Standard measurements apply to both sheet sizes and thicknesses. Thus, steel sheets have high tensile strength and durability suitable for use in constructions and machinery.Īt the same time, copper sheets often find use as a decorative layer on modern buildings. Metal sheets have the same mechanical properties as the base metal. Choosing the right one for you comes down to the application and requirements of your product. Some of them are carbon steel, stainless steel, copper and aluminium. Pretty much all the common engineering metals are also used in the form of sheets. That is why we see it everywhere around us.Īt the end of the article, we will be discussing different forming methods used with sheet metal. At a relatively cheap price, it makes a great fit for most engineering purposes. The thin sheet metal is easy to form, while still providing great strength. The thickness of sheet metal starts from 0.5 mm and goes up to 6 mm. The thickness of foil is usually up to 0.2 mm. Metal foil is especially common with aluminium, often referred to as tinfoil. For our purpose, we are going to stick with millimetres as the unit of measurement. Having gone over the primary measurement systems, we can now look at the categorisation of foils, sheets and plates. A higher gauge number means a smaller thickness.Īs it is related to the weight of a metal, the actual thickness (mm) for the same gauge, is different for various metals (e.g. Gauge represents the thickness of a metal in relation to its weight per square foot. Although official standards discourage the use of gauges, they are not all that rare. Gauge is another unit for measuring sheet metal thickness. As the British often use “mils” as a plural for millimetres, it can be a little confusing but the difference is important. One mil equals to a thousandth of an inch. While millimetre is a pretty straightforward unit, mils and gauges are only common in engineering and manufacturing. Thickness is measured in 3 ways – millimetres, mils and gauges. Millimetres, Mils & Gaugeįoils, sheets and plates are pretty much the same, with the only difference being in thickness. There are other measurement units used to categorise metals by thickness, though. Sheet metal is any metal that has a thickness in between 0.5…6 millimetres. Sheet metal is one of the shapes and forms metal can be bought in. Since the H500 series inverter was introduced to the market, it has excellent low-frequency torque, fast acceleration and deceleration, ultra-high speed stabilization accuracy, and ultra-high cost performance.V Forming Processes for Sheet Metal What Is Sheet Metal? China has surpassed Germany to become the world's largest machine tool market, and CNC machine tools have become the mainstream of machine tool consumption. Strong, constitutes a huge demand for the machine tool market, especially CNC machine tools. Coal, automobile, steel, real estate, building materials, machinery, electronics, chemical industry and a number of high-growth industries based on heavy industry are developing momentum. If you use inverter and motor to achieve high performance, please follow the following to perform inverter self-learningĪt present, my country is in the middle stage of industrialization, that is, it is gradually transforming from opening up to solve shortages to building an economic powerhouse. Remarks: If necessary, connect an external braking resistorĠ3. If the stopped spindle rotates, the starting voltage of P9.08 braking unit action should be reduced. The following takes H500 series inverter as an example to explain the application in high-speed spindle punching machine (inverter self-learning is performed first before trial operation, refer to the attached picture at the end of the text) N Low noise, small vibration and long life. L Short acceleration and deceleration time: fast start and stop K Under intermittent load, the motor speed fluctuation is small J Wide speed regulation range and high speed stability The performance requirements of the machine tool for the spindle drive are as follows: The basic control is the forward, reverse and stop of the main shaft, which can realize automatic shifting and stepless speed regulation.Īt present, the spindle control device in the machine tool usually uses an AC frequency converter to control the AC spindle motor. Among them, the spindle operation is one of the important contents. CNC machine tool is a typical product of mechatronics, which is an automatic equipment integrating machine tool, computer, motor and its driving, automatic control, detection and other technologies.
