Following the rules and regulations of each process related to cutting metal can effectively avoid quality problems.
FREMONT, CA: When using a CNC machine tool to make components, there are usually two scenarios. There is a component pattern and a blank in the first situation, and the CNC machine tool that is appropriate for the part should be chosen. The second case is that a CNC machine tool already exists, and suitable features for the machine tool must be selected. The key factors to consider in either case are the semi-finished product's material and component contour complexity, scale, accuracy, number of parts, heat treatment specifications, and many more.
The manufacturing process of hardware workpiece cutting technology
As people's demands for metal products become more diverse, new metal cutting technology requirements started emerging. While manufacturing hardware workpieces, it's essential to choose and develop technologically advanced, cost-effective, safe, and dependable process plans based on the factory's equipment and staff's actual conditions so that the workpieces fulfill the technical specifications described in the design drawings.
The following is a summary of the cutting method for hardware workpieces:
Analyze the drawing of the workpiece:
Analyze the shape characteristics, scale, precision requirements, raw material size specifications, and mechanical properties of the workpiece based on the hardware drawings. Evaluate the cutting process of the parts by using the appropriate cutting equipment requirements and production batch factors.
Select cutting blanks:
The consistency of the finished product is directly determined by the raw material properties of hardware workpieces. As a result, the blank should undergo stringent performance tests before being manufactured, such as strength, yield point, tensile strength, elongation, area reduction, hardness, impact toughness, and so on.
Selection of precision cutting oil:
Cutting oil is an essential part of the metal-cutting process. Workpiece accuracy has improved dramatically as a result of enhanced cooling efficiency and intense pressure wear resistance. While selecting a cutting oil, the focus of the results is different based on the material of the workpiece.
The rough cutting process of the workpiece:
Rough machining is the process of removing the majority of the machining allowance from the workpiece blank in order to get the shape and size as close to the specifications of the finished product as possible. It has a low processing accuracy and a high surface roughness rating. It's usually used for finishing low-demand or non-matching surfaces and even pre-processing steps before finishing.
The precision cutting process of the workpiece:
The finishing process involves removing less machining allowance from the rough-machined surface and improving the workpiece's machining precision and surface quality. Finishing is frequently used as final processing where the workpiece's surface does not have high specifications.
The finishing process of the workpiece:
It removes a small machining allowance from the finished workpiece's surface, resulting in high machining accuracy and low surface roughness. The finishing process includes methods such as grinding, honing, superfinishing, and polishing.
