Buying Guide for Various Metal Cutting Machines

introduction

In construction and manufacturing, cutting tools are indispensable.

When it comes to metal processing, the first thing that comes to mind is cutting machines. Metal cutting machines generally refer to cutting equipment that cuts materials such as steel, iron, aluminum, and copper, among which steel is the most common.

Metal cutting machines, whether fixed or portable, are often used in workshops or construction sites.

There are a wide variety of cutting machines on the market, such as angle grinders, aluminum cutting machines, and metal cutting machines.

In this article, we will briefly introduce the characteristics and application scenarios of these machines, as well as a purchasing guide.

• Conclusion

Traditional cutting mostly uses angle grinders, aluminum saws and ordinary steel cutting machines. Among them, the angle grinder is very flexible and suitable for cutting thin parts, and the steel cutting machine is suitable for large or thick parts. In large cases, industrial-specific cutting equipment is required.

Angle Grinder

1. Features: fast RPM, many types of discs, flexible cutting, poor safety
2. Category: (size, motor type, power supply method, brand)
3. Lithium battery brushless angle grinder:
   low noise (compared to brushless, the noise is actually not too small), adjustable speed, flexible and convenient, and safer than wired.

An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing. Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.

The abrasive disks for these saws are typically 14 in (360 mm) in diameter and 7⁄64 in (2.8 mm) thick. Larger saws use 410 mm (16 in) diameter blades.

Application

Angle grinders are standard equipment in metal fabrication shops and on construction sites. They are also common in machine shops, along with die grinders and bench grinders.

Angle grinders are widely used in metalworking and construction, emergency rescues.

Generally, they are found in workshops, service garages and auto body repair shops.

Note

The use of angular grinder in cutting is not preferred as a large amount of harmful sparks and smoke (which become particulates when cooled down) are generated when compared with using reciprocating saw or band saw.

How to Choose

The saw is Commonly used with Wood，and can be found in various models and sizes.
Miter saws are capable of making straight, miter, and bevel cuts.

Aluminum cutting machine

1. Features: Special for aluminum alloy, the saw blade can be replaced to cut wood.
2. Category: (size, motor type, power supply method, brand)
3. Operation method：There are pull-rod ones and push-down ones. Pull-rod ones are the best.

Some machines can cut at multiple angles, and some can only cut vertically. Depends on the type of machine

Metal Cutting Machine

1. Features: Generally, it cuts mostly steel. The variable speed saw blade can cut a variety of materials, both soft and hard.

2. Category: (size, motor type, power supply method, brand)

Here’s a comparison of cold cut saws and regular metal cutting machines

Ordinary cutting machine

Ordinary cutting machine: It uses a Abrasive saw, which is cheap but not durable. It eats the saw blade, causing a lot of pollution, dust and noise.

An abrasive saw, also known as a cut-off saw or chop saw, is a circular saw (a kind of power tool) which is typically used to cut hard materials, such as metals, tile, and concrete. The cutting action is performed by an abrasive disc, similar to a thin grinding wheel. Technically speaking this is not a saw, as it does not use regularly shaped edges (teeth) for cutting.The saw blade is slightly more expensive, but it can cut many more times than the resin saw blade. It is not expensive in total. It has fewer sparks, less noise, less dust, high cutting efficiency, and the cutting speed is three times that of the grinding wheel blade. The quality is very good.

Cold Cut Saw

The saw blade is slightly more expensive, but it can cut many more times than the resin saw blade. It is not expensive in total. It has fewer sparks, less noise, less dust, high cutting efficiency, and the cutting speed is three times that of the grinding wheel blade. The quality is very good.

One thing to be wary of is the rated RPM differences between abrasive wheels and cold saw blades. They can be quite varied. And then more importantly, there are many differences in RPM in each product family depending on size, thickness and type.

Difference Between Cold Cut Saws and Abrasive Saw

1. SafeVisibility should be a major focus when using a sand saw to avoid any potential eye dangers. Grinding blades produce dust that can cause lung damage, and sparks can cause thermal burns. Cold-cut saws generate less dust and no sparks, making them safer.
2. ColorCold cutting saw: the cut end surface is flat and as smooth as a mirror.Abrasive saws : High-speed cutting is accompanied by high temperature and sparks, and the cut end surface is purple with many flash burrs.

Tips of Use

On the machines listed above, their main differences are size and purpose.

Whatever on a frame or portable,There’s a machine for every type cut.

• Material to be cut: The choice of machine depends on the material you intend to cut.
  Such as, metal cutting machines, plastic cutting machines,wood cutting machine.

• Cost: Consider the purchase cost of the equipment, the cost per unit part or unit cut.

Conclusion

Traditional cutting mostly uses angle grinders, aluminum saws and ordinary steel cutting machines. Among them, the angle grinder is very flexible and suitable for cutting thin parts, and the steel cutting machine is suitable for large or thick parts. ## Conclusion

In large cases, industrial-specific cutting equipment is required.

If you are looking for convenience on a small scale, you can use an angle grinder.

If it is used in a factory or workshop, cold sawing is more recommended. It’s safer and more efficient.

Cold Saw is unique in the field of metal cutting with its cold cutting technology. The use of cold cutting technology not only increases the cutting speed, but also ensures high-precision cutting results, which is especially suitable for scenes that require high material performance.
