AX-FPS – new performance horizons

[ 3 ] Products Cutting data calculator ToolExpert® Services Application Know-How Since FRAISA has measured the power and torque requirements of the AX-FPS tools, the application data in ToolExpert can be optimally positioned. FRAISA – Your technology partner for milling processes Key factors: Machine spindle and machine environment When milling aluminum, the machine tool is all too often the limiting factor. This is due to the: • r educed spindle torque at high speeds • e xisting axial spindle preload and the spindle interface • c ooling lubrication and maximum coolant pressure • t ool throats and the stability of the chucking • active spindle power • reliable chip removal Spindle torque Spindle power The torque of a machine spindle decreases significantly as the speed increases. As aluminum is machined in the very highest speed range (n ACT ), the active torque in the operational area (M ACT ) is usually crucial with respect to the spindle’s perfor- mance. Maximum profitabilty thanks the comprehensive range of products, application know-how, supplementary services and cutting data. See for yourself! One aspect that is often not taken into account but is very relevant is the bearing pretensioning of the spindle. This is why the axial tensile force must be kept as low as possible in order not to damage the spindle.
