Preventative Maintenance Enables Mass Finishing Equipment to Go the Extra Mile

Mass finishing machines are workhorses of industrial finishing operations, combining engineering expertise and often a hefty price tag. When preformed according to manufacturer recommendations, preventative maintenance can make a big difference in the length of time between design and decommissioning.

Not convinced? Think of your mass finishing equipment like a vehicle. What would happen if you never checked the air pressure in your tires, changed the oil, or replaced the brake pads? Eventually your vehicle would leave you stranded on the side of the road through no fault of its own.

Mass finishing equipment manufactured by a proven expert such as Rosler is just the same as a vehicle that didn’t get the care it deserved. Without preventative maintenance, your high-dollar investment will break down. However, by performing preventative maintenance according to the manufacturer’s recommendations, your equipment will operate like a well-cared for vehicle, extending the life and return on your initial investment.

Diesel or unleaded fuel, anti-lock or drum brakes, manual transmission or automatic, preventative maintenance varies by vehicle type. Here are considerations for preventative maintenance based on your specific mass finishing equipment type.

Specifying Polyurethane Qualities Produces Mass Finishing Success

Polyurethane (PU) is an elastomer mix (urethane) material that can be formed into in a wide variety of shapes, sizes, and hardnesses. Its uses range from insulation and cushioning to adhesives and car parts and more. PU’s unique ability to withstand tension and compression while maintaining its shape and flexibility makes it a great lining for mass finishing equipment.

The ability to specify the size, shape, and hardness of PU allows equipment manufacturers like Rosler Metal Finishing to build machinery with custom inserts and linings to protect components and enable precise surface finishing as well as relining existing equipment with upgraded lining.

Our expert engineers create a custom blend of shore hardness, PU type, and forming method to produce durable and resilient materials that can withstand the harsh demands and stresses found within mass finishing operations.

Measuring Material Hardness

The shore hardness of PU is measured by the material’s resistance to localized deformation. This hardness or durometer is identified with a durometer tester, which forces a conical shaped indicator into the surface of the material and then measures the depth of the indentation. The scale ranges from 0-100 durometer with many different properties in between.

Part 1 – Vibratory Finishing Replaces Manual Finishing in Aerospace Industry

The aerospace industry  demands precision and high quality. The processes used to finish aerospace work pieces should adhere to the same rigorous demands.

Gone are the days when the surface of large structural aircraft components is frequently finished by hand. Thanks to the development of large, powerful vibratory tubs, costly manual deburring and grinding of large aircraft components can now be eliminated by highly controlled mass l finishing systems.

Finding A Better Way

Manual deburring and grinding are tedious and costly. Attempting these types of mass finishing by hand usually causes large quality fluctuations with relatively high scrap rates. Above all, manual processes demand highly skilled labor, which is especially hard to find in today’s economy and tight labor markets.

The lack of skilled labor and manual inefficiencies can lead to severe bottle necks in production and long lead times.

Optimized Finishing Processes Can Reduce Operational Costs

You don’t throw your media out with the waste water, so why would you purchase new mass finishing equipment or muddle through with an inefficient process when optimization can extend the life and enhance the effectiveness of your processing equipment?

Whether a result of increased production needs or in response to poor performance, optimizing your mass finishing process is a great way to reduce operational costs and lower your equipment’s total cost of ownership.

A Proactive Approach

Revising a process to meet increased production demand is a cost-effective way to not only improve your processing times and results, but also increase and prolong your equipment’s usefulness.

Let’s say production has been steadily building over time. How do you know if it’s time to evaluate the process?

Mass Finishing 101

Often overlooked in the manufacturing process, mass finishing can help add value in a variety of ways.  Mass finishing can reduce or eliminate manual process steps, improve process consistency, increase throughput, reduce manual labor, and more.

Manufacturing or process engineers in a manufacturing plant do not have to be the expert that knows all the latest details and techniques of the finishing process. They do, however, need to have a good understanding of the basic mass finishing processes that can be applied.

Mass finishing describes a surface finishing method where parts are deburred, smoothed, polished, or cleaned using media (tumbling or vibratory), compounds (finishing soap), and specialized equipment.

Examples of mass finishing equipment include:

Understanding how the different process components, i.e. the machine, media, compound, water, and the incoming part all interact and influence the desired part finish is important. Each of the inputs in itself has a multitude of adjustments and parameters.
