A "grinding machine" is equipment used to process workpieces by pressing a high-speed rotating grinding wheel against the material to be machined. Since it processes by grinding away the surface, it takes longer to achieve the desired shape compared to cutting processes that involve cutting the material. However, because it grinds slowly and gradually, it can achieve high precision. It is commonly used in the finishing process to enhance surface accuracy after shaping the workpiece into the desired form through cutting processes. 【Features】 ■ Presses a high-speed rotating grinding wheel against the material to be processed ■ Used in the finishing process to enhance surface accuracy ■ Manual grinding machine: Small, handheld for processing materials ■ Machine grinding machine: Installed in factories such as manufacturing industries *For more details, please refer to the related links or feel free to contact us.

The grinding machine can be classified according to the purpose of processing and the shape of the material to be processed. The "surface grinding machine" is primarily equipment for performing surface grinding, and it can be used for various types of grinding depending on the direction of movement of the workpiece and the way the grinding wheel is applied. In addition, there are "internal grinding machines" for performing internal grinding, "cylindrical grinding machines" that rotate the grinding wheel in the opposite direction to the workpiece, "centerless grinding machines," and "tool grinding machines." [Types of Grinding Machines (Excerpt)] ■ Surface Grinding Machine - Achieves both high dimensional accuracy and high precision surface roughness - Capable of achieving high flatness and parallelism on both sides of the workpiece ■ Internal Grinding Machine - Standard type: Both the workpiece and the grinding wheel are rotated while the grinding wheel is moved back and forth - Planetary type: The workpiece is fixed while only the grinding wheel rotates *For more details, please refer to the related links or feel free to contact us.

A grinding machine is a piece of equipment that processes workpieces by pressing a high-speed rotating grinding wheel against the material to be machined. It is mainly used for finishing processes and machining difficult-to-cut materials, but various types of equipment and machining methods are employed depending on the workpiece and the area to be processed. Additionally, with the miniaturization and complexity of finished products, the demands on machining equipment continue to rise. This document explains the basics of grinding machines and the types of grinding machines and grinding processes. We encourage you to read it. At Seiko Instruments, we primarily handle internal grinding machines. Seiko Instruments' internal grinding machines utilize a self-developed high-frequency spindle, achieving high precision and work efficiency, especially for small-diameter hole machining, while also being space-saving. If you are considering the introduction of an internal grinding machine, please feel free to consult with Seiko Instruments. *For more details, please refer to the PDF document or feel free to contact us.

Thin-walled machining is a process that involves machining a workpiece to a thin profile while maintaining high precision. Workpieces that require internal grinding often demand not only roundness and surface roughness but also concentricity concerning the outer diameter. This is especially true for thin-walled workpieces, where deformation due to gripping becomes a challenge. Seiko Instruments has developed a highly versatile 2-roll, 1-shoe spindle, applying methods previously used for internal grinding of ball bearing components to avoid deterioration of shape accuracy caused by gripping. If you are facing issues with shape accuracy due to gripping, such as with scroll chucks, collet chucks, or mandrel chucks, please feel free to consult us. *For more details, please refer to the PDF document or feel free to contact us.*
