Part-on-Part Mass Finishing, Part 2 – Rotary Vibrators Versus Centrifugal Disk Machines

As described in Part 1 of our Part-on-Part Blog Series, some forms of mass finishing techniques encourage part-on-part contact to achieve the desired finish. 

In addition to viewing work piece impingement as an asset, this type of mass finishing also eliminated the need for ceramic, plastic, and other types of media. The only additives required for such part-on-part finishing are water and the respective compounds.

Rosler Metal Finishing designs and manufacturers two machines specifically for part-on-part mass finishing known as WTA rotary vibrators and MK centrifugal disk machines.

The applications and benefits of each machine provide a range of part-on-part mass finishing uses for sturdy parts in bulk. Let’s compare their designs.

WTA Rotary Vibrators

Rosler developed special WTA rotary vibrators especially for part-on-part processing. These machines not only allow running the finishing/washing process, but also the subsequent drying stage in one single machine.

Automotive Crankshafts, Part 2 – Shot Blasting Machines Designed for Crankshafts

As established in Part 1 of our Automotive Blog Series, “Cost-Effective Surface Improvement for Key Engine Components,” shot blasting is an effective technique for the surface treatment of automotive parts including crankshafts.

Used in heavy trucks, heavy equipment, and, even, large ships, crankshafts enable an engine to move a vehicle by converting the reciprocating (up/down) movement of the pistons/connecting rods into a rotational movement that propels the vehicle forward.

Depending on their size, weight, and production volume, crankshafts can be blast-cleaned in different machines. Rosler Metal Finishing offers solutions for a wide range of crankshaft types with weights from 15 to more than 500 lbs and lengths from 10 up to 80 in and more.

Typical Machines

Built with specific work pieces in mind, the machines designed to process crankshafts are as diverse as the work pieces they accommodate.

Automation, Part 1 – How Robots Are Improving Mass Finishing and Shot Blasting Processes

Automation is changing the way mass finishing and shot blasting processes are delivered. In this five-part blog series, Rosler Metal Finishing will explain what has given rise to automation trends, the human factors of these manufacturing upgrades, and how such automated processes deliver benefits to your business.

Those of us of a certain age remember a portrayal of robotics that, in hindsight, was rather quaint: human-looking automated machines would be crisscrossing our landscape, delivering us food and wardrobe, pumping our gas, collecting our garbage, or – in a more macabre rendering – leading a rise of the machines that would eliminate the human race.

In reality, Rosie the Robot and the Terminator have not ruled the world, as predicted by Hollywood. Today, faceless, automated machines, arms, and processors are streamlining the way in which products and services are delivered.

In fact, a World Economic Forum article found that the 2020s will be the “age of automation,” with manual jobs making up only 35 percent of the manufacturing labor force by the end of this decade (a drop from 48 percent, as measured in 2016).

Part-on-Part Mass Finishing, Part 1 – Utilizing Work Pieces as the Media

Mass finishing processes require pressure and constant rubbing to achieve the desired finishing results. In most cases, these applications require media specifically selected for its material, size, and shape to act upon work pieces and achieve the required effects. Some mass finishing applications also seek to eliminate or reduce part-on-part impingement or contact to protect delicate and high-value work pieces.

Conversely, part-on-part mass finishing intentionally exposes work pieces to impingement and encourages contact between work pieces and the resulting pressure to create finishing effects without the need for ceramic, plastic, and other types of media. The only additives required for such part-on-part finishing are water and the respective compounds.

Rosler Metal Finishing designs part-on-part mass finishing machines, known as WTA machines, which help reduce cost per piece through the elimination of media consumption and faster processing times.

Ideal Work Pieces

Part-on-part finishing is ideal for small, bulk parts that are made of brass, steel, aluminum, and even small ceramic components.

Automotive Crankshafts, Part 1 – Cost-Effective Surface Improvement for Key Engine Components

Crankshafts are a key component of internal combustion engines, be it mass-produced engines for motorcycles and automobiles, engines for heavy trucks, off-high highway equipment, and even large ships.

Crankshafts convert the reciprocating (up/down) movement of the pistons/connecting rods into a rotational movement that drives the wheels and allows a vehicle to move forward.

Rosler Metal Finishing understands the vital importance of these engine components and has developed specific shot blasting and mass finishing machines to process these pieces to perfection.

Materials & Production Methods

Considering that automotive crankshafts weigh around 40-60 pounds and rotate approximately 100 times per second, these parts are exposed to tremendous tensile, compressive, and shear stresses. In addition, combustion forces and piston acceleration in an engine can also cause significant vibration.

Therefore, crankshafts must be made from tough, wear-resistant materials, usually high alloy carbon steel. Typical alloying elements are manganese, chromium, molybdenum, nickel, cobalt, or vanadium.
