Select robot spindle for grinding bavia

Select robot spindle for grinding bavia. The nature of burr grinding is repetitive, dirty, and carries a risk of injury. Retaining employees for such arduous and messy work is a challenge. Robotic deburring is an attractive option for these reasons and the results are more accurate and reproducible.

Factory automation

Robotic integrators are seeing a growing need for robotic debugging systems and for good reason. Deburring is necessary for various manufacturing operations, but it is difficult to attract and retain employees to do the job. Labor shortages continue, and the National Association of Manufacturers has reported that by 2022. There are 800,000 unfilled manufacturing jobs in the United States, with 2.1 million expected. in 2030. The nature of sanding work is very repetitive, dirty, and carries a risk of injury. It is difficult to retain employees for such arduous, messy, and uninteresting work. Robotic deburring is an attractive option for these reasons and the results are more accurate and reproducible.

Choosing the right spindle for burr grinding applications involves several considerations other than the milling assignment. In this article, we look at different aspects of spindle selection for bavia grinding. We also looked at polishing and sanding, which again have slightly different requirements.

From where is compliance pressure controlled?

Kenny Wilson, technical director of precision drive systems with more than 25 years of experience. Points out that the first thing to determine is whether the pressure applied to the part will be controlled by the robotic arm or itself.

A wide range of active force-compliant rotary shafts are available, which are closed-loop systems capable of maintaining constant pressure regardless of orientation. In other words, the shaft will compensate for gravity to maintain the same pressure in all positions. Less expensive passive systems may be appropriate in applications where gravity is not a factor.

If the spindle does not control the pressure then the robot arm should be.

Either way, knowing this is the first step in choosing your pin.

Insert the part into the spindle – or the pivot into the part

Wilson says he’s seen more and more cases where a robot’s baving would be accomplished by holding the spindle in a fixed position and letting the robot arm feed the part in. Spindle. The advantages of this method are manifold.

With a fixed spindle, the baviar design or designee can choose a large and powerful spindle without having to worry about the robot arm being strong enough to carry the spindle. Since the robot only needs to feed a relatively light workpiece into the spindle, the arm does not need to be as strong as it would be when it has to handle a heavy spindle. The result is a less expensive system and potentially a reduced maintenance solution.

However, some part geometries are not suitable for grinding the burr with a fixed spindle. If the robot arm carries a pivot, it is important to choose a strong enough pivot. The extra weight of the spindle will require larger and stronger robotic arms, which will increase the cost of the system. 

What are the speed and torque requirements?

Wilson described many speed and torque considerations when choosing a spindle for burr grinding, polishing, and sanding.

“For a burr grinding application, you need a spindle that can handle both radial and axial loads,” says Wilson. Usually, a standard set of bearings in the spindle is sufficient, unlike in a milling application where three or four sets of bearings may be required. “For grinding David, it is more important to spindle speed and torque than to bearing,” explains Wilson. He goes on to say that the spindle for the Bravia grinding task will likely require higher speed and torque than the milling application. While a milling application will require a lot of torque at relatively low speeds, a milling application will require more torque at higher speeds.

Sanding, having, and polishing all have their own requirements when it comes to spindle physics. Deburring usually has a high speed while hitting the ball uses a slightly lower speed. Polishing generally requires more torque at lower speeds than polishing. In a sanding application, Wilson says the angle at which the sanding wheel will contact the workpiece—and the percentage of the wheel that will make contact—must be known. The combination of these factors with the applied force allows us to calculate the torque requirements of the spindle.


The selection of the spindle for the Bravia grinding application should be done carefully in order to obtain a system that is both cost-effective and delivers the desired results. Calculating spindle speed and torque requirements requires knowledge of many different aspects of the application.
