Machining Methods in Mold Processing

Mold is an important tool for the production of parts in the manufacturing industry, and its accuracy and quality directly affect the quality of the final product. In the process of mold processing, machining is a basic and commonly used technology, which will be introduced in this paper.

1. What is machining?

Machining refers to the process of cutting, drilling, milling, grinding and other materials such as metals through mechanical equipment to achieve the specified shape and size of the processing method. It is one of the most important processing means in mold manufacturing.

2. What are the common machining methods?

(1) Turning: Turning is to cut the metal on the surface of the material by rotating the tool to form the specified size and shape. It is one of the most commonly used methods in mold processing, and is often used to make shaft and sleeve parts.

(2) Milling: Milling is a processing method that uses a rotating milling cutter to cut the surface of the workpiece. It can process complex shapes and contours, such as cavities and grooves of molds.

(3) Drilling: Drilling is the process of machining holes in the workpiece by rotating the drill bit. According to the needs, the drilling can be divided into blind holes, through holes and step holes.

(4) Grinding: Grinding is a processing method that uses a grinding stone or a grinding wheel to remove the surface of the workpiece in a small amount to achieve high-precision size and finish. It is often used in the final finishing stage of molds.

(5) Planing and cutting: Planing and cutting is a processing method to remove metal by moving the tool between the tool and the workpiece, which is suitable for processing complex shapes such as cavities and slots.

3. What are the advantages and limitations of machining?

The advantage of machining is that it can achieve high-precision and high-efficiency production, suitable for high-volume production environments. At the same time, it also has better maneuverability and low cost. However, the limitation of machining is that it cannot handle overly complex three-dimensional surfaces, and more advanced machining techniques may be required for new materials and new structures.

4. How to choose the appropriate machining method?

Choosing the right machining method requires consideration of a number of factors, including the geometry of the part, material characteristics, production volume and cost. Under normal circumstances, turning is suitable for shaft parts, milling is suitable for complex profiles and cavities, drilling is suitable for hole parts, grinding is suitable for high-precision surface treatment requirements. Each processing method has its specific application scenario, reasonable selection can improve production efficiency and reduce costs.

In short, machining plays an important role in mold manufacturing. With the progress and innovation of technology, new machining technologies and equipment continue to emerge, providing more possibilities for the mold manufacturing industry. Understanding and mastering these technologies is of great significance for improving mold quality and reducing manufacturing cost.
