Characteristics

• Can be used up to tolerance class IT8 
• For tolerances up to IT11 the special model RAP with pressure controlled expansion is available 
• Processing of all metallic materials with a tensile strength of 1400 N/mm² and a maximum hardness of HRC ≤ 45 
• Attainable surface finish R_z < 1 micron (R_a = 0.1 micron)
• Machining in pushing motion with clockwise rotation
• Available with different straight shanks (optional with hollow shank for very long workpieces)
• Internal coolant-lubricant supply optional
• Parameter recommendation:
  • Max rotary speed: up to 250 m/min 
  • Max feed: 0.3 mm/rev per roller

Advantages

• Compact design for application in machines with limited workspace
• High degree of accuracy
• Short cycle time
• Diameter adjustment is easy and reproducible
• Requires minimal lubrication (oil or emulsion)
• Tool automatically contracts upon retraction, preventing damage to the roller burnished surface
• Wear parts are easy to exchange
