Using MicroBlasting to cut or etch a part (a process also known as controlled erosion) is a great method to machine many precision parts, from drilling holes in ceramic substrates to cutting slots in fragile silicon and glass wafers. MicroBlasting is “shockless,”...
One of the keys to efficient MicroBlasting is using quality abrasives. In the past, we’ve discussed why you shouldn’t recycle used abrasive - this month, let’s dive into what kind of precision abrasives you should be using.Why Are Comco’s Abrasives Superior? There are...
In this quick video lesson, we break down the 5 factors that impact most deburring applications. When you’re done, you’ll know how to deburr…better! Continue reading
Are old burrs suddenly reappearing? Are burrs popping up in a new location on your part? Is a once-reliable deburring method starting to fail? Chances are, you’re missing a measurement. Manufacturing expert, LaRoux Gillespie, shares the deburring measurements often missed that lead to recurring problems and new burr formations. Continue reading
Avoid uneven results while texturing or etching parts. Learn what stepover percentage works in most applications. Incl. stepover calculator. Continue reading
Ra or Sa alone cannot predict bond strength in all applications. Epoxied surfaces, in particular, require a more comprehensive specification. To get repeatable results in pull and peel tests, incorporate a high developed surface ratio (Sdr) and require full coverage. Continue reading
Pumice is a gentle but tough cutting abrasive. It works best in applications where softer abrasives come up short and aggressive cutting abrasives are too aggressive. Learn more about this often overlooked media. Continue reading
Edited by LaRoux Gillespie, and published by McGraw-Hill Ed, Inc. This comprehensive resource provides thorough explanations of the entire range of advanced manufacturing processes and technologies as well as practical instructions and technical guidance. A great addition to your engineering or manufacturing library.
Every detail matters in MicroBlasting. Setting or adjusting nozzle angle guarantees repeatable results. Learn what goes into establishing nozzle angle. Continue reading
Looking for precision depth control? A single pass of the focused abrasive stream from a micro-precision sandblaster can uniformly remove 5 µin (0.127 microns) or less of material. Learn how to create features with varying depths and sharp walls. Continue reading
A glimpse at nozzle fixturing options and the benefits of using Comco Hi/Performance AccuFlo-style nozzles and Quicknuts. Continue reading
Not getting a consistent surface finish? Change your surface finish spec to include three measurable details. Learn what your spec may be missing, and why these three points yield repeatable returns. Continue reading
Increasing the blast pressure may produce desired results faster, or it may turn that beautiful matte finish into a cratered moon surface. Here’s what you need to know before you crank that pressure all the way up. Continue reading
Learn the ideal distances for certain applications, what influences spot size, when to hold the nozzle close, and when to hold the nozzle farther away. Continue reading
