QF 270

Product catalog summary
Product Overview: The QF 270 is a unit designed for machining the tooth sides of PCD-tipped circular saw blades using rotary electro-erosion. It is manufactured by VOLLMER WERKE Maschinenfabrik GmbH.
Technical Specifications:
  • Circular Saw Blades: Outer diameter ranges from 100 to 840 mm, with specific ranges for robots ND2 and ND3. Bore diameter starts from 10 mm, with a maximum blade thickness of 14 mm. Cutting width is up to 16 mm, with a tooth pitch from 6 to 120 mm. Erosion path length is up to 12 mm, with hook angles from -15° to +25° and tangential clearance angles up to +6°.
  • Rotary Electrode: Maximum outer diameter is 127 mm, with a minimum worn diameter of 67 mm. Bore diameter is 32 mm, and height is 10 mm.
  • Rotary Electrode Drive: Rotational speed during erosion is 80 to 700 rpm, and during dressing is 300 to 1600 rpm. The dielectric pump delivery rate is 60 l/min, with a tank capacity of approximately 140 l. The connected load is 4.0 KW/5.0 kVA.
  • Dimensions and Weight: The machine dimensions are 2295 mm x 1405 mm x 2050 mm, with an approximate weight of 3,300 kg.
Applications: The machine is suitable for machining circular saw blades, cutting tools, and special-purpose tools.
Features: The QF 270 includes the VOLLMER PMC system with multiprocessor control and CNC-controlled axes for various adjustments and positioning, including hook angle, rotary electrode infeed, erosion path, tooth feed, tangential angle, and saw blade positioning.
