How does CNC milling differ from conventional milling?
CNC milling is performed using a digital program that defines the tool path with high precision. Unlike manual milling, CNC ensures perfect repeatability of parts in a series, eliminates operator error, and allows processing of complex 3D contours that are impossible with manual control.
What operations are performed on your milling equipment?
We have a fleet of 7 milling machines, including a modern LITZ CV-1200A with four‑axis capability. We perform flat and contour milling, slot and pocket milling, drilling and countersinking, thread milling, coordinate boring, engraving. We machine parts from steel, stainless steel, aluminum, and non‑ferrous metals.
What products is CNC milling used for?
CNC milling is ordered for manufacturing instrument enclosures, covers and panels with holes, brackets, parts with mating surfaces, flanges, base plates. The technology is indispensable where high accuracy of mutual positioning of surfaces and holes is required.
What is the accuracy of CNC milling on your equipment?
Positioning accuracy of the machines is ±0.02 mm, part dimensional accuracy is ±0.05–0.1 mm depending on material and configuration. For critical mating surfaces, we use finishing passes with minimal stock removal to achieve the required tolerance grade.
How do I prepare technical specifications for CNC milling?
The best option is to provide a 3D model of the part in STEP format (or from SolidWorks) and a drawing with tolerances, surface finishes, and technical requirements. If you only have a sketch – our design engineers will perform 3D modeling. From the finished model, we develop a control program and approve it with you before production.
Can you mill a part after welding or bending?
Yes – and this is common practice when manufacturing complex enclosures and structures. After welding, the part may have deviations from flatness or require precise mating surfaces. Milling allows restoring geometric accuracy. At our facility, all operations (cutting → bending → welding → milling → painting) are performed in‑house.
How much does CNC milling of metal cost?
The cost depends on material, geometry complexity, machining time, and batch size. In serial production, the unit cost decreases because programming costs are spread over the entire batch. To get a cost estimate, send a 3D model or drawing to ik37@bk.ru.
