Understanding CNC Machining

CNC machining stands for Computer Numerical Control machining, a method where computer-controlled machine tools precisely remove material from a workpiece. This computerized control results in faster, more precise, and accurate machining compared to conventional methods.

At Baranar Rapid, we utilize advanced equipment to provide a wide range of CNC machining services, including milling, turning, EDM, wire EDM, surface grinding, and more. Our imported 3, 4, and 5-axis CNC machining centers, operated by skilled machinists, can produce turned and milled parts using various plastic and metal materials. Additionally, our robust supply chain allows us to scale according to project requirements.



Tolerances

Our CNC machining tolerances adhere to DIN-2768-1-fine for metals and DIN-2768-1-medium for plastics. Tolerance levels may vary depending on part geometry and material type. Our project managers work closely with clients to ensure the highest precision possible for each project.

We also provide low-cost manufacturing of high-quality plastic parts. Our vacuum casting services offer short-cycle solutions for creating high-quality prototypes and low-volume production parts. Vacuum casting, or urethane casting, is a method that utilizes a silicone mold and a 3D printed master to produce vacuum-cast parts with consistent performance and production-grade quality. This technology does not require a costly initial investment, enables flexible and economical production, and hardens thermoplastic polyurethane in silicone or epoxy molds. The outcome is a vacuum-cast part that retains the shape of the original master model. The final dimensions of a vacuum-cast part are determined by the master model, the part's geometry, and the selected material.

Our sheet metal fabrication factory offers top-tier custom services, leveraging extensive capabilities in sheet metal stamping, cutting, bending, welding, precision CNC machining, and assembly to deliver superior quality parts. NOBLE's manufacturers employ cutting-edge technology and skilled engineers to guarantee sheet metal parts of unmatched quality, precision, and reliable performance.
