When an 18K gold cable chain needs to be cut into links 0.3 millimeters wide without any deformation or burrs, traditional cutting techniques are often at a loss. Shenzhen Alpha Technologies Co., Ltd. The newly launched Cable Chain Diamond Cutting Machine, with its "micron-level precise control + stress-free cutting" technology, is redefining the standards for processing precious metal cable chains.
The cutting philosophy from "head-on confrontation" to "softness overcomes hardness"
Precious metal alloys are like "delicate dancers". If too much force is applied, they will break; if not, they will slip. The engineers of Shenzhen Alpha described the processing difficulties in this way.
In view of the characteristics of materials such as platinum and K gold, which are prone to deformation and conduct heat quickly, the machine adopts three core technologies.
Super-hard diamond cutter wheel: The hardness of the cutter wheel reaches HV3000, far exceeding the hardness of metals, ensuring that "the knife does not become blunt and the metal does not melt" during cutting. Actual measurements show that when cutting platinum cable chains, the service life of the cutter wheel is 20 times longer than that of traditional tungsten steel knives.
Dynamic pressure compensation system: It monitors the cutting resistance in real time through sensors and automatically adjusts the pressure of the cutter wheel. A high-end jewelry brand has reported that this technology has increased the cut yield rate of 0.2mm fine chains from 65% to 92%.
Low-temperature cooling cycle: Nano-scale lubricating fluid is used in combination with a low-temperature airflow of -5℃ to prevent metal from deforming due to softening at high temperatures. "Previously, cutting K-gold chains required repeated annealing, but now they can be formed in one cut." " A cooperative craftsman sighed. Some customers call our machine "Metal Engraver". The product manager of Shenzhen Alpha smiled and said, "It can engrave patterns on metals as thin as a human hair and also ensure that the weight error of each link does not exceed 0.01 grams."
A breakthrough in scenarios from "single function" to "full material adaptation"
Shenzhen Alpha refuses to "cut for the sake of cutting". In response to the characteristics of the jewelry industry of "small batch and multiple materials", the machine has designed three major modes.
Precious metal mode: Specifically designed for platinum, K gold, silver, etc., the cutting speed is reduced by 30%, but the surface finish reaches Ra0.05μm.
Alloy mode: Compatible with hard alloys such as titanium steel and palladium, and reduces tool sticking through high-frequency vibration of the tool wheel.
Experimental mode: Open pressure, rotational speed and cooling parameters for designers to explore new metal materials. An artist used our machine to cut memory metal and made a necklace that could "dance". The marketing director shared.
The more groundbreaking feature is the "link mirror cutting" function. Through the AI vision system, the machine can automatically identify the direction of the chain links, ensuring that the cutting angles of each link are exactly the same. It used to take two hours to manually adjust the direction of the chain links, but now it only takes three minutes with a machine. The person in charge of a luxury brand factory said.
Shenzhen Alpha hopes to enable every gram of metal to blossom with design value
In the next three years, we want machines to "understand" the designers' sketches. The CTO of Shenzhen Alpha disclosed at a recent industry forum, "The 'intelligent Trajectory generation system' under development can automatically plan the optimal cutting path and even predict the risk of metal deformation simply by uploading a 3D model."
At present, this machine has passed the SGS "Precious Metal Processing Safety Certification" and has obtained five patents related to cutting accuracy. Tests conducted in collaboration with brands such as Cartier and Tiffany have shown that the cable chains processed by them perform exceptionally well in tensile strength tests, with no breakage after 100,000 bends. With the application of new materials such as 3D printed metals and aerospace-grade titanium alloys, Shenzhen Alpha is developing a "multi-material composite cutting module" and plans to launch an upgraded version that can handle gold, ceramics and carbon fibers simultaneously next year.
Cutting is not about destruction; it is about giving metal a second life. The founder of Shenzhen Alpha said, "When we cut a gold chain with an accuracy of 0.01 millimeters, we are actually engraving the trajectory of light." In the workshop of this Shenzhen enterprise, each machine is engraved with a line of small characters: "Treat every gram of metal with a sense of awe." This might be the modern interpretation of the "craftsman spirit" by "Made in China".
