5-Axis CNC Perfection: DSDL Series 7075 Aluminum Disc Couplings

The DSDL Series Aluminum Single and Double Diaphragm Coupling is a masterclass in zero-backlash motion control. Machined entirely from premium 7075 aerospace-grade aluminum alloy and finished with defensive anodization, this clamp-style coupling utilizes a 5-axis CNC single-setup machining process to guarantee flawless concentricity. Paired with high-end 304 stainless steel 4-hole square disc packs, it offers maximum torsional stiffness and rapid rotational response, making it the ultimate solution for high-performance servo drives and CNC automation where aftermarket maintenance costs must be eliminated.

Core Product Advantages

• 5-Axis Single-Setup Machining: Forged with elite multi-axis CNC techniques to align all dimensions in a single operation, resulting in perfect coaxial alignment and zero rotational deviations.

• Aviation-Grade 7075 Aluminum: Features higher yield strength and lower rotational inertia than standard 6000-series aluminum, accelerating motor responsiveness under high cyclic start-stops.

• R-Angle Stress Relief Notching: The integrated clamping slot features a specialized R-type radiused edge geometry, dispersing mechanical clamping pressures to prevent localized metal fatigue or cracking.

• H7 Plug Gauge Full Verification: Every single bore is strictly subjected to a 100% manual H7 plug gauge inspection, guaranteeing standard-compliant shaft clearance and an unyielding frictional lock.

• Industrial 304 Disc Membranes: Employs heavy-duty 4-bolt square stainless steel sheets that provide zero-backlash torque transmission while offering elite anti-oxidation and rust defense.

• Ergonomic De-Burred Chamfering: All machined profiles and socket bolt counterbores feature smooth rounded radius chamfers, ensuring safety and preventing finger scratches during field installation.

• 12.9-Grade High-Tensile Hardware: Outfitted with blackened industrial-tier clamping fasteners to deliver maximum clamping friction torque without stripping hazards.
