Used deep hole drills are drilling machines designed to make deep and precision holes in various workpieces. There are generally three types of deep hole drills: rifling machines, gundrill machines, and oil hole saw machines.
Rifling deep hole drill machine:
The rifling drill machine is used to cut parallel holes of uniform diameter to the required depth in a workpiece. The gundot machineworks on a similar principle. However, the gundot machine drill works on a different principle. The gundrut machine creates a single hole by using a rotating solid metal rod with an internal cooling passage and a cutting edge along its length. The oil hole saw machine cuts non-parallel holes of different diameters.
Gundrill deep hole drill machine:
The gundrill deep hole drill machine creates a single hole of uniform diameter and length in a workpiece. It creates a hole by using a hollow drill with a single cutting edge. Once the gundrill deep hole drill machine creates a hole through the workpiece, it allows coolant to pass through the newly formed hole and up the gundrill, thereby preventing the workpiece from overheating.
Deep hole boring machine:
This deep hole drill machine is used to cut precisely sized holes, internal profiles, and grooves. It can also be used to tap holes and perform other operations. Deep hole boring machines are generally large CNC machines and can be used to create holes of up to 2000 mm in diameter and 8000 mm in depth. The machine operates by using a single or multiple carbide insert cutting tools. Deep hole boring machines can be horizontal or vertical.
Specifications of used deep hole drilling machines vary depending on the type, model, and brand.
In addition to the above important specifications, other details like the size and weight of deep hole drills may also be necessary. The size and weight are crucial to understanding the dimensional characteristics of a deep hole drill. Some deep hole drills are small and portable, so users can carry them easily. Others are large and heavy-duty for industrial applications.
Maintaining a deep hole drill machine is as important as knowing its specifications. Regular servicing helps the drill perform better, making it more efficient and prolonging its lifespan. Manufacturers recommend cleaning the drill first before carrying out any servicing. They advise using a clean, soft cloth to get rid of any debris or dust that may have accumulated on the machine.
Deep hole drill machines require occasional lubrication. Lubricate any exposed parts that easily wear out with time. These may include rails and gears, among other moving components. Regular lubrication reduces friction, keeping parts moving smoothly. Make sure to inspect the power cord and plug for any damages and signs of wear. If there is any damage, it’s best to replace them to avoid injury or accident.
Also, deep drilling machines need their blades to be sharpened regularly or replaced when they become dull. A sharp blade ensures clean and precise cuts. Finally, if the deep hole drill features a cooling system, ensure it’s always functioning properly. The cooling system prevents overheating during prolonged use.
Due to the various types of used deep hole drills and their character traits, they can be used in various industries and for several purposes.
When purchasing used deep hole drilling machines offered for sale, buyers should evaluate various aspects to guarantee they are buying the proper machine for their needs. One needs to check the overall condition of the equipment. This includes looking at parts like the frame, chuck, depth stop, feed mechanism, and others, as well as seeing if there are any visible signs of damage.
One would also want to ensure the drill functions properly. Mechanisms like the depth stop and feed mechanism should be functional, while the moving parts should have enough lubrication to operate smoothly. Bad feed mechanisms may lead to inaccurate drill holes. Therefore, buyers should also ensure that the machine drills precise holes by testing the drilling accuracy of the deep hole drill machine.
It is also advisable to examine the motor of the equipment to see if it requires huge repairs or servicing. Understanding the motor’s power rating will help buyers know the capacity and drilling speed they can expect from the machine. It is also wise to test the drill machine with different drill bits to gauge its performance and power.
Buyers who are unfamiliar with deep hole drilling machines should ask an expert to accompany them when purchasing the equipment. An expert can further educate and guide the buyer on what to look for when buying the particular drilling machine. Ultimately, buyers can be confident they are choosing an ideal equipment for their drilling needs.
Q1: How big is the deep hole drilling market?
A1: According to Fortune Business Insights, the global oil and gas drill market size was valued at USD 2.88 billion in 2021. It is projected to grow from USD 3.09 billion in 2022 to USD 4.62 billion in 2029.
Q2: What is the difference between a vertical and horizontal deep hole drill?
A2: In a vertical deep hole drill, the drill bit is aligned perpendicularly to the surface of the material being drilled. Vertically oriented deep hole drills are commonly used when precise control over the location and direction of the hole is required. Conversely, horizontal deep hole drilling machines have bits parallel to the horizontal plane. They are used to create holes that aren't accessible or feasible for vertical drilling.
Q3: What are some advantages of deep hole drill machining?
A3: Deep hole drilling has some perks. First, it's fast. This method makes long holes quickly and easily. Second, it's cheap. Deep hole drilling isn't too expensive compared to other methods. Third, it can handle big projects. Deep hole drilling works well for both small and big amounts. Finally, the drill creates precise holes, making it perfect for deep holes.
