CNC-turned Parts with Final Inspection
APPLICATIONS OF PRECISION MACHINING
Precision machining produces parts to a much more exacting standard than baseline CNC machining. It is an excellent solution to meet stringent project requirements, such as:
Tight tolerances. With the right equipment available, precision machining can produce parts with tolerances as small as ±0.0001″.
Repeatability. Successful precision machining means that parts must be able to be machined to the same tight tolerances repeatably from part to part.
Volume. Precision machining practices can handle virtually any production volume requirement ranging from prototypes to high-volume production runs and blanket orders.
MULTI-AXIS CNC MACHINING
The machine tools typically used for high-precision CNC machining have what is known as multi-axis capabilities. With multi-axis machining, processes can be performed simultaneously and save substantial setup time, leaving less room for human error that may occur during part repositioning.
Most standard CNC tools work on at least 3 axes, allowing work on the X, Y, and Z linear axes at the same time. Multi axis precision machining, however, typically relies on 4 to 5-axis machining for its efficiency and superior capabilities. With the addition of the A/C and B axes, 4 to 5-axis CNC machining offers greater precision and detail and can access the workpiece from virtually any direction.
Generally, 4 to 5-axis machines are the bare minimum for precision machining. Multi-axis machines are available with up to 9 axes of motion, providing the ultimate in precision machining. Multi-axis CNC machining is frequently used to manufacture medical and aerospace parts, as well as automotive parts and components for power generation.
