Chongde ER High Precision Spring Collet Runout is 0.0003" A new process quenching treatment for collets, which has a decisive influence on product accuracy, service life and stability. Quenching is a high-frequency aging treatment added to the heat treatment, -384.8â?? degrees cryogenic treatment, these are not reflected in the appearance, but have a decisive impact on the service life and stability of the product. Processing technology, full-line CNC internal hole grinding machine, compared with the products processed by ordinary internal hole grinding machine, the inner hole straightness is better, the finish is better. Er Collet 5 ER11 Spring Collet 1) Runout of our ER collet are within 0.005mm-0.008mmm. 2) ER8, ER11, ER16, ER20, ER25, ER32, ER40 and ER50 collet. 3) Made of high quality steel: JIS-SUJ2. 4) Packing:Inner packing is plastic or paper box, the outer packing is cartons. 5) We normally supply three kinds of accuracy: first accuracy 0.005mm, and second accuracy 0.008mm. The highest accuracy is 0.005mm. 6) Inspection: 100% collet inspection. The production process of ER Collet Cryogenic treatment 1) -196â??, and ultra long cryogenic treatment make the nearly all retained austenite change to martensite. 2) The precipitated nano carbide particles increase the hardness and toughness of the material. 3) Remove the internal stress of the residual material. 4) After cryogenic treatment , the wear resistance of products is significantly improved, and the accuracy and service life of repeat clamping can be increased by about 50%.

ER collet is the most widely used clamping system in the world used for a variety of machining applications including boring, milling, reaming, tapping and grinding. The advantages of ER Type Collets are: High polished finish for extra accuracy and long life, especially when clamped in ER chucks Superior clamping strength Fits all brands of ER holders The benefits of ER Type Collets are: Quality: Product consistency and worldwide acceptance Material: Durability and increased collet life Wide Clamping Range: Less collet inventory necessary Broad Product Range: Versatility for a variety of applications Clamping Length: Higher clamping power and improved T. I. R. Matched Tooling System for Best Fit: Compatibility of the whole system results in maximum precision, balance and tool life Precision: Increased tool life and part quality. According the amonut of ordering goods.

Characteristic: Unique design is mechanically sealed by virtue of the rear slots terminating prior to the annular groove, completely blocking the path of coolant flow to the front of the collet. When using thru-coolant cutting tools, these collets ensure 100% coolant delivery to the tip of the cutting tool. Range of use. Boring, milling, drilling, tapping, engraving, cnc, spindle machine, and other processing. Collets er and er-up: Assembling collet Insert groove of collet into eccentric ring of the clamping nut at the mark on the bottom of the nut. Push collet in the direction of the arrow until it clicks in place. Screw nut with collet onto toolholder. We recommend tightening the nut with atorque wrench. Disassembly collet After the nut is unscrewed from the toolholder, press on the face of the collet while simultaneously pushing sideways on the back of the collet opposite the mark until it disengages from the clamping nut.
