R Tools for cylindrical bores

Through bores; diameters 201 – 450 mm
Blind bores; diameters 201 – 450 

Characteristics

• Can be used up to tolerance class IT8
• Processing of all metallic materials with a tensile strength of up to 1400 N/mm2 and a maximum hardness of HRC = 45
• Attainable surface finish Rz < 1 micron (Ra = 0.2 micron)
• Can be used on CNC turning, drilling or milling machines and machining centers or on conventional machine tools.
• Machining direction thrust with clockwise rotation
• For machining bores with large-size circular grooves or cross holes special shaped burnishing rollers are available to provide unproblematic withdrawal of the tool.

• Short primary processing time
• Convenient adjustment of diameter in 1 micron stages
• Only nominal lubrication required (oil or emulsion)
• Automatic release for tool withdrawal avoids damage to the burnished surface
• Simple replacement of wear parts
