Overview
The Comco MicroBlaster® model MB1002 is a compact bench-top machine that delivers
a precisely controlled stream of micro-abrasive particles at high velocity. With the
appropriate abrasive powder and the necessary adjustments, it will clean, deburr, cut or
drill any material, particularly hard or brittle ones. Since dry air is used as a propellant, it
is a relatively clean process.
The machine is essentially simple and uncluttered (see Figure 1-1). It consists
principally of an inlet air valve (rear panel), air pressure regulator with gage, a tank
select switch, modulators (internal), abrasive powder tanks, and mixing chambers. The
abrasive hose pinch assemblies to stop and start the abrasive flow, the footswitch to
actuate them, and handpieces that hold the precision nozzles, complete the machine.
All the component parts are manufactured to the highest standards and are designed for
maximum life consistent with reasonable cost. The basic mechanisms employed,
particularly the modulators, are covered by the following patents:
United States: ............3,053,016 Johnson
3,084,484 Hall
3,638,839 Weightman
United Kingdom: ........1,243,294
Additional United States and foreign applications for patents are pending.
