ファインテック List of Products and Services

Our company offers "rotary grinding." Rotary grinding is a flat grinding method where the workpiece is set on a rotating table. The rotating table pulls the workpiece using magnetic force, and it is ground with a grinding wheel from above. By performing rotary grinding after heat treatment, it becomes possible to carry out additional processing immediately after delivery, leading to time savings, so we highly recommend it. 【Features】 ■ Suitable for grinding workpieces with a large surface area ■ Excellent for mass production as it can process multiple items at once ■ Can grind both workpieces before hardening and those after hardening *For more details, please refer to the PDF document or feel free to contact us.

• Wafer processing/polishing equipment

We would like to introduce the heat treatment technology "Deoxidation Treatment" of Fine Tech Co., Ltd. This technology performs heat treatment using a reducing gas or inert gas atmosphere furnace. It allows for heat treatment without oxidizing the metal surface. While the brightness is inferior to that of vacuum treatment, it is widely used for various components. Our company primarily adopts this technology for molds made of SK materials and HMD materials, as well as for tools and machine parts. 【Applicable Materials and Material Standards】 ■ Carbon Steel (e.g., S45C) ■ Alloy Steel (e.g., SCM435, SK3) *For more details, please refer to the PDF document or feel free to contact us.

• Surface treatment contract service

Our company has been providing various heat treatment and surface treatment services, primarily focusing on vacuum heat treatment, to mold manufacturers and metal processing manufacturers. Heat treatment and surface treatment are physical and chemical control processes that change the microstructural characteristics of metals and alloys to impart properties such as hardness, strength, and heat resistance. As specialists in heat treatment and surface treatment, we will continue to meet the stringent demands of our customers. 【Business Activities】 ■ Metal heat treatment processing ■ Metal surface treatment processing ■ Polishing processing ■ Parts manufacturing *For more details, please refer to the PDF materials or feel free to contact us.

• Processing Contract
• Other metal materials

We would like to introduce our "HV8." In stainless steel with a high chromium content, chromium carbides precipitate at the grain boundaries around 600 to 700°C. Since oil cooling can cool nearly 10 times faster than gas cooling, it suppresses the precipitation of these chromium carbides and does not compromise corrosion resistance. 【Benefits】 ■ Increases hardness ■ Suppresses the precipitation of chromium carbides ■ Appropriate heat treatment temperature *For more details, please refer to the PDF document or feel free to contact us.

• Vacuum forming machine

We would like to introduce our "HV9." Equipped with the remote monitoring and control system "Vacuprof" via remote and cloud, as well as the cloud server-compatible predictive maintenance system "PdMetrics." The use of CC composite carbon fiber reinforced composite materials improves radiation efficiency, and the high insulation structure with four layers of graphite felt allows for efficient heating and cooling. 【Features】 ■ Closed cooling system - The cooling water circulates in a closed loop, preventing corrosion of the furnace body and achieving energy savings through pump control. ■ Inverter control of cooling fan - The cooling fan is controlled by an inverter under vacuum conditions, achieving energy savings. *For more details, please refer to the PDF materials or feel free to contact us.

• Vacuum Equipment

We have been providing various heating processes centered around vacuum heat treatment to mold manufacturers and parts manufacturers. Leveraging this experience, we decided to enter the heat treatment processing of aircraft components in 2012, and in 2015, we introduced a vacuum heat treatment furnace compliant with JISQ9100 and AMS standards. We fully utilize vacuum heat treatment to assist you with heat treatment processes that require traceability and heat treatment standards for special materials. 【Features】 ■ High-frequency hardening ■ Gas nitriding, gas soft nitriding, ion nitriding, tuftriding ■ Hard chrome plating ■ Thermal spraying, buildup ■ Rotary polishing *For more details, please download the materials or contact us.

• Surface treatment contract service

【Adoption of Salt Martensite Quenching Method】 Alloy tool steels such as SKS and SK3 have better machinability compared to die steels, but they face challenges with deformation due to hardening. We have adopted the salt martensite quenching method as a low-distortion treatment that can also be applied to thin plates and cutting tools. If you need heat treatment in the Kansai region, especially in Osaka, please feel free to contact us! 【Features】 ■ Uses press tempering ■ Sub-zero treatment is also possible ■ Minimizes distortion *For more details, please download the PDF or contact us.

• Surface treatment contract service

Since our establishment, we have specialized in the heat treatment of die steel for metal press molds, effectively controlling the heating and cooling processes to accommodate various shapes. We offer vacuum hardening that minimizes distortion in complex three-dimensional automotive molds while maximizing the material's properties. Additionally, our vacuum heat treatment furnace can manage the temperature distribution inside the furnace with extremely high precision, making it ideal for heat treatment of precision parts. Please feel free to contact us if you have any requests. If you need heat treatment in Osaka, the Kansai region, or the Kinki region, do not hesitate to reach out! 【Features】 ■ Minimal distortion ■ Achieves traceable heat treatment ■ Supports everything from large molds to precision parts ■ Capable of handling small lots (starting from one piece) ■ Short delivery times *For more details, please download the PDF or feel free to contact us.
