Gundrilling is also referred to as deep hole drilling, which is a process of producing deep, straight holes in various materials. If you would like to know more about this process, then the succeeding paragraphs will feed your mind with the information it needs. The main reason why gundrilling was developed is to drill gun barrels, but now, the common use of this process is for manufacturing armament. Other industries include plastic injection molds, components of diesel and fuel, engines, gas and oil exploration and energy. This only implies that gundrilling is a very important process that makes different industries keep going.
Gun Drilling VS BTA Drilling
Although gun drilling is a very common type of task, it is commonly confused with BTA drilling. Bear in mind that the former greatly differs from the latter due to the chip removal and coolant entry. Gundrills introduce the coolant through a hole that is within the equipment, and the removal of chip occurs through the groove that is outside the equipment. In case of BTA drilling, there is a fluid enter through a specialized mechanism around the equipment, while the chips are emptied through the drill. It is said that BTA drilling is more efficient than gundrilling around a hole having 50mm diameter.
Gundrill Tool
The tool used in gun drilling is a gun drill tool, which completely differs from a usual twist drill by its exceptional head geometry. It is commonly straight fluted and allows a compressed air or liquid coolant to smoothly flow through the drill’s body out to the cutting face. The holes that it can drill are drillable into several materials, which include wood, plastics and metal. The cooling is designed to perform two functions such as to keep the cutting edge lubricated and cool and to help in removing excess chips.
But how does a gundrill tool work? With the guide pads, the hole is burnished while drilling, thus allowing the hole to maintain its straightness. When the burnishing task has already been done, a round hole with an exact diameter will be created.
A hole that is deeper than 20:1 calls for a heavy duty machine to achieve the highest process reliability and productivity. Lots of gundrilling services have different gundrill tools in order to live up to the clients’ expectations.
Gundrilling Procedure Specifications
There are different types of holes. They are as follows: Cross Cavity Holes, Waterblast/E.D.M. Starter Holes, Concentric Holes, Flat-bottom Holes, Ball-end Holes, Angle Holes, Intersecting Holes, Blind Holes and Thru Holes. There is no doubt that gundrilling is the right process for an array of drilling depths and diameters. Even the deepest holes and holes with small diameter make use of gundrilling with explicit requirements in order to sustain precision and straightness.
Diameters: If the material requires a hole that has a 1-3mm diameter, drilling it is possible by using the right equipment. Materials that require holes with diameters 3mm-25mm and 25mm-50mm can also be drilled with a common gundrill tool. However, if gundrilling services are tasked to gundrill a material with a hole diameter of 50-75mm, that is possible but will be less productive than BTA gundrilling.
Depths: If a material requires a hole with 5:1 depth, the gun services provider will make use of a common twist drill. If 10:1 is the required hole depth of a material, a high performance and heavy duty twist drill with a through-tool coolant will be utilized. For materials requiring 20:1 hole depth, a special gundrilling tool with a through-coolant will be used. Materials that require 100:1 hole depth should be grilled with gundrill tools on a specialized machine for gundrilling. If 200:1 is the required hole depth of a certain material, gundrilling service will make use of gundrill tools on heavy duty machines for gundrilling. 400:1 is considered the deepest hole depth. If a material requires this, then a tremendous drilling range with proprietary equipment will be used.
What is great with the gundrilling tool is that it can be used by gundrilling services providers in different materials such as wood, teflon, nylon, carbon steel, satellite, stainless, high nickel alloys, Rene 43, waspalloy, hastalloy, monel, inconel, tantalum, molybdenum, bronze, brass, copper, beryllium copper, magnesium, aluminum and titanium. It can also be used in industries such as subsea, plating, gas or oil exploration, military, medical, manufacturing, mold, automotive, agriculture, and aerospace.
