Precision metal stamping refers to a manufacturing process that uses machinery equipped with dies to convert flat sheet metal in a coil or blank form into the desired components. It comes with unique features ideal for a particular process, which is sought-after in a wide range of industries, including the automotive field. The popularity lies in that this technology enables companies to develop large quantities of products and parts with high accuracy and precision.

 

In addition to that, enterprises can enjoy the advantages of using precision metal stamping, like cost-effectiveness, consistent quality, and accuracy. This article will discuss the best practice in precision metal stamping. Let’s begin!

Different Types of Stamping Die in a Punch Press Machine

 

1.        Lathe

In the precision metal stamping for hard materials, a lathe machine comes in handy. As one of the most extensively used machine tools, it helps remove undesirable metal from a workpiece to give a required shape or size.  A variety of products can be made from the lathe machine, such as nuts, bolts, pistons, ram, pump parts, etc. ^[1]

 

2.        Boring mill

Based on the types, the boring mill machine can be categorized as the horizontal and vertical boring mill. It is used to create smooth and accurate holes in a variety of materials, including metal, especially in sheet metal pressing. The working principle of the boring mill machine is that it utilizes a single-point tool with a cutting edge to enlarge existing holes.

 

The following merits make it one of the most sought-after machine tools applied to precision metal stamping.

l  Handle extremely large parts easily.

l  Reduce the likelihood of tool deflection.

l  Be durable with a longer lifespan. ^[2]

 

3.        Milling machine

A milling machine is widely used in many industries to manufacture high-precision parts in different shapes and sizes. It is featured with rotating cutters symmetrically arranged about its axis. As to its usage, it can handle flat and irregularly shaped surfaces. Also, it can drill, bore, and cut gears, threads, and slots. ^[3]

 

4.        Drilling machine

The drilling machine is another machine used in precision metal stamping worth checking out. It is a kind of machine in which the holes are being made on the workpiece by using a rotating tool called the drill bit or the twist drill. It serves as a tool to make holes of various sizes in a workpiece. With its simplicity and accuracy, it comes in handy in most manufacturing setups and production rooms, so it is especially acclaimed in the manufacturing industry. ^[4]

 

5.        Contouring machine

Sometimes grinding and cutting machines produce surface disparities or roughness, which can hardly be distinguishable by touch or vision. However, the degree of roughness can seriously affect the performance of the workpiece. The contouring machine contributes to assessing the surfaces of workpieces so as to ensure the high precision of the processing equipment and avoid recurrent production of parts and products with subpar performance.

 

6.        Grinding machine

A grinding machine comes integrated with an abrasive wheel used to remove rough surfaces on metal and make light. As a result, it is helpful in the production of smooth surfaces and accurate shapes and dimensions. ^[5]

 

7.        Wire cutting machine

A wire cutting machine is used in many industries to cut a variety of wires and flexible tubing to certain lengths. People can program the machine to cut wires or cables to a specific length. Apart from wires, the tool can cut glass optical fiber, insulated cable, copper tubing, etc. ^[6]

 

 

Three Types of Stamping Dies

There are a variety of ways of hardware processing. Stamping will be the common choice when the amount of parts is large, and the accuracy is relatively high. Stamping products have stable size, are lightweight, and have a good surface state and accuracy. Because they rely on punch and die, so the production cycle is long, and the initial die investment is large. There are three common types of stamping dies:

 

1.        Single die - Only one process can be completed, and then it requires manual feeding in the process of stamping.

2.        Continuous die - Also called as “progressive die” in the stamping process of a stroke. This type of die will complete two or more stamping processes at the same time in one stroke of stamping.

3.        Composite mold - Multiple materials can be carried out at the same time, or multiple processes can be carried out simultaneously.
