[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.
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.
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.
Drilling/deep hole processing of electromagnetic soft iron (such as ELCH). High-efficiency production is possible.
■ In cutting processing, we have a proven track record of mass production of high-speed, high-precision parts. - We often receive orders for high-precision parts, particularly made from electromagnetic soft iron (such as ELCH) and stainless steel. ■ We can manufacture at suitable processing factories both domestically and internationally, having processing facilities not only in Japan but also in Vietnam and Myanmar. By selecting the processing location according to specifications, we can achieve favorable conditions for cost, delivery time, and production quantity. *For more details, please download the PDF or feel free to contact us.*
![[Processing Example] Long-Length Trepanning Processing](https://image.mono.ipros.com/public/product/image/6ef/2000661534/IPROS20468755723563942253.jpeg?w=280&h=280)
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](https://image.mono.ipros.com/public/product/image/7a9/2000662359/IPROS90077744135621780907.jpeg?w=280&h=280)
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.

There is a proven track record of drilling through holes in sharp leads (Φ0.5)! By devising a method to secure the workpiece, we can achieve strict precision! *Aluminum, stainless steel, etc.
At You Corporation, we handle small diameter and deep hole machining. Small diameter holes are more prone to breakage due to the thinness of the cutting tools, but our company addresses this with the technology and experience we have cultivated over many years. Additionally, we tackle the challenge of "difficulty in achieving coaxiality due to tool deflection in long holes" by innovating the workpiece fixation method, allowing us to meet stringent precision requirements. You can also trust us with machining difficult materials such as aluminum, stainless steel, titanium, Inconel, Kovar, and Super Invar. We are also capable of resin cutting for materials like ABS, PC, and POM at our own factory! 【Features】 ■ Proven track record of drilling through holes in sharp cores (Φ0.5) ■ Addressed with technology and experience cultivated over many years ■ Achieving strict precision by innovating workpiece fixation methods ■ Capable of machining difficult materials #SmallDiameter #DeepHoleMachining #SmallDiameterHoles #LongHoles #CuttingTools #Deflection #Coaxiality #Aluminum #StainlessSteel #Titanium #Inconel #Kovar #SuperInvar #ABS #PC #POM *For more details, please refer to the PDF document or feel free to contact us.

Shortest half-day estimate / Deep hole processing of stainless steel (φ2mm × L150mm)
<Material> Stainless Steel / SUS303 <Processing> Lathe Processing / Deep Hole Processing <Size> Small Diameter φ2mm × W150mm Although it is not visible in the photo, deep hole processing has been applied, and the inside is through-holes. Deep hole processing is done using tools like gun drills, but if ultra-small diameter deep holes are required, electrical discharge machining is used. Even in cases where processing is spread across multiple locations, our company can handle it all in one place. We also accept orders for the production of parts requiring fine processing, such as inspection device components and medical device parts, starting from single-item processing, so please feel free to consult or request us. Other processing achievements are listed in the various "Processed Parts Achievement Catalogs" available for download via the [PDF Download] link below.
