What is honing machine?

What is honing machine?

A grinding and lapping machine tool used for honing. Honing machines include vertical, horizontal, and inclined configurations, single-spindle and multispindle types, machines for external and internal honing, and universal, semiautomatic, and automatic machines. The cutting tool, or hone, is attached to a spindle and is equipped with fine-grain abrasive rods, or sticks. The principal motion of the tool (rotation) is produced by a separate electric motor or hydraulic turbine, and the feed motion (rectilinear or reciprocating) is usually obtained from an hydraulic drive. There is also a radial feed mechanism that provides for the rapid feed of the sticks toward the surface being processed and ensures automatic compensation for wear during operation. The most common honing machines are semiautomatic types for honing blind and through holes.

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.
