In precision sheet metal fabrication, grinding is performed to yield a very fine finish of accurate dimensions. In essence, grinding is a cutting process utilizing abrasives as the cutting tool. Typical grinding tools include: files, handheld power tools, such as angle grinders and die grinders, as well as fixed belt and bench grinders.Closely related to grinding is sanding, a process performed to either smooth the surface or to prepare the surface for a finishing process.
Both sanding and grinding demand a high level of skill to produce accurate dimensions and finish and like deburring, are given careful consideration to deliver the best value and lowest costs to our customers.
Burrs are generally unwanted material remaining after a machining operation such as punching, grinding, drilling, milling, or turning and are usually in the form of a raised portion on the surface of the component.
When these burrs are removed it is called deburring. The cost impact of deburring should not be underestimated if it is essential to the design.
Effective deburring begins with the correct selection of die clearances used in the perforation process to minimize the formation of burrs. To provide the best value, Humble utilizes automated processes wherever possible including surface deburring with our specialized Amada finishers or tumble deburring with our barrel tumbler.
