Abstract
The present invention relates to a process for manufacturing a dental burr from a cylindrical part of a niquealuminium alloy by moving the cylindrical part at a feed rate VA beyond a rotary abrasive wheel whose variable diameter disc has a linear speed VL which is related to the speed at which the material is removed, characterized in that the linear velocity VL is greater than about 91440 cm / min and the feed rate VA is less than about 7.62 cm / m
Description
DENTAL OBTAINED FROM THE SAME
DESCRIPTION OF THE INVENTION
The subject of the present invention is a process for the manufacture of nickel-titanium alloy reamers (known under the name of NITI). The dental reamers are manufactured mainly from a cylindrical metal sketch, usually composed of at least 40% titanium, although this proportion is not critical for the performance of the procedure. The metallic rod-shank is moved at a feed speed VA to a rotating wheel whose disk, of variable diameter, determines a linear speed VL of evacuation of material from the rod by the rotating wheel. Another important parameter is the one determined by the size of the grain of the wheel, which in this case, in general, is a diamond wheel. We have described in US Pat. No. 5,464,362 a method of this type in which the claimed and described values are the following: VA between 7.62 and 20.32 cm / mn, DG greater than 200 grains. Surprisingly, and in total contradiction with what is considered as the optimal conditions in the previous system procedure, it has been shown that opposite operating conditions gave some
results at least equal. The present invention consists consequently in a process for the manufacture of titanium nickel alloy reamers, manufactured from a REF: 26172 cylindrical metal sketch displaced at a feed speed VA before a rotating wheel whose disc of variable diameter determines A linear velocity V- of material evacuation, with the following parameters: - VL higher than 91440 cm / mn, - VA lower than 7, 62 cm / mn Advantageously, the grains of the grinding wheel will have a grain greater than 46. According to a preferred embodiment, the wheel will be a diamond wheel.To obtain an optimal result, the parameters used will be the following: 'J - VL = 2213 m / mn, - VA = 3.2 cm / n Naturally , it is understood that all the elements of the procedure are identical to those of the previous system procedure.It is stated that in relation to this date, the best method known by the request It is clear from the present description of the invention to carry out the aforementioned invention. Having described the invention as above, property is claimed as contained in the following:
