Avoid uneven results while texturing or etching parts. Learn what stepover percentage works in most applications. Incl. stepover calculator.
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.
Pumice is 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 abrasive.
Comco contributed a chapter on MicroBlasting to Design for Advanced Manufacturing: Technologies and Processes, edited by LaRoux Gillespie (McGraw-Hill Ed) Inc: practical instructions, technical guidance. A great resource for your engineering or manufacturing library.
This comprehensive resource provides thorough explanations of the entire range of advanced manufacturing processes and technologies as well as practical instructions and technical guidance.
Every detail matters in MicroBlasting. Setting or adjusting nozzle angle guarantees repeatable results. Learn what goes into establishing nozzle angle.
Looking for precision depth control? A single pass of the focused abrasive stream from a Comco micro-abrasive blaster can uniformly remove 5 µin (0.127 microns) or less of material depending on the substrate, abrasive, and blast parameters. Learn what variables to consider and adjust to create precise features with varying depths and sharp walls.
A glimpse at nozzle fixturing options and the benefits of using Comco Hi/Performance AccuFlo-style nozzles and Quicknuts.
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.
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.
Learn what goes into a creating spot size, the ideal distances for certain applications, when to hold the nozzle close, and what applications benefit from holding the nozzle farther away.
