T11N/T16N/E CNC Internal Grooving Inserts

About the product

1. Insert type: T11N/T16N/E grooving inserts are flat-mount grooving inserts suitable for CNC lathes.Used for grooving and cutting operations on various materials.

2. Application areas:These CNC inserts are used for grooving and cutting operations, suitable for a variety of materials such as steel, stainless steel, cast iron, non-ferrous metals, etc.

3. Insert material: Internal grooving insert is made of carbide, which is a high hardness and wear-resistant metal material.

4. Features:These inserts are used to improve processing efficiency, have high precision and smooth surface treatment, and have long tool life and are suitable for a variety of materials.

Material & Durability

• Carbide Substrate: Crafted from high-grade cemented carbide (tungsten carbide + 6–10% cobalt binder), delivering hardness up to 92 HRA and exceptional wear resistance. This material withstands the friction and heat of grooving/cutting, even on abrasive metals like cast iron or stainless steel.

• Coating Options:

• TiAlN (Titanium Aluminum Nitride): Enhances oxidation resistance (up to 800°C) and reduces friction—ideal for steel and stainless steel machining, extending edge life by 30–50%.

• TiCN (Titanium Carbonitride): Boosts surface hardness for high-speed grooving of non-ferrous metals (aluminum, copper), minimizing built-up edge (BUE).

• Uncoated: For soft materials (e.g., low-carbon steel, brass) where coating adhesion could compromise surface finish.

Key Features

1. Flat-Mount Design for CNC Lathes
   Engineered as flat-mount grooving inserts, they fit seamlessly into standard grooving toolholders for CNC lathes. The flat seating ensures stable clamping, reducing runout to ≤0.003mm—critical for maintaining groove width accuracy (±0.01mm) across batches.
2. Multi-Material Versatility
   Optimized for grooving and cutting steel (carbon/alloy), stainless steel (304/316), cast iron (HT200/QT450), and non-ferrous metals (aluminum 6061, copper). This eliminates the need for separate inserts for different materials, simplifying inventory.
3. High Precision & Smooth Finishes
   Precision-ground cutting edges and chipbreaker grooves ensure clean, burr-free groove walls and surface finishes as fine as Ra 1.2μm. This reduces post-machining deburring time and meets tight tolerance requirements for components like bearing races or hydraulic valve slots.
4. Efficiency & Long Life
   The carbide substrate’s wear resistance extends tool life by 40–60% vs. high-speed steel (HSS) inserts. For example, when grooving 45# steel, T11N/T16N/E inserts deliver 180–250 minutes of continuous use per edge, cutting tool change downtime.

Applications

• Core Operations:

• External Grooving: Creating grooves on shafts, bolts, or cylindrical parts (e.g., automotive transmission shafts).

• Internal Grooving: Machining grooves inside housings or bores (e.g., hydraulic cylinder snap ring grooves).

• Parting/Cutting-Off: Separating workpieces from bar stock (e.g., cutting small aluminum fittings from a rod).

• Target Industries:

• Automotive: Grooving for powertrain components and chassis parts.

• Machinery: Machining precision grooves in gearboxes or bearing housings.

• Electronics: Cutting small non-ferrous parts (e.g., copper connectors).

Compatible Machines & Toolholders

• CNC Lathes: Works with all major brands (Fanuc 0i-TF, Haas ST-series, Mazak Quick Turn, Doosan Puma) and both horizontal/slant-bed models.

• Toolholders: Designed for use with flat-mount grooving toolholders (e.g., SCLCR, PCLNR series) with wedge-lock or screw clamping—ensuring secure insert retention during high-feed grooving.

Performance & Operating Parameters

• Recommended Cutting Speeds:

• Steel/Stainless Steel: 80–200 m/min.

• Cast Iron: 60–150 m/min.

• Aluminum/Non-Ferrous: 300–800 m/min.

• Feed Rates: 0.1–0.3 mm/rev (adjust based on material; lower for hard metals, higher for soft non-ferrous).

User Testimonial

Sophia Kim, CNC machinist at MetalPro Components, says: “These T11N inserts are a staple for our grooving jobs. We use them for steel shafts one day and aluminum fittings the next—no need to switch inserts. The precision is great—groove widths are consistent every time, and we rarely have to deburr. One edge lasts a full 8-hour shift on 45# steel, which saves us so much time on tool changes.”
