CNC Vertical Machining Centers (VMCs)

When selecting a VMC, consider factors such as:

1. Machine size and table capacity; Of first importance are the machine’s workpiece capacity and the size of the machine itself. Worktable dimensions and weight capacities determine the size of the largest workpiece that the machine can handle. Some machines offer a compact design that can permit machining of larger workpieces when floor space is limited.
2. Spindle speed and power
3. Number of axes and their travel range
4. Control system and software capabilities
4. Tool magazine capacity and tool-changing speed; Factors included in choosing an automatic tool changer include its capacity in terms of number, weight and size of the tools, as well as chip-to-chip changeover times
5. Production volume; Anticipated production volumes influence selection of workpiece handling equipment. Automatic part loading and chip removal expedite long production runs, while features that minimize setup time facilitate changeovers in high-turnover short-run situations.
6. Component material; Workpiece material machining characteristics dictate machine performance requirements. For example, if most work includes finishing of softer materials, high-speed machining capability will produce the best results. On the other hand, heavy roughing of hard materials demands low-speed torque and maximum machine rigidity.
7. Advanced features like probing and automatic tool measurement
