Compression finishing VHM spiral end mill Z#liczba_ostrzy_z from the SN01 series – ideal edge quality without chipping

Index: SN01.12.035.090.12R

Industrial spiral end mill made of solid tungsten carbide (VHM) from the SN01 series with compression geometry. The tool is equipped with counter-rotating screw lines of blades, which simultaneously push chips from the upper edge down and from the lower edge up, pressing the laminate against the core of the plate. Designed for finishing machining, 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 machined material. The ground shank in accuracy class H6 minimises radial runout, ensuring smooth machining and a long spindle life.

Construction advantages and technical properties:

• Compression geometry (Positive-Negative): The combination of right-hand and left-hand spiral blades guarantees a smooth, clean edge without chipping on both the top and bottom surfaces of the plate.
• Finishing geometry of blades: Precisely ground cutting edges ensure high surface quality without the need for additional finishing machining.
• Solid tungsten carbide (VHM): The rigid monolithic construction reduces tool deflection under load and maintains dimensional precision.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards eliminates vibration at high rotational speeds.

Purpose and scope of application:

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

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