Three promises to our customers

Promise 1 Fast, Precise, Cordial!
Promise 2 We can propose better plans based on the value analysis of your current plan and on our professional experiences.
Promise 3 Your orders can range from a small-sized lot to a large one.

We have specialized machines ideally suitable for machining of large work pieces.

We are sure to send our estimate to you as requested, with the details as soon as possible. We give you the estimate for the entire process including material arrangements, machining, following processes, heat-treatment, and surface processing.


We can propose better plans based on the value analysis of your current plan and on our professional experiences.

As for our proposals regarding the manufacturing or test machining of metal parts, certain important factors must be taken into consideration in re-planning: the way of the usage and that of your processing. Of course, all the proposals will be planned on the basis on your specifications.


  • You need a single piece or a small sized lot of repair part for the assembly line
  • Your offer was refused only because of the small number of your order.
  • Other companies refused your offer of only one piece.
  • You are looking for professionals that can always provide you with commercial.
  • parts at reasonable price.

An example of reducing the costs by our better plan on the basis of value analysis

We had an order of machining manufacturing parts, and the material was provided by the client who ordered it.
It was a shaft part and the material was provided in a half-processed condition; it was cut in the designed length and the center holes were already bored on both edges.

At the beginning, we took the standard process: we cut the materials with bandsaw, scribed the centers of the both edges, then bored holes on the center with the drill press lathe, and finished with lathe process.
Next, we processed key-slotting on the both sides and polishing. However, this way of machining required an extra process before polishing; it needed re-centering with lathe.

The reason for it was that the centers of both edges were often not precisely coaxial after the key-slotting process. Moving onto the next process of polishing without re-centering would cause the lack of concentricity or roundness, so we had to add the extra process of re-centering.
To solve this problem, we proposed a better plan to our client: our suggestion was to process the material with the horizontal machining center after cutting it with the bandsaw, then to bore the center holes on both of its edges and to process the external diameter of chucking parts as the first process.
By changing the process, we could omit a process of lathe before polishing.
Therefore, we could shorten the machining time, and it brought our client and ourselves a great advantage of lower cost.
The former process of re-centering was actually time-consuming and required more tasks, such as chucking and reversing of work pieces.
Moreover, we changed the way of external diameter processing of the first process; using the horizontal machining center for lathe could cut down the number of the lathing processes. These improvements finally summed up to a huge reduction of total process time.

As a result, we could provide those products almost at the same price as before.

An example the product quality improvement resulting from our proposal based on value analysis

This example is about a part of a machine that was required to have much more endurance.
It was a part of the bevel gear of steel roller, and it had such a large load that it would be extremely exhausted in a short period of time. The client requested us to improve the quality of that part.

With the previous procedure, we roughed the material with lathe and treated it with heat with 2mm allowance left as the finishing amount, then finished with lathe and gear cutting ( roughing/finishing).

However, with this way of processing, the most important part of the gear that required the machine strength was eroded through roughing, because that part had roughing process after the heat treatment .
This procedure sufficiently satisfied the efficiency, but the clients requested us to improve the products so as to make them more endurable.

We devised a better process: in the first process, we handled both roughing of lathe and gear cutting, followed the heat treatment, the finishing process of lathe and gear cutting.The new plan needed some extra tasks; we finished lathing the teeth parts after the heat treatment, and this was interrupted.

The cut was inconvenient for us. Moreover, in the finishing process of teeth parts, we needed to re-arrange the location of the roughed. Thus, extra time and labour were sometimes needed dependent on the type of machining.
Despite the necessity of the extra tasks, we were able to end up with products with the much hardened layer using the heat treatment left. We succeeded in producing parts that were extremely durable and high quality.

As a result of this improvement, we made a great success in extending the life of the “bevel gear” part to approximately twice its previous length.

Your orders can range from a small-sized lot to a large one.
Your orders can range from a single piece to a small-sized lot of 10 parts, a middle-sized lot of 100. Services for orders of a large-sized lot are also available.
We can also handle commercial mas-production orders.

  • You need a single piece or a small sized lot of repair part for the assembly line
  • Your offer was refused only because of the small number of your order.
  • Other companies refused your offer of only one piece.
  • You are looking for professionals that can always provide you with commercial.
  • parts at reasonable price.
