Clamp Type Knurling Tool Holder is a precision-engineered tool used in metalworking, primarily for creating knurled patterns on cylindrical workpieces. Knurling is a process that impresses a series of straight, angled, or crossed lines onto a surface to produce a textured pattern. This enhances grip, improves aesthetics, and can also serve as a decorative or functional feature on handles, knobs, and machine components. The clamp-type design ensures firm and stable holding of the knurling wheels during operation.
It consists of a robust body, adjustable clamping arms, and high-quality hardened steel wheels mounted on pins or axles. The clamping mechanism securely grips the knurling wheels and maintains uniform pressure on both sides of the workpiece, minimizing deflection and ensuring a consistent pattern. This design is especially beneficial compared to the bump-type knurling tool, as it reduces stress on the lathe spindle and workpiece by distributing the load evenly.
Clamp-type knurling tool holders are versatile and suitable for both manual and CNC lathes. They can produce various knurl patterns such as straight, diamond, or diagonal by simply changing the knurling wheels. The holder allows precise adjustment of pressure and alignment, resulting in accurate, clean, and repeatable patterns even on tough materials. Constructed from durable alloy steel with a corrosion-resistant finish, the clamp-type knurling tool holder offers long service life and reliable performance under demanding shop conditions.
It is available in different sizes and configurations to suit a range of lathe machines and knurling requirements. In summary, the Clamp Type Knurling Tool Holder provides a stable, efficient, and user-friendly solution for producing high-quality knurled surfaces, ensuring both functional and aesthetic enhancement of machined components.
