Precision machining

Precision metal machining on CNC machines is our core competency.

What is precision machining?

Precision machining is the process of precision parts manufacturing using machine tools and cutting tools. The manufacturing process itself involves shaping the geometry of the part by cutting material from a block of raw material. The distinctive feature of this manufacturing method is that it maintains the high precision of the manufactured components.

Parts manufacturing by this method is based on the fundamentals of CNC machining technology, except that much more focus is placed on the quality of execution of each operation within the process. As part of the precision machining process, almost all machining operations, such as CNC turning, CNC milling, drilling, and others, are used.

To achieve the expected tight dimensional tolerances of the precision parts produced, operations such as grinding, polishing, honing, and other such operations are particularly important in this manufacturing process. These are methods of material machining designed to finish parts with a focus on the highest dimensional precision.

The process flow of precision machining

Precision machining is a complex, multi-step process that aims to achieve uncompromising quality in manufactured parts ultimately. The individual steps may vary depending on the category of machined parts. Still, a few basic process steps can be distinguished:

1. Design: the first step is to create a detailed design of the part to be machined. This design will include specifications for the size, shape, and tolerances of the part.

2. Programming: The next step is to create a program for the machine tool that will be used to create the part. This program will contain instructions for the machine on moving and machining the material to create the desired part.

3. Setup and Inspection: Before machining can begin, the machine must be equipped with the proper tools, and the material to be machined must be checked to ensure it meets specifications.

4 Machining: The machining process involves the machine following a programmed set of instructions to achieve the desired shape and dimensions of the part by cutting and shaping the material.

5 Inspection and quality control: Once the machining process is complete, the part is inspected to ensure it meets specifications and tolerances. Adjustments, if required, are implemented, and the part undergoes testing to verify that it aligns with the desired quality standards.

6. Packaging and shipping: the final step is to pack and ship the finished parts to the customer.

What materials can be used in precision CNC machining?

Due to the high flexibility of the process, the versatility of the machine tools used, and the ever-expanding capabilities of cutting tools, there is a wide range of materials for precision machining. Among the most popular are:

Machining of stainless steel
Machining of brass
Machining of alloy steels
Machining of titanium
Machining of carbon steel
Machining of special alloys

Advantages of precision machining

Precision machining is becoming increasingly important in parts manufacturing for industry. This is due to a number of undeniable advantages of this manufacturing method.

High precision and accuracy:
The process allows for the highest dimensional accuracy in manufactured parts, making it often the only possible choice for the most demanding parts.
Repeatability:
This is a key advantage in industries requiring high volumes of precision parts. Where products are assembled in series on production lines, any dimensional inconsistency is cause for downtime of the entire process.
Efficiency:
Precision machining can be a very efficient process. With modern machines and cutting tools, the highest precision parts don’t have to come at the cost of extended machining times.
Cost-effectiveness:
There are a number of factors that make precision machining an economical process. The main ones are automation and computerized control, which eliminate errors, defective parts, and the costly contribution of human labor.
Complex parts:
The process gives a wide range of possibilities for obtaining complex shapes of manufactured parts. There are some limitations while they are much smaller than other parts manufacturing technologies.
Quality:
This manufacturing technology produces high-quality parts that are durable and long-lasting. This is due to the precision of the process and also the availability of a wide range of materials for parts manufacturing.
Automation:
Thanks to the machine tools’ computerized control, this process is perfectly suited for automation, from feeding the machining material to the machining itself to collecting the part from the machining zone.
Versatility:
Unlike methods such as casting or forging, precision parts machining is suitable for manufacturing a very wide range of parts and is not subject to such strict limitations as other processes.
