Micro-Lessons in MicroBlasting
Welcome to our blog where we tackle everything from basic system maintenance to specific applications to the latest in tools and technology and the science behind the process.
The Grip Wrist is the latest blast head designed for automated MicroBlasting systems. Unlike prior blast heads, it moves the part to the nozzle. See it in action and learn more.
Need to blast with a new media? Learn how to clean & prepare your blaster for an abrasive change. Includes a video walk-through and step-by-step guide.
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.
Make any 1 of these 5 common operator mistakes, and you may break your blaster–meaning unplanned downtime for maintenance or a costly factory repair. Read this post and learn how to avoid a blaster disaster.
Abrasive contamination is easily preventable. Learn how to maintain air pressure inside your blaster and make sure abrasive moves in one direction.
An easily-forgotten component, the tank orifice has a critical impact on the efficiency and consistency of your micro-abrasive blaster. Learn why and how to change the tank orifice in your Comco blaster.
The modulator is the heart of your system; the engine running the machine; the thing that turns your blaster from a simple dirt-chucker to a sophisticated surface-refinement tool. Learn more about this essential component to any Comco blaster, how to spot modulator wear, and how to replace it.
Learn how automated micro-precision sandblasting can etch channels to a precise and repeatable depth in the surface of an air bearing or hydrodynamic seal.
Deburring black PEEK is risky. This carbon or graphite-filled material easily discolors or roughens, even when using mild abrasives. Wheat starch removes burrs without changing the dimensional or aesthetic integrity of black PEEK. See the results in this post.
Wheat starch is a very soft abrasive, but it has just enough abrading power to gently lift really thin layers of conformal coating without risk to an underlying solder mask or circuit board. Learn why you may want to consider it, and learn why MicroBlasting, in general, is a great method for conformal coating removal.
