About VMC
VMC machining refers to machining operations that utilize vertical machining centers (VMCs), which, as the name suggests, have vertically oriented machine tools. These machines are primarily utilized to turn raw blocks of metal, such as aluminum or steel, into machined components. They can be used to perform a variety of machining operations, including, but not limited to, the following: cutting, drilling, tapping, countersinking, chamfering, carving, and engraving. This versatility, combined with their relatively low cost, has made them a highly common machine shop tool.
Advantages of VMC Machining
Compared to horizontal machining centers, vertical machining centers offer a number of advantages, such as:
- Simpler structure. The simple structure of VMCs makes it easy to clamp the workpiece in the necessary position.
- Better cooling efficiency. Gravity works with the VMC design. Coolant sprayed at the top of the machine tool and workpiece trickles down to cover the rest of the target.
- Easier setup and operation. VMCs have a wide field of vision, enabling operators to observe the operations and, if needed, make modifications to resolve any issues.
- Smaller space requirements. The vertical design takes up less floor space than a horizontal design.
- Higher accuracy. VMCs can produce complex shapes and structures with a high degree of accuracy.
Applications of VMC Machining
Vertical machining centers can be used to manufacture parts and products for a wide range of industries and applications. However, they are primarily used for high-precision, high-accuracy, and mass-production projects, including those involving the following machined components:
- Complex curved parts. Examples of parts with complex curves include cams, impellers, and propellers. While these parts are difficult to manufacture with precision and accuracy using conventional machining methods, a multi-axis VMC with CNC technology can produce them easily and quickly.
- Special or irregularly shaped parts. Examples of parts with irregular or special shapes include brackets and bases. These components often have highly complex designs, which are hard to produce using other manufacturing methods but easy to produce using VMCs with automatic machining capabilities.
- Military parts. The military industry is subjected to a variety of standards that dictate how a part can be designed and built. The accuracy and precision of VMCs ensure the machined components produced fully meet the necessary application and industry specifications.
