Types of 5 axis CNC used

Generally, there are two main types of 5-axis CNCs: the full 5-axis CNC machines and the 3+2 machines.

• Full 5-axis CNC machines: In a 5 axis CNC machine, the object or material being worked on is typically referred to as the workpiece. The axis numbering (1 through 5) refers to the direction and rotation of the tools or cuts used to create or carve the workpiece. In most 5-axis machines, the first three axes are the same as their 3-axis counterparts and are referred to as linear movements. The last two rotate and pivot around the first three linear axes. Using a standard 5-axis CNC machine allows for complex machining tasks to be completed without the need to change a workpiece. This also results in better accuracy, smoother surfaces, and lower production times.
• 3+2 5-axis CNC machines: Also known as position-dependent 5-axis CNC machines, the 3+2 machine works like the first three axes of an ordinary CNC machine. However, a 4th and 5th axis swing into position and work on the workpiece, machining it in a particular direction. A 3+2 5-axis CNC machine benefits a company by reducing the number of workpiece changes that staff need to be done. While the 3+2 machines are not true 5-axis machines, they are faster and less expensive than their full 5-axis counterparts. They are an excellent choice for newcomers to the CNC world or businesses that require fairly complex work but not as labor-intensive as a standard 5-axis machine.

Specification & Maintenance

• 5 Axis CNC Machine:

  Five-axis CNC machines typically have shaft working range configurations. Here are some of them:

  • 5-Axis W-1:

    The W-1 model has a whole working range of 500mm. Its working range on the W axis is 400mm.

  • 5-Axis W-2:

    It has a larger whole working range than the W-1 model. Its whole working range is 800mm, while the W axis range is 600mm.

  • 5-Axis W-3:

    For those who want even larger working ranges, the W-3 model may be a good choice. It has a whole working range of 1000mm and an W axis range of 800mm.

  Aside from its whole working range, a 5-axis CNC machine's spindle speed and power are also crucial parameters. The spindle speed for a 5-axis CNC machine usually reaches about 12,000 to 20,000 rpm. It may be even higher for some specific models. The spindle power is usually between 7.5 and 15 kw.

• Maintenance:

  To enable the 5-axis CNC machines to last longer, users can follow a maintenance routine. Typical maintenance tasks include lubricant recharges, software updates, air dusting, and inspections. For more detailed instructions, please consult the user's manual. If a specific part needs to be repaired, replaced, or serviced, the instructions may be more elaborate and precise.

• Architecture and Design Area:

  In architecture and design, 5-axis CNC machines can cut and carve materials to make staircases, wall panels, and furniture pieces, to mention a few. The machines perfectly create these architectural and design items, adding a personal touch to the space.

How to choose a 5-axis CNC used

When choosing a previously owned 5-axis CNC machine, several aspects need to be considered to ensure that the unit selected will meet the business's current and future requirements.

• Work Capacity

  The first step in selecting a 5-axis CNC machine is to determine the type of materials and shapes that the business works with and their maximum dimensions. After establishing a business's max workpiece size, it is essential to select a machine whose worktable or vice can accommodate those dimensions.

• Spindle and Tooling System

  One of the first things to check is the machine's spindle condition and its ability to rotate at maximum RPM. In addition, it is essential to ensure that the spindle can accept the tools necessary for the business application. Any required tool changes should also be functional and in working order.

• Maintenance and Service History

  Before committing to purchasing a used 5-axis CNC, it is essential to obtain the maintenance history to evaluate the machine's long-term reliability and performance. Knowing who worked on the machine can also be key in obtaining any necessary replacement parts in the future.

• Calibration and Accuracy

  It's a good idea to inquire about the machine's previous calibration. Any machine can drift out of calibration over time, affecting cutting precision. If required, determine the cost to re-calibrate and bring the machine up to the standard required, and negotiate a fair price based on its condition.

• Software Compatibility

  The CNC controller and any associated CAD/CAM software must be user-friendly and capable of handling the required 5-axis programming. Or the controller and software must be readily upgradeable. This will ensure that the machine can easily integrate with business workflow.

• Emergency Stop Buttons

  All safety features, including emergency stop buttons, need to be checked and double-checked to ensure they are functioning correctly. If they are not, employee safety could be at risk, or there could be catastrophic machine damage.

5 axis CNC used Q and A

Q1. Does a 5-axis CNC cut to the grain increases the risk of failure?

A1. Cutting along the grain can create stronger, more aesthetically pleasing parts. Moreover, if cutting to the grain increases the risk of a breakdown, then customers should prefer cutting along the grain. Owners may configure the 5-axis CNC used' s software to cut along the grain.

Q2. How does one improve the tool change time on a 5-axis CNC?

A2. Utilizing high-capacity magazines and optimizing tool selection for each operation can help reduce tool change times. Additionally, streamlining the workflow to minimize the number of required tool changes and implementing efficient tool change algorithms within the CNC machine’s software can also contribute to faster tool changing.

Q3. Do 5-axis CNC machines need leveling like 3 and 4 ones?

A3. Yes, a 5-axis CNC machine requires leveling, just like 3, 4, and other axis CNC machines. Proper leveling is essential to ensure the machine's accuracy, stability, and optimal performance, regardless of the number of axes it operates on.

Q4. What is the maximum weight a 5-axis CNC machine can handle?

A4. The maximum weight capacity of a 5-axis CNC machine can vary depending on the specific model and its design. It is best to consult the manufacturer's specifications for the particular machine in question to determine its weight capacity.
