Abstract: A crack self-healing functionally gradient material for ceramic cutting tools and a preparation method thereof. The material for ceramic cutting tools has a symmetrical gradient structure, and based on the percentage by mass, components of each layer include 50%-80% of Ti(C7,N3), 25%-5% of (W7,Ti3)C and 20%-0% of TiSi2; contents of components of layers that are symmetrical relative to a central layer are the same and a thickness is symmetrically distributed; a content of Ti(C7,N3) gradually increases from the surface layer to the central layer, contents of (W7,Ti3)C and Ti Si2 gradually decrease by 5% from the surface layer to the central layer, and the contents of Ni and Mo gradually increase from the surface layer to the central layer.

Abstract: A vascular structure-containing large-scale biological tissue and a construction method thereof. In the existing three-dimensional cell culture, it is contradictory for the elastic modulus of the scaffold material in ensuring structural stability and biocompatibility, and the vascular structure is required to provide channels for nutrient exchange when a large-scale structure is prepared. A cell-laden matrix material is poured into a hollow scaffold serving as a supporting scaffold. The overall stability of the scaffold structure can be ensured by regulating the mechanical properties of the supporting scaffold, thereby resolving the contradiction in ensuring structural stability and biocompatibility for the mechanical properties of the scaffold material in the conventional three-dimensional cell culture. A coaxially printing outer material contains a thermosensitive material. The removal of the outer thermosensitive material can increase the porosity of the vascular walls, and further increase the diffusion in the hollow vascular ducts.

Abstract: A milling machine fly-cutter with adjustable cutting-tool geometric angle and milling machine includes a fly-cutter plate body, a plurality of combination grooves are evenly set in the circumferential direction of the fly-cutter plate body, and adjusting assemblies are mounted in the combination grooves. Wherein, the adjusting assemblies include an adjusting block for rake angle and relief angle, an adjusting block for tool cutting edge angle and minor cutting edge angle, an adjusting block for tool cutting edge inclination angle. A first side of the adjusting block is attached with a cutter handle, and a second side is connected with the adjusting block for rake angle and relief angle by the adjusting block for tool cutting edge angle and minor cutting edge angle. The milling machine fly-cutter realizes adjustment of the geometric angles of cutting tool, and is able to adapt to cutter handles of a variety of different specifications.

Abstract: A BTA drilling quick-stop device (QSD) and a method, wherein the BTA drilling QSD includes a base. The base includes a hollow cavity. A side portion of the base has an opening communicating with the hollow cavity. The opening is closed by a through cover. A horizontally movable fixture is disposed in the hollow cavity. A stopper is disposed at a top portion of the base. A bottom portion of the stopper is disposed lower than a top portion of the fixture to stop the fixture from moving during processing. An elastic element is disposed between the through cover and a side portion of the fixture to push the fixture to move after processing.
