As mentioned earlier, cold cutting refers to an assortment of techniques used to precisely cut different metals without heating them. This means that various types of cold-cutting techniques have been developed and perfected over the years. One such method is using a saw, which could be either an oscillating blade or a circular sawing machine. A circular-cutting machine, such as a bandsaw, is quite popular because of the flexibility it offers when cutting different types of materials.
Another extremely popular cold-cutting method is abrasive cutting, usually performed using an abrasive saw. The process uses an incredibly tough blade embedded with many small abrasive particles. The particles work together to slice through the material, delivering a clean and precise cut.
Shearing is another widely used cold cutting technique in industrial settings. It entails using a cutting tool, like a shear, to make straight cuts on a piece of metal material. This tool is often used to cut thin sheets and strips within an approximate thickness range of 2 to 3mm.
Water jet cutting refers to a computer-controlled cold-cutting technique that manufactures metal parts precisely. As the name suggests, this cutting technique uses high-pressure water jets to make cuts on different types of materials, including metal ones. If the material being cut is metal that's tough and thick, cold cutting by water jet may involve adding some abrasives to the water stream to deliver a better and cleaner cut.
Cryogenic Cutting is more of a method of cutting very large appliances or items used in heavy-duty industrial applications, like cryogenic processing. In this method, extremely low temperatures are applied to create a fracture on the material to be cut. This makes it easier to cut through tough, thick pieces of metal.
Laser cutting is a more modern method that falls under the category of cold-cutting techniques. This technique uses a high-energy laser to cut through various materials precisely. Laser cutting remains the most popular cold-cutting technique for creating intricate and precise shapes on metal sheets and plates. In fact, manufacturers use laser cutting to create most of the modern appliances and devices in the world today.
Material
Copper: The performance of cold cutting copper pipe is quite excellent, coupled with a certain anti-mildew antibacterial ability, which can realize the healthy and hygienic use of the family.
Size
Generally, it has two types—1/8'' to 1/4'' and 3/8'' to 1/2'' . Usually, one type is able to 1/4'' - 3/8'' and another one is able to 1/8'' - 1/4'' . Also, the sizes can be customized according to different needs.
Pipe Types
Steel: Generally speaking, cold cutting machine can cut cold-rolled steel pipes, including carbon steel pipes and alloy steel pipes.
Copper: There are various types of copper pipes, such as water pipes, air conditioning pipes, and gas pipes. Different types of copper pipes have different specifications and characteristics.
Plastic: Plastic pipes can be divided into PVC pipes, PP pipes, and others. The material and characteristics of each kind of plastic pipes are different, so they need to be adapted to different cutting methods.
Maximum RPM
It varies per product. Generally, when the motor power is 1.5-3.0, the maximum is about 95-110.
1. Regular cleaning and maintenance of the machine is the most important part of the cold cutting machine. Remove cutting waste and dirt in time, and clean and disinfect them to prevent the machine from getting dirty and damaged.
2. Regularly lubricate parts of the machine. Apply an appropriate amount of lubricating oil to each moving part, keeping it smooth and reducing friction and wear, which can extend the service life of the machine.
3. Regularly check the parts of the machine. Check whether the cutting blades, fasteners, and bearings are loose or worn. If faults or potential problems are found, they should be resolved promptly to avoid affecting the normal operation and cutting quality of the machine.
4. Pay attention to the use of the cold cutter. Use suitable materials and cutting speeds as per the machine's requirements. Avoid overloading and over-speeding use to prevent damage to the machine.
Several industries use cold sawing techniques to cut metal. Here are some examples:
Metalworking Shops:
Metalworking shops use cold cutting to make precision cuts. They use it on various materials such as brass, copper, steel, and aluminum. The cuts don't have burrs that are mostly common with other cutting methods. Metalworking shops can use sword or chop saws as cold-cutting equipment.
Manufacturing Industry:
The manufacturing industry uses the cold cutting process to make clean and accurate cuts on metals. The industry also benefits from faster production rates and less equipment wear.
Construction Industry:
In the construction industry, cold cutting is used to cut various structural steel components. Also, it's used to cut metal piping and fabrication components. Water-cooled rotary saws are popular cold cutting methods used by the construction industry because they increase productivity on construction sites.
Automotive and Aerospace Industries:
The automotive and aerospace industries employ the cold cutting process to cut metals with high levels of accuracy. It's also used to produce high-quality components. These industries use a laser beam cold cutting technique for its accuracy and efficiency when cutting metal.
Signage and Display Companies;
Signage and display companies use a cold cutting technique to cut and create precision signage. The displays match the clients' specifications. Also, these companies use the method to achieve a clean cut and neat edges without damaging graphic materials.
HVAC Industry:
The HVAC industry uses cold cutting when working with insulation on the pipes or ducts. It mostly uses a pipe cutter tool for its cleanliness and minimal disruption.
Buyers looking for cold cuts in bulk should consider a few things before making an order. To begin with, who will be using the cold cut saw? If it's going to be used for industrial purposes, then a machine with advanced features and a powerful motor will be necessary. Such a machine would be able to handle high volumes with ease. It would probably have a big cutting deck, beefy blades, and a sturdy build.
For occasional use, a compact and portable saw would be sufficient for cutting cold meat. This type of saw comes with a lightweight design so that it is not difficult to store when not in use. Additionally, it has lower power requirements compared to its industrial counterpart. Also, it would be more affordable because it is intended for home or light use.
The second thing buyers should consider is the types of meats the machine is designed to cut. Some saws are cold cuts that are ideal for cutting through bones and frozen meats, while others are suitable for just meat with no bones. As such, buyers should get a machine that can cut through the particular meat they intend to process.
Also, buyers should pay close attention to the saw's cutting capacity and size to ensure it can handle the anticipated volume of meat. The dimension of the saw also matters. Therefore, buyers might find it necessary to store the saw cold in a particular place. If this is the case, then go for a machine that will not take too much storage space.
When making a bulk order, the buyer should consider the price and gauge whether it matches the features and specifications of the machine. Go for machines that offer high value at a reasonable price.
Finally, read the reviews of previous users to gauge the performance and satisfaction of the machine being considered for purchase. Pay attention to the comments regarding durability, ease of use, cleaning, maintenance, and customer service support. Once the reviews are in, make a decision and place the order with confidence.
Q1: What materials can be cold cut?
A1: As previously mentioned, various materials can be cold cut. Some examples include metals like steel, copper, cast iron, aluminum, plastic, PVC, and ceramic.
Q2: What are the limitations of cold cutting?
A2: The absence of heat is one of the greatest benefits of cold cutting. However, this absence can also make it more difficult to cut particular materials. Cold cutting is not appropriate for materials with a high tensile strength that need a cutting tool with a higher temperature, like diamonds.
Q3: What is the difference between cold cutting and hot cutting?
A3: The process of cold cutting does not involve heating the material before cutting it. This is in contrast to hot cutting, which requires cutting tools that are heated to raise the energy of the molecules in the material so that they can be easily cut through.
Q4: Does a cold cut increase the risk of cracks?
A4: Cold cuts are not jagged, so there is no increased risk of cracks developing. The smooth edges produced by cold cuts generally reduce the crack risk.
