Extended Reversing Point

The extended live center is an essential component of machine tool accessories, primarily used for machining shaft-type parts on lathes. By utilizing the center hole for positioning, it ensures high dimensional accuracy for the workpiece. Below is a detailed introduction to the extended live center:

I. Definition and Structure

1. DefinitionAn extended reversible center drill is a type of drill point with a conical head and shank that can rotate relative to each other, featuring a longer length compared to standard reversible center drills to meet specific processing requirements.

2. StructureTypically composed of parts such as the centering pin, clamping device, housing, fixing pin, bearing, and mandrel. One end of the centering pin can abut the center hole or the inner bore of the tube material, while the other end can fit into a part with a spherical or conical top surface.

II. Features

1. High precisionThe extended type rotating center bit offers high-precision machining, ensuring the dimensional accuracy and surface quality of the workpiece.

2. High-speedDue to its small outer diameter and fewer interference cuts, it is suitable for high-speed machining and can meet the demands of high-speed cutting.

3. Good stabilityUtilizing long needle roller bearings with a three-point support arrangement, enhanced rigidity, and excellent stability, ensuring stability during the machining process.

4. Waterproof featureIt features a certain degree of waterproofing, excellent heat dissipation, and can maintain normal operation in harsh processing environments.
