How to cut the common material of concave-convex mould by WEDM? New solution

As a high-precision machining method ofwire erosionThe technology has gained wide use in the manufacturing industry. One of the most important applications of WEDM is the machining of dimple and convex moulds. ZK CNC will provide you with detailed information on the steps, techniques and points to note when machining dimple moulds with WEDM to ensure that you can achieve this task efficiently and accurately.

I: Understanding the basic concepts of concave and convex moulds

Before we start to talk about WEDM, including concave and convex dies, we need to understand the basic concept of a concave and convex die. Concave and convex dies, also known as stamping dies, are tools that are used for stamping, forming, and other processing operations on sheet metal or other materials. A concave die is the part of the workpiece that is raised, while a convex die is the part of the workpiece that is recessed.

II: Steps for machining concave-convex moulds by wire cutting

Prior to wire EDM, CAD drawings of the concave and convex moulds should be accurately designed to ensure that they are accurate and cover all dimensions, hole diameters and angles.

2. Selection of suitable materials, according to the needs of the use of concave-convex moulds to choose the appropriate material, in general, the kind of high hardness and good wear resistance of the tool steel is used for the production of concave-convex moulds of the commonly used materials.

First of all, to carry out the preparation of wire cutting machine tools, to ensure that its worktable is clean, in line with the requirements of levelling, then, the need for the position of the cutting head to be accurately adjusted, but also to do a good job on the angle of its accurate setting, so as to ensure the accuracy of the cutting.

Here, there is a situation that must be mentioned, that is, in the concave-convex mould processing process, there is the problem of moving the axis to get scrap, for the traditional practice, is to dismantle the molybdenum wire to achieve the shift, or manual way to move the Z-axis, this way is not only inconvenient, and in terms of accuracy is prone to error, and now it is, a new technology, which can solve this difficult problem, this technology does not need to manually operate the machine, do not need to dismantle the screw locking, and its accuracy can reach 0.01 microns. Can solve this difficult problem, this technology does not need to manually operate the machine, do not need to dismantle the molybdenum wire, do not need to lock the screw, and its accuracy can reach 0.01 microns.

Preparation for processing parameter setting: Firstly, the processing parameters of the WEDM machine should be set according to the selected material and the mould design, and the processing parameters mentioned here cover the cutting speed, electrode diameter, pulse frequency and so on.

The first step in the process is to import the CAD drawings into the control system of the WEDM machine. Next, the machining process is initiated, during which it is important to ensure that the operator remains focused and that the quality of the machining is monitored at all times.

6. Cleaning and checking: After machining is completed, the surface of the concave-convex mould is quickly cleaned of any residues, and a visual and dimensional check is carried out to ensure that the quality of the machining meets the requirements.

III: Factors affecting the price of wire EDM concave and convex moulds

In terms of material costs, the price of the material chosen for the concave and convex moulds will have a direct impact on the processing costs. Generally speaking, the price of those tool steels with higher hardness is relatively high.

It affects the difficulty of machining, it affects the machining time, and it affects the price, because the complexity of the design structure of the concave-convex mould and the need for high-precision machining all play a role in it.

In terms of processing scale, the number of orders will have a direct impact on the utilisation rate of the production line, which in turn will affect the processing price of a single piece of concave and convex mould.

4. Requirement of machining accuracy: If the concave and convex moulds have a very high requirement of machining accuracy, it is necessary to use high-precision wire-cutting machine tools, which will increase the cost of machining.

5. Processing cycle: the processing cycle to be considered, covering the design process, as well as the processing process, as well as the inspection process, etc., in a short period of time to complete the processing, generally speaking, need to add the input of workers, and to increase the investment in equipment, which will increase costs.

6. After-sales service: the existence of such a number of manufacturers, it may be possible to go to provide after-sales service, which covers the repair, maintenance, etc., and these services, too, will be included in the processing price.

The above is the basic concept of Chi-Kai CNC for concave-convex mould, to grasp the process of wire-cutting machining of concave-convex moulds, but also consider the factors affecting the price, so that you can better understand the process, and in the selection of processing services to make a wise choice. If you are in the surrounding areas of Suzhou, you can go to Zhikai CNC to know the new processing technology of concave-convex mould machining on the spot, which will be more intuitive.
