. However, there may be cases where improvements cannot be made at once. Nevertheless, our company will never give up as long as our customers do not. We will continue to contribute to our customers' manufacturing for the long term.

basic information
We manufacture not only steel and carbide collet chucks made by general chuck manufacturers, but also PCD and cermet collet chucks. We promise a significant improvement in wear resistance. Additionally, we produce special collets that can uniquely handle non-standard shapes, differentiating ourselves from simple round collet chucks. Furthermore, we also engage in precision machining of carbide and PCD components.

Applications/Examples of results
One of the parts used to assemble bearings is a steel front plate, but there was a problem with its susceptibility to friction. Therefore, our company developed a solid part made of a special alloy that can withstand friction. (Other parts include ultra-hard quills (shrink-fit type), all ultra-hard front plates, PCD parts (abrasion-resistant tools), and PCD shoes, etc.)

Company information
Bonki Manufacturing has been engaged in various metal processing since its establishment and has continued on this path to the present day. Utilizing that experience, we began manufacturing collet chucks around 1980. In addition to the difficulty of the processing methods, there is also the significant challenge of ensuring uniform precision. For these reasons, higher precision is required in collet chucks. Additionally, three elements—high rigidity, long lifespan, and precision—become very important. We strive to create products that satisfy our users by focusing on "material selection, optimal shapes, heat treatment conditions, structural analysis, etc." and are committed to daily research and effort. Furthermore, in the current economic situation, we are manufacturing with the latest equipment using our unique production methods to provide our users with 100% satisfaction at lower costs and faster delivery, while promoting in-house production for all processing. We will continue to challenge ourselves in the processing of difficult-to-cut materials and more complex machining. If you have any concerns regarding collet chucks or the points mentioned above, please feel free to consult with us.
