![[Equipment Introduction] Cylindrical Grinding Machine (Okamoto OGM)](https://image.mono.ipros.com/public/product/image/7ac/2000354195/IPROS5360024293084114554.jpg?w=280&h=280)
We offer a variety of grinding stones, including diamond, borazon, and WA, capable of accommodating many materials.
The secret of Tokiwa Seiko's technology, which responds to diversifying needs, lies in its wide range of in-house equipment. In cylindrical grinding, we offer various grinding wheels such as diamond, borazon, and WA, enabling us to accommodate many materials. For powder metallurgy mold punches, it is common to finish the outer diameter with a mirror surface. Typically, two processes are required: finishing the dimensions with cylindrical grinding and then polishing to achieve a mirror finish. However, at Tokiwa Seiko, we have developed a method that allows us to finish the dimensions and achieve a mirror surface simultaneously during the cylindrical grinding process, enhancing efficiency. If you have specific requests such as "I only want to rely on this equipment for processing," we can also perform pinpoint processing using available equipment. Please contact us, and we will provide updates on the machine's operational status. *For more details, please refer to the PDF or feel free to contact us.

During grinding, the workpiece is held by magnetic force! Special techniques are required for grinding non-magnetic materials such as stainless steel.
A grinding machine is a machine that finishes by rotating an abrasive wheel. Its features include the ability to process hard materials (such as those after hardening) that cannot be cut, and it can easily process items where achieving precision through cutting is difficult (on the micron level). Grinding not only meets dimensional tolerances and surface roughness but also varies the type of grinding machine based on the shape being processed, fulfilling geometric tolerances and other purposes. Broadly speaking, grinding machines are classified into three types: "flat," "outer diameter," and "inner diameter." Similar to lathes, the machines used differ based on purpose and application, so it is necessary to choose the appropriate one.

The advantage is that the operations are continuous, with no time for attaching and detaching products or operating machines, resulting in high productivity!
Centerless grinding machines, also known as coreless grinding machines, are capable of grinding the outer shape of round objects without the need for chucks. The advantages of centerless grinding include "no need for centering, making it manageable even for inexperienced operators," and "less grinding allowance, resulting in less wear on the grinding wheel." Although the precision may be somewhat inferior compared to cylindrical grinding machines, their high productivity and ability to grind elongated objects make them very useful.

High-precision machining is possible! Introducing "Trumbas Cut" and "Plunge Cut"!
A cylindrical grinding machine is a type of machine tool that can grind the outer shape (cylinder) and taper of round objects. There are two main grinding methods for cylindrical grinding machines, which are largely categorized based on the relationship between the grinding wheel and the movement of the workpiece. In centerless grinding, processing cannot be done if there are grooves, but with a cylindrical grinding machine, processing can be performed even if there are grooves, as it involves chucking. For more detailed information, please refer to the related links. *For more details, please check the PDF materials or feel free to contact us.*
