the bottom surface of the lamination is connected with the base, the lamination and the base are integrally formed, the cross section of the lamination is in a T shape, the lamination is arranged along a tapered thread line, the diameter of a reference circle of the bottom surface of the tapered thread line is 3 mm, the height of the bottom surface of the tapered thread line is 100 mm, the number of turns of the bottom surface of the tapered thread line is 50 turns, the thread pitch is 2 mm, the direction of the bottom surface of the tapered thread line is clockwise, and the taper is contracted by 0.75 degrees;
the lamination is provided with two grooves, the two grooves are arranged in an axisymmetric manner by taking the axis of the lamination as a reference axis, the grooves are parallel to the axis of the lamination, the cross section of each groove is triangular, and the angle of the cross section of each groove close to the axis of the lamination is 30 degrees;
further, the production method comprises the following steps:
s1, preparing a mold of the base and a laminated mold;
s2, preparing a low mold of the base and the laminated mold by using the mold obtained in the step S1 through a casting method;
s3, welding the low die of the base obtained in the step S2 and the laminated low die together by using a friction welding method;
and S4, polishing and deburring the low die of the base and the laminated low die obtained in the step S3 by using a CNC machining center.
By adopting the technical scheme, the drill bit has higher strength and toughness, and can efficiently drill holes in the root canal.

Detailed Description
In order to better explain the invention, the invention will be further described with reference to the following examples, which should be construed as merely illustrative and not limitative of the remainder of the disclosure;
example one
As shown in fig. 1 to 5, a high-strength laminated root canal file and a production method thereof, wherein the base 1 is made of 304 stainless steel, and is characterized by further comprising a laminate 2, and the laminate 2 is made of nickel-titanium alloy;
the bottom surface of the lamination layer 2 is connected with the base 1, the lamination layer 2 and the base 1 are integrally formed, the cross section of the lamination layer 2 is T-shaped, the lamination layer 2 is arranged along a tapered thread line, the diameter of a reference circle of the bottom surface of the tapered thread line is 3 mm, the height of the bottom surface of the tapered thread line is 100 mm, the number of turns of the bottom surface of the tapered thread line is 50 turns, the thread pitch of the bottom surface of the tapered thread line is 2 mm, the direction of the bottom surface of the tapered thread line is clockwise, and the taper is contracted by 0.75 degrees;
the lamination layer 2 is provided with two grooves 3, the two grooves 3 are arranged in an axisymmetric manner by taking the axis of the lamination layer 2 as a reference axis, the grooves 3 are parallel to the axis of the lamination layer 2, the cross sections of the grooves 3 are triangular, and the angle of the cross section of each groove 3 close to the axis of the lamination layer is 30 degrees;
the groove 3 mainly has the function of ensuring the toughness of the invention and avoiding the phenomenon that the invention cannot be bent due to too high hardness;
the production method comprises the following steps:
s1, preparing a mold of the base 1 and a mold of the lamination layer 2;
s2, preparing a low mold of the base 1 and a mold of the lamination layer 2 by using the mold obtained in the step S1 through a casting method;
s3, welding the low die of the base 1 obtained in the step S2 and the low die of the lamination layer 2 together by using a friction welding method;
and S4, polishing and deburring the low die of the base 1 and the low die of the lamination layer 2 obtained in the step S3 by using a CNC machining center.
In using the present invention, a medical practitioner attaches the present invention to a dental drill or the like via base 1 and then aligns the thinner end of laminate 2 with the dental lesion of the patient.
The above embodiments are only illustrative of the present invention, and the present invention is not limited to the embodiments described above.
