Component Specifications

Definition
The arbor shaft is a critical rotating component in the lower arbor assembly of woodworking machinery, designed to securely hold and drive cutting tools such as saw blades, router bits, or milling cutters. It transmits rotational power from the motor to the cutting tool while maintaining precise alignment and minimal runout for accurate material processing.
Working Principle
The arbor shaft operates on rotational mechanics, converting motor torque into cutting force. It maintains tool positioning through precision bearings and clamping mechanisms, ensuring stable rotation at specified speeds while withstanding axial and radial loads during material engagement.
Materials
Typically manufactured from alloy steel (e.g., AISI 4140 or 4340) with heat treatment (hardening and tempering) to achieve Rockwell C 40-45 hardness. High-precision applications may use case-hardened steel or stainless steel for corrosion resistance.
Technical Parameters
  • Taper ISO 30/40 or CAT 40
  • Length 300-800 mm
  • Max RPM 6000-10000
  • Diameter 25-50 mm
  • Load Capacity Radial: 500-2000 N, Axial: 200-800 N
  • Runout Tolerance <0.01 mm
Standards
ISO 9400, DIN 69871, ANSI B5.50
