From Trial Manufacture to a Mass Production

Enhance the accuracy of your precision parts? Need custom orders to develop new products? With the technical expertise obtained by processing various machining, Murakami Seiki perform the ultra-precision cutting process.
First, please contact with us! Especially if you are interested in the ultra-precision cutting including lathe, milling or three-dimensional machining.
We can provide a trial manufacture, small quantity from one lot, or a mass production.
In addition, we are able to assemble machineries which are designed to assemble high precision manufacturing parts. Being able to perform all the processes, we believe that, makes it possible to reduce costs and shorten the delivery date. We may be able to improve the quality of our workpieces as well.


Examples of ultra-precision cutting process


Example 1. Milling sus304 with flatness and parallelism of 3μm

Milling sus304 with flatness and parallelism of 3μm Uses : Semiconductor producing equipment parts
Size : 30×100 (mm)
Materials : sus304 (stainless steel)
Precision : Flatness, parallelism of 3μm
Machining : Milling
Characteristic of the process : We perform 0.3mm-drilling on stainless steel by milling.

Example 2. Cutting large-sized metal molds and parts

Cutting large-sized metal molds and parts Uses : Processing of the metal mold
Size : 500×700×300 (mm)
Materials : SKD-61 (hot dies steel)
Machining : Three-dimensional processing
We can also process cutting of large-sized products such as metal mold. Curved-surface machining and three-dimensional machining are available as well.

Example 3. Cuttings of complex materials

Cuttings of complex materials Uses : Manufacturing a metal mold (when processing EDM)
Size : 200×200×400 (350) (mm)
Materials : Graphite
Precision : 3μm
Machining : Three-dimensional processing
Characteristic of the process : Graphite (allotrope of carbon) has a variety of characteristics and are known for the superior characteristic to metals such as copper and iron. However, because it is easy to crack, high-speed machining and microscopic cutting techniques are required to process this material. With our technical skills, we can provide a processing to complex materials which are difficult to machine.
