Brief introduction
ER COLLETcnc machine tool systerm, also known as spring collet, is mounted on a drill \ milling machine, drilling and milling chuck, its function is to clamp drill cutter or knife. Er flexible collet is currently the most used. Its stable performance, high accuracy by the majority of manufacturers trust. All products are precision grinding, in line with the German DIN 6499 specifications precision manufacturing.
1) Runout of our ER collet are within 0.005mm-0.015mmm
2) ER8, ER11, ER16, ER20, ER25, ER32, ER40 and ER50 collet
3) Made of high quality steel:65Mn
4) Packing:inner packing is plastic or paper box,the outer packing is cartons.
5) We normally supply two kinds of accuracy: first accuracy 0.008mm,second accuracy 0.015mm. The highest accuracy is 0.005mm.
