Processing Technology of Spindle Parts

Processing Technology of Spindle Parts:

First: the principle of process formulation

1, First rough and then fine.

2, first near and then far: the parts close to the cutting point are processed first, and the parts far away from the cutting point are processed later.

3, first inside and then outside: first arrange the rough machining of internal and external surface, and then finish the internal and external surface.

4, the minimum program segment: make the program simple, reduce the probability of error and improve the efficiency of programming.

5, the shortest route: on the premise of ensuring the quality of processing, so that the processing program has the shortest route, not only can save time, but also can reduce the consumption of cutting tools and machine tool feeding mechanism sliding parts wear.

Two: the division of the working procedure

1, to an installation, processing as a process: suitable for processing less parts.

2, with the same tool processing content division process.

3, to process parts of the division of the process: suitable for a lot of processing content of the workpiece.

Three: clamping method

The general fixture of several cars is the chuck, which is divided into three jaw and four jaw chuck.The use of three jaw chuck processing shaft parts, parts to the axis and the center line of the chuck coincidence, generally do not need to correct, fast clamping speed.Four jaw chuck can clamp non-cylindrical parts, or clamping parts and processing parts are not coaxial parts.For parts with higher precision requirements, the following machining methods are commonly used:

1, two top clamping: used for long or must go through several clamping to complete processing.Such as long shaft, screw, etc.Convenient clamping, no need to correct, high clamping accuracy.But before clamping must first drill the center hole in the workpiece end face.

2, a top and a clip installation: with two top clamping workpiece although high accuracy, but the rigidity is poor, affecting the increase of cutting amount.Turning general shaft parts, especially the heavier workpiece, can not use two top clamping, and with one end of the clamp, the other end with the top of the clamping method.
