Processing of Special Steel

当社独自のシャフト製造技術で高精度、高い耐摩耗を実現
Special steels have various properties, harder than normal steel, have a sticky or soft. We are good at precision-lathe-processing and difficult processing special steels which other company avoids by substantial equipment and results with high processing skill.

We would be glad to accept your request totally from supply materials to finish and also processing of High Precision Thin Ring which is hard to shave thinly, preventing transformation of a ring and polynomial processing include heat treatment.

Precision-turning Process

Large lathe processing
up to diameter 2,000 and weight 15t

Possible to high-precision-process up to 2.000 by lathe. By the high strength, we'll accept at low cost from a cutting of hard to shave to thinly ring which can be demanded.

Process of a thinly ring

More than half of our products are ring-shaped or sleeve-shaped. A technical expert will do difficult process because of thinness. We will respond to processing method suitable for precision.

Process of split product

"split products" need high-precision at the inside diameter. This process can be possible just because our company has NC vertical lathe, other various kinds of machines, tools and experts who have a technical skill.

Process by general-purpose lathe

There are a lot of products which take much time and can not adjust subtly by NC lathe processing. Therefore, experts who have a technical skill adjust subtly by visual observation and process quickly for only small lot.

Processing of Special Steel

Various results of processing

For long time, we have accepted products which are hard to cut like stainless which has large coefficient of thermal expansion, super heat-resistant steel and titanium which has high affinity with tooling material. We are highly trusted by our customers through the technology backed up with experiences.

Valuation by Three-Dimensional Measuring Machine

Be realized more high-precision confidence by Three-Dimensional Measuring Machine. Possible to evaluate the comparison of measurement forms of Two-Dimensional and Three-Dimensional to CAD drawing using the newest CNC Three-Dimensional Measuring Machine made in MITSUTOYO.

Wide variety of small Lot

Usually, more than half of products which have received the orders are a small number unit of 1 ∼ 5 and it's ordered product. Please do not hesitate to ask for a small amount of order. We will process it in good faith.
