The Machine That Started It All
The MicroBlaster® has come a long way from its debut in 1968, but it is still the reliable micro-abrasive blaster our customers can expect to keep running year after year. It is tough enough to perform in high-volume production environments but versatile and affordable enough for shops or hobbyists just blasting a few days a week.
Our newest MicroBlaster is the AccuFlo. It is our most powerful, precise and efficient blaster in our evolving MicroBlaster line. It is such an engineering breakthrough that we had to give it a new name and its own page.
Simple but Effective
Our MicroBlaster was designed around a novel mechanism for mixing air and abrasive. Rather than using an inaccurate venturi or trying to shake a whole tank of abrasive, our Engineers created a system that pulses air inside the tank. The modulator is a precision electro-mechanical valve that opens and closes 60 times per second.
When the modulator opens, pressure builds in the mixing chamber. This high pressure forces air through the orifice and into the tank, fluidizing a small amount of abrasive.
When the modulator closes, pressure drops in the mixing chamber. High air pressure at the top of the tank pushes the fluidized abrasive into the mixing chamber and out toward the nozzle. Each pulse carries a small, but accurately metered amount of abrasive. The distance between the mixing chamber and the nozzle allows time and space for the abrasive and air to mix uniformly.
Why Wash a Teacup with a Fire Hose?
Working with small, delicate parts requires small tools and great control. Unlike large cabinet blasters, our MicroBlasters are designed for precision work on parts as small as a grain of rice to as large as a basketball. How?
- Modulator creates a uniform abrasive stream
- Pinch-valve provides crisp on/off control
- Lightweight handpiece improves operator dexterity
- Hi/Performance nozzles focus the abrasive stream to pinpoint accuracy
Combined, these features enable our MicroBlaster to help you target specific areas, improve yield and save the time usually spent masking.
A MicroBlaster Ideal for Multi-Tasking
Comco introduced the Dual Tank MicroBlaster® Model MB1002 for applications that require a two-step process. An operator can alternate between two different abrasives with the quick flip of a switch. The system runs on a common air supply, but each isolated tank has its own modulator and handpiece to prevent abrasive cross-contamination.
50 Years of Comco Engineering Innovation
From the time that we first released the MicroBlaster, Comco has delivered unequaled performance, reliability, and precision. Our commitment to design excellence and customer satisfaction are evident in the advancements made to each new generation of MicroBlaster.
- Our MicroBlaster now comes standard with a flow path that is lined with stainless steel and carbide to reduce wear.
- Our tank plumbing improvements ensure a more consistent abrasive stream at blast activation.
It Just Works
When Tom Deméré Ph.D., first arrived at the San Diego Natural History Museum in the fall of 1978, the Department of Paleontology had in use this Comco MB100 MicroBlaster. That blaster, originally built in 1970 continues to serve them. Tom remarked:
At forty-two years and counting, the MB100 MicroBlaster is a testament to Comco’s product longevity. During that time Comco’s Engineers have been continuously improving upon the original MicroBlaster. The AccuFlo is a machine they’ll be counting on for the next forty, and then some.
