An insert coaxial thermal radiation image evaluating system includes a cage support, first lens, first cage movable frame, second cage movable frame, cage holder and light detector. The first cage movable frame is movably disposed at the cage support and connected to the first lens. The second cage movable frame is movably disposed at the cage support and connected to the light detector. The cage holder is connected to the cage support to fix the cage support to an optical substrate. The first cage movable frame is movably disposed in the cage holder. The first lens and a second lens of a metal additive manufacturing system together form a structure of conjugate foci, such that a thermal radiation generated from a high-power infrared laser irradiation zone forms according to a fixed ratio an image captured by the light detector.

Insert coaxial thermal radiation image evaluating system

The present invention discloses a grinding cavity body of multiple vibration sources, in which a plurality of ultrasonic vibration sources are disposed, capable of controlling the multi-directional macroscopic medium flow, making benefits to the vibration medium (the abrasive of the slurry) to enter the fine structure of the workpiece to be processed, and to the abrasive to vibrate itself slightly to enhance the performance of abrasive to the workpiece which needs to be ground.

Grinding cavity body of multiple vibration sources

The present invention discloses a multi-dimensional vibration grinding cavity body. By adjusting amplitudes (power) and frequencies of the multi-dimensional ultrasonic vibration source, such that the multi-directional macroscopic flow is formed in the cavity body while keeping the vibration medium to have the original characteristics to improve the performance of grinding of slurry.
