Aluminum is known as a material that distorts easily during processing because on the one hand it features good cutting ability, while on the other it is easily damaged and has a high thermal expansion coefficient.

Accordingly, by making use of the specialized characteristics of aluminum, we conduct machining in a way that controls distortion by carefully selecting the appropriate cutting conditions.

Levels of tolerance of 1% or less in terms of parallelism, flatness, angularity and dimensional precision cannot be achieved by depending on the precision of the machine alone. However, they can be achieved by placing a priority on the technological capabilities of skilled operators such as experience and know-how.

The photo on the right shows a table part for an inspection device. The dimensions are 180 (D) x 214 (W) x 381 (L) mm and the material is A5052. This product, which features top section parallelism of 1/100, rear side angularity of 1/100 and dimensional tolerance of 2/100, provides an overall demonstration of our technical capabilities.

At our factory, which specializes in aluminum machining and small lot production of many kinds of items, we manufacture a long list of aluminum parts using techniques ranging from 0.3mm small-diameter boring and 5/1,000mm tolerance boring to very large hole boring.

Also, as we emphasize in our ISO9001 quality policy, we keep to the agreed delivery time at all costs. Thoroughgoing delivery control and quality control are naturally linked to reducing costs, and we are in the process of constructing a system to assure that both are maintained

We urge you to see for yourself the products made by Nakata, which is unusual in being a Japanese precision parts manufacturer that specializes in aluminum machining.
