Example: 5702VZD14CA020R58-2 5702 = Stellram Product Family • Check spindle condition: V = Screw fixation Runout Z = Insert shape (parallelogram) Balancing D = ISO insert clearance (D = 15°) Profiling & Pocketing Mills Clamping of the attachment in traction 14 = Insert edge length (mm) Marking and cleanliness C = Plain straight shank (No flats) • Check that the tool is suitable for the required use. A = Through the tool coolant 020 = Cutting diameter (mm) • Inserts must be locked positively in the pocket and R = Right hand tool secured using the torx screw provided. The screw must 58 = Reach of tool in mm be torqued to the correct value as indicated in our charts -2 = Maximum value of the insert radius in 1/10mm increments on the steel product pages A248 & A250 . For security use a new screw each time. This tool must only be used for the following applications: Face milling, shoulder milling, slotting and pocketing. • Check the balancing of the – assembled tool – cutter body, inserts and attachment. • Before start up, note the maximum RPM engraved on Cylindrical shanks & HSK shanks (special): 5702VZD14 and 5720VZ16 are the tool or in our technical documents. The maximum RPM is linked to a precise balancing value. designed and balanced to G6.3 at 30,000 rpm for diameters 50mm and below. Diameters larger then 50mm are balanced to G6.3 at 24,000 rpm. Cylindrical • Ensure that the field of application of the tool shown in shank tools mounted in a shrink fit holder or any other mill chuck holder + inserts our technical documents and technological parameters + screws must be re-inspected for balance by the end user when exceeding 8,000 is observed: rpm. End user must balance the assembly to a G6.3 value minimum. ae (mm) width of cut, lateral engagement (radial) Shell Mills and Modular Heads: 5720VZ16 Shell Mills and Modular Heads are ap (mm) Axial depth of cut not balanced.

To this product: avoid making modular heads weaker, limit these operations by avoiding high rpm. • Non observance of the above instructions For each new modular head added to the same extension, re-balance the • Machine without casing assembly.
