The conditions should be adjusted as necessary according to the actual conditions of machined shape, purpose, machine used, etc. 3) If the machine rotation speed is insufficient, reduce the rotation speed and feed rate by the same ratio.
Open the catalog to page 5Cutting Conditions<Finishing condition> Work material [Note] 1) Use the appropriate coolant for the work material and machining shape. 2) This standard cutting condition table is intended as reference cutting conditions. The conditions should be adjusted as necessary according to the actual conditions of machined shape, purpose, machine used, etc. 3) If the machine rotation speed is insufficient, reduce the rotation speed and feed rate by the same ratio.
Open the catalog to page 6For stable machining, perform semi finishing to remove remaining stock in the corners. (This will make the machining amount for finishing uniform.) At this time, it is recommended that the program should be set so that the cusp height will be a constant amount. In addition, it is recommended that semi finishing should be performed with CBN end mill. < Input of diameter correction value > Make effective use of the measured outside diameter value stated on the case. For Epoch CBN High Precision Ball End Mill, the measured outside diameter value is stated on the case. Inputting the actual...
