Setting the Pressure

Blast pressure determines the velocity of the abrasive exiting the nozzle. Set it too low and it may make blasting unnecessarily slow or completely ineffective. Set it too high, and you risk damaging the part. Depending on the type of application, you might blast from...

Removing a Ductile Layer from a Brittle Substrate

Removing a Ductile Layer from a Brittle Substrate

The selective cleaning process uses the abrasive qualities of MicroBlasting to carefully erode layers of unwanted material from a base substrate. The process takes advantage of the different physical properties of the two layers. Brittle materials can be removed from...

5 Important Variables for Abrasive Jet Machining

5 Important Variables for Abrasive Jet Machining

Using MicroBlasting to cut or etch a part (a process also known as controlled erosion) is a great method to machine many precision parts, from drilling holes in ceramic substrates to cutting slots in fragile silicon and glass wafers.  MicroBlasting is “shockless,”...

The MicroBlasting Guide to Precision Abrasives

The MicroBlasting Guide to Precision Abrasives

One of the keys to efficient MicroBlasting is using quality abrasives. In the past, we’ve discussed why you shouldn’t recycle used abrasive - this month, let’s dive into what kind of precision abrasives you should be using.Why Are Comco’s Abrasives Superior? There are...

How to Tell if Your Nozzle is Worn

How to Tell if Your Nozzle is Worn

Have you noticed a change in your MicroBlasting results? As your nozzle wears, it gradually loses the tight focus. Some applications you can keep using a nozzle until it blows out the side. For others, a few thousandths wear will cause part failure. Abrasives, like...

Keeping Your Air Supply Dry

Keeping Your Air Supply Dry

If you've ever been frustrated by a full, but non functioning salt shaker, discovered a suspect mass of whey in a tub of protein powder, or had to break up a chunk of powdered detergent, you know that fine powders and moisture are not a great combination. The...

VIDEO: Using the Abrasive Blend Knob

VIDEO: Using the Abrasive Blend Knob

What is the abrasive blend knob? The abrasive blend knob can be a bit of a mystery. What's the right setting? How far can I turn it clockwise? Will opening it create a richer abrasive stream? Every blaster is configured to a specification. This means the tank orifice,...

Deburring and Texturing Bone Screws

Deburring and Texturing Bone Screws

The job: Manufacture titanium bone screws with tight tolerances. The challenges: Titanium is an excellent material for bone screws, but it hardens as it heats up, making it tough to machine, leaving fine feather burrs.  These burrs must be removed without damaging or...

Decapping ICs

Decapping ICs

Delicate silicon dies are encapsulated in epoxy to protect them. This becomes a problem when extracting the silicon die for failure analysis or reverse engineering. When using MicroBlasting, decapping an integrated circuit is safer, easier and more environmentally...
