One JP manufacturer inquired Nine9 how to drill holes of different diameter and depth by economical and efficient way, Nine9 then recommended below NC Helix Drill holder for the project.
• Machine: CNC horizontal boring and milling machine.
• Work material: SCM440 | DIN 1.7225 for mold of Automobile bumper parts.
• Blind hole: Ø60mm; Depth: 50/100/150mm individually.
• Holder: B840112 M16-HD36-5070 (for φ50mm~φ70mm).
• Extension bar: 0-398032-300M16 (φ32mm x L300mm).
• Insert: N9MX12T308-NC5072
Ø36mm M16 screw fit type helix drill is capable to drill the hole of 50mm to 70mm. While fitting into extension bar, the drilling depth can reach to 300mm, so it is no problem to drill deep holes as requested. Finally, the customer completed the Ø60mm blind holes of 50/100/150mm individual depth just by one NC Helix Drill which save a lot of tools and money.
In addition to the great performance, the customer also noticed spindle load is approximately 5% only, and there is almost no cutting noise and resistance during the process. It is due to small cutting load of serrated cutting edge, helical interpolation and low power consumption, NC Helix Drill help to reduce the vibration during machining to protect the machine spindle and eliminate the cutting noise and spindle load.
