What is MicroBlasting?
When traditional sandblasting is too harsh or overwhelming, MicroBlasting provides a precise and controllable alternative to material removal and surface alteration. Unlike sandblasting, MicroBlasting uses a very fine abrasive media mixed with compressed dry air. This mixture propels through a miniature nozzle designed to increase the stream’s velocity and allows an operator to precisely direct it at a target. It provides a quick, cost-effective and environmentally friendly solution for cleaning or altering micro parts and intricate features.
MicroBlasting is used by many industries to texture, deburr, clean and erode a wide variety of materials—even the most delicate. By simply adjusting the blast pressure, abrasive or nozzle; a Comco MicroBlaster easily adapts from a tool that cuts vias in silicon wafers into a tool that deburrs the heel of stainless steel needles.
The micro-scale of our finishing technology is ideal for refining and perfecting intricate geometries, delicate surface layers, and small parts that must meet strict industry standards. MicroBlasting is capable of processing parts as small as a grain of rice to as large as a basketball. It is precise enough to deburr the ID of a capillary tip 25 µ in diameter and efficient enough to texture selected sections of a basketball-sized part without masking.

Pedal pumping refers to the rapid pressing and releasing of a micro-abrasive blaster's footswitch. This action quickly starts and stops the abrasive stream. Pumping elicits blasting intervals that last 2-4 seconds. It looks like this: Operators tend to pump the...read more
What can MicroBlasting do?
MicroBlasting is one of the most versatile material removal methods available. Each process below is driven by four main variables: abrasive size, abrasive type, abrasive quantity, and velocity. Simply adjusting at least one of these variables turns a MicroBlaster from a tool that deburrs to a tool that cleans or a tool that textures.
Enhance the adhesion characteristics of a surface for bonding or modify the surface for cosmetic reasons.
Remove fine burrs on a wide range of materials from exotic metal alloys to soft polymers.
Four key elements comprise a Comco MicroBlasting System.
Confines the abrasive, illuminates and magnifies the work area, and provides adequate air flow for dust collection and removal.
Specifically designed to extract micron-sized particles and return clean air to the blasting chamber.
Need higher throughput?
Parts handling systems from the people who know how to automate in a harsh, abrasive environment. Each automated system is built from common components but customized for your specific application requirements.
Is MicroBlasting right for your application?
Many factors contribute to the best process: type and size of abrasive, size and shape of nozzle, air pressure, blast time and position. Our Applications Engineers have the tools on-hand to test different variables and the experience to know where to begin.
All test procedures and results are documented in a full lab report returned to you alongside the tested sample parts for evaluation.
