No matter how long your mechanical cable application requires, all cables will eventually be cut. In most cases, the cutting length is terminated with accessories such as balls and handles, eyelets, or threaded plugs. But in other cases, simply cut and install the cables. Regardless of your mechanical cable requirements, you need to cut the cable. No matter what application requirements you need to meet, how you cut mechanical cables completely depends on the materials you use to build the cables themselves.
Mechanical cables made of stainless steel or galvanized steel can be mechanically cut using a cutting machine or Felco cable cutter. In most cases, using stainless steel and galvanized steel, a single wire in a cable will not wear during mechanical cutting. Usually, smaller cables (less than 3/64 inches in diameter) typically used for medical devices and even medical implants cannot be mechanically cut without wear and tear. Mechanical cutting of such cables may cause individual wires to become loose, which may expose the loose wires to the human body or hinder the normal operation of surgical instruments. Therefore, this type of micro mechanical cable should be electrocutted to fuse the cutting ends together to form a welding end.
However, tungsten is a refractory metal that can withstand higher temperatures than steel and requires additional steps to prevent end separation.
Although stainless steel is commonly used in mechanical cable components in many medical devices today, tungsten is becoming the preferred mechanical cable material in the field of surgical robots. Due to the fact that tungsten cables are usually smaller than human hair, it is crucial to understand the complex methods of cutting tungsten cables.
Electrocutting tungsten
Tungsten has the highest melting point among all metals known to humans, making it an ideal choice for variable heat. However, in the case of cutting tungsten cables, simply electrocutting them is not feasible because what usually happens in the fused part of the electrocutting process is not enough to bond the wires together. Due to the melting temperature of tungsten being higher than the temperature generated by electric cutting, an extremely brittle seal can only be achieved at the end of the cable. Due to this brittle sealing, it requires further processing of the cable to achieve effective welding ends.
The preferred method for melting the ends of tungsten cables is plasma welding, which will provide effective sealing and prevent cable wear. The generated plasma end can be circular to provide easy assembly into component equipment. This method has been proven to be a reliable method for achieving adhesive ends.

When using tungsten wire ropes, the following points should be noted
1. The weight of the single crystal rod cannot exceed the rated working tension of the tungsten wire rope; 2. Before use, the appearance and surface quality of the tungsten wire rope should be checked first to see if there are any hard marks such as scratches, knots, and folds caused by hard objects. When winding the tungsten wire rope, the tightness should be checked to see if it is even and appropriate. If the above defects are found, immediately stop using them;
Tungsten wire: the perfect combination of surgical robots
Precision applications require precise materials, and tungsten wire rope is an ideal high-strength robot cable for precision applications. For decades, stainless steel has been the preferred metal for manufacturers who require elastic and corrosion-resistant materials, especially in humid environments. Stainless steel has high tensile strength and cost-effectiveness, making it the perfect choice for wires and cables that must withstand extremely harsh environments and working conditions. Stainless steel is valuable because it is durable and maintains its integrity. However, tungsten wire has become a darling of the surgical robot industry.
A single crystal furnace is a nonlinear load that consumes a large amount of electrical energy while generating high order harmonics during operation. Harmonic current causes serious distortion of voltage and current waveforms, which can lower power factor, decrease transformer utilization, overheat electrical equipment, and generate vibration and noise. Single crystal furnace harmonics can cause local parallel resonance or series resonance in the power system, amplifying the harmonic components and easily burning out compensation capacitors and other devices and equipment. Harmonics in the single crystal furnace can also cause misoperation of relay protection and automatic devices, leading to confusion in electrical energy measurement. The harmonic component can interfere with the crystal pulling control system, causing misalignment, crystal breakage, and other phenomena. In severe cases, it can cause tripping, affecting the safety of production and product quality.
