Our team of experienced engineers can assist you in creating digital designs for CNC machining, ensuring your vision is accurately translated into a manufacturable part.

2. Programação: Once the digital design is complete, it is translated into a set of instructions that the Máquina CNC can understand. This is done using computer-aided manufacturing (CAM) software. The CAM software generates the toolpaths and cutting parameters that the máquina will follow. Computer programming is a critical skill for our machinists, as it directly impacts the quality of the final product.

3. Configuração da máquina: Before the processo de maquinagem can begin, the Máquina CNC must be set up. This involves loading the workpiece, installing the ferramenta de cortes, and calibrating the máquina. Setting up the machine correctly is crucial for ensuring accuracy and preventing errors.

4. Execução: Once the máquina é configurado, o Processo de maquinagem CNC can begin. The Máquina CNC follows the instructions generated by the CAM software, precisely cutting and shaping the workpiece. The processo de maquinagem is monitored by our skilled machinists to ensure everything runs smoothly.
