Collet milling arbor for saws with a cylindrical shank S20 

Index: SBA.S20.30.250

Precision milling arbor with a cylindrical shank, intended for mounting circular saw blades and saw mill cutters on CNC machining centres, point-to-point machines, and overhead spindle mills. Made of highly resistant special steel with precision-ground interface surfaces, guaranteeing excellent tool centering and operation free of vibrations and axial runout. The optimised, reduced design increases the working space between the workpiece and the machine spindle. The holder allows for efficient machining at very high feed rates and speeds of up to 20,000 RPM (for power > 15 HP), ensuring excellent edge finish quality and longer tool life.

Key technical parameters and properties:

• Cylindrical shank design: Allows for mounting in standard collets with cylindrical shank.
• Very high rotational efficiency: Designed for operation with powers above 15 HP and rotational speeds up to 20,000 revolutions per minute.
• Reduced body height: Increases free working space between the element and the spindle body.
• Excellent centering and balancing: Precision grinding of all contact elements ensures rotation without radial and axial runout.
• Replaceable clamping rings: Equipped with radial grooves for secure and stable tool fastening with a wide clamping tolerance (-0.7 mm).
• Safety recommendation: For proper and safe tightening of the fastening screws, it is recommended to use a torque screwdriver TW-006.

Application and purpose:

The tool is designed for mounting circular saw blades for formatting, cutting, and grooving on CNC machining centres, drilling-milling machines (point-to-point), and CNC routers.
