High-Hardness Steel End Mills: SH360 and SHM200 Series

Processing high-hardness steel (HRC45-65) demands exceptional tooling solutions. The SH360 and SHM200 series end mills are engineered to meet these challenges, offering enhanced wear resistance, extended tool life, superior surface finish, and precise dimensional accuracy.

Key Features

• Advanced Coating Technology: Hardness increased from 30 GPa to 40 GPa with oxidation resistance temperature rising from 1000°C to 1200°C.
• High-Precision Grinding: Refining surface quality, directly improving the finish of the workpiece.
• Stable Grinding Process: Guarantees high-precision products with consistent quality, enabling reliable production of micro-diameter tools.

Application Cases

Case 1: SH360 Series

• Tool Specification: SH360-S6-6-15-K / D6x15x50xd6
• Material: SKD11 (60 HRC)
• Parameters: 8000 RPM, 3000 mm/min feed rate, 6.0 mm depth of cut (Ap), 0.08 mm width of cut (Ae)
• Cooling/Tool Holder: Air cooling / Heat-shrink holder
• Outcome: After machining 60 meters, SH360 exhibited a flank wear of 0.04 mm, outperforming competitor tools with over 0.1 mm wear, indicating a performance advantage exceeding 66%.

Case 2: SHM200 Series

• Tool Specification: SHM200-BN2-3-13-K / R1.5x2.4x13
• Material: SKD11 (60 HRC)
• Parameters: 11200 RPM, 1344 mm/min feed rate, 0.04 mm depth of cut (Ap), 0.04 mm width of cut (Ae)
• Cooling/Tool Holder: Air cooling / Heat-shrink holder
• Outcome: After 120 minutes of machining, SHM200 showed a flank wear of 0.027 mm, surpassing competitor tools with 0.049 mm wear, demonstrating over double the performance.
