Six production processes of acrylic PMMA display stand!

Acrylic display stands, as a relatively high-quality plexiglass, have been widely used in the production of various crafts and display stands. Among them, there are about six types of acrylic display rack manufacturing processes: 1. Mosaic method: According to the design drawing, use a laser cutting machine to cut the different colors of the acrylic…

What are the classification of electroplating process?

Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. According to the composition of the coating, the electroplating process can be divided into five categories: chrome plating, copper plating, cadmium plating, tin plating, and zinc plating. 1. Chrome plating…

Properties and application of PA material after adding fiber

In recent years, PP fiber reinforced materials have developed rapidly in the modified plastics industry, and most of the glass fiber reinforced materials used in the automotive field are PP substrates. With the improvement of plastic modification technology and the needs of the development of the automotive industry, the development trend of long glass fiber…

What software are commonly used in CNC programming?

The CNC machining center can process various complex workpieces by executing the processing program. There are two sources for processing programs: manual programming and programming software. For simple processing tasks, such as milling straight grooves, steps, drilling, etc., it can be completed by manual programming, which is simple, direct and efficient; but for complex three-dimensional…

What is the difference between 3-axis, 4-axis and 5-axis in CNC machining?

  What is the difference between 3-axis, 4-axis, and 5-axis in CNC machining? What are their advantages? Which products are they suitable for processing? Three-axis CNC machining: generally refers to three axes that move linearly in different directions, such as up and down, front and back, left and right. Three axes can only process one…

Advantages of CNC spark machine (EDM) electrical discharge machines edm

CNC spark machine (EDM) is a computer digitally controlled spark machine to realize multi-axis linkage processing equipment. The CNC spark machine (EDM) realizes automatic control through the computer to complete complex and precise spark machining. In the actual machining process, the computer sends instructions to control the EDM according to the input program to realize…
