FAQ
Through the controlled movement of cutting tools, our CNC milling machines precisely sculpt and refine the workpiece to the desired dimensions and shape, eliminating any excess material in the process.The CAD file acts as an essential blueprint, enabling our CNC machines to operate with utmost precision. Guided by the toolpath, the cutting tools traverse the workpiece, selectively removing material in accordance with the specified instructions.
This meticulous approach ensures accuracy and consistency, resulting in finely crafted components that meet the exact specifications outlined in the CAD file.By utilizing CNC milling, we deliver exceptional results, transforming raw materials into intricately shaped and precisely machined components that cater to our clients' specific requirements.
CNC milling is the use of an instrument that rotates and is moved across a workpiece to take material off its surface. Milling processes can create an array of geometries, such as smooth and inclined surfaces as well as grooves, slots and slots.
CNC turning on contrary, spins the workpiece, while the cutting tool stays stationary, forming the material to what you want. It is used primarily to make cylindrical parts. It is ideal for making parts that are symmetrical, such as shafts, pins and bushings.
Moreover, two additional rotational movements enable the tool to access even more angles and surfaces of the material being worked on. This amalgamation of linear and rotational movements defines the "5-axis" nomenclature.By harnessing these extra movements, our 5-axis CNC machines have the ability to manufacture complex shapes and intricate designs that are otherwise challenging or unattainable with traditional 3-axis machines, limited to moving solely along the X, Y, and Z directions without rotation.
This advanced capability not only enhances production speed but also ensures superior precision and facilitates the realization of more sophisticated parts in our manufacturing processes.
