Micro Machining CNC

This article takes a closer look at micro machining CNC fabrication methods for making extremely small parts, outlining some of the latest technologies used for making micro components and assemblies.

What is micromachining CNC?

Micromachining CNC (computer numerical control) equipment utilizes specialized mill and lathe machining technologies capable of multiple axes of motion to create extremely small and precise components. This process produces miniature components for various manufacturing sectors, including medical devices, and aerospace. Micro machining by CNC has made significant progress in recent years, as a result of increased demand for miniature components and devices. The following spotlights just some of these new technologies and how they are paving the way for new innovation.

5-Axis Micromachining CNC

Traditional machining typically involves 3-axis of motion: the cutting tool moves in the X, Y, and Z axes removing material to form the workpiece. 5-axis machining adds two more rotary axes, thus letting the cutting tool approach the workpiece from a variety of angles. The additional axes include: angle tilting along the X-axis, and angle tilting along Y-axis.

7-Axis Micromachining CNC

There is no limit to how many axes a CNC equipment can have. 7-axis micromachining typically the following 2 additional axes: rotation of the machining spindle, and rotation of the workpiece itself. 7-axis equipment allows for even more complex geometries machined from a single setup. Moreover, control over all of these axes makes it possible to machine highly precise geometries in extremely small parts.

Micromachining Centers

Micro machining centers automate the process of micro fabrication from end to end, performing a variety of cutting, drilling, milling, and material removal operations on a part. Additionally, machining centers can come in a variety of configurations that serve the unique manufacturing capabilities for a given design.

Machining centers typically provide end to end automation, which include:

  • Workpiece Setup: How the material is fixed to the machining equipment.
  • Tool Selection: The cutting tool is loaded based on design requirements.
  • Machining: Tool path programing is generated based on design requirements, including the path of the cutting tool, rotational speed, feed rate, and other parameters.
  • Quality Control: During machining, the system monitors the quality requirements such as dimensional accuracy, tolerances, and surface finish. Any deviations or defects are corrected instantaneously.
  • Workpiece Removal: Once completed, parts are removed for subsequent operations and inspection.
