CNC metalworking services for clients from Szczecin

Modern CNC machines enable achieving exceptional dimensional precision at the level of a few micrometers. The accuracy of machining processes mainly depends on the type of operation performed and the technology used. CNC milling provides dimensional tolerances ranging from ±0.01 to ±0.05 mm, while CNC turning can achieve even higher precision standards.

Key factors affecting accuracy are: machine quality, condition of cutting tools, machining parameters, and properties of the material being machined. Regular calibration checks of the equipment and replacement of worn tools ensure maintaining a consistent level of precision throughout the entire production cycle. The numerical control system eliminates human errors and ensures dimensional repeatability of all manufactured parts. Temperature control in the production hall and proper clamping of workpieces further increase the achieved machining accuracy.

CNC technology is characterized by exceptional material versatility, enabling the machining of virtually all types of metals and alloys available on the market. The most commonly machined materials include structural steels, stainless steels, aluminum and its alloys, brass, bronze, and titanium. Each material requires appropriate selection of cutting parameters, tool types, and machining strategies.

Carbon and structural steels are among the easiest materials to machine, featuring good machinability and dimensional stability. Stainless steels require special tools and cooling due to their tendency to work-harden during machining. Aluminum and its alloys have high thermal conductivity, necessitating proper cooling and correctly chosen cutting speeds. Titanium, despite machining challenges related to its high hardness, is used in the most demanding industrial applications because of its exceptional strength and corrosion resistance.

The fundamental difference between CNC milling and turning lies in the method of material removal and the types of shapes produced. Milling uses a rotating multi-edge tool that moves relative to a stationary workpiece, allowing the creation of flat surfaces, grooves, pockets, and complex three-dimensional shapes. Turning, on the other hand, uses a stationary single-edge tool while the workpiece rotates, enabling the shaping of cylindrical and conical surfaces.

CNC milling is used in the production of components with complex geometry, such as machine housings, mounting plates, or injection mold parts. This process is characterized by high flexibility regarding possible shapes and the ability to machine large-sized parts. CNC turning is primarily used for manufacturing shafts, bushings, flanges, and other rotationally shaped components, providing exceptional surface quality and dimensional precision.

Wire EDM (Electrical Discharge Machining) is an advanced metalworking technology that uses the phenomenon of electrical erosion to precisely cut complex shapes. This process employs a thin metal wire as an electrode, which moves along a programmed path, removing material through controlled electrical discharges. The main advantage of this technology is the ability to machine materials of any hardness without applying mechanical forces to the workpiece.

Wire EDM is characterized by exceptional dimensional accuracy and the capability to create intricate internal shapes that are inaccessible by other machining methods. This technology is widely used in the production of injection molds, dies, punches, and components with very complex geometries. The absence of mechanical stresses introduced into the material during the electrical erosion process makes this method indispensable for manufacturing precision parts that require preserving the original material structure.

Automation of CNC machining processes brings significant benefits in production efficiency, quality of workmanship, and operational costs. Eliminating the human factor from the machining process ensures identical parameters for all produced parts, regardless of the production batch size. CNC machines can operate continuously for many hours without operator supervision, which significantly increases the productivity of the manufacturing facility.

Automatic tool change systems and dimensional control during machining allow for a significant reduction in production cycle times. Process repeatability, consistent quality of workmanship, and the ability to produce complex shapes are key advantages of automation. CAD/CAM systems enable optimal planning of tool paths and cutting parameters for each specific part, resulting in minimized tool wear and reduced material waste. Automatic process control eliminates operator errors and guarantees maintaining specified dimensional tolerances throughout the entire production cycle.

Quality control in CNC metal machining processes plays a fundamental role in ensuring that manufactured components meet technical requirements and customer specifications. Precise dimensional measurements, tolerance checks, and surface quality assessments are essential elements of every production process. The use of advanced measuring instruments, such as coordinate measuring machines or laser interferometers, enables accurate verification of all geometric parameters of the components.

Systematic quality control also includes monitoring the condition of cutting tools, machining parameters, and environmental conditions in the production hall. Statistical process control, measurement result documentation, and quality trend analysis allow for early detection of potential issues and implementation of preventive corrections. Certified quality management systems guarantee customers that manufactured components comply with the highest international standards, which is especially important in industries with stringent safety requirements, such as aerospace and medical fields.
