How does the hole in the flange of the flanged pipe work?
Flange hole three methods of processing One is the use of precision casting With foundry poured out The second is to use out of the ordinary drilling machine Once every three is the use of CNC machine tool processing Is that a clamping multiple CNC drilling machine of bit sorry is I just seen when visiting the specific model I'm not sure also use ordinary drilling machine can use the rocker drill will stack up flange forming a processing will save more time
After punching a good sample, you can drill the hole directly with a twist drill. The larger diameter hole can be processed twice
The factory USES a bench drill, now manual, numerical control all have, so, you do this thing to do what?
