Therefore, it is important to choose the right tooling. The toolholder consists of two parts: machine side and tool side. The machine side is connected to a machine spindle. In most cases the type of machine side is chosen depending on the spindle type which exists in the machine. In some cases, when the machining required adapters (for example, machining with long overhang) or when purchasing a new machine, the type of machining side of tool holder is selected depending on the main type of operations, the required accuracy, and the type of workpiece.The most common spindle types or machine side tool holders:CAMFIX (ISO 26623-1)HSK (DIN 69893) Type Aexist: Type A / B / C / D / E / F / T7/24 Taper ShankBT DIN 69871 CATThe most common modular system to increase overhangsCAMFIXclamping boltCAMFIXclamping adaptationCAMFIX holderMB ConnectionO-ringclamping boltbushingclamping nut
