Friction fusion type drilling technology is also called as hot melt drilling, flow drilling, thermal drilling, thermal friction drilling, etc. This flow drilling is chipless process, no waste; Thread length is several times of material thickness, very high process reliability. Our CNC friction drilling and tapping machine adopts same technology with high quality carbide drilling head and tapping head, forms internal flange holes for stainless steel underfloor water distributor manifolds. Drilling cycle time for 1/2" hole: 4~5 seconds. Tapping cycle time for 1/2" hole: 7 seconds.
