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.
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. Learn more in this month’s post. Continue reading
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. 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 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. Continue reading
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. Continue reading
Every detail matters in MicroBlasting. Setting or adjusting nozzle angle guarantees repeatable results. Learn what goes into establishing nozzle angle. Continue reading
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. Continue reading
Pedal pumping, or pumping the footswitch, on an AccuFlo or MicroBlaster damages key blaster components. Pedal pumping also wastes abrasive and leads to results that are hard to repeat. Learn why pedal pumping starts and how to stop. Continue reading
Does your MicroBlaster or AccuFlo suffer from unstable or weak air pressure and flow? This post looks at what could be standing in the way of your blaster’s peak performance, including connecting to your air source properly, overcoming air leaks, and removing airflow restrictions. Continue reading
The AccuFlo and ProCenter Plus are easy to set-up. Watch Santa’s helpers walk through unpacking and connecting our manual MicroBlasting system from delivery to the first blast. Then, learn how to prepare for holidays, winter and other extended shutdowns. Continue reading
Divesting bridges and crowns does not have to be a 2-abrasive process. The AccuFlo, ProCenter Plus, and Hi/Performance nozzle can divest bridges and crowns with a single abrasive. See what sets this system apart. Continue reading
Ever forget to fill your abrasive tank? Run out mid-blast? Spill abrasive during a refill? When you blast long hours, abrasive refills can become a comedy of errors. AutoFill senses when your abrasive tank is low and automatically refills it so you can stay focused on your blasting. Learn more about this smart add-on in this month’s post. Continue reading
