Product Detailed Description
The TCMT16T304-MX YS6125 turning insert is a high-precision carbide cutting tool engineered for fine finishing and semi-finishing operations, where ultra-smooth surface finishes and tight dimensional tolerances are non-negotiable. Its model parameters encode specialized performance for precision-focused industries:
- TCMT: ISO-standard triangular (60° included angle) insert, ideal for high-accuracy turning (external turning, facing, light shoulder turning) and access to narrow part features.
- 16T304: Dimensions - 16.51mm inscribed circle diameter, 3.97mm thickness, 0.4mm nose radius (critical for achieving Ra ≤0.4μm surface finishes and sharp part corners).
- MX: Versatile chipbreaker geometry, optimized for low-to-medium feed rates (0.1-0.25mm/rev) to control fine chips in finishing passes.
- YS6125: Premium micrograin carbide grade with TiAlN coating, balancing exceptional edge sharpness (for fine cuts) and wear resistance (for extended tool life in steel machining).
Designed for CNC precision lathes and Swiss-type machines, this insert excels in automotive electronics, medical device, and precision instrument manufacturing-where small, high-tolerance parts demand reliable, consistent cutting performance.
Key Application Scenarios
- Automotive Precision Components: Perfect for finishing alloy steel parts like 4140 transmission gear shafts (with 0.5-2mm step shoulders), 30CrMnSi fuel injectors, and aluminum alloy sensor housings. The 0.4mm nose radius ensures burr-free edges and mirror-like surface finishes (Ra ≤0.6μm), meeting automotive OEM quality standards (e.g., ISO 8062 H7 tolerance).
- Stainless Steel Medical Parts: Efficiently machines 316L stainless steel components such as surgical tool shafts, catheter connectors, and diagnostic equipment housings. The YS6125 grade's low cobalt content (8%) minimizes material contamination, while the MX chipbreaker prevents fine stainless steel chips from adhering to workpiece surfaces (critical for biocompatible parts).
- Electronic Device Components: Suitable for brass (H62) and aluminum alloy (6063) parts like smartphone charging port connectors, PCB mounting pins, and micro-motor shafts. The insert's precision ground edges (±0.005mm tolerance) ensure consistent part dimensions across high-volume production (10,000+ parts per shift).
- Precision Instrument Gears: Reliable for finishing small carbon steel (S45C) and alloy steel (20CrMnTi) gears in watches, meters, and robotics. The 60° triangular design enables precise tooth profile turning, reducing post-machining grinding time by 30%.
Core Advantages
- 0.4mm Nose Radius for Fine Finishes: The small, precision-ground nose radius delivers ultra-smooth surface finishes (Ra ≤0.4μm in aluminum, Ra ≤0.6μm in steel), eliminating the need for costly post-machining processes (e.g., polishing, lapping).
- YS6125 Micrograin Carbide: Ultra-fine carbide grains (≤0.9μm) maintain edge sharpness through thousands of finishing passes, while the material's toughness resists chipping in light interrupted cuts (e.g., machining parts with small grooves). Tool life is 25% longer than standard HSS inserts in steel finishing.
- MX Chipbreaker for Fine Chips: Optimized for low feed rates, the MX geometry breaks fine, stringy chips into small, manageable pieces-preventing chip buildup on toolholders or workpiece surfaces (a common issue in precision finishing).
- TiAlN Coating for Multi-Material Use: The multi-layer coating reduces friction (coefficient ≤0.35) and withstands temperatures up to 800°C, enabling consistent performance in dry or wet cutting. It resists built-up edge (BUE) in sticky materials like aluminum and copper alloys.
- ISO Standard Compatibility: Fits all standard TCMT toolholders (e.g., SCLCR 12, SVJCR 1616H16) and integrates seamlessly with precision CNC lathes (e.g., Haas ST-10, DMG Mori NLX 2500), ensuring easy adoption into existing precision machining setups.
