5/20 · It is worth noting that the chips produced by the twist drill aluminum and Q235 steel are spiral. The gun drill is a straight edge cutter with no spiral flutes, so the chips it produces are mostly sheet-like. In this way, the chips are short, the chip removal is easy, the knife bar is not wound, and the hole wall of the part is not scratched.

Gundrilling is a deep hole drilling process that uses a long, thin cutting tool to produce holes in metal at high depth-to-diameter ratios. Gun drilling is effective in diameters from 1 - 50. A gundrill tool differs from a conventional twist drill by its unique head geometry; a standard gundrill has a single effective cutting edge that

6/19 · 2. Choose correct drilling speed. Because drilling at a high speed will encourage heat build up it is important to monitor drilling speed and drill slower. Recommended drilling speed for aluminium varies between 200 and 300 rpm. 3. Reduced pressure Applying excessive pressure is another way to increase heat build up and therefore should be avoided.

Gun drilling is primarily used to drill deep holes beyond what is possible with conventional machinery and tooling such as twist drills, by using high pressure coolant for clean chip exhaust, even at extreme depths.

To do this, the drill must be placed on a handrail at an angle of about 45 ° and pressed with its back to the edge of the circle, without touching the cutting edge. On the lintel, two small notches up to 1/10 of the drill diameter are formed, which act as lead-in and centering edges.

Gundrilling Advantages Building our expertise since the 1970's, Carlson has drilled practically every metal alloy in all industries. The gundrilling process offers a few key advantages including much smaller hole sizes (2.0″ down to 0.055″), more parts to production hour, tight tolerances and more.

7/25 · The super fast way is a kenametal deep hole coolant through drill that takes about 17 seconds but costs around $400. It doesn't like drilling through interrupted cuts, and we have a few parts that will have 1 - 3 intersecting holes. You definately need through spindle coolant for this to work. We have 1000 PSI to play with.

1. choose the right type of drill bit for drilling aluminum in order to clear the chips effectively 2. reduce the speed of drilling to reduce the temperature, hence aluminum welding 3. use the

Deep Hole Drilling . Deep hole drilling was first developed for the manufacturing of firearms, hence the name gundrilling. Originally a time-consuming and expensive process, technological advances have made it a highly efficient manufacturing process utilized in all metal cutting industries, including automotive, aircraft, aerospace, construction, medical, tool and die, petrol chemical

Thanks to its newly developed geometry it meets the very challenging conditions of drilling a deep hole perfectly and is an ideal alternative to a gundrill.

Gun drilling can be done, with limited performance, on common CNC machines. Holes with a depth-to-diameter ratio of 20:1 or greater generally require dedicated equipment to achieve the highest productivity and process reliability, and can reach extreme ratios of 400:1 or greater. Gun Drilling vs BTA Drilling
