This precision collet flange base is a core clamping and mounting component customized for industrial automation transmission systems, servo motor output shaft connections and precision instrument positioning mechanisms. With an integrated elastic jaw structure, it undertakes precise clamping, torque transmission and flange-type mounting fixation of shaft parts, perfectly adapting to industrial working conditions with high speed and high repeated positioning accuracy. It is widely used in automated production line transmission modules, servo motor couplings, medical testing instrument positioning mechanisms and other scenarios, providing reliable rigid connection and positioning guarantee for shaft transmission.

Core Material: 6061-T6 Aluminum Alloy (industry-standard high-precision machining aluminum alloy, adapting to the elastic clamping and structural strength requirements of this part)

Key Performance:

• Tensile strength ≥310MPa, yield strength ≥276MPa, combining excellent elastic toughness and fatigue resistance, ensuring long-term stability of clamping force
• Density is only 2.7g/cm³, greatly reducing the inertial load of the rotating mechanism while ensuring structural rigidity, adapting to high-speed working conditions
• Natural corrosion resistance, can adapt to conventional industrial environments without additional coating, fully complying with RoHS and REACH environmental protection standards
• Extremely strong dimensional stability, no creep or deformation during long-term clamping use, ensuring the consistency of repeated positioning accuracy

This part adopts 5-axis linkage CNC turn-mill composite machining process, integrally cutting and forming from a solid aluminum bar, completely avoiding the hidden danger of structural strength caused by welding/splicing.

• Core processes: precision milling of elastic jaws, high-precision drilling/tapping of flange plate, radial positioning hole machining of shaft body, precision turning of end face
• Auxiliary processes: high-gloss contour chamfering, deburring, surface sandblasting/brushing treatment, ensuring no sharp edges and stress concentration on the elastic jaws
• Full CNC programming realizes one-time clamping forming, ensuring the coaxiality and clamping accuracy of the elastic jaws, meeting high repeated positioning requirements

Machining Accuracy:

• Dimensional tolerance: ±0.01mm, strictly matching the clamping clearance requirements of shaft parts
• Geometric tolerance: coaxiality of elastic jaws ≤0.015mm, flatness of flange plate ≤0.02mm
• Surface roughness: Ra≤1.6μm, smooth and burr-free clamping surface of elastic jaws, improving clamping stability

Usage Requirements:

• Adapt to a wide temperature working environment of -20℃~80℃, can withstand high speed ≥8000rpm and torque transmission ±30N·m
• No elastic fatigue or clamping looseness during long-term use, ensuring the repeated positioning accuracy of shaft transmission ≤0.01mm
• The clamping surface needs to be kept clean to avoid impurities affecting clamping force and positioning accuracy

With heat treatment, adopting solution treatment + artificial aging (T6 state) process.

• Core purpose: eliminate processing internal stress, optimize the balance between elasticity and strength of the material, enhance fatigue resistance, avoid plastic deformation of the elastic jaws after long-term use, and ensure long-term stability of clamping accuracy.

Natural color sandblasting/brushing treatment, retaining the original metallic texture of aluminum alloy.

• Process advantages: improve surface wear resistance and scratch resistance, enhance the friction and anti-slip property of the clamping surface, optimize the appearance texture, facilitate visual inspection and assembly positioning inside the equipment, fully meet environmental protection requirements, and can be used directly without additional coating.

Implement a full-process closed-loop quality control system, strictly complying with ISO9001 quality standards:

• Raw material incoming: spectral material inspection to ensure alloy composition and mechanical performance meet standards
• Processing process: 100% geometric tolerance inspection, real-time monitoring of elastic jaw coaxiality and clamping accuracy
• Final product inspection: appearance defect inspection, clamping force test, torque transmission test, full dimensional inspection, traceable inspection report for each batch
• Pre-delivery: cleanliness inspection to ensure no iron chips and impurities in the elastic jaws and threaded holes, meeting precision assembly requirements
