What Is 5-Axis & 7-Axis CNC Machining?

Aerospace CNC (computer numerical control) machining involves manufacturing products [KH1] with the help of programmed computer software. All plant equipment and tools are automated via instructions laid out in a CAD file, which allows impeccable precision and reliability

Using a precision mini 5-axis CNC machining center [KH2] has numerous benefits, such as:

• • Cost-efficiency
  • Improved speed

• Enhanced accuracy
• Increased productivity, and more.

Aerospace CNC machining involves removing material precisely to get the desired shape – which is accurate down to the last atom. This is done across three, four, five, or seven axes, which ultimately determines the type of work needed.

Let us learn what 5-axis and 7-axis CBC machining are and what can be accomplished by the same.

What Is 5-Axis Aerospace CNC Machining?

A machine that can operate along the:

1. X-axis (vertical)
2. Y-axis (horizontal)
3. Z-axis (depth)
4. A-axis (rotation at the X-axis)
5. B axis (rotation at the Y-axis)

This requires a 5-axis Swiss lathe and offers good repeatability and precision of the aerospace manufactured [KH3] parts.

A 5-axis Swiss lathe is slightly more expensive to purchase and maintain than manual machines, but the result is much more accurate and reliable. When used for large-scale manufacturing, the economies of scale achieved are much more vivid and impactful.

5-axis CNC Machining can help you create;

• Frames
• Aerospace equipment
• Engines
• Gears
• Precision tools
• Cylindrical parts
  • External molding
  • Internal molding

• Thread cutting
• Boring
• Facing
• Grooving
• Filters
• Machine parts and more.

What Is 7-Axis CNC Machining?

7 axis machining is a complete setup on its own and can manufacture complex parts without having to transfer them to another machine. When the part drops off, it is most often complete. The 7-axis include:

1. X-axis (vertical rotation)
2. Y-axis (horizontal rotation)
3. Z-axis (moving the arm up/down)
4. A-axis (rotating at X-axis)
5. B axis (rotating at Y-axis)
6. C axis (rotating at Z-axis)
7. E axis (twisting the arm)

This type of high-precision machining [KH4] has several benefits to boast, including high efficiency, the ability to efficiently manufacture even the most complex aerospace or military equipment parts, and no need for post-fabrication. Since the 7-axis manufacturing lets you mill around the part and turn it within its frame, the function becomes much smoother and quicker.

It is even more expensive than 5-axis machining.
