Prospine provides one-stop solutions for all your magnet product and metal processing needs.
Prospine Inc. (formerly Shoei Koki) has been manufacturing and processing precision machine parts in Osaki City, Miyagi Prefecture, since its founding in 1978.
We particularly excel in mold parts and press parts processing. We flexibly accommodate customer requests regarding processing methods and delivery times.
Fast and beautiful machining
Cuts metal using water pressure
To achieve precision at the 1/1000mm level, we are fully equipped with various measuring instruments for rigorous quality control. Here we introduce the equipment we use to inspect processed parts from various angles and deliver highly precise products.
A type of measuring microscope that measures fine dimensions (length, angle) of machine parts (including precision parts), tools, gauges, etc.
A machine that projects a magnified image of the object onto a screen and measures its contours and points as coordinate values
Measures surfaces in 3D without contact. Height, angle, radius, and other measurements at multiple points can be captured instantly in a single shot. Surface roughness and waviness can also be calculated, enabling numerical quality control.
We process parts making the most of a variety of processing equipment, including machining centers, milling machines (NC and general-purpose), waterjet cutting machines, and drilling machines. For details on our equipment, please see our equipment list.
