Solving the dilemma of choosing a partner company! Document on processing achievements and selection points for processing contractors.

Solving the dilemma of choosing a partner company! Document on processing achievements and selection points for processing contractors.

[Essential for Engineers and Purchasing Agents!] A document presenting five key points to identify reliable processing companies, along with examples of "processing achievements" such as short delivery times and small-lot, diverse products!

Points to identify reliable processing contractors and problem-solving materials are content that we would like not only engineers but also ordering personnel and site managers to read. "Problems in searching for partner companies" and "Five points to identify reliable processing contractors" are surely the answers our customers are looking for in this booklet! ★ Right now, we are offering the booklet for free! 【Do you have any of these problems? (Excerpt)】 - I want to place an order, but sending materials is a hassle... - For a first-time order, they won't accept it if it's a small quantity with many varieties... - There are no standard products, and no one can process them... 【Our Strengths】 - Consistent production from materials - With just one drawing, we arrange materials and deliver satisfactory products as "finished products" - Instead of saying "we can't do it" for difficult products, we request our extensive network of partner factories to meet needs to the fullest - Reliability reflected in a high repeat rate - Stable quality regardless of whether it's prototype or mass production *For details, please contact us or refer to the catalog.

Deep hole machining <Gundrill method & BTA method>

Deep hole machining <Gundrill method & BTA method>

Processing diameter φ1mm to φ500mm, maximum processing length 10,000mm! Hole drilling with a diameter tolerance typically around H7 to H9 is possible.

Miroku Machinery also supports processing related to hole machining. With the gun drill method, we can process hole diameters from φ1 to φ35 and depths up to 4,000mm. With the BTA method, we can process hole diameters from φ15 to φ500 and depths up to 10,000mm. We have excellent diameter tolerances, cylindricity, and roundness, and by using carbide tips, we can drill holes in materials with hardness up to HRc40 to 45. 【Features】 ■ High-efficiency deep hole machining ■ Minimal bending ■ Good surface roughness ■ Good diameter tolerances, cylindricity, and roundness ■ Capable of drilling holes in high hardness materials *For more details, please refer to the PDF document or feel free to contact us.

Deep hole machining

Deep hole machining

It supports deep hole machining from φ1.5 to φ24, up to a maximum of 750mm (depending on the hole diameter).

The deep hole machining of Casttec using the latest gun drill technology can accommodate depths of up to 280mm for φ1.5, 440mm for φ2, and 750mm for φ6 (for round-shaped materials). The above refers to hole machining from one direction, not from both sides, so there will be no connecting steps in between. Additionally, for die-casting core pins, smoothing the tip of the hole to a smooth SR shape helps suppress the occurrence of cracks during use. We have processing achievements not only with SKD61, a hot work tool steel mainly used in die casting, but also with various types of steel for plastic molds, stainless steel, copper, and brass.
