The invention discloses an electromotor and permanent
magnet series
connection type vascular stent tube material inner wall magnetic particle
grinding and
polishing machine. The electromotor and permanent
magnet series
connection type vascular stent tube material inner wall magnetic particle
grinding and
polishing machine comprises a rotating magnetic pole movement transmission device, a rotatingmagnetic pole device, a
vascular stent tube material clamping and feeding device, a
machine base and a
numerical control system. A pair of permanent
magnet magnetic poles which are opposite in positive pole and negative pole are arranged in a magnetic pole roller of the rotating magnetic pole device, micro grooves are formed in the surfaces of the
magnetic poles, and the size of a magnetic gap isadjusted by a
threaded rod. Guide bases which are same in shape and size are installed at the two ends of the rotating magnetic pole device. The electromotor and permanent magnet series
connection type vascular
stent tube material inner wall magnetic particle
grinding and
polishing machine can conduct inner wall
surface layer removal and polishing operation on vascular
stent tube materials with different materials, different lengths and different hole diameters, quickly removes defect
layers which exist on the inner wall surfaces, and remarkably reduces the frequency of the phenomenon that after
vascular stents are implanted into blood vessels, the toxic and side effects,
blood flow object deposition, thrombi, vascular
restenosis, blockage and other phenomena happen on patients. Meanwhile,the electromotor and permanent magnet series connection type vascular
stent tube material inner wall magnetic particle grinding and polishing machine is suitable for uniform trace removal and mirrorpolishing
machining of the inner wall surfaces of various ultra-thin and ultra-long tube materials.
