Product Overview
The A-MCLNR/L 95° Turning Tool Holder is engineered for high-precision external turning and chamfering operations in CNC lathes. Featuring a rigid, dual-support structure with a 95° main cutting edge angle, this tool holder delivers exceptional stability during heavy-duty machining of shafts, stepped components, and precision grooves. Unlike conventional holders, the A-MCLNR series combines optimized clamping geometry with anti-vibration design to minimize deflection and ensure consistent dimensional accuracy across long production runs.
Technical Key Features
- High-Rigidity Alloy Steel Body: Forged from 42CrMo alloy steel and heat-treated to HRC 48–50, providing superior strength and fatigue resistance under continuous loading.
- Precision Insert Pocket Design: The 95° angled pocket ensures full contact with CN1204 inserts, reducing chatter and enhancing tool life.
- Dual-Support Clamping System: Reinforced clamp plate and center pin configuration distribute clamping force evenly, preventing insert rotation or misalignment.
- Optimized Chip Flow Path: The angled head design promotes efficient chip evacuation, minimizing built-up edge and thermal stress on the cutting edge.
- Anti-Corrosion Surface Finish: Nickel-plated or black oxide coating resists wear and corrosion in coolant-rich environments, extending service life.
Material Application Range
This tool holder excels across a broad range of materials:
- P (Steel): Carbon steel, alloy steel, and low-alloy steels – ideal for interrupted cuts and high-feed applications.
- M (Stainless Steel): 304, 316 grades – enhanced heat dissipation prevents galling and improves surface finish.
- K (Cast Iron): Grey and ductile iron – excellent wear resistance due to high hardness and durability.
Why Choose A-MCLNR/L for Your Workshop?
In modern CNC manufacturing, tool reliability directly impacts productivity. The A-MCLNR/L enables rapid insert changes without repositioning the toolholder, preserving machine calibration and reducing setup time. Its compatibility with standard ISO CN-type inserts ensures cost-effective operation while maintaining high-performance standards. Designed for both general turning and precision finishing, it’s an essential addition to any high-volume machining facility.
