プロテクノ堺 List of Products and Services

We would like to introduce the "regrinding and repair" services offered by Protechno Sakai. Cemented carbide has excellent wear resistance, and since it experiences minimal wear even after long use, it can be restored to its original condition through regrinding. Of course, the cost and delivery time are significantly lower than manufacturing new parts. You can definitely achieve cost savings compared to repeatedly replacing slightly cheaper steel parts. Please feel free to leave it to us. 【Features】 ■ Significantly reduced cost and delivery time ■ Can be repaired by replacing layers like tatami mats *For more details, please refer to the related links or PDF materials, or feel free to contact us.

Introducing "Superior Brazing." Brazing is one method of joining metals together. It involves melting a metal with a lower melting point than the base materials (filler metal) and flowing it between two pieces of steel, then cooling and solidifying it to create the joint. Unlike conventional welding (arc welding), the base materials do not melt significantly, which is an advantage for maintaining high dimensional accuracy. [Reasons to Choose Us] ■ High precision, resulting in a long lifespan ■ Enables a more secure brazing ■ Further cost reduction through regrinding and repairs *For more details, please refer to the related links or PDF materials, or feel free to contact us.

We would like to introduce the "Precision Machining Examples" handled by Protechno Sakai. We manufacture components such as blades used for workpiece support in centerless grinding machines, front plates used as work reference surfaces in bearing manufacturing machines, and shoes used in bearing manufacturing machines. For more details, please contact us. 【Examples】 ■ Carbide brazed products - Blade ■ All carbide products - Front plate ■ Ceramic bonded products - Shoe *For more information, please refer to the related links or PDF materials, or feel free to contact us.

Let me introduce you to "super hard parts." Super hard refers to an alloy made by binding tungsten carbide powder with cobalt as a binder and sintering it. As the name suggests, it is a very hard material, possessing hardness second only to diamond and ceramics. Due to its minimal reduction in hardness at high temperatures, it exhibits particularly excellent wear resistance. Our company specializes in the manufacturing of long-lasting components using this super hard alloy. **Benefits of Super Hard Parts** - Eliminates variation in product dimensions - Improves product quality - Allows for faster cutting conditions - Reduces the frequency of part replacements, enhancing productivity *For more details, please refer to the related links or PDF materials, or feel free to contact us.*

The two major factors that cause shoe marks are "difficult-to-machine materials such as SUS" and "workpiece installation accuracy." With ProTechno Sakai's ultra-precision shoes (made of carbide, ceramic, and PCD), there is potential for improvement. They provide smooth sliding with a surface roughness of less than Ra 0.05, making it difficult for shoe marks to appear even under high loads. Additionally, the installation accuracy is improved with ultra-precision shoes made from the base, resulting in numerous cases where shoe marks have disappeared or improved. 【Features】 ■ Smooth sliding with a surface roughness of less than Ra 0.05, making it difficult for shoe marks to appear even under high loads ■ Improved installation accuracy with ultra-precision shoes made from the base ■ Numerous cases where shoe marks have disappeared or improved *For more details, please refer to the PDF document or feel free to contact us.

Our company is engaged in product development day and night to evolve minor industrial machine parts, such as front plates, which have not seen any evolution for decades, especially focusing on improving the production efficiency of tools that are particularly inefficient. With the method we propose, processing is done entirely with carbide, eliminating all the disadvantages associated with conventional front plates, resulting in a long lifespan. Additionally, the processes of "hardening" and "brazing" are no longer necessary, which reduces processing costs, so even with an all-carbide front plate, the unit price remains unchanged compared to conventional front plates. [Our Proposed Method] 01. Purchase raw materials from carbide manufacturers (no need for hardening or brazing processes due to being all-carbide) 02. Process using a surface grinding machine 03. Finish holes using an internal grinding machine *For more details, please feel free to contact us.
