The difference between 3 axis and 4 axis and 5 axis is in CNC machining

The main difference between 3-axis, 4-axis, and 5-axis CNC machining is the number of directions in which the cutting tool can move relative to the workpiece.

1、3-axis CNC machining: In 3-axis CNC machining, the cutting tool can move along three directions – X, Y, and Z – that are perpendicular to each other. This allows the cutting tool to create simple geometries and shapes, such as holes, slots, and flat surfaces.

This allows the cutting tool to reach areas of the workpiece that would be difficult or impossible to access with a 3-axis machine, such as angled holes and curved surfaces. 4-axis CNC machines are often used for producing parts with more complex shapes and geometries than those produced with 3-axis machines.

3、5-axis CNC machining: In 5-axis CNC machining, the cutting tool can move along the same three directions as in 3-axis machining, and it can also rotate around two additional axes – typically the A-axis and C-axis. This allows the cutting tool to reach every surface of the workpiece and create complex shapes and features with high accuracy and precision. 5-axis CNC machines are often used for producing parts and components for industries such as aerospace, automotive, and medical, where high precision and complex geometries are required.

Overall, the main difference between 3-axis, 4-axis, and 5-axis CNC machining is the level of complexity and precision they offer. 3-axis machines are suitable for simple geometries and shapes, while 4-axis and 5-axis machines are capable of producing more complex shapes and features with high precision and accuracy. SJ has a strong supply chain support, if there is a complex parts processing needs, welcome to the drawing inquiry.

Overall, high-speed milling is a versatile and efficient machining process that is well-suited for a wide range of applications in industries such as aerospace, automotive, and medical devices.

 

What is Electrical Discharge Machining

Electrical Discharge Machining (EDM) is a non-traditional machining process that uses electrical energy to remove material from a workpiece. It is also known as spark machining, spark eroding, or die sinking, and it is commonly used to machine complex shapes and features in hard, brittle, or heat-resistant materials.

The EDM process involves the following steps:

1、A conductive workpiece and an electrode, which is typically made of graphite or copper, are submerged in a dielectric fluid.

2、An electrical potential is applied between the workpiece and the electrode, creating a series of sparks that generate intense heat.

3、The heat melts and vaporizes the material at the contact point, creating a small crater in the workpiece.

4、The electrode is slowly lowered into the workpiece, and the process is repeated until the desired shape or feature is created.

5、The dielectric fluid is constantly circulated to flush away the molten material and prevent the electrode from overheating.

EDM offers several advantages over traditional machining methods, including the ability to cut complex shapes and contours with high precision and accuracy. It is also well-suited for machining hard or brittle materials that are difficult to machine with conventional methods. However, EDM can be a relatively slow and expensive process, and the electrodes can wear out quickly, requiring frequent replacements.

Surface finish grade in CNC machining

Surface finish grade in CNC machining refers to the level of smoothness, texture, and accuracy of the surface of a machined part. The surface finish grade is often specified using a measurement system known as Ra or roughness average. Ra is the average deviation of the surface features from the mean line, measured in micrometers (μm) or microinches (μin).

In CNC machining, the surface finish grade is influenced by several factors, including the cutting speed, feed rate, tool geometry, material properties, and coolant/lubricant used during machining. The surface finish grade can have a significant impact on the functional and aesthetic qualities of the final product, such as its wear resistance, corrosion resistance, and visual appeal.

Surface finish grades typically range from rough to mirror finish, with each grade having specific Ra values. For example, a rough finish may have an Ra of 50-100 μm, while a mirror finish may have an Ra of less than 0.2 μm. The surface finish grade required for a particular application depends on factors such as the part's function, material, and aesthetic requirements.

In summary, surface finish grade in CNC machining is an important aspect of the manufacturing process that determines the quality and functionality of the machined parts. It is typically specified using a measurement system such as Ra and is influenced by various factors that need to be carefully considered during the machining process.
