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

Index: SW03.06.010.030.05HL

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

Design Advantages and Technical Properties:

• Chip Breaker Design: Shaped blades crush chips into small pieces, reducing cutting resistance and preventing clogging of chip channels.
• Special Sintered Carbide (VHM) Monolith: A dedicated hard alloy grade with increased wear resistance ensures a long tool life.
• Polished Chip Flutes: The mirrored surface of the channels facilitates smooth chip removal and prevents sticking and melting of PVC on the blades.
• Upward Chip Evacuation (Positive): Right-hand chip channel lifts chips upwards, maintaining cleanliness in the machining area.
• 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.
• Protective Coating HC: High-performance AlTiN coating with a hardness of 3350 HV (0.05) and high thermal resistance protects the blade from wear and significantly reduces chip sticking when machining aluminium and composites.  

Intended Use and Application Range:

The tool is intended for milling operations on PVC profile sections during jointing without grooves and in shaped configurations on GRAF SYNERGY® machining centres.

Used in the processing of materials such as polyvinyl chloride (PVC) profiles and plastics used in window and door joinery.
