VHM Compression Spiral Finishing Mill Z#number_of_edges_z from the SM01 series – perfect edge quality without chipping

Index: SM01.10.022.070.10TR

Industrial spiral mill made from solid carbide (VHM) from the SM01 series with a compression geometry. The tool is equipped with opposing helical cutting edges that simultaneously push chips down from the upper edge and up from the lower edge, pressing the laminate against the core of the board. Designed for finishing, cutting, jointing and edging, as well as nesting technology cutting on CNC machining centres. The compression design eliminates the risk of chipping and tearing on both sides of the workpiece. The ground shank with H6 precision class minimizes radial runout, ensuring smooth processing and long spindle life.

Structural advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right and left twist cutting edges guarantees a smooth, clean edge without chipping on both the upper and lower surfaces of the board.
• Finishing edge geometry: Precisely ground cutting edges ensure high surface quality without the need for additional finishing operations.
• Solid carbide (VHM): The rigid monolithic construction reduces tool deflection under load and maintains dimensional precision.
• Low grip roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing class G2.5: Balancing according to ISO standards eliminates vibrations at high rotational speeds.
• Special protective TiSiN coating: Copper-coloured PVD coating, 1-4 µm thick with high microhardness of 3570 HV (HV 0.05). It exhibits excellent resistance to abrasive and thermal wear during high-temperature cutting operations, significantly extending tool life and reducing the frequency of tool changes.  

Intended use and application range:

The tool is designed for cutting, nesting technology cutting, as well as jointing and edging on CNC machines.

It performs excellently in the machining of materials such as: softwood and hardwood, raw and laminated MDF board, raw and laminated particle board, as well as raw and veneer plywood.
