Abstract
The utility model discloses a corn milling cutter with high finish requirement, which comprises a cylindrical cutter base body and a cylindrical cutter head positioned at the front end of the cutter base body; the axial outer surface of the cylindrical cutter head is provided with long-edge cutter teeth, and the length of the long-edge cutter teeth is the same as that of the cutter head; one or more splicing teeth are arranged at other positions of the cutter head, and semi-cylindrical grooves are formed in the splicing teeth; the splicing teeth are arrayed and rotate and stagger along the anticlockwise direction, and each splicing tooth has an inclination angle with the axis of the cutter base body. Compared with the whole long-blade structure cutter, the utility model has smaller cutting force, smaller processing vibration and better surface smoothness of the processed workpiece; compared with the common corn structure cutter, the utility model adds a finish machining cutting edge, so the surface smoothness of the processed workpiece is better; and the processing efficiency is greatly improved while the surface smoothness is improved.
Description
Technical Field
The utility model belongs to the machining field, concretely relates to maize milling cutter that high finish requires.
Background
A milling cutter is a rotating tool for milling machining having one or more cutter teeth. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The cutting edges of the end mill are mainly on the circumference and are fed in the direction perpendicular to the axial line to cut during operation. For the end milling cutter with longer cutting edges, the end milling cutter can be generally designed into a corn structure, the length of the total cutting edge is guaranteed through multi-edge splicing, the cutting force is reduced because of different cutting, but the condition that the splicing edges are connected with each other to form a tool connecting mark often occurs, and the finish degree of a machined surface is poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims at improving the cutting edge structure of the existing milling cutter, and can also ensure the processing finish degree when reducing the cutting force.
The utility model adopts the technical proposal that: a corn milling cutter with high finish requirement comprises a cylindrical cutter base body and a cylindrical cutter head positioned at the front end of the cutter base body; the axial outer surface of the cylindrical cutter head is provided with long-edge cutter teeth, and the length of the long-edge cutter teeth is the same as that of the cutter head; one or more splicing teeth are arranged at other positions of the cutter head, and semi-cylindrical grooves are formed in the splicing teeth; the splicing teeth are arrayed and rotate and stagger along the anticlockwise direction, and each splicing tooth has an inclination angle with the axis of the cutter base body.
Further, the radial height of the splicing teeth is 0.02 mm-0.05 mm lower than that of the long-edge cutter teeth.
The utility model discloses the beneficial effect who produces is: compared with the whole long-blade structure cutter, the utility model has smaller cutting force, smaller processing vibration and better surface smoothness of the processed workpiece; compared with the common corn structure cutter, the utility model adds a finish machining cutting edge, so the surface smoothness of the processed workpiece is better; and the processing efficiency is greatly improved while the surface smoothness is improved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the utility model relates to a maize milling cutter with high finish requirement, which comprises a cylindrical cutter base body 7 and a cylindrical cutter head arranged at the front end of the cutter base body. The axial outer surface of the cylindrical cutter head is provided with long-edge cutter teeth 1, and the length of the long-edge cutter teeth 1 is the same as that of the cutter head; one or more splicing teeth are arranged at other positions of the cutter head, and semi-cylindrical grooves are formed in the splicing teeth; the splicing teeth are arrayed and rotate and stagger along the anticlockwise direction, and each splicing tooth has an inclination angle with the axis of the cutter base body.
Specifically, as shown in fig. 2 to 5, the first joint tooth 2, the third joint tooth 4, and the fifth joint tooth 6 are located on the same straight line, and the second joint tooth 3 and the fourth joint tooth 5 are located on the oblique sides of the first joint tooth 2 and the third joint tooth 4. The utility model discloses reach the effect that reduces the cutting force with crisscross concatenation tooth.
The utility model discloses in, the radial height of concatenation tooth is less than long sword tooth 0.02mm ~0.05mm, therefore the final surface finish of work piece leans on whole long sword blade to guarantee, can not appear connecing the tool mark.
Claims (2)
1. A maize milling cutter that high finish required, its characterized in that: comprises a cylindrical cutter base body and a cylindrical cutter head positioned at the front end of the cutter base body; the axial outer surface of the cylindrical cutter head is provided with long-edge cutter teeth, and the length of the long-edge cutter teeth is the same as that of the cutter head; one or more splicing teeth are arranged at other positions of the cutter head, and semi-cylindrical grooves are formed in the splicing teeth; the splicing teeth are arrayed and rotate and stagger along the anticlockwise direction, and each splicing tooth has an inclination angle with the axis of the cutter base body.
2. The corn milling cutter with high finish requirement as claimed in claim 1, wherein: the radial height of the splicing teeth is 0.02 mm-0.05 mm lower than that of the long-edge cutter teeth.
