Natural diamond high-gloss cutting tools for milling copper parts, aluminum plates, etc. Ultra-fine turning technology to obtain optical mirror surface is a new technology developed in the 1960s. It is nearly 60 years old. In addition to the computer numerical control (CNC) ultra-precision lathes that have appeared in recent years, CNC high-gloss processing has made great breakthroughs, making it possible for high-gloss milling to replace grinding.

1. The elements of CNC high-gloss processing

In recent years, with the development of high-performance, high-precision CNC machine tools and excellent diamond tools. The CNC high-gloss processing technology has made a major breakthrough, and the high-gloss milling and grinding technology is mature. The principle of CNC high-gloss machining is to use diamond high-gloss tools on precision CNC processing equipment to achieve a shiny surface effect with scientific and reasonable cutting parameters and processes.

The elements of CNC highlight processing are summarized as follows:

Machine tool: Since high-gloss processing requires the machine tool to have good rigidity and precision, the use of precision CNC machine tools is a prerequisite for high-gloss processing. Such as precision CNC engraving machine (general speed is 20000~100000 rpm);

Knives: To achieve high-gloss effect, diamond high-gloss knives are needed. Diamond high-gloss knives are the standard in CNC high-gloss machining. The high-gloss diamond cutting edge cannot see any notch burrs under a high-power microscope, and it can withstand long-term cutting without deformation. The coefficient of friction between diamond and non-ferrous metals is very small, chips are not easy to stick to the blade, and built-up edge will not occur. Therefore, the cutting edge is always directly tangential to the workpiece during machining, and stable dimensions and high brightness can be obtained.

Workpiece: Materials suitable for high-gloss processing include aluminum and copper. When processing aluminum and aluminum, the brightness is the highest, and the wear on the tool is the least; when processing copper, the brightness is relatively bright, and the wear of the tool is second.

Process: The cutting speed of mirror milling is generally around 30m/s. In order to be able to process a perfect workpiece, the spindle must be dynamically balanced after a tool change to minimize fluctuations caused by the dynamic imbalance of the workpiece surface. Diamond tools have good thermal conductivity, and the cutting volume of high-gloss processing is not large, and generally do not need to add coolant.

Application: The trend of hardware highlight processing is obvious. Aluminum highlights are mainly used in 3C industries such as mobile phones, digital product casings and some aluminum plates. And after highlighting, secondary oxidation can be carried out to enhance the wear resistance of the highlighting area.

(1) Processing materials: acrylic, plexiglass, copper alloy, copper parts, aluminum alloy, aluminum material, die-casting aluminum parts, aluminum parts, copper alloy, copper parts, magnesium alloy, zinc alloy, acrylic, etc.

(2) Machined parts: watch case, mobile phone frame, mobile phone case, TV case, camera focusing hardware highlight, mobile phone keypad, mobile phone camera, mobile phone middle frame, ring, pendant, speaker, digital camera, 3D complex hardware, hardware decorative film Wait;

The superhard diamond tool can effectively remove the burr and beryllium front around the workpiece, and the processing quality is good, so that the processed product can achieve a perfect mirror effect.

3. Advantages of diamond high-gloss cutting tools

(1) The surface finish of the machine is high, and the cutting edge of the high-gloss diamond tool is sharp and precise, and the workmanship is fine. And the anti-vibration design can suppress vibration during processing and enhance the stability of parts during processing. Greatly improve the quality of the processed surface, so that the surface is free of scratches, the tool angle and handle diameter can be customized according to customer processing needs!

(2) In high-speed processing, especially in high-gloss processing. Products processed by super-hard diamond high-gloss tools have a high finish and no burrs, white lines, or black spots on the surface. And the tool life is long, which is 20-100 times that of ordinary tools, which saves the time for frequent tool changing and tool setting, and ensures the consistency of processing.

(3) The processing efficiency is high, and the speed can reach (5000-100000r/min). The processing efficiency is greatly improved, the processing cost is reduced, and generally no cutting fluid is used, which is environmentally friendly and reliable.

4. Ultra-precision diamond highlight cutting tool

(1) Optical tools: diamond ultra-fine tools, mainly used for optical processing with nanometer precision, to achieve optical-level processing mirror surfaces: such as high-precision optical lenses, spectacle lenses, contact lenses, digital electronics industry, automotive industry, aerospace industry, Medical industry and other optics. Excellent performance, high hardness and wear resistance, low coefficient of friction, high modulus of elasticity, high thermal conductivity, low coefficient of thermal expansion.

(2) Acrylic knife: single crystal diamond highlight knife, chamfering knife, etc. It is mainly used for edge trimming of organic sheets such as acrylic, plexiglass, light guide plate, and high-gloss mirror light transmission effect. It can also be used for polarizers, backlights and plexiglass frosted edges. Requires use on cutterheads that have been balanced on a diamond polisher.

(3) 3C high-gloss cutting tools: diamond chamfering cutter, arc milling cutter, ball end milling cutter and diamond blade. Mainly used in 3C industries such as processing. High light efficiency, high surface finish of the workpiece to be processed, no patterns, white lines, and black spots on the surface, bringing huge market opportunities for high-gloss processing of mobile phone metal.
