    MicroBlaster MB1006 Overview The Comco MicroBlaster® model MB1006 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.

    MicroBlaster MB1006 Section 1: The MicroBlaster MB1006 How the MicroBlaster Works As shown in Figure 1-2, below, when the MicroBlaster Power Switch on the front panel is initially turned “ON”, supply air enters through the energized air valve at the back of the unit.
  • Page 14 Section 1: The MicroBlaster MB1006 MicroBlaster MB1006 How the MicroBlaster MB1006 Works (cont’d) Stepping on the footswitch used to operate the MicroBlaster causes two things to happen: The hose pinch (shut-off) assembly for the selected tank opens, which allows air to flow from the nozzle. Refer to Figure 1-3, item 1.

  • Page 34 With larger nozzle openings, more abrasive can flow, and thus cutting speed is increased and efficiency will improve. Comco offers many different sizes and configurations (see Figure 3-2 and Table 3-4), from a 0.015" diameter round nozzle, to 0.012" x 0.150" rectangular. For most applications a round nozzle would be preferred due to the precise spray pattern.

  • Page 36 Section 3: Using the MicroBlaster MicroBlaster MB1006 Nozzle Distance The velocity at which the abrasive particles are expelled from the nozzle produces a well-defined stream that only flares about 7 - 10 degrees. Therefore, the distance the nozzle is held from the work surface will determine the size of the blast pattern as well as the material removal rate (or cutting action).
  • Page 37 A significant increase in abrasive flow does not always increase the speed at which parts can be processed. The micro-abrasive blasting process is optimized to work with less abrasive, using air flow and particle velocity to improve efficiency. Please contact Comco's Technical Support team for assistance in fine-tuning your abrasive blasting process. Rev. 9/12 Comco Inc.

  • Page 47 Comco recommends that these parts be replaced annually, or every 2000 hours of operation, whichever comes first. Establishing and following a regularly scheduled maintenance program for your equipment, can reduce costly downtime.

  • Page 48: Parts Subject To Normal Wear

    Section 4: Maintenance MicroBlaster MB1006 Parts Subject to Normal Wear All the parts through which the abrasive flows are subject to wear. These include the nozzles, hoses, hose connectors, and tank orifices. As a general rule, the smaller the opening the abrasives flow through, the greater the possibility of wear. Parts also subject to wear are the tank cover (threads) and modulator.
  • Page 49 MicroBlaster MB1006 Section 4: Maintenance Parts Subject to Normal Wear (cont’d) Modulator The modulator for each tank is an electro-mechanical device that is activated each time the footswitch is depressed. The stop/start action of the modulator contributes to a consistent flow of abrasive powder from the tank into the mixing chamber and out the nozzle.
  • Page 50 At weekly intervals (or as necessary), spray or wipe a dry lubricant such as graphite, molycote, or Teflon powder on the tank threads (order Comco P/N ST8062). If an aerosol dispenser is used, or the lubricant is suspended in a solvent, allow a few minutes for the solvent to dry before installing the cover.

  • Page 51: Leaks

    MicroBlaster MB1006 Section 4: Maintenance Cabinet and Cables At six-month intervals, unplug the power cord and inspect it for cracks or cuts. Also check the footswitch cable. Remove the cabinet cover and inspect the inside of the MicroBlaster for obvious leaks. Clean thoroughly with a small brush and vacuum hose (never use air or try to blow off abrasive).

    NOTE: Improper repairs may void your warranty. If you have any questions, consult with Comco before you do any work on the inside of the MicroBlaster MB1006. Most problems that can occur with your MicroBlaster will fall into either one of two categories: No air flow - Nothing happens when you depress the footswitch.

  • Page 58 Section 5: Trouble-Shooting and Repair MicroBlaster MB1006 The Handpiece Nose The handpiece nose is the main part of the handpiece that holds the nozzle. The nose holds together the abrasive hose, handpiece tube and the nozzle. Abrasive will wear away the inside of the nose to a point where it can no longer support the hose. Also, if the nozzle is not tightened firmly into the nose, abrasive leakage will wear away the threads and the nozzle will not fit properly.
  • Page 59 MicroBlaster MB1006 Section 5: Trouble-Shooting and Repair (cont’d) Abrasive Hose Replacement Procedure Feed a 6 ft. length of new hose MB1233 (or the old cut back hose) through the pinch tube. Slip the rubber grommet (ST5010) and the Quicknut onto the hose.

  • Page 60: Inspecting And Repairing The Pinch Valve

    (see replacement procedure, “Abrasive Hose”, above). Remove the pinch tube. Inspect it for sharp edges or pitting due to abrasive leakage. Replace if necessary with Comco part number MB1282. Inspect the pinch plunger for sharp edges or pitting due to abrasive leakage.
  • Page 61 MicroBlaster MB1006 Section 5: Trouble-Shooting and Repair (cont’d) Inspecting and Repairing the Pinch Valve Unscrew the pinch tube completely (Item 3). Inspect the pinch tube and pinch plunger as described above. Inspect the piston rod by pulling it out about 2". It should be clean, dry (not oily), and not “gritty”.

  • Page 62: Inspecting And Repairing The Modulator

    Section 5: Trouble-Shooting and Repair MicroBlaster MB1006 Pinch Delay Adjustment The abrasive pinch assembly is equipped with a delay valve (flow control) to prevent it from opening for 10 - 15 seconds after internal pressure is released. This allows the tank pressure to escape through the vent hose, rather than the nozzle.

  • Page 65: Clogging

    MicroBlaster MB1006 Section 5: Trouble-Shooting and Repair Clogging Moisture or particulate matter contamination in the abrasive powder can cause clogging problems in your MicroBlaster. The most likely place for clogging to occur is in the tank orifice. Provided the orifice is sized properly for the type of abrasive being used (see Section 3, “Orifice Selection”), the powder should always flow freely from the tank.
