Cutting Art _ Diamond High-Gloss Knife Milling Copper and Aluminum Alloy Parts for Mirror Surface Effect
Natural diamond high-gloss tool milling of copper parts, aluminum plates, etc. The ultra-fine turning technology for obtaining optical mirrors is a new process technology developed in the 1960s. It has been nearly 60 years old. In addition to the emergence of computer numerical control (CNC) super-precision lathes in recent years, CNC high-light processing has made a great breakthrough, making it possible to replace grinding by high-gloss milling.
First, Elements of CNC High Gloss Machining
In recent years, with the development of high-performance, high-precision CNC machine tools and excellent diamond tools. The CNC high-gloss machining process has made a great breakthrough, and high-gloss milling instead of grinding has been matured. The principle of CNC high-light processing is to use diamond high-gloss knives on the precision CNC machining equipment, with scientific and reasonable cutting parameters and processes to achieve the sparkling surface effect.
Summary of CNC high-light processing elements are as follows:
(1) Machine tool: Because high-light processing requires good rigidity and precision of the machine tool, the use of precision CNC machine tools is the prerequisite for high-light processing. Such as precision CNC engraving machine (the general speed is 20000~100000 rev / min);
(2) Tool: To achieve high-gloss effects, diamond high-gloss knives are required. Diamond high-gloss knives are standard for CNC high-light processing. The diamond high-gloss cutting edge can not see any notched burrs under the high power microscope, and can withstand long-term cutting without deformation. The friction coefficient between diamond and non-ferrous metal is very small, the chips are not easy to stick to the blade, and no built-up edge is produced. Therefore, the cutting edge is always cut directly to the workpiece during the machining process, and a stable size and high brightness can be obtained.
(3) Workpiece: Suitable materials 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 minimal; When processing copper parts, the brightness is relatively bright, and the wear of the tool is second.
(4) Process: The cutting speed of mirror milling is usually around 30m/s. In order to be able to machine a perfect workpiece, the spindle must be dynamically balanced after the tool change to minimize the ripple caused by the dynamic imbalance on the workpiece surface. The diamond tool has good thermal conductivity, and the cutting amount of high-gloss processing is not large, so it is generally unnecessary to add coolant.
(5) Application: The trend of high-gloss processing of hardware is obvious. Aluminum highlights are mainly used in 3C industries such as mobile phones, digital product shells and some aluminium sheets. And after the high light, it can be oxidized for the second time to enhance the wear resistance of the high light area.
Second, CNC high-light processing range
(1) Processing material: 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 focus hardware highlight, mobile phone button, mobile phone camera, mobile phone middle frame, ring, pendant, speaker, digital camera, 3D complex hardware, hardware decorative film, etc.;
Ultra hard diamond tools can effectively remove burrs and beryllium fronts around the workpiece, and have good processing quality, so that the processed products achieve perfect mirror effect.
Third, Advantages of diamond high-light cutting tools
(1) The surface finish of the machine is high, and the diamond high-gloss tool has sharp and precise cutting edge and fine workmanship. And the anti-vibration design can suppress the vibration during the machining process and enhance the stability of the parts during processing. Greatly improve the surface quality of the processing so that the surface is free from scratches, and the tool angle and shank diameter can be customized according to the customer's processing needs!
(2) In high speed machining, especially in high light processing. The products processed by super-hard diamond high-gloss knives have high finish and no burr, white line and dark spots on the surface. And the tool has a long service life, which is 20-100 times of the life of the ordinary tool, saving the time of frequent tool change and tool setting, and ensuring consistent processing.
(3) High processing efficiency, the speed can reach (5000-100000r/min). The processing efficiency is greatly improved, the processing cost is reduced, and the cutting fluid is generally not used, which is environmentally friendly and reliable.
Fourth, Ultra-precision diamond highlight cutting tool
(1) Optical Tools: Diamond superfine tool, mainly used for optical processing with nanometer precision, to achieve optical grade processing mirror: 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 friction coefficient, high modulus of elasticity, high thermal conductivity, low coefficient of thermal expansion.
(2) Acrylic cutter: Single crystal diamond high-light knife, chamfering knife, etc. Mainly used for trimming organic sheets such as acrylic, plexiglass, light guide plate, and high-gloss mirror surface translucent effect. It can also be used for polarizer, backlight and plexiglass matte edge processing. It needs to be used on the cutter head which has been balanced by the diamond polishing machine.
(3) 3C high-gloss cutter: Diamond chamfering cutter, arc milling cutter, ball end milling cutter and diamond blade. Mainly used in processing 3C industry such as aluminum alloy mobile phone casing. With high light effect, the surface finish of the machined workpiece is high, and there are no patterns, white lines and dark spots on the surface, which brings huge market opportunities to the high-gloss processing of mobile phone metal.
