AK-R-L Double-Hole with Locating Groove Series belongs to high-grade precision ground carbide insert series, specially developed for high-precision CNC turning, grooving and parting machining scenarios that require ultra-high clamping repeatability and positioning accuracy. Different from conventional single-position inserts, this series adopts a unique double-hole + locating groove composite structure, which thoroughly solves the problems of insert offset, poor repeatability and unstable clamping during high-speed and batch machining.
All AK-R-L series inserts are fully precision ground with strict dimensional tolerance control. Adopting high-purity tungsten steel carbide raw materials, the products feature sharp cutting edge, uniform wear resistance and stable mechanical performance. The standardized double-hole positioning structure realizes foolproof installation, greatly improving the consistency of batch machining size and surface finish.
Shenzhen Xinminghui Diamond Tools Co., Ltd. independently develops and produces Precision Ground Carbide Inserts, providing standardized and customized precision tooling solutions for global CNC machining manufacturers.
Dual-Hole Precision Positioning Structure
The unique double-hole matching positioning groove design realizes dual positioning restriction, completely avoiding angular deviation and displacement of the insert during high-speed cutting. It ensures micron-level repeated positioning accuracy, which is far superior to ordinary single-hole inserts, and is very suitable for high-precision batch production.
Integrated Locating Groove Design
The reserved precision locating groove cooperates with the special tool holder to achieve tight fitting and zero-gap clamping. It effectively suppresses tool vibration during cutting, reduces tool jumping and machining chatter marks, and improves the flatness and smoothness of the workpiece surface.
Full Precision Ground Cutting Edge
Adopting multi-process precision grinding technology, the cutting edge is sharp and burr-free, with consistent edge strength. The optimized edge geometric angle reduces cutting resistance, lowers machining heat, and effectively improves the finish of grooving and turning workpieces.
High Wear Resistance & Long Service Life
Made of high-density high-performance carbide substrate, with excellent hardness and impact resistance. It maintains stable cutting performance in long-term continuous machining, reduces frequent tool replacement, and improves overall production efficiency.
High Compatibility & Foolproof Installation
Standard double-hole spacing and locating groove size, compatible with matching special CNC Tool Holders. The positioning structure is clear, the installation is fast and accurate, relying on mechanical positioning to completely eliminate human installation errors.
Support Customized Precision Machining
Support customized carbide grades, cutting edge angles, groove types, dimensional tolerances and special coating treatments according to customer machining materials and process requirements, to meet personalized precision machining needs.
