The multi-functional NC Helix Drill from Nine9 is intended to reduce non-cutting times by conducting helical interpolation milling, ramping, slotting, counter-boring and drilling with a single tool. Just six different tools are required to drill precision holes from 13 to 65 mm diameter.
Working on an interpolation cycle, the NC Helix Drill reduces the cutting load on the spindle by ramping at an angle up to 20° whilst the sinusoidal ‘wavy edge’ insert breaks the swarf into fine chips. In addition, the drill body is available with either a cylindrical shank or as a screw fit holder that can fit most toolholder extension bars on the market. The drills are available with or without through coolant facility for rapid swarf evacuation.
Corresponding with the NC Helix Drill is an insert with two cutting edges per insert and a serrated cutting edge geometry. Produced from a K20F micro grain carbide substrate that is TiAlN coated, the tool is suitable for use material ranging from aluminium, carbon steel, low and high alloy steel, stainless steel, cast iron, nickel to titanium alloys.
Complementing the NC Helix Drill at MACH 2016 will be the Nine9 Series of deburring tools. Developed to achieve high speed and feed de-burring and countersinking on all types of machine tools from sliding head lathes through to machining centres, the Nine9 deburring range uses a single-edged TiAlN coated carbide inserts shaped in a 6-flute edge geometry.
Capable of deburring and countersinking hole diameters as small as 0.5 mm, the high precision series is also the tool of choice for processing 60 and 90° chamfers with depths from 0.1 to 1.75 mm. The high alloy steel toolholder is ground to an h6 tolerance and has a brazed carbide shank to eliminates vibration and extends insert life.
