Introduction to the difference between different drilling

Center drilling will help you to countersink center holes. This will mount the work piece between center for gridding or turning.Deep hole drilling is when you drill a deep hole in your workpiece. Usually, the depth is ten times the size of the diameter of the hole. You will be needing special equipment to drill such hole. There are other types of drilling as well. Such as Micro drilling, Vibration drilling etc.

Deep hole drilling also differs from normal drilling in that, depending on the drilling process and the drilling diameter, cooling lubricant must be pumped to the cutting edges in large quantities and under high pressure. This ensures good cooling and at the same time good lubrication of the contact areas between the workpiece and the cutting edge of the tool on the one hand and the workpiece and guide pads of the tool on the other.

HTT can provide deep hole drilling solution: Job-shop + Machines + Tools.

A deep hole is defined as one that is a minimum of 10 times its diameter in depth. On the maximum side, a deep hole drilling is generally capable of drilling to a depth of 100 to 150 times its diameter. And hole deeper than 10 times the diameter should certainly be considered a deep hole, requiring a specialised drilling technique. Deep hole drilling are characterized by high material removal rate plus high accuracy with regard to the straightness of the hole, surface finish and dimensional tolerances. The extreme conditions which apply when drilling deep holes place high demands on the tool, machine and associated equipment.

1.The main difference between drilling, boring and reaming is that drilling is when you make a brand new hole in your work piece. But boring is when you enlarge the hole. When you give a finishing touch to your hole that means you are reaming. Giving a finishing touch to the hole means making the hole smoother. 2.Next thing about the three processes is that they have individual tools for them. The process of drilling uses a drill bit. But the boring process uses a lathe and reaming uses reamers. So there is also a difference in terms of tools. 3.The process of boring always comes after the drilling. And reaming comes at last. The sequence is always the same. You cannot bore until you drill. And you cannot ream until you bore. So by drilling, you can directly have a hole you want. But boring and reaming are the helping processes. Or they are the processes that will make a better hole.
