Product Introduction

Grade (Material Composition)

Crafted from premium tungsten carbide (WC) substrates with a high cobalt (Co) binder content (5-12%, depending on grade), our inserts are fortified with multi-layered PVD (Physical Vapor Deposition) or CVD (Chemical Vapor Deposition) coatings. The coating systems include:

TiN (Titanium Nitride)

Enhances surface hardness (up to 2,400 HV) and reduces friction, ideal for low to medium speed cutting of non-ferrous metals.

TiCN (Titanium Carbonitride)

Offers superior wear resistance and toughness, suitable for alloy steels and cast irons.

AlTiN (Aluminum Titanium Nitride)

Delivers high-temperature stability (up to 800°C) and oxidation resistance, perfect for high-speed machining of hardened steels and stainless steels.

Multi-layer Combinations

Customizable coating stacks (e.g., TiN/TiCN/AlTiN) to balance wear resistance, lubricity, and thermal shock resistance for mixed-material applications.

Chipbreaker Design

Our inserts feature precision-engineered chipbreakers tailored to control chip flow, prevent built-up edge (BUE), and ensure safe, efficient chip evacuation:

Universal Chipbreakers (e.g., "CN" Series)

Designed for versatility across a range of materials (mild steel, cast iron, aluminum) and cutting speeds, producing short, manageable chips.

High-Feed Chipbreakers (e.g., "TN" Series)

Optimized for high-feed rates in roughing operations, reducing cycle times while minimizing tool stress.

Finishing Chipbreakers (e.g., "WN" Series)

Features a sharp cutting edge and smooth rake face to achieve superior surface finishes (Ra ≤ 0.8 μm) in finishing passes.

Heavy-Duty Chipbreakers (e.g., "DN" Series)

Reinforced geometry to handle interrupted cuts and tough materials like high-alloy steels and heat-resistant superalloys (HRSAs).

Cutting Conditions

Our inserts are engineered to perform reliably across diverse parameters, with recommended ranges:

Cutting Speed (Vc)

50-300 m/min (depending on material and coating; e.g., 100-200 m/min for carbon steel with TiCN coating, 150-300 m/min for aluminum with TiN coating).

Feed Rate (f)

0.1-0.5 mm/rev (0.1-0.2 mm/rev for finishing, 0.3-0.5 mm/rev for roughing).

Depth of Cut (ap)

0.5-5 mm (up to 10 mm for heavy-duty grades in steel machining).

Coolant

Compatible with flood cooling, minimum quantity lubrication (MQL), or dry machining (with AlTiN coatings for high-temperature stability).

Features & Applications

Key Features

Exceptional Wear Resistance

Multi-layer coatings and high-density carbide substrates extend tool life by 30-50% compared to uncoated inserts, reducing tool change frequency and downtime.

High Thermal Stability

Advanced coatings withstand extreme heat generated during high-speed cutting, preventing thermal degradation and maintaining cutting edge integrity.

Versatile Performance

Available in a wide range of grades and chipbreakers, ensuring optimal results across materials from soft aluminum to hardened steel (up to 50 HRC) and HRSAs.

Precision Machining

Tight tolerances on edge geometry (±0.01 mm) and surface finish guarantee consistent part quality, reducing post-machining finishing work.

Cost-Effective

Longer tool life, faster cutting speeds, and reduced waste translate to lower per-part machining costs.

Applications

Our carbide coated turning inserts excel in:

Automotive Industry: Machining engine components (crankshafts, camshafts), transmission parts, and brake discs (materials: carbon steel, alloy steel, cast iron).

Aerospace & Defense: Turning turbine blades, landing gear components, and structural parts (materials: titanium alloys, Inconel, stainless steel).

General Engineering: Fabricating shafts, bushings, and flanges from mild steel, copper alloys, and aluminum.

Oil & Gas: Machining drill bits, valves, and pipelines (materials: high-strength steel, duplex stainless steel).

Medical Equipment: Producing precision parts from titanium and medical-grade stainless steel with strict surface finish requirements.

FAQ

Q1: How do I select the right grade for my material?

A: For non-ferrous metals (aluminum, copper), choose TiN-coated grades for low friction. For carbon steel and cast iron, TiCN offers a balance of wear resistance and toughness. For hardened steels (≥40 HRC) or high-temperature alloys, AlTiN-coated grades are recommended.

Q2: Can these inserts be used for both roughing and finishing?

A: Yes. Select "CN" or "TN" series chipbreakers for roughing (high feed, deep cuts) and "WN" series for finishing (low feed, shallow cuts) to achieve optimal results.

Q3: What causes insert chipping, and how can it be prevented?

A: Chipping is often due to excessive feed rates, interrupted cuts, or improper coolant use. To prevent it, reduce feed rate, ensure stable workholding, use a heavier-duty grade for interrupted cuts, and maintain adequate coolant flow.

Q4: How long do the inserts last?

A: Tool life varies by material, cutting conditions, and grade. Typically, they last 2-5 times longer than uncoated carbide inserts-e.g., 800-1,200 parts per insert when machining carbon steel at 150 m/min.

Q5: Are custom sizes or coatings available?

A: Yes, we offer custom solutions, including non-standard geometries, specialized coatings (e.g., diamond-like carbon for non-ferrous), and tailor-made chipbreakers for unique applications. Contact our technical team for details.
