High Precision Wear Resistance Customizable Slot Milling Insert for Mechanical and Aerospace Applications

Special groove milling series 680202/38 7.6 12.2 with mid-range coating material HYKH06. Customizable insert options available.

Slot milling inserts are precision tool components specifically engineered for milling various groove-shaped structures including keyways, right-angled grooves, T-shaped grooves, and irregular grooves. Installed on milling cutter bodies and synchronized with machine tool rotation and feeding motions, these inserts achieve precise groove processing. Widely utilized across machinery manufacturing, automotive, mold making, aerospace, and other industrial fields, they serve as core tools for groove-type machining operations.

• General Machining: Processing of keyways and right-angled grooves on shaft-type and disc-type parts, such as motor shaft keyways and gear hub grooves. Commonly employs three-edged or two-edged cemented carbide slot milling inserts.
• Mold Manufacturing: Processing of cooling grooves, ejector pin grooves, and parting surface grooves in mold cavities. Requires high-precision slot milling inserts to ensure dimensional consistency and superior surface finish. Triangular slot milling inserts are ideal for narrow, deep cooling grooves.
• Automotive Manufacturing: Processing of oil passage grooves in engine blocks, sealing grooves in transmission housings, and wheel hub mounting grooves. Relies on high-efficiency coated cemented carbide slot milling inserts for mass production, balancing efficiency with extended tool life.
• Aerospace: Processing of irregular grooves and weight-reducing grooves on titanium alloy and superalloy structural components. Demands special AlCrN-coated cemented carbide or ceramic slot milling inserts to withstand high-temperature cutting environments.
• Electronics & Precision Instruments: Processing of micro-grooves and shallow grooves on small components such as sensor housings and connectors. Typically utilizes small-sized triangular or single-edged slot milling inserts to ensure high precision and minimal surface roughness.
