MicroBlasting for Production Environments

When a manual MicroBlasting system cannot provide the output or meet your tolerance requirements; Comco’s automated systems deliver all the benefits of a manual system with greater precision and efficiency. Both the Advanced Lathe and the JetCenter are designed for the steady processing of precision parts. Each automated system is customizable from a proven platform and delivered as a turnkey solution.

Philosophy Behind Our Design

The abrasive environment creates a unique challenge for parts-handling. Very fine abrasive media traveling at a high velocity affects all that it touches, including your blast system’s interior. The key points behind our design philosophy:

  • Keep abrasive away from motion components and other sensitive components.
  • Use both gravity and airflow to move abrasive out of the blast chamber as quickly as possible.
  • Make wear points as durable as possible and easily replaceable.
  • Keep the abrasive focused on the part to avoid overspray and the wear and waste associated with it.

MicroBlasting uses very hard and very fine media–as hard as diamonds and as fine as moondust. Most off-the-shelf systems are designed for bigger particles at slower speeds, so these systems may not be abrasive-resistant to MicroBlasting media. We have over 50 years’ experience designing and producing rugged blasting equipment ready for these unique circumstances.

Precision and Repeatability

MicroBlasting delivers precision and control, making it ideal to process intricate geometries, delicate materials, and small parts that must meet strict industry standards.

How do we define precision and control?

  • controlled erosion to 70 nm
  • tolerances as tight as ±0.5 µ
  • delineation with a transition zone of less than 0.007”
  • a consistent surface finish to a specific Ra (5-150 µin) with a standard deviation of less than 5.0 µin

How do we achieve precision and control?

  • very fine abrasive (17.5 – 350 µ) carefully sized and free of impurities
  • small nozzles (0.018″ – 0.12″) with rugged interiors
  • angled, extended and custom-designed nozzles
  • custom blast heads and tooling
  • consistent abrasive and air feed
Both Comco automated systems deliver expected and uniform results with every pass—be it on a single part design or a family of different parts.

Simple Operation Without Compromise

Comco’s User Interface (UI) adapts a precision parts-handling system to a MicroBlasting environment. The operator interface fosters a straightforward workflow, and the engineering interface enables multiple programs to be created remotely for use across multiple machines. Capabilities of the User Interface include:

Smart Tooling

  • Coordinates the blast program with the required part tooling and blast head
  • Facilitates proper configuration before start-up through a series of clearly mapped, color-coded system checks
  • Clearly notifies and instructs operator in the event of an error

Flexibility

  • Identification protocol supports up to 15 different blast head designs and 127 different part tools
  • Text messages can be edited to suit each application and translated into a local language

Control

  • Separate interfaces for operation and engineering
  • Password-protected engineering interface that gives the engineer complete control over the system

Other Options

Never stop to refill your tank again. Comco’s AutoFill is an add-on module for a tall tank AccuFlo that will automatically refill the tank with abrasive. It monitors the amount of abrasive in a blaster’s tank. When the abrasive is low, AutoFill replenishes the tank with no operator involvement.

Comco developed the Nozzle Alignment Laser to make fixturing applications easier.

When attached to the back of any Comco nozzle, the Nozzle Alignment Laser places a dot on the surface of the targeted part where the abrasive will strike. Once alignment is set, simply remove the Nozzle Alignment Laser and attach the abrasive hose.

Peace of Mind
