The Importance of Vibratory Finishing Chips, Compound and Their Production

Range of compounds and media

The quality of consumables used in mass finishing is a key factor in surface processing.  Using consumables with a consistent high quality is crucial to attain set surface specifications, process times, costs and to manage considerations to any environmental impact.

There are in excess of 1700 types of vibratory media consisting of various shapes, sizes and incorporating a percentage of abrasive.  These are divided typically between ceramic and plastic families.

Ceramic Media Production

Ceramic media

Ceramic media

A ceramic media has a higher density than that of plastic media.  Ceramic chips of various shapes and sizes are formed, fired and held at certain temperatures and durations; providing an infinite range of variation and capability.

A consistent, supreme quality media is extremely important for the user to obtain a uniquely stable and reproducible surface finishing result.

Ceramic media is manufactured to exacting standards, controlled  in a fully-automated way.

Plastic Media Production

Plastic media

Plastic media

The manufacture of the plastic media is also totally automated.

The plastic media is of a lower density than that of the ceramic media, therefore it is suitable for a more gentle treatment of  critical component parts and softer metals.

The process involves mixing, forming and curing of the media and the whole process is computer controlled and continuously monitored.  This quality standard ensures a consistent wear and cutting performance, and repetitive results during the finishing process.

Surface Finishing Compounds

The right compound for any mass finishing application

Compounds can be added to the vibratory process, optimising the surface specification for: degreasing, brightening, polishing, corrosion protection and producing surfaces free of stains.

Another important function is keeping the process clean.  The compound continuously flushes tiny metal particulates from the chip media and other contaminants out of the mass finishing system, keeping the media active and the parts free from contamination.

Depending on the specific process, compounds will provide various options of acidity and alkalinity as a pH factor.

Despite compounds being used for many years in mass finishing applications research and development constantly progress new formulations for special applications.

The range of different compounds is broadly diversified:

  • Liquid compounds
  • Recycling compounds
  • Powder compounds
  • Grinding compounds
  • Polishing compounds
  • Dry-polishing compounds
  • Cleaning (degreasing) compounds

How To Ensure You Get The Maximum Performance Out Of Your Blast Wheel

Rutten “C” and “Y” Blast Wheel Turbines

c_bladey-blade

The Long-life Rutten has the longest ultimate life expectancy of any, lasting upto 20 times longer than a standard blast wheel or turbine.

This is a highly-engineered blast wheel with exceptionally tight tolerances and built-in specialist superior steel alloys.  Due to the higher value materials and the high specification machining costs of these materials, the initial investment and cost of component wear parts are more highly valued.

However, if maintenance and/or production problems are presently a big issue, the economics of this blast wheel can be demonstrated in ultimately high production speeds and demanding applications.

Least Maintenance And Highest Specifications

Less costs for maintenance up to 16 times higher wear resistance and service life of up to 40,000 operating hours (over 18 years on a single shift).

rosler-gamma-y-wheel rutten-y-wheel

The proven Rutten Long-Life turbines, equipped with components made from carbide steel are characterised by their extremely long service life of up to 40,000 operating hours resulting in significantly higher equipment uptimes and drastically reduced time requirements for maintenance.

They offer substantial savings in energy consumption and spare part costs/hour. The blades have a precise design with a high recognition value and in addition allows the “Y” blade to be turned and used twice. Long-Life turbines are installed in a wide range of new shot blast equipment and can be easily retrofitted into existing shot blast machines.

Polishing of Automotive Wheels

Alloy Wheel polishing has been significantly improved by optimising both the processing times and final results. These improvements have been achieved by mounting two motors on the process bowl, providing a stronger and uniform circulation of the grinding and polishing media.

Conventional machines have only a single motor in the centre and on more complex designed alloy wheels, additional machine inertia is desirable.

Replace Blast Wheels and Wear Parts

PART 1             The Case for Superior Blast Wheel / Turbine Efficiency

Your blast wheel is the “business end” of you shot blast machine.   It is the main component which delivers the blast media and performs the blast cleaning or peening process.rosler-gamma-y-wheel

Its performance is vital!

Not only is the blast wheel vital, it is probably the more expensive single item on the machine in terms of performance, productivity, time, maintenance, repair and wear part costs.

Focusing on your future

Retrofit Blast Wheels And Wear Parts

PART 2   The Case for Superior Blast Wheel / Turbine Efficiency

Less energy consumption up to 25% cost-savings and compliance to environmental policy.

Depending on the size and type of shot blast process i.e. type of machine – Table, Hanger, Barrel, or Through Conveyor, the cost of running per hour adds up.

A simple small table or hanger machine may pull between 11 amps to 60 amps / blast wheel.  A single blast wheel will require 5.5kW to say 30Kw.  Using a nominal 10p / kW hour, costs range from 55p to £3.00/ blast hour x 2,200 hours / annum equates to between £1,210 and £6,600.

Replacement Blast Wheel And Spare Parts

 PART 3         The Case for Superior Blast Wheel / Turbine Efficiency

Our / Your Aims

To reduce to a minimum the amount of maintenance labour required on the blast wheel.  By placing superior quality spare wear parts into the blast wheel, that will sustain and maintain the blast pattern between 2 and 20 times longer, depending on your application, choice of blast wheel and abrasive type employed.

Reduce the number of wear parts required to be purchased per annum, by making the spares of higher quality material and design, which wear at a much slower rate, and maintain their integrity for very much longer.
