Methods for Drilling Tapper Holes on Large Diameter Fragile Parts
Drilling tapper holes on large diameter fragile parts can present a great challenge to machinists. These types of parts are typically used in components where their strength is essential to their purpose and need to be maintained in order to keep the overall integrity of the product intact. As such, machinists must be sure to employ a method that can ensure that the hole is drilled properly and without causing any additional strain to the part. There are several methods for drilling tapper holes in these fragile parts and the best is dependent on the part in question.
The first method for drilling tapper holes on large diameter fragile parts involves the use of a press fit drill. This type of drill is designed to be inserted into the part without the need for additional force. Instead, the press fit drill creates a uniform, clean, and precise hole in the part by applying a consistent pressure on the part itself. This type of drill is ideal for small diameter parts as the pressure applied can be easily controlled and the holes do not produce any additional strain to the part beyond the small amount of pressure applies.
The second method for drilling tapper holes on large diameter fragile parts is to use an annular cutter. This type of drill is specially designed for making holes in fragile parts and can easily be used on larger diameters. The annular cutter consists of a single circular body with multiple cutting teeth arranged around the outside. Once inserted into the part, the drill will create a perfect, clean, circular hole in the part. The annular cutter is also advantageous because it can be used to drill holes in parts of varying materials, including aluminum, brass, steel, and even some hard plastics.
The third method for drilling tapper holes on large diameter fragile parts is to use a reamer. This type of tool is specifically designed to create a controlled and precise hole in the part. The reamer is inserted into the part and rotated while slowly advancing so as to cut the edges of the hole. The reamer creates a perfect, clean, and accurate hole due to its close tolerances. The reamer is an ideal tool for making holes in larger parts as it can create a consistent result without putting any additional strain on the part.
The fourth and final method for drilling tapper holes on large diameter fragile parts is using a polymer hole punch. This type of punch is made of a flexible rubber-like material and is inserted into the part and then expands to create a perfectly round hole in the part. The hole punch is ideal for delicate parts as the expansion of the polymer does not create any additional strain on the part. Furthermore, the hole punch is capable of producing holes of varying sizes as the punch is adjustable and can easily be scaled to fit any given part.
No matter which method is employed when drilling tapper holes on large diameter fragile parts, all machinists must be sure to take the necessary precautions to ensure that the part is not damaged and that the desired result is achieved. By taking the proper precautions and selecting the most suitable method for the part, machinists can ensure that they are able to achieve the desired result and maintain the overall integrity of the part.
