As previously discussed in our Automation Blog Series, building a robotically assisted process requires evaluating your surface finishing system along with its problems and goals and selecting the right machine and consumables. Automating a mass finishing or shot blasting process also requires selecting the automated hardware that will best achieve your overall goals and provides the most efficiency in terms of time and manual labor.
An experienced partner such as Rosler Metal Finishing can provide insight and advice on the numerous material handling tools specially designed or adapted to mass finishing and shot blasting process improvement.
Work Piece Loading Systems
Including skip loaders, lift and tip loaders, vibratory feed hoppers, and other tools, work piece loading systems are ideal for small- to mid-sized work pieces handled in bulk.
True to our mantra of “finding a better way…” Rosler Metal Finishing is constantly working to optimize our consumables. These improvements and additions to our offerings improve process stability, cost efficiency, and productivity of surface finishing processes.
From media composition and compounds to wastewater handling, Rosler is dedicated to constant enhancement in the area of consumables as well as our mass finishing and shot blasting technology.
One such example is Rosler’s development of a plastic media with the grinding and non-chip characteristics of ceramic media. Minimizing the risk of work piece damage, this range of high-density plastic media exactly achieves this frequently requested combination.
Our Forge & Foundry Blog Series continues with an overview of our shot blasting machines most frequently used on these specific types of work pieces.
It is important to understand your work piece and process requirements including whether components will be processed continuously or in batches. When it comes to finishing forgings, non-sand castings, and powdered metal components, our shot blasting machines are divided into three categories based on how the work pieces are fed into the machine: continuous, batch, and specially engineered shot blasting machines.
Continuous Shot Blasting Machines
RMBD Continuous Tumble Belt Machine
The high-capacity, continuous feed RMBD is available in a heavy-duty version for large forgings and castings, which is equipped with 6 x 40 HP turbines, a steel-slatted work piece transport belt, and a magnetic separator.
Taking time to evaluate your process needs as a whole will help you and a trusted partner such as Rosler determine what machine and consumables will best suit your automation needs and goals.
How do I choose the right machine?
Selecting the right machine is the most critical step to ensure the success of any automation project. Without the right machine, your automation process is sure to fail or produce disappointing results.
The R 150 DL-2 was an excellent choice for LINK’s new “bi-mobil” hip implant. The implant offers patients a higher degree of mobility by inserting a movable PE joint in the acetabular cup. The PE-joint in turn is clamped to the ball of the hip stem. To minimize friction and prevent premature wear, the inside of the cup requires an extremely smooth surface, which can only be achieved with a high gloss polished finish—something the R 150 DL-2 easily achieves where other surface finishing companies failed.
With extensive experience in the forge and foundry industries, Rosler Metal Finishing understands that no two shot blasting processes and work pieces are alike. With that in mind, we continue our Forge & Foundry Blog Series with an overview of our machines offering excellent finishing for sand castings.
If you demand precise, repeatable results when shot blasting sand castings, consider the following machines. As always, the experts at Rosler are also available to develop a customized machine to accommodate your unique work pieces and challenges.
RMBD Continuous Tumble Belt Machine
The high-capacity, continuous feed RMBD is available in a heavy-duty version for foundry applications equipped with 6 x 40 HP turbines, a steel-slatted work piece transport belt, and a magnetic separator.
We’ve all heard the saying “If it’s not broken, don’t fix it.” At Rosler Metal Finishing, we often view automation as the solution—or fix, if you will—for mass finishing and shot blasting processes in need of added efficiency.
Both mass finishing and shot blasting are specialized processes that require a lot of practical consideration. Automating these processes can deliver great benefits to a manufacturer when properly targeted to a prescribed need, but, if the engineers developing the machine don’t understand your challenges, the solution is likely to miss its mark.
Available as rotary vibrators and centrifugal disk finishing systems, Rosler’s part-on-part finishing machines can accommodate various ammunition pieces including blanks, cups, deep-drawn casings, cartridge primers, and bullets.
While the manufacturing step and finishing operation of each component varies by work piece and desired result, common mass finishing operations for ammunition based on the specific work pieces are summarized below.
Crankshafts are an integral automotive component. Utilized to convert piston movement into rotational motion, these work pieces must provide reliable stability and withstand tensile, compressive, and shear stresses.
Let’s take a closer look at mass finishing
machines offering outstanding processing for crankshafts.
Built with specific work pieces in mind, Rosler designs
several machines to process crankshafts and other automotive work pieces.
Due to their considerable size and weight, the only mass finishing machines capable of handling the deburring of crankshafts after machining are mid- to large-sized tub vibrators or linear, continuous flow vibrators.
Selecting one machine type over the other largely
depends on the work piece’s size.
It’s hard to dispute that technology, on the whole, has made our lives easier and more convenient. Myriad functions have been automated – and improved – to mitigate the effects of human intervention. We make purchases more intelligently, we manage data more efficiently, we can control devices with our voices and eye movements, and we ultimately move through life with less left to chance.
In the world of manufacturing, this mitigation of human intervention promises even greater and more measurable, efficiencies. At Rosler Metal Finishing, quality improvements and cost benefits that have resulted from the mechanization and automation of mass finishing and shot blasting operations deliver dividends that transcend the manufacturing floor.
Since the first microprocessor-controlled machine appeared
on the manufacturing floor in 1974, hundreds of new varieties have been shipped
across the world. With each improvement, these automated attendants encompass a
larger footprint, are able to handle heavier loads and more axes, and require
fewer controllers to do their work, according
to a McKinsey study.
Automation has revolutionized smaller tasks as well,
including simple parts bin handling, lift assists, automatic media adding
systems, or multi-step process control systems (like those where noxious
chemicals are dosed, without human risk, into the process).
So how do these automation
upgrades pay off for you? Let’s start by taking a look at where mass finishing
and shot blasting has fit into the manufacturing paradigm. Then we’ll dive
deeper into the benefits of today’s automated processes which have a lasting
impact on the finished product.
