BT ER spring chuck tool holder

The TOOL HOLDER shank, intermediate connecting rod and tool can be assembled outside the machine tool and then loaded into the tool library of the machining center. According to the different ways of clamping tool, the Tool Holder can be divided into side-fixed end mill tool holder, spring chuck tool holder, heat-shrinkable tool holder, plane milling tool holder, powerful tool holder, etc. The Spring Collet Chuck tool holder includes a spring chuck for clamping and positioning the tool. Spring chuck BT Tool Holder has better tool clamping and higher precision tool positioning ability. There are three main types of spring chucks: ER type, DA type (double angle type) and TG type (single angle type or small taper type). A Spring Collet chuck is usually only suitable for a tool of one size. The clamping range of ER type chuck is large, but its taper is small and its elasticity is large, which requires high precision of matching. Double-angle chucks can be used to clamp various types of cutters, while single-angle chucks are specially used in situations where a greater clamping force is required on the cutters. Most machining centers use spring chuck tool holder.
