Precision 0.005mm ER20 Chuck Spring Collet, AAA Collet Chuck Engraving Machine CNC Spindle Lathe Tools Milling Parts 1PCModel: ER20 collet chuckAccuracy: 0.005mm AAAMaterial: 65MnER20 clamping range: 3mm-13mmWidely used: milling, drilling, tapping, engraving machine, CNC, spindle machine and other clamping tools.The package includes: 1pc of ER colletNote: Collets and milling cutters are not included and need to be purchased separately65Mn material: After heat treatment and cold drawing hardening, the strength is relatively high, and it has certain flexibility and plasticity.Heat treatment method: Effectively avoid deformation and cracking.Cryogenic treatment increases hardnessThe correct installation steps of the collet1. Put the chuck into the pressing cap, and turn it to the snap spring gently. After the eccentric part of the pressing cap is recessed into the snap spring groove, push the snap spring evenly in the direction of the arrow to install it into the pressing cap.2. Install the clamping spring with the pressing cap on the chuck body or the machine tool spindle, clean the cylindrical handle of the tool and insert it into the clamping hole. Use a wrench to tighten the pressing cap evenly until the tool is clamped. use.(Note:It is forbidden to fasten the pressing cap without a cutter installed to avoid damaging the spring)3. When changing the tool, use a wrench to loosen the clamping cap to bring out the chuck and the tool, take away the tool, push the card spring in the direction of the arrow to make it exit, and then replace the card spring with another hole diameter as required. High Precision: Achieve an impressive accuracy of 0.005mm AAA, ensuring optimal performance for your CNC and engraving tasks. Versatile Clamping Range: devised for a clamping range of 3mm to 13mm, this ER20 collet is perfect for various milling, drilling, and tapping applications. Durable Material: Made from 65Mn material, this collet undergoes heat treatment and cold drawing hardening for enhanced strength, flexibility, and plasticity. Enhanced Performance: The cryogenic treatment increases hardness, effectively reducing the risk of deformation and cracking during use. Easy Installation: Follow simple steps for correct installation, ensuring a secure fit for your tools and preventing damage to the spring during operation.
