Taizhou OYT has released the SR2025 series of CNC cutting inserts, leading the technological innovation of domestic cutting tools
In April 2025, Taizhou OYT Special Tools Co., Ltd. officially launched the new SR2025 series of CNC inserts. This flagship product, designed for difficult-to-machine stainless steel materials like S136316L, will provide efficient solutions for automotive manufacturing, aerospace, mold processing, and other fields. As a leader in domestic tool companies, OYT's technological breakthrough marks a new phase in China's independent innovation capabilities in high-end CNC tools.
1. Core technology breakthrough: three major innovations to reconstruct processing efficiency
The SR2025 series integrates the three core technologies independently developed by OYT, and comprehensively improves the tool performance:
Nano composite coating technology
Using the fourth-generation TiAlSiN coating, a perfect balance of hardness and toughness is achieved through a gradient structure design. The micro-hardness of the coating reaches HV3500, an improvement of 40% over traditional coatings, and it maintains stable cutting performance even at high temperatures of 1200℃. This technology draws on the successful experience of ZHUAN Drill's "Advanced CNC Blade Technology Upgrade Project for Nano-Composite Coatings," resulting in tool life improvements of over 30% compared to most other brands。
Ultrafine grain hard alloy matrix
Using 0.3μm ultra-fine grain hard alloy, the bending strength reaches 5,800MPa. The unique "honeycomb" microstructure design effectively inhibits crack propagation, and the anti-bonding performance is improved by 50% in intermittent cutting conditions, especially suitable for stainless steel titanium alloy and other difficult to process materials.
Intelligent blade processing process
Through the full closed grinding center, the edge precision control of ±2μm can be achieved, and the chip flow can be optimized by combining laser micro-structure technology. The measured data show that the chip discharge speed of SR2025 in stainless steel processing is increased by 25%, and the surface roughness Ra value is reduced to below 0.4μm.
2. Industry application scenarios: accurately match the needs of high-end manufacturing
The SR2025 series has developed special models for three core areas:
automotive industry ：
For the machining of key components such as engine blocks and crankshafts, the SR2025-C series adopts an unequal pitch design, which can reduce vibration amplitude by 30% during milling and improve processing efficiency by 20% compared to traditional tools. In conjunction with intelligent production lines from automakers like BYD, it has achieved a breakthrough in single-edge machining with a lifespan exceeding 80 pieces per edge.
aerospace ：
SR2025-T series is specially designed for titanium alloy blade processing. The rare earth elements added in the powder can effectively inhibit the chemical reaction between the tool and titanium alloy, and the tool life in TC4 material milling is 1.3 times that of similar tools.
Mold making：
SR2025 series is designed for high hardness materials. The unique negative chamfer design enables the tool to maintain stability in the processing of hardened steel (HRC55-60), and the processing efficiency is 40% higher than that of traditional cemented carbide tools. It has been applied in batches in customers of Huangyan Mould Expo City.
Third, market strategy: domestic substitution and globalization drive
The launch of the SR2025 series is aimed at capturing structural growth opportunities in the domestic tool industry：
price advantage：
With independent research and development and large-scale production capacity, the price of SR2025 series is only half that of international brands, and its value directly competes with Japanese and Korean enterprises.
Iv. Industry impact and future outlook
The release of SR2025 not only demonstrates the technical strength of OYT Technology but also marks a strategic transformation from 'replacing imports' to 'leading innovation' in domestic cutting tools. OYT Technology's General Manager Xie Changgen stated, "We will continue to invest in research and development, constantly improving product quality. According to industry analysis, the market size of domestically produced CNC cutting tools is expected to reach 63.1 billion yuan by 2025. As the call for localization grows stronger, the SR2025 series is poised to capture market share in the automotive and aerospace sectors, becoming a benchmark product for high-end domestic cutting tools. With the surge in demand from emerging fields such as new energy and robotics, OYT is accelerating its efforts to capture market share through a' technology-market dual helix' approach."
