Scope of Activities – CNC Machining, Quality Control and Partner Processes
As part of our offer, we carry out a wide range of CNC machining services, and we cooperate with technological partners who support us in finishing processes.
Below we present details on turning, quality control, and additional operations performed in cooperation.
CNC Turning – Precision Metal Machining
We produce components of varying complexity – from precise technical parts to less complex components used in mass production.
Precision metal machining includes carbon and stainless steel, brass, aluminum alloys, copper, and plastics.
Our modern CNC machine park and a team of experienced technologists enable us to select the optimal manufacturing technology, which translates into quality, repeatability, and competitive pricing.
All parts are inspected in our metrology laboratory, which verifies dimensional, geometric, and technical compliance based on customer documentation.
Partner Processes – Heat Treatment, Chemical Processing, and Coatings
In collaboration with trusted partners, we also offer heat treatment, chemical processing, and the application of protective and decorative coatings.
These processes are carried out in accordance with customer documentation and applicable technological standards, ensuring quality continuity at every stage of production.
Industries We Serve
We serve clients from various industrial sectors – from high-precision technologies to general mechanical applications.
We manufacture components in line with technical drawings and quality standards, adapting the process to the specific needs of each industry.
