When the cutting width, depth, or overhang length is large, set water soluble coolant. Vc and fz to the lower recommended values and check the machine power · When cutting an interrupted surface or a casted skin, the feed per tooth (fz) and vibration.should be reduced to the lower recommended value shown in the abovetable. G CAUTIONARY POINTS WHEN USING HJ INSERTS HJ type inserts are designed for high feed machining. TungRec 07 type HJ inserts Please note the following when using HJ inserts:1. The shape of HJ insert differs from that of other inserts (MJ,Standard conditionsAJ).However the same insert pocket can be used. H 2. When using HJ inserts, all the inserts on the cutter body 1.0 must be HJ type. Do not use other types of inserts (MJ and AJ 0.8 types) with HJ inserts on the same cutter body.3. When using CAD/CAM, please program it as a radius cutter. 0.6The table below shows the corner R when programming and I the uncut area (t). 0.4 4. With HJ inserts, the tool diameter increases by 0.6 mm Steel Stainless over the diameter DC shown in the table.
