Application of single crystal diamond tool

The hardness of diamond tool is hv9000-10000, which is the hardest material known in nature. The tool can keep the size stable for a long time in cutting, so it has a long service life. The cutting tool made of natural diamond has no gap under 400 times microscope. It is suitable for processing gold, silver, copper, aluminum (aluminum alloy), zinc (zinc alloy), acrylic (plexiglass) and other materials. The surface roughness can reach RA (0.01-0.025) μ M.

Application of diamond cutter

Natural single crystal diamond tool is suitable for finishing copper, aluminum and its alloy materials. It is widely used in the fields of jewelry, watches, instrument manufacturing, LED products, acrylic products, aluminum products, aerospace, automobile and other fields, such as: Motorcycle wheel hub, turning camera, mobile phone parts high light parts, precious metals, various hardware high gloss shell, watch hub, surface calendar window, pen making, fishing gear Contact lenses, etc. It has the characteristics of low loss, long life, easy to use, and can ensure high machining accuracy and mirror surface finish.

According to the parts, processing methods, shapes and uses of diamond tools, there are also different naming methods. The following shows the names and uses of some common diamond tools.

Diamond MCD arc knife

Widely used in non-ferrous metal 6C industry parts (aluminum mobile phone case highlight, aluminum smart watch highlight, communication accessories, automotive aluminum copper accessories, aluminum products highlight, gold and silver jewelry, optical components)

Ultra fine diamond slotting cutter

Hologram around grating, linear micro groove processing, can process edge width 5um, the world's smallest groove, can be one-time molding, can not be grinding.

Diamond high gloss knife

According to different welding methods, chamfering cutters can be divided into two types: high gloss chamfering cutter and high gloss milling cutter. High gloss chamfering knife can be used for digital camera shell, DVD / VCD / audio knob, furniture decoration and digital lens. The high gloss chamfering knife with single side welding method is used for the shell chamfering of iPhone / iPad, which can achieve the effect of no burr, no scratch, good drainage and specular highlight.

Single crystal diamond spiral milling cutter

The diamond spiral milling cutter is generally used for the processing of Apple phone keys and earpieces. The small diameter single edge diamond spiral milling cutter is suitable for micro hole machining, and can carry out continuous vibration free good cutting process, so as to obtain better surface roughness.

Diamond blade

Compared with sintered diamond, it has better sharpness and better heat dissipation of cutting heat. It can make the dry and semi dry cutting of die-casting aluminum alloy more simple, thus achieving the purpose of greatly reducing the price.

Diamond polishing knife

It can be used for the fine polishing of acrylic plate, LCD panel, light guide plate module, mirror, central air conditioning frame and aluminum alloy plate. It can also be used for vertical machine tools. The requirements for the handle of diamond polishing knife are BT40 / 30, the recommended speed is 3000 (min-1), the feed rate is 120-200mmr / min, and the feed rate is 0.03-0.05mm. According to the cutting depth, the rigidity of the machine tool and other use conditions, to reasonable adjust the number of revolutions and feed.

Diamond turning tool

The diamond turning tools produced by our company include sharp turning tool for turning motor rotor, CD turning tool with aluminum alloy shell, flat bottom turning tool, cylindrical turning tool and high gloss chamfering turning tool, which are widely used for cutting copper, aluminum alloy, stainless steel and other materials.

Diamond Flower cutter

It can be used for engraving the nameplates of various aluminum alloy shells, such as gold jewelry car flower, mobile phone shell, repeater shell, etc., to achieve high gloss effect.

Diamond shaped knife

It can be used for mobile phone handset, notebook, audio, acrylic and PC panel surface processing, can achieve high gloss mirror effect.

In order to improve the service life of the tool and avoid unnecessary problems, please pay attention to the following points when using:

1. Do not touch the diamond tip directly with fingers or other objects, only the workpiece;

2. Because of the hardness and brittleness of diamond tools, the feed rate should be from small to large, and the feed speed should be from slow to fast. The cutting parameter should not exceed 0.05mm. Higher cutting speed can reduce the cutting force, while low speed cutting will increase the cutting force, which will accelerate the tool edge failure. Therefore, the cutting speed should not be too low when using diamond cutting tool.

3. In the process of testing and turning, please note that the tool can not turn ferrous metals (ferrous metals), and can contact non-ferrous metals (gold, silver, copper, aluminum, etc.) and plastics. When black metal is encountered during turning, it is very likely that the tool will collapse, fracture or even be scrapped directly.

4. In the process of use, if there is wear, it can be detected by microscope. If it is within the scope of repairable grinding, it can be repeatedly used to save cost. If it is beyond the measurable wear range, the tool needs to be replaced.
