[0025] See also Figures 1 to 5 The utility model discloses an ultra-thin fine slice, which includes a substrate 1 and a fine slice cutter head 2 sintered and fixed on the outer circumference of the substrate 1 and in a circular ring shape, wherein the upper and lower side surfaces of the fine slice cutter head 2 are respectively provided with a plurality of turbine-distributed fine teeth 21, and the fine teeth 21 on the upper and lower side surfaces of the fine slice cutter head 2 are staggered and connected to form an integral structure; the interval between two adjacent fine teeth 21 on the same side surface forms a groove 22, and two reinforcing ribs 23 connecting two adjacent fine teeth 21 are provided in the groove 22; the reinforcing ribs 23 located in two adjacent grooves 22 on the fine slice cutter head 2 are staggered.

[0026] The ultra-thin fine slice of the utility model is provided with two reinforcing ribs 23 between two adjacent fine teeth 21, and the reinforcing ribs 23 located in two adjacent grooves 22 on the fine slice cutter head 2 are staggered. The reinforcing ribs 23 at different positions cause the fine teeth 21 distributed in the turbine to be squeezed and pulled against each other, thereby enhancing the strength between the fine teeth 21 and the fine teeth 21, thereby enhancing the structural strength of the ultra-thin fine slice and extending its service life; moreover, the cold pressing formability can be improved, the phenomenon of sintering cracks can be avoided, and the risk of cracks occurring in the fine slice cutter head 2 during the cutting process can be reduced.

[0027] The reinforcing ribs 23 in two adjacent grooves 22 on the same side of the utility model are staggered; the same fine tooth 21 is connected with two grooves 22 on the same side and one groove 22 on a different side, compared with the same fine tooth 21 being connected with six reinforcing ribs 23 in different directions, so that the structural strength of the fine slicing cutter head 2 is stronger and the service life is longer.

[0028] The utility model comprises six reinforcing ribs 23 in three connected grooves 22 on the same side as a group, and the six reinforcing ribs 23 in the same group are arranged in an interval and staggered manner from the inside to the outside, and the multiple groups of reinforcing ribs 23 on the same side are distributed in a turbine shape; that is, the three reinforcing ribs 23 close to the center of the base 1 in the three grooves 22 are connected to form an arc line extending from the inside to the outside, and the three reinforcing ribs 23 far from the center of the base 1 in the three grooves 22 are connected to form an arc line extending from the inside to the outside, and the multiple groups of reinforcing ribs 23 on the same side are distributed in two groups of turbine lines; by regularly adding reinforcing ribs 23 in the middle on the basis of conventional turbine fine teeth 21, mutual extrusion and entanglement are formed between the fine teeth 21 and the fine teeth 21, thereby enhancing the strength between the fine teeth 21 and the fine teeth 21, thereby improving the cold pressing formability and extending the service life of the precision slice.

[0029] The fine teeth 21 and the reinforcing ribs 23 on the same side of the utility model are respectively distributed in a clockwise turbine direction; or, the fine teeth 21 and the reinforcing ribs 23 on the same side are respectively distributed in a counterclockwise turbine direction.

[0030] The precision slicing cutter head 2 of the present invention forms an annular groove 24 wrapped around the outer circumference of the substrate 1 on the inner ring close to the outer circumference of the substrate 1, and reinforcement parts 25 formed on both sides of the annular groove 24 are respectively provided in the grooves 22 on the upper and lower sides; the precision slicing cutter head 2 can be firmly sintered on the substrate 1.

[0031] The fine teeth 21 and the reinforcing ribs 23 of the utility model are integrally formed, and the structural strength of the fine slicing cutter head is stronger and the cutting efficiency is better.

[0032] The fine teeth 21 of the utility model are gradually expanded from one end close to the base body 1 to the end far away from the base body 1; the cutting performance is better.

[0033] The two side surfaces of the base 1 of the utility model are respectively welded with flanges 11, and the base 1 is provided with four elongated holes 12 penetrating the upper and lower side surfaces on its circumference, and the length direction of the elongated holes 12 is in the diameter direction of the base 1; the outer circumference of the flange 11 has a welding portion 111 welded to the side surface of the base 1 and four vacant portions 112 spanning the elongated holes 12 and not welded to the base 1.

[0034] The utility model provides a base 1 with four elongated holes 12 penetrating the upper and lower side surfaces on its circumference, and the outer circumference of the flange 11 has a welding portion 111 welded to the side surface of the base 1 and four vacant portions 112 spanning the elongated holes 12 and not welded to the base 1; during the welding process of the flange 11, the vacant portions 112 of the flange 11 spanning the elongated holes 12 are not welded to the base 1, and the elongated holes 12 and the vacant portions 112 can provide deformation clearance space, which can release internal stress, thereby solving the problem that the flange 11 is easily deformed when welded to the base 1, increasing the structural strength of the base 1, extending the service life of the precision cut piece, and improving the feel of the precision cut piece.

[0035] The substrate 1 of the utility model is provided with a plurality of circular holes 13 on the circumference near the fine slicing cutter head 2. The problem of deformation of the substrate 1 after sintering due to the inability to release internal stress is solved by these elongated holes 12 and circular holes 13 of different shapes.

[0036] The number of the circular holes 13 in the present invention is eight, and a circular hole 13 is symmetrically arranged on both sides of each long strip hole 12, so that the internal stress is released more evenly and the base body 1 is not easily deformed.

[0037] The diameter of the circle where the outer end of the elongated hole 12 of the utility model is located is larger than the diameter of the circle where the inner end of the circular hole 13 is located. The outer end of the elongated hole 12 is the farthest point of the elongated hole 12 from the center of the substrate 1, and the inner end of the circular hole 13 is the closest point of the circular hole 13 to the center of the substrate 1. The spaces for releasing internal stress of the elongated hole 12 and the circular hole 13 overlap, and the internal stress is released more evenly, and the substrate 1 is not easily deformed.
