The Importance of Chemistry in Vibratory or Tumbling Finishing and Cleaning

2022-10-13T17:25:57+00:00August 26th, 2022|Cleaning, Finishing|

The vibratory or tumbling method is cost-effective, consumes low energy and allows simultaneous and reproducible finishing of a large quantity of machined parts or tools. In this batch-type operation, the workpieces are placed with random or preformed media into a vibratory tub or tumbler. In the case of the vibratory finisher, a predetermined mixture of water and chemistry (often referred to as “soap”) is added during operation. The type of media selected will determine the type of finish–from very abrasive to “burnishing”, or polishing—that is achieved. The [...]

Dye Penetrant Inspection works well for a variety of product forms including castings, forgings and weldments. The structural steel, automotive, petrochemical, power generation and aerospace industries are a few examples of those that utilize liquid penetrant inspection. Wet Blasting has become indispensable in MRO, with distinct advantages for DPI and other non-destructive inspection techniques. Surface Cleaning and Prep  Remove coatings and strip metal parts or composites clean and ready to accept Dye Penetrants and Developers. Dirt, paint, oil, grease or any loose scale could potentially keep penetrant [...]

Improving Your Deburring Process for a Better Surface Finish

2021-01-03T23:23:10+00:00November 13th, 2020|Finishing|

Common deburring processes include vibratory finishing, electropolishing, abrasive blasting, brush deburring, chamfer and radius cutters, and that old standby, hand deburring with files, abrasive pads, and scraper knives. The problem with many of these, as Gillespie has said, is that they can affect more than the burr.¹ “When determining which one is most effective, shops must assess a variety of factors, including the burr height and thickness, workpiece material, allowable edge radius, maximum stock loss in the surrounding area, required surface finish, and, of course, the number [...]

Remove the Burrs. Improve the Product.

2020-09-30T18:37:39+00:00July 30th, 2020|Finishing|

via: larouxgillespie.com Nearly every machining process leaves some sort of burr that must be removed. But few agree on the definition of a burr, let alone a standard for describing them. A burr to one engineer is simply a sharp edge to another The Problem With Burrs. Burrs can cause issues in downstream machining processes by preventing proper location of the part in a fixture, or interfering with a metrology device. Burrs that are not detectable visually or by feel may be easy to overlook. [...]

Custom Engineered Wet Blast Systems for Emerging Applications

2020-09-23T13:10:32+00:00May 30th, 2020|Cleaning, Finishing|

The Fourth Industrial Revolution, whether you call it Industry 4.0, or Manufacturing 4.0, is opening doors to higher productivity, smarter workflows, and safer work environments. As we integrate advanced robotics, artificial intelligence (AI), IoT, additive manufacturing (3D printing), and smart energy, why not reinvent the ways in which we approach surface finishing? Wet blast systems have proven to outperform conventional manual, chemical and dry blasting processes, with the ability to combine steps, speed production and eliminate airborne dust and hazardous chemicals. And, [...]
