Er20 Er Spring Collet Chuck 0.005Mm Accuracy 0.008Mm For Cnc Milling Tool Holder Engraving Machine Spindle

Description: 1. Wear & Deformation Resistance: Made of premium 65Mn spring steel with quenching treatment reaching HRC44-48 hardness, maintains structural stability under long-term high-strength use, effectively extends service life and reduces replacement cost. 2. High Clamping Accuracy: Processed with precision grinding technique, 16-degree taper complies with DIN6499 standard with radial runout ≤0.01mm, delivers even clamping force on tools or workpieces, greatly improves processing precision and reduces defective rate. 3. Strong Reliable Clamping Force: Adopts three-section elastic slot structure, generates uniform radial deformation under axial pressure, locks tools firmly even during high-speed machining, avoids tool slipping and ensures processing safety. 4. Wide Compatibility: Covers ER20 series with clamping diameter ranging from 0.5mm to 34mm, fits all standard CNC tool holders, engraving machines, milling machines and lathes, meets diverse processing demands and saves extra procurement cost for different clamps. 5. High Efficiency Quick Change Design: Elastic clamping structure supports fast clamping and releasing operation, shortens tool change time effectively, improves overall processing efficiency for production lines. 6. Smooth Polished Surface: Precision polished metal surface reduces friction with tool holders, makes installation and disassembly easier, prevents jamming during long-term use. Specifications: Material: 65Mn Spring Steel Size: As Shown In The Picture Color: Silver Application: Suitable for CNC machining centers, milling machines, lathes, drilling machines, tapping machines, engraving machines, used for tool clamping and workpiece fixing in boring, milling, drilling, tapping, grinding and precision carving processing Quantity: 1 piece Note: 1.
