Rainbow Jewelry Finish with Conprofe Ultrasonic Machining
There are various machining approaches for metal jewelry surface, including chasing, hammering, wire drawing, sandblasting, embossing, laser engraving and electroplating. These unique machining methods not only enhance the texture and aesthetic appea
Today, we present a brand-new perspective of metal jewelry machining, which is machining metals surface with Conprofe Ultrasonic Technology, thus achieving a dazzling and vibrant rainbow-like effect and showcasing brilliant colors.
During machining, the Ultrasonic Machining System transforms high-frequency electrical energy into mechanical vibrations and applies a vibration frequency of 16 to 60 kHz per second to the MCD (Monocrystalline Diamond) tool, leading to periodic separation between the cutting tool and the workpiece and nano grooving patterns on the workpiece surface. The pattern as a grating structure reflects vibrant rainbow-like hues under the light by dynamically adjusting the spacing and angles of the grating, thus creating a unique and vivid visual effect.
Now let’s take a look at Conprofe’s solution!
Workpiece: Gold
The workpiece material for this machining is gold, and the current encountered challenges are as follows: Traditional scraping techniques can only be applied to simple flat or linear surfaces, and the processed workpiece surfaces are rough with less pronounced color effects.
In response to this, Conprofe has innovated the machining technique by combining the Conprofe Ultrasonic Machining System with MCD tool. Conprofe Ultrasonic Machining Technology enables not only the machining of complex and multi-dimensional surfaces but also effectively improves surface quality, achieving more dazzling and vibrant color effects.
Conprofe Ultrasonic Machining System
Advantages:
Significantly lower cutting forces and cutting temperature
Less subsurface damage and cutting stress to hard-and-brittle materials
Lower surface roughness
Longer tool life
More consistent workpiece surface
MCD (Monocrystalline Diamond) Tool
Features
Less roughness with mirror-like effect in machining nonferrous metals.
Longer tool life for its high hardness and excellent wear resistance.
Less friction, deformation and built-up edge and lower cutting force thanks to sharper cutting edge.
Higher thermal conductivity and lower coefficient of thermal expansion, beneficial for the precision component machining.
Machining Advantages
Compared to the customer's original machining solution, Conprofe Ultrasonic technology has improved surface quality with Ra roughness < 0.8μm. Moreover, the brightness, reflection and color effects on the workpiece surface all meet the customer's expectations for the its appearance. Additionally, apart from gold, this unique machining technique can also be applied to various metal materials such as silver, aluminum alloys, etc.
