CR push type collet chuck is mainly suitable for NC/CNC l𝔉athe for machining bar. CR collet chuck disassemble the cover and change spring collet quickly which can Improve t👍he efficiency and versatility of the lathe.
The installation of CR 💃collet chuck is the same as through hole power chuck and can be replaced with each other.
Good 🎐precision, fast speed, high rigidity and𝕴 long durability.
The bar can be fed in from bar feeder and through the collet chuck🦩 hole which can I🍰mprove the processing efficiency of the lathe.
Customers can choose a suitable spring෴ collet according to the ba𒁃r shape (round, square, hexagonal) and size.
