Introducing a case where the adoption of a high-frequency spindle resolved difficulties in ensuring precision.
We would like to introduce a case where Seiko Instruments Inc. resolved challenges through test processing. For small parts, such as components for medical devices, where coaxiality between the inner and outer diameters is required, it is generally difficult to ensure precision using commonly employed tool clamping methods like air chucks, diaphragm chucks, and magnetic chucks. Our internal grinding machine addresses these challenges by adopting a roll spindle mechanism used in bearing processing and our self-developed high-frequency spindle. [Case Overview] ■ Issues - Difficulty in ensuring precision for small parts requiring coaxiality between the inner and outer diameters. ■ Results - Achieved automatic supply of parts via a parts feeder, automatic measurement of workpieces after processing, and automatic discharge. - Capable of responding to demands not only for processing precision and efficiency but also for overall productivity improvement. *For more details, please refer to the related links or feel free to contact us.

Introducing examples of problem-solving achieved through high-speed spindles and machining know-how cultivated over many years of experience.
We would like to introduce a case where Seiko Instruments Inc. resolved challenges through test processing. When performing internal grinding of micro-holes, the rigidity of the quill supporting the grinding wheel becomes lower, resulting in greater deflection of the quill, making it very difficult to ensure dimensional and shape accuracy. With our internal grinding machine, we can perform high-efficiency internal grinding of extremely small diameters down to a minimum of 0.3mm, thanks to our self-developed high-speed spindle with high precision and the processing know-how cultivated over many years of experience. [Case Overview] ■Challenges - Ensuring dimensional and shape accuracy ■Results - High-efficiency internal grinding of extremely small diameters down to a minimum of 0.3mm is possible. *For more details, please refer to the related links or feel free to contact us.

Shortening Cycle Time! Introducing Examples of Processing Neodymium Magnets
We would like to introduce a case study of "magnet" processing that we conducted. Our goal was to improve processing accuracy and achieve in-house production of workpieces that our customers had been outsourcing. Compared to before implementation, processing time was reduced by 65%, achieving a surface roughness of Ra 1.5μm or less and roundness of 1.5μm or less. 【Case Overview】 ■ Processing dimensions: φ4mm × 26.4mm ■ Material: Neodymium magnet ■ Features: Special material, long hole (L/D = 6.6) ■ Model: STG-3N ■ Spindle: M8H-T (Max 80,000rpm) *For more details, please refer to the related links or feel free to contact us.
![[Processing Example] Thin-Walled Workpiece CNC Internal Grinding Machine STG-6N](https://image.mono.ipros.com/public/product/image/f1f/2001044258/IPROS34561284441042999581.jpeg?w=280&h=280)
Applying the technology cultivated in mass production of precision parts to general-purpose internal grinding machines! Introducing our processing examples.
We would like to introduce our processing case that has achieved high-precision machining of thin-walled workpieces. Workpieces that require internal grinding often demand not only roundness and surface roughness but also runout (coaxiality) relative to the outer diameter. This is particularly challenging for thin-walled workpieces, where deformation due to gripping becomes an issue. To address this, we have equipped our CNC internal grinding machine STG-6N, which we manufacture and sell, with a newly developed 2-roll 1-shoe spindle, enabling high-precision machining of thin-walled workpieces. 【Case Overview】 ■Challenges - Susceptible to deformation due to gripping ■Results - Uniform wall thickness relative to the reference workpiece's outer diameter - Dramatic improvement in coaxiality of the inner diameter relative to the outer diameter after machining - Reduced deformation of the workpiece due to gripping, leading to expected improvements in roundness *For more details, please refer to the PDF document or feel free to contact us.
