ALLOY
A metal made by combining two or more metallic elements. An alloy typically possesses qualities different from those of the components used to create it.
ASM
Stands for American Society for Metals. ASM International is the world's largest association of metal material engineers and scientists. The association engages and connects materials professionals and their organizations to the resources necessary to solve problems, improve outcomes, and advance society.
ASTM
Stands for American Society for Testing and Materials. ASTM International is a not-for-profit organization that develops standards for materials, products, systems, and services. Metal with an ASTM designation meets the international standards for quality and regulations.
CUT-TO-LENGTH
This process levels coil into a flat sheet or blank. The service provides better length and width tolerances than sheared product, and it can improve diagonal tolerances as well.
DEBURRING
Cutting metals can leave behind burrs, which are unwanted raised edges or protrusions. Deburring is the process of removing these burrs with a tool.
DRAWING
Drawing is a metalworking process that uses tensile forces to stretch metal. As the metal is drawn, it stretches thinner, into a desired shape and thickness.
DRAWING TEMPERATURE
Drawing is usually done at room temperature, classifying it as a cold working process. However, it may be performed at elevated temperatures during special applications like on large wires, rods, or hollow sections in order to reduce forces.
ELONGATION
A metal fabricating term that refers to the degree to which a material can be bent, stretched, or compressed before rupturing. A metal's elongation is a point between tensile strength and yield strength, and it is typically expressed as a percentage of the original length.
GAUGE
The thickness of sheet metal in the USA is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal.
HEAT LOTS OR HEAT NUMBER
A heat number is an identification number that is stamped on a material plate to prove it meets industry quality standards which require materials to be tested by the manufacturer. The heat lot or heat number is used to identify production runs for quality control purposes.
EDGE ROLLING
Edge rolling is the process of adding finishing edges to metal. It forms the edge of a strip to the desired shape beyond that of a standard slit edge.
MIL STD
Stands for Military Standard. This classification establishes uniform engineering and technical requirements for military-unique or substantially modified commercial processes, procedures, practices, and methods. In order to qualify, materials have undergone rugged, exact testing, equal to the exigencies of combat use.
NORMALIZING TEMPERATURE
Normalization is a heat treatment that relieves stress on steel to improve ductility and toughness in steel that may harden after the cold working process. During normalization, steel is warmed to a temperature just above its upper critical point. Normalized heat treatment facilitates a more uniform final product.
ROCKWELL SCALE
The Rockwell Scale indicates the hardness of materials. Rockwell hardness numbers are most often used to describe the hardness of metals, although they are also used for some plastics. The Rockwell scale is based on measuring the depth of the indentation made by pressing a diamond point into a material.
SAE
Stands for Society of Automotive Engineers. SAE International is a global association of engineers and related technical experts in the aerospace, automotive, and commercial-vehicle industries. Materials meeting SAE standards are internationally recognized for safety, quality, and effectiveness.
SLITTING
Slitting is a precise shearing process, but instead of making cuts at the end of a workpiece like shearing, slitting cuts a wide coil of metal into a number of narrower coils as the main coil is moved through the slitter. During the slitting process, the metal coil passes lengthwise through the slitter's circular blades.
TEMPER
Temper refers to reheating hardened, normalized, or mechanically worked steel to a temperature below the critical range to soften it and improve impact strength. Tempering results in greater toughness by decreasing an alloy's hardness.
TENSILE STRENGTH
The maximum stress a material will withstand before fracturing or breaking. The ultimate tensile strength is calculated from the maximum load applied during the test, divided by the original cross-sectional area.
UNS DESIGNATION/NUMBER
Stands for the Unified Numbering System for Metals and Alloys. UNS designation provides a means of correlating internationally used metal and alloy numbering systems currently administered by societies, trade associations, and those individual users and producers of metals and alloys. This system is meant to avoid the confusion caused by using more than one identification number for the same metal or alloy, and the opposite situation of having the same number assigned to two or more different metals or alloys.
YIELD STRENGTH
The amount of stress a material can withstand before causing permanent deformity.
Hydraulic presses
Hydraulic presses use liquid pressure to release energy and valves to increase or decrease the pressure of the liquid in the chamber. Hydraulic presses are more common than other types, but on the other hand, hydraulic presses are the most powerful industrial metal stamping machine. the machine can apply 75,000 tons of power or even higher. The principle of operation is that the fluid can be injected or reduced upward or downward, depending on the fluid pressure, changing the pressure to make the piston rise or fall.

Mechanical presses
There are more types of machines for mechanical presses, which convert the rotational force of the motor into pressure acting on the object. Mechanical presses are characterized by the rapid and continuous application of pressure over a limited distance and are usually used for metal forging or sheet metal processing. Mechanicalindustrial metal stamping machine presses can reach up to 12,000 tons.
Screw presses
By rotating the screw, the energy of rotation is driven and pressure is applied. Screw presses run slowly and can produce large, constant forces.
Presses can meet the needs of mass production with fast turnaround, high quality and low cost. Choosing the right type of stamping press for different needs will make forging easier.
Accuracy requirements of industrial metal stamping machine body
The rigidity and stability of the machine body is a major influence on the accuracy of the press.
Industrial metal stamping machine is affected by processing technology and post-processing difficulty, casting body can only be applied to small tonnage punch and high-speed precision punch, cast steel body construction.
In terms of accuracy only, both types of bodies can guarantee the accuracy requirements of the machine, which only differs in their application range due to their respective special properties.
Quality of the assembly process
The quality of the assembly process directly determines the accuracy of the industrial metal stamping machine.
Fifty percent of the success or failure of an industrial metal stamping machine is due to the assembly process.
The stamping and forming process generates a lot of heat during the stamping process, and this heat can deform the workpiece, thus seriously affecting the accuracy of the workpiece.
Therefore, when selecting a stamping oil, it is important to consider both the lubrication and cooling properties as well as the extreme pressure and anti-wear properties of the stamping oil.
View maintenance requirements for industrial metal stamping machines
The maintenance condition of an industrial metal stamping machine also affects the accuracy of its precision.
Good maintenance can restore and maintain its high accuracy, which is very important for a company's normal production.
A good industrial metal stamping machine is not only of good quality, but also has a strong technical support from the manufacturer of the product, which helps the customer to get timely help and maintenance.
