VHM Spiral Mill with Chip Breaker for PVC Profiles on GRAF SYNERGY® Machines – Upward Discharge

Index: SW03.06.010.030.05HR

Industrial spiral mill made from solid carbide (VHM) with a chip breaker and positive geometry (upward discharge of chips). Designed for efficient milling of cross-sections in PVC profiles on specialised GRAF SYNERGY® machines. The integration of the chip breaker effectively crushes the chips, reducing cutting resistance and preventing clogging of the chip spaces. The dedicated carbide grade with increased wear resistance ensures extended tool life, while the polished chip grooves prevent soft materials from sticking to the body. The tool is available in both right-hand and left-hand versions. The precisely ground shank in H6 accuracy class eliminates radial runout, protecting the machine's drive system.

Design Advantages and Technical Properties:

• Chip Breaker Design: Profiled blades crush the chips into small pieces, reducing cutting resistance and preventing clogging of the chip channels.
• Special Solid Carbide (VHM): Dedicated grade of hard alloy with increased wear resistance ensures long tool life.
• Polished Chip Grooves: Mirror-like surface of the channels facilitates free chip removal and prevents sticking and melting of PVC on the blades.
• Upward Chip Discharge (Positive): Right-hand chip channel lifts the chips upwards, keeping the machining zone clean.
• Low Shank Roughness (Ra ≤ 0.3 µm): Ground shank prevents slipping in the holder and protects the spindle cone from wear.
• Dynamic Balancing G2.5: Compliance with ISO standards enables smooth and vibration-free operation at high rotational speeds.
• HC Protective Coating: High-performance AlTiN coating with hardness of 3350 HV (0.05) and high thermal resistance protects the blade from wear and significantly reduces chip sticking during aluminium and composite machining.  

Application and Range of Use:

The tool is designed for milling cross-sections of profiles during non-groove and shaped joining of PVC carpentry on GRAF SYNERGY® machining centres.

Used for machining materials such as: polyvinyl chloride (PVC) profiles and plastics used in window and door carpentry.
