VHM Compression Finishing Spiral Mill Z#liczba_ostrzy_z from the SL01 series – ideal edge quality without chipping

Index: SL01.03.023.070.06R

Industrial spiral mill made of solid sintered carbide (VHM) from the SL01 series with compression geometry. The tool is equipped with opposing screw lines of blades that simultaneously push chips from the upper edge downwards and from the lower edge upwards, pressing the laminate against the core of the board. Designed for finishing operations, cutting, jointing, and edge trimming 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 processed material. The ground shank in precision class H6 minimises radial runout, ensuring smooth machining and a long spindle life.

Design advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right and left twist blades guarantees a smooth, clean edge without tearing on both the upper and lower surfaces of the board.
• Finishing blade geometry: Precisely sharpened cutting edges ensure high surface quality without the need for additional finishing processing.
• Solid sintered carbide (VHM): Rigid monolithic construction reduces tool deflection under load and helps maintain 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 in class G2.5: Balancing according to ISO standards eliminates vibrations at high rotation speeds.

Intended use and application range:

The tool is intended for cutting, nesting technology cutting, as well as jointing and edge trimming on CNC machines.

It works perfectly in machining materials such as: soft and hard solid wood, raw and laminated MDF board, raw and laminated chipboard, as well as raw and veneered plywood.
