The classification and processing characteristics of reamer and its application

1. What is a reamer? How do you describe what it looks like?

Tungsten steel reamer A rotary tool with one or more teeth for cutting holes of thin metal layers on the machined surface.

2, the hole after reamer processing can be obtained accurate size and shape.

The reamer is used to drill (or reaming) the hole after machining on the reamer workpiece, mainly to improve the machining accuracy of the hole and reduce the roughness of the surface. It is a tool for the finishing and semi-finishing of the hole, and the processing allowance is generally small.

3, What are the categories of reamer?

Reamers for machining cylindrical holes are commonly used.

The reamer for processing taper holes is a taper reamer, which is less used.

According to the use of hand reamer and machine reamer, machine reamer can be divided into straight shank reamer and taper shank reamer, the hand is straight shank type

4, What are the types of reamer according to the material?

According to the material of the tool body, the reamer can be divided into tungsten steel reamer, high-speed steel reamer, high-speed steel reamer containing cobalt, welding alloy reamer, PCD reamer, etc., this paper mainly introduces tungsten steel reamer, tungsten steel reamer is also called alloy reamer

5. How can the reamer be distinguished by design?

Tungsten steel reamer design can be divided into: straight groove reamer, left hand reamer, right hand reamer, large spiral reamer;

6. What are the cooling methods of the reamer?

The cooling method of tungsten steel reamer can be divided into: ordinary, direct injection internal cooling, umbrella cooling method, the best life and effect is the last one.
