Problems solved by technology
Taking sanitary fittings as an example, the thin-walled drills in the prior art can only be used for drilling holes. If the edge of the hole needs to be further trimmed and polished to a certain taper to facilitate the installation of sanitary fittings, additional hole reamers are required for further trimming. cumbersome
In addition, the drilling speed of diamond drills is also severely restricted by the diamond cutter head. For the drilling process of granite or marble and other stones, diamonds are likely to be polished or flattened under high-speed drilling conditions, and even large-scale damage occurs. Premature detachment phenomenon, resulting in significantly reduced service life

Embodiment 1
[0023] Such as Figure 1-2 As shown, the dual-purpose multifunctional diamond drilling drill of the present embodiment includes a thin-walled drill pipe seat 10, and the thin-walled drill pipe seat 10 includes a thin-walled drill base 11, and is located at the thin-walled drill base 11. The thin-walled drill pipe body 13 on. The thin-walled drill base 11 is provided with a mounting portion 12 that cooperates with a rotating shaft (rotary drive component, such as a motor-driven rotary drive component), and the mounting portion 12 extends from the bottom of the thin-walled drill base 11 to the In the bottom of the thin-walled drill pipe body 13. In the present invention, the thin-walled drill pipe seat is processed from No. 20 steel, and the element composition of the No. 20 steel is: 0.17-0.24wt% carbon, 0.17-0.37wt% silicon, 0.35-0.65wt% Manganese, sulfur ≤ 0.035, phosphorus ≤ 0.035, chromium ≤ 0.25, nickel ≤ 0.25, copper ≤ 0.25, the balance is iron and other unavoidable imp...

The invention relates to a dual-use multi-functional diamond perforating drill for polishing and drilling. The dual-use multi-functional diamond perforating drill for polishing and drilling belongs to the technical field of diamond tools, and comprises a thin-wall drilling pipe seat. The thin-wall drilling pipe seat comprises a thin-wall drilling base and a thin-wall drilling pipe body; an integrated diamond tool bit is brazed on the thin-wall drilling pipe body; a plurality of diamond polishing blocks are alternately arranged at the upper surface of the thin-wall drilling base; and an included angle a between each diamond polishing block and the thin-wall drilling pipe body is an obtuse angle. The diamond perforating drill provided by the invention can accomplish a perforating process and a polishing process of stone materials at a time, so that the processing efficiency is remarkably improved; and the adopted diamond tool bit is fast in protruding speed and better in holding diamonds, so that diamond particles can maintain higher protruding height, the phenomenon of earlier falling off cannot occur, and the operating requirements on high-speed drilling granite, marble and other stone materials can be met.
Description
technical field [0001] The present invention relates to the technical field of diamond tools, more specifically, the present invention relates to a kind of dual-purpose diamond drill for grinding and drilling. Background technique [0002] In the construction industry, diamond drills have been widely used in the drilling and processing of granite, marble, concrete, ceramics and other materials. For example, opening the water hole of the bathroom washbasin, drilling holes on the surface of granite, etc. Most of the traditional diamond drills use divided teeth, the welding area of a single cutter head is small, the welding strength is low, and it is easy to lose teeth during the drilling process, which will cause the thin-walled drill to fail to work or even be scrapped. In the prior art, it is necessary to additionally select a grinding head for repeated grinding for drilling. Taking sanitary fittings as an example, the thin-walled drills in the prior art can only be used...
