The SCA three-side cutter arbor represents a specialized tool holding solution designed for precision milling operations in CNC machining environments. Manufactured from 20CrMnTi alloy steel and heat-treated to achieve surface hardness of HRC56-58, this arbor provides reliable performance for side milling and grooving applications. The arbor utilizes a self-tightening mechanism that automatically increases clamping torque during spindle rotation, ensuring secure tool retention during high-speed operations up to 10,000 RPM.

Available in multiple diameter specifications including SCA22, SCA27, and SCA32, with shank lengths of 90mm, 120mm, and 150mm, these arbors are compatible with standard BT40 and BT50 tool holder systems commonly used in industrial machining centers.

Self-Tightening Clamping System: The arbor incorporates a rotational self-locking mechanism where spindle rotation generates increased clamping force, preventing tool loosening during operation. This design eliminates the need for frequent retightening and maintains consistent tool positioning throughout extended machining cycles.

Precision Grinding Process: Internal and external surfaces are ground using imported grinding stones, ensuring dimensional accuracy and surface finish quality. This meticulous grinding process contributes to the arbor's ability to maintain the specified ≤0.005mm tolerance.

Durability Engineering: The differential hardness profile—combining a wear-resistant hardened surface with a tougher core—provides impact resistance while maintaining cutting edge support. The 0.8mm carburizing depth creates a durable wear layer without compromising core toughness.

In CNC machining operations, the SCA three-side cutter arbor enables accurate side milling and slotting applications where dimensional accuracy directly impacts part quality. The arbor's ≤0.005mm precision tolerance supports tight tolerance machining requirements common in automotive components, mold making, and precision mechanical parts production.

Inventory Versatility: The comprehensive specification range allows distributors to serve diverse customer requirements with a single product line, simplifying inventory management while addressing multiple application needs.

Reliability in Production Environments: The self-tightening mechanism and robust construction reduce downtime associated with tool loosening or premature wear, supporting continuous production schedules valued by manufacturing facilities.

Compatibility Standards: Conformance to BT40 and BT50 standards ensures integration with existing machining centers, eliminating compatibility concerns and facilitating straightforward adoption.

Technical Support Value: For distributors serving end-users, the well-documented specifications and clear application guidelines facilitate technical sales support and customer consultation.
