Casting sleeve processing examples
This time, I will introduce the machining of cast iron sleeves. Our company specializes in the machining of cast iron, which is often disliked by other companies. Among these, we frequently receive requests for the production of medium-sized sleeve-shaped products. This time, we are showcasing products up to the polishing stage, but we can also carry out polishing processes. Generally, lead machining on a lathe places a heavy load on the machine, so it cannot be done without a rigid machine. Additionally, since the product in this case is long, machining will be done using a steady rest. Our company excels in lathe-shaped machining such as cast iron, steady rests, and lead machining. In machining, we focus on process shortening through jigs and deep hole machining. We can accommodate depths of approximately 30 to 35 times the diameter for φ8.5 (depending on the shape size).
Fire compartmentation and fire spread line compliance.
The "Smooth Sleeve" has been adapted for fire compartments and fire spread lines. The "Smooth Sleeve" is a piping assembly board for water heaters that reduces the labor involved in core drilling and caulking when multiple pipes and cables penetrate ALC and RC. Core drilling (φ160) is completed in one location, resulting in a neat appearance after installation. The sealing packing adheres closely to various pipes and cables to prevent water ingress, eliminating the need for caulking and contributing to improved construction efficiency. 【Features】 ■ The penetration processing for multiple pipes and cables, such as water and electricity, is completed with a single core drill. ■ Adopts a highly water-resistant double-structured sealing packing. ■ In the unlikely event that water enters, it drains through the internal drainage path. ■ The guide packing fits into the sleeve hole, making positioning easy. *For more details, please refer to the materials or our company website. Feel free to contact us with any inquiries.
All machining from turning of shafts and flanges to grinding is possible.

Improvement in the discharge of cutting chips. Here are examples of how high-precision and beautiful products can now be processed!
Here are some examples of improvements related to high-precision processing of fine holes. Processing fine holes is effective with nozzle through, but the NC lathe could not provide nozzle through coolant with just a change of M code. Therefore, we purchased a sleeve for nozzle through. By blocking the normal discharge holes and supplying cutting oil from the back side using a copper pipe, we ensured that the cutting oil reached the back of the hole from the cutting edge of the boring bar. As a result, the discharge of chips was improved, and we were able to process high-precision and clean products. ★ Case Study ■ Subject: High-precision processing of fine holes ■ Strategy: Utilization of functions ■ Effect: Prevented operational mistakes; reduced working time Our company is engaged in research and development prototypes to small-lot production across a wide range of fields, including medical devices, aerospace, optics, electronics, and office automation. We produce high-precision and high-quality items daily, such as "acceleration tubes" made of oxygen-free copper on a micron order and "thruster injectors" used in artificial satellites. #AccelerationTube #ThrusterInjector *For more details, please refer to the PDF document or feel free to contact us.

Contributing to further efficiency! Reducing equipment costs by replacing embossed sleeves.
The "Sleeve Jacket Roll" is a groundbreaking product that allows for the replacement of only the outer cylinder (sleeve) of the embossing roll during the changeover of production varieties such as non-woven fabrics. There is no need to completely replace the expensive embossing rolls for each pattern, which helps reduce equipment costs. By introducing this sleeve roll along with various embossing sleeves, equipment costs are lowered, contributing to the production of a wide variety of materials and improving production efficiency. 【Features】 ■ Excellent cost performance ■ Quick replacement operation For more details, please refer to the catalog or feel free to contact us.
Parts used in precision measuring instruments! We have a monthly shipment record of 5,000 units and can accommodate up to 100,000 units.
The sleeve (hard turning process) is a component that guides the outer part of the section where the measuring terminal moves. A cylindrical tolerance of 2 microns for the inner diameter is required to enable precise measurements. The material is stainless steel 440C, hardened to HRC60 or above through vacuum hardening. After heat treatment, the outer diameter is first finished using centerless grinding. With an outer diameter of 7mm and a dimensional tolerance of 12 microns, coaxiality between the inner and outer diameters requires 4 microns, so the inner diameter is processed based on the outer diameter after finishing it. The inner diameter of 5mm is turned with a precision of 10 microns and a cylindricality of 4 microns, and in the final finishing, honing is performed to achieve a precision of 4 microns and a cylindricality of 2 microns. 【Features】 ■ A component that guides the outer part of the section where the measuring terminal moves ■ Made of stainless steel 440C, hardened to HRC60 or above through vacuum hardening ■ Outer diameter of 7mm with a dimensional tolerance of 12 microns ■ Inner diameter of 5mm turned with a precision of 10 microns and a cylindricality of 4 microns ■ Monthly production record of 5,000 units, capable of handling up to 100,000 units *For more details, please refer to the PDF document or feel free to contact us.
