Rotaries are used for engraving cylindrical objects with ease. Full Spectrum Laser offers two different types of rotaries: a chuck and a friction rotary.
What is the difference?
A chuck is a mechanical device that uses jaws to grip and hold onto an object securely. It works by applying a tightening force on the object to keep it in place. For a chuck rotary, the chuck is used to hold the object in a fixed position while the laser head moves along the object to engrave it. Chucks are commonly used for engraving large objects with a larger diameter, such as tumblers and wine bottles.
On the other hand, a friction rotary uses a rubber roller to grip and rotate the object. The rubber surface provides friction against the object, which allows it to rotate as the roller turns. The advantage of a friction rotary is that it can hold objects of various diameters, as the rubber can conform to the shape of the object. Friction rotaries are more compact than chuck rotaries are generally preferred by people using delicate material, such as glass, as overtightening the chuck rotary will cause it to break.
Full Spectrum has two models of friction rotaries: a normal sized rotary and a low profile model. The low profile rotary is made to be used with all or our machines while reducing the amount of space a rotary would normally take.
In summary, the main difference between a chuck and a friction rotary for laser engravers is the way they hold and rotate the object. Chucks use mechanical jaws to grip the object, while friction rotaries use a rubber roller to provide friction and rotation. The choice between the two will depend on the size and shape of the object being engraved.
