Micro-rod is the necessary tool of micro-structure machining,and the micro-rod machining with high precision is the foundation for the development of product miniaturization.

Based on the questions of micro-rod machining, non-traditional machining(NTM) which are used widely are analyzed.

Experimental Study on the Effects of the Cutting Depth on Machining Precision of the Micro-shaft;

The technology may be employed in micro-shafts processing by the special movement mode.

From nine aspects,such as cutting mode,cutting velocity,cutting force and so on,traditional turning and advanced turn-milling technology were compared in micro-shaft machining trails,respectively.

Automatic calculation contributing to the matched size of miniature bearing;

Autonomous manufacturing island model and miniature bearing production;

In view of actualities that the internal bore of precision miniature bearing below 2mm is difficult to grind conventionally,the spark grinding of the internal bore is realized initially by adopting two-rod backup structure,increasing the amplitude and the velocity of reciprocating oscillation during process and changing the quasi parameters of electric gauge reasonably.

By using this apparatus,such micro shaft which diameter is about 4.

Therefore, micro shaft, micro hole, and 3D microstructure can be ma.

In terms of the disadvantages of the two presently comparatively advanced interval automatic blocking technologies: ZPW-2000A jointless shifting frequency automatic blocking and microcomputer axle counter technology,this paper combines them based on actual projects to complement each other so as to improve the efficiency and safety of rail transport.
