Frequently Asked Questions

What is the rotary axis on a CNC router?
The rotary axis on the CNC router is an additional axis, usually labeled “A-axis”, that enables the rotation of the workpiece. Traditional 3-axis CNC routers operate on three axes (X, Y, and Z) to move along a linear path, while the rotary axis adds a fourth rotational dimension.
The rotary axis allows the CNC router to work on cylindrical or curved surfaces. Rather than just moving the cutting tool in a linear direction, the A-axis enables the CNC router to rotate the workpiece, allowing it to engrave or engrave on the circumference of a cylindrical object. This feature is particularly useful for tasks such as machining table legs, rotating parts, or complex designs on sculptures.
By integrating a rotary axis, the CNC router gains versatility, allowing it to handle a wider range of projects involving round or cylindrical workpieces. This feature is especially beneficial for industries such as woodworking, prototyping, and manufacturing, where the ability to work on curved surfaces is critical.
Choosing the installation location of the CNC router’s rotary axis, whether on the side of the machine or the work table, requires careful consideration of various factors. Here’s a breakdown of the considerations for both options:

The rotary axis on one side
  • Advantage:
  1. Mounting the rotary axis on the side saves bench space, allowing for larger workpieces or multiple setups simultaneously.
  2. Because the rotating axis does not obstruct the workbench, workpieces can be loaded and unloaded more easily, improving operator convenience.
  • Shortcoming:
  1. Additional floor space is required on one side of the machine.
  2. Since the rotary axis has a fixed position, the overall length of the workpiece may be limited.

The rotary axis on the work table
  • Advantage:
  1. Maximize the use of existing machine floor space.
  2. The axis of rotation can be flexibly positioned along the length of the table.
  3. Allows longer workpieces to be machined by repositioning the rotary axis.
  • Shortcoming:
  1. Material handling may be complicated, especially with heavy or bulky workpieces.
  2. Careful planning is required to avoid interference with linear axes and tools.

When choosing between these options, consider the following factors:
  • Workpiece Length: If you often handle long workpieces or workpieces of different lengths, mounting the rotary axis on the workbench allows flexibility to accommodate different sizes.
  • Space Constraints: Evaluate the available floor space of your workshop. If space is limited, mounting the rotary axis on the workbench may make more efficient use of the existing floor space.
  • Workflow Efficiency: Consider the overall workflow and how mounting location affects material handling, tool changes, and overall machining efficiency.
  • Operator Accessibility: Evaluate how each option affects operator access to the appliance, especially during setup, programming, and maintenance.
