The Key to Defense: Military Precision Parts

Machining Processes Military Precision Parts

The CNC machining method is subtractive, meaning it removes parts of a material to create the desired part or product. There are a few different CNC machining processes including milling using vertical or horizontal mills, and turning using conventional lathes or Swiss lathes. CNC machining is generally used for projects that would be difficult to create manually and projects that are difficult to replicate, making it ideal for creating military precision parts.  

Types of CNC Machines and How They Impact Performance

There are quite a few CNC machining processes, each of which creates different parts. CNC milling and lathing are two common processes, however, they are vastly different from one another. 

3-Axis CNC Milling

During this process, the workpiece remains stationary as the cutting tools move along the X-, Y-, and Z-axes, shaping the workpiece as they move. 3-axis CNC machining is used to cut sharp edges, perform boring and tapping operations, mill slots, and drill holes. Generally, this process is used to create parts that are simple and do not require intricate details, such as mechanical parts. 

4-Axis CNC Milling

Again, during 4-axis CNC milling, the workpiece is stationary and the tools move around it to remove material along the X-, Y-, Z-, and A-axes. This process is used to cut holes, cut along the arc, carve cut-outs on cylinders, and perform precision engraving, milling, and drilling. 

5-Axis CNC Milling

This manufacturing process is precise and relatively quick as it does not require more than 2 setups of the part. 5-axis CNC milling can hit five sides of a part simultaneously through X-, Y-, Z-axis translation and A- and C-axis rotation. Due to the high level of precision, this process is primarily used in the medical, aerospace, military, and automotive industries. 

Swiss Lathe

Lathes use rotational force to shape materials. The Swiss lathe uses a collet and guide busing to hold stock material in place as it is turned so the workpiece is less likely to vibrate during manufacturing. Swiss lathing creates thinner, more precise cuts making it ideal for machining intricate, small-diameter parts with tight tolerances. 

CNC Lathe

CNC lathes have a turret that holds 12 or more tools, including live tooling for milling operations. The tools rely on software in the CNC machine to shape parts as the machine is rotated around the material. This is significantly more accurate than manual conventional lathes and is suitable for creating products with complex designs.
