There are ten questions as below, more answers we have got will be more exact and correct bond of pcd inserts, drawing or product picture will be much appreciated.
①what pcd inserts are in demand, full faced pcd inserts or tipped pcbn inserts? if tipped inserts, how many cutting edges/working tips needed?
②the work part name for machining: such as automotive engine block, cylinder head, pressure tank, gearbox etc.
③the work piece material: such as tungsten carbide, aluminum, cast aluminum, aluminum alloy, copper alloy, brass, non metals cemented, reinforced plastic, glass fiber reinforced plastic, ceramics, hard rubber, wood inorganic board etc.
④hardness or grade of the work piece material for machining? if aluminum alloy, how much silicone content included in? (Si<12% or Si>12%)
⑤turning or milling? machining method: rough machining, semi-finish machining or fine-machining?
⑥for continuous machining, light interrupted/intermittent machining or heavy interrupted/intermittent machining?
⑦what surface roughness grade Ra, is the machining process adding coolant or dry machining?
⑧if the insert plate need negative T land/chamfer or ER treated/honing? like CNMN 120408 T 0.2×20°
⑨if the insert plate need wiper, any requirements on surface finish? for obtaining better roughness than Ra 0.4 or Ra 0.6.
⑩cutting condition parameters.
cutting speed (V):= ? meter/minute (or tell us the workpiece diameter and the rotary speed)
cutting depth (ap):= ? mm (Penetration of a tool)
feeding speed (f):= ? mm/revolve (The amount of feed/feed motion) |
