The present disclosure relates to sanding systems, methods, and devices, in particular to systems and methods for efficiently sanding a three-dimensional component.
Computer numerical control (“CNC”) machines process a piece of material (e.g., metal, plastic, wood, ceramic, or composite) to meet specifications by following a coded programmed instruction and without a manual operator. CNC machines utilize drills, saws, etc., to machine the material to meet the desired specifications. Machined components often have rough surfaces, which can make meeting tighter flatness tolerances difficult. In this regard, improved components and systems for improving surface roughness of three-dimensional printed components may be desirable.

With reference to the following description and accompanying drawings:
The following description is of various exemplary embodiments only and is not intended to limit the scope, applicability or configuration of the present disclosure in any way. Rather, the following description is intended to provide a convenient illustration for implementing various embodiments, including the best mode. As will become apparent, various changes may be made in the function and arrangement of the elements described in these embodiments without departing from principles of the present disclosure.
For the sake of brevity, conventional techniques and components may not be described in detail herein. Furthermore, the connecting lines shown in various figures contained herein are intended to represent exemplary functional relationships and/or physical couplings between various elements. It should be noted that many alternative or additional functional relationships or physical connections may be present in exemplary systems and/or components thereof.
In various embodiments, various components for producing more detailed three-dimensional components in a more efficient manner relative to typical systems and methods is disclosed herein. For example, an adaptable belt sander is disclosed herein, which is adaptable to be mounted to a CNC machine. Additionally, the adaptable belt sander comprises a belt system configured to sand, or polish, a component for surface finishing purposes. In this regard, the adaptable belt sander comprises a belt configured to translate along a path and engage a surface of a component to be sanded. In various embodiments, the predetermined path may be a racetrack type path. However, the present disclosure is not limited in this regard. For example, the path may be circular, oval, or the like, in accordance with various embodiments. Although described herein as traveling continuously along the predetermined path, the present disclosure is not limited in this regard. For example, a belt configured to oscillate between opposite directions is within the scope of this disclosure, in accordance with various embodiments.
The adaptable belt sander comprises a housing with a removeable mounting plate. The housing is configured to house the belt of the belt system therebetween. The removeable mounting plate is removable to facilitate changing of the belt in the belt system in response to repair or in response to swapping out a different belt for various application (i.e., when a material being sanded changes).
In various embodiments, the adaptability of the adaptable belt sander disclosed herein may greatly reduce a manufacturing time and cost for ceramic components. For example, in some cases, ceramic materials, such as silicon carbide, may have a hardness greater than tools of CNC machines, such as drills, lathes, mills, or the like. Thus, ceramic materials may have to be worked with in a different manner. Upon switching between materials typically used with CNC machines, such as aluminum, brass, magnesium, stainless, steel, carbon steel, titanium or the like to a ceramic material like silicon carbide, a tool changer of the CNC machine may swap out a CNC tool (e.g., a drill, a lathe, a mill, or the like) with the belt sander disclosed herein. Thus, various materials may be worked with limited time associated with set-up in between, in accordance with various embodiments.
