Abstract
The utility model belongs to the technical field of grinders and abrasives and relates to a grinding needle. The grinding needle is characterized in that the grinding needle comprises a clamp and a needle rod; the clamp is provided with a structure clamped on a grinding machine; the needle rod is a cylinder of which the diameter is less than 2mm; the material of the needle rod is diamond; and for saving the diamond material, the outside of the needle rod is made from the diamond material, while the inside thereof is made from a bearing steel. For fulfilling the aim of drilling, the end part of the needle rod is also provided with a drill bit. The grinding needle has effect of grinding pores and also can be used for drilling.
Description
Technical field
Technical field under the utility model relates to the grinding tool abrasive material, relates to a kind of card grinding.
Background technology
For the object that has than aperture, prior art is not ground; Along with the raising of machining accuracy, also want precision to grind to the aperture of some objects, also be not specifically designed to the milling tool of this respect at present.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned defective, and a kind of card grinding that can grind aperture is provided.
Technical solution adopted in the utility model is such, and card grinding is characterized in that: comprise anchor clamps and shank, anchor clamps have the structure of clip on grinder, and shank is a diameter less than 2 millimeters cylinder.
The material of shank is a diamond.
In order to save diamond, the outside of described shank is a diamond, and inside is bearing steel.
Grind the littler object in aperture in order to reach, described shank is a diameter less than 1 millimeter cylinder.
In order to reach the purpose that can hole simultaneously, the end of described shank also has drill bit.
The beneficial effects of the utility model are: have the effect that can grind aperture, can also hole.
Description of drawings
Fig. 1 is the tangent plane structural representation of the utility model card grinding
Wherein, 1, anchor clamps 2, shank 3, inside 4, drill bit
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in the figure, card grinding is characterized in that: comprise anchor clamps 1 and shank 2, anchor clamps 1 have the part of clip on grinder, and shank 2 is diameters less than 2 millimeters cylinder.
The material of shank is a diamond.
In order to save diamond, the outside of described shank 2 is diamonds, and inner 3 is bearing steels.
Grind the littler object in aperture in order to reach, described shank 2 is diameters less than 1 millimeter cylinder.
In order to reach the purpose that can hole simultaneously, the end of described shank also has drill bit 4.
Such card grinding, anchor clamps 1 have the structure identical with the bistrique of prior art, so grinding machine is general, because diameter is less, can grind the small-bore object, satisfy the requirement that aperture is ground.
Claims (5)
