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

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.

Deep hole machining of resin

Deep hole machining of resin

Work hours can be reduced! Achieving both cost reduction and excellent finishing.

We would like to introduce our "deep hole processing for resin." We can drill holes over 200 times deeper in one go, significantly reducing work time and providing a much more profitable processing method compared to other methods, without the need to change a large number of tools. Even when drilling holes several meters deep, the surface roughness remains below 3.2S, allowing for precise finishing. 【Features】 ■ Excellent surface roughness due to the vanishing effect of the gun drill ■ Good concentricity (can also accommodate thin-walled processing) ■ Processing time is faster compared to other cutting methods ■ Good hole diameter accuracy *For more details, please download the PDF or feel free to contact us.

[Processing Example] Long-Length Trepanning Processing

[Processing Example] Long-Length Trepanning Processing

A 300mm deep hole was machined into a 5-meter long aluminum material. Trepanning was performed from both ends.

This is a photo of the trepanning process performed from both ends of the material. When trepanning is carried out, a core of material remains. Since the processing was done from both ends, a flange has formed in the central part of the core material.

[Processing Example] Counter BTA Processing of Spindle Products

[Processing Example] Counter BTA Processing of Spindle Products

After L1 and BTA, the hole diameter of the treated material will be further enlarged.

Using a head called a counter, we further enlarge the hole diameter of the material that has undergone tempering after L1 and BTA. We carry out processes such as L1, BTA → tempering → L2, BTA → stress relief → L3, BTA at the request of our customers. After the final BTA, honing may also be performed. In that case, honing will be carried out by our partner company, and honing is also very well received.
