Precision parts

Have you ever wondered how machinists make complex metal components like engine parts? Of course, they did not make these by hand. In fact, they make these metal parts using a method called “precision machining.” Precision machine components can be obtained from various types of machines. CNC machine 3-axis, 4-axis, and 5-axis are noteworthy. We can get multi-dimensional services from these CNC machines.

After years of development and innovation, it has developed into a large enterprise integrating R & D, design, and production of CNC precision parts.

Precision machine components are the backbone for countless products and systems we rely on daily. Today, we will explore the fundamentals of precision machining and its pivotal role in manufacturing. We will also learn the real-world manufacturing steps in the precision manufacturing process. Moreover, we will discuss precision machine components, their benefits and their applications.

Definition Of Precision Machining
Precision machining is a computer-controlled material removal process from a workpiece. A CNC machine translates the user programs into the machine language to control the movement of the cutting tool and the workpiece. The machine tool then precisely cuts the workpiece using the rotation technique. Finally, it results in an exact finished product.

Precision machining is characterized by its high-velocity operations, ensuring efficient material removal. In addition, the process maintains tight tolerances. It also guarantees precision down to the minutest detail, like ±0.001mm. Moreover, the method is famous for its ability to create complex, designed parts. This ability makes the process suitable for various manufacturing processes.

Steps In The Precision Machining Process
The precision machining process is well-organized and transforms workpieces into intricately designed components. The systematic approach to precision machining also ensures professional output. The following are five primary steps of the process.

Step 1: Designing the graphical model using 3D
Firstly, the process begins with the creation of a 3D model. In this case, this digital blueprint acts as the foundation for the rest of the operations. For example, SolidWorks, AutoCAD, Siemens NX, and CATIA are some popular software.

Step 2: Conversion of 3D to CAM
The process then translates the 3D model into machine-readable instruction using CAM software. CAM stands for Computer Aided Manufacturing.

Step 3: Machine setup and calibration
This step includes securing the workpiece and loading the required tools for machining. And then, what we should do is precisely calibrate the CNC machine for accurate machining. In this case, this calibration process involves setting the correct position of the workpiece and the tools.

Step 4: Execution of machining
With the machine prepared, the CNC system executes the programmed instructions. The program may vary for cutting, milling, drilling or shaping.

Step 5: Completion and potential secondary processes

Finally, the component goes through several inspection processes for quality and accuracy. Depending on the application, additional processes may be necessary to meet specific requirements.

Different Precision Machining Methods And Equipment
We can get precision machine components from various methods and equipment. Each method is subjected to meet specific manufacturing needs. In addition, it helps us to achieve unique accuracy.

CNC milling machines employ rotary cutters to remove material from a workpiece. These machines are ideal for creating 3D shapes.
CNC turning machine is prevalent for precision turning operations. The whole workpiece rotates in these machines, and a cutting tool shapes it.
Precision grinders are popular for achieving precise surface finishes and tight tolerances. These machines are applicable on flat or cylindrical surfaces.
CNC drills create holes and bores in the workpiece.

Multi-axis CNC machines can move the workpiece and the cutting tool in multiple directions. As a result, they can produce complex CNC machining components.
EDM stands for Electrical discharge machine. It uses electrical discharges to cut material. This method is famous for making complex moulds and dies.
Swiss machining usually is a CNC lathe. These machines are famous for manufacturing small CNC machining components.

CNC laser machines use laser beams to remove materials. They work on various materials, like wood, metal, plastic, or paper.
Mill-turning CNC centres combine CNC milling and turning operations. These machines are also suitable for producing complex components.

Learn inspection

This technological process includes:

1: After the workpiece is put on the machine, the work should be re-checked according to the drawing and process. Only when the inspection is within the tolerance range can be processed according to the requirements of the program sheet, so that the drawings, processes, and the program sheet are all corresponding.

2: In terms of size, the touch of the workpiece, and the size of the insertion position meet the requirements of the 3D drawing file. For the position of EDM, CNC needs to leave the EDM margin, and the more important assembly positions should be measured by 3D inspection.

3: For some extremely irregular CNC surfaces or positions with high size requirements, some positions that cannot be measured by common measuring tools, three-dimensional measurement is required if necessary.

4: the workpiece must not have rust, bumps, chipping, and burrs. At the same time, there should not be a large amount of residual cutting fluid, cutting oil, and iron filings in the holes on the surface of the workpiece.

5: According to the 3D drawing file, check whether the workpiece has been completely processed without omission, the benchmark is correct. All the positions requiring sharp corners (especially the sealing position) cannot be chamfered or R.And check the size according to the drawing and then check the self-check. stated on the slip.

6: The CNC machined electrode requires no burrs on the surface, the serial number and electrode number are complete, clear, and correct, and there must be no writing other than the electrode number and electrode number.
