SURFACE FINISHING SOLUTIONS FOR THE

Company’s test trial laboratories andcenters of excellence are located inGermany, United Kingdom, Slovenia,USA, Canada, Turkey and it is underconstruction in Queretaro, Mexico.

All locations are set up to performsurface finishing process trials oncustomer's components and providefull after sales support that includesservice, spares and a comprehensiveinventory of abrasives.

Massfin Inc. is a one of the leadingNorth American supplier andmanufacturer of surface finishingtechnology, machines, consumablesand process water treatment solutions.Our aerospace division, MassfinAerospace provides technology,machines and processes such asvibratory finishing, shot peening, wetblasting, coating, high pressure waterjet blasting, paint stripping/coatingremoval and general surfaceroughening.

Massfin Aerospace finishing process technology is used for avariety of aircraft engine parts, landing gear and airframe

components.

We do work with and represent exclusively major surface finishingtechnology giants as Walther Trowal, Vapormatt, Ferro Eco Blast,

and Massfin VM/Vibromak.

Turbine components like fan blades,compressor blades, blisks, turbine disks,engine casings, etc., require a perfectsurface finish with low Ra readings.

These are achieved by processing theparts in top of the line rotary vibratorsequipped with the “gate clearing” featurefor gentle and 100% unloading of theparts from the finishing machine.

For somewhat more intensive finishingprocesses high performance Turbotroncentrifugal disk finishing machines areutilized.

And, the eco- friendly Trowapast finishingprocess produces surface finishes with Rareadings of <= 0.2μm.

Massfin Aerospace represents WaltherTrowal, a company building vibratoryfinishing machines since year 1931.

Since then the company has become thetechnological market leader in the surfacefinishing industry by building a reputation ofproducing first class finishing equipmentfeaturing state of the art engineering andsturdy design.

With the knowhow accumulated for over 8decades, Walther Trowal provide specialsurface finishing solutions that are customengineered to match customer’stechnological requirements.

ENGINEPARTS

Focus of finishing technology is divided in threeaerospace segments:

V i b r a t o r y f i n i s h i n g

Walther Trowal technical development of theMulti Vibrator MV, allows the intensive finishingof the inner and outer surface of hydraulichousings. This versatile vibratory system is alsoideally suited for processing delicate componentswhich must not touch each other during thevibratory finishing process.

Walther Trowal also offers solutions for coatingof mass produced bulk parts like screws, rivets,etc. Such bulk parts can be efficiently coated in“Rotamat” coating systems for corrosionprotection, visual differentiation and thedissipation of static electricity.

Trowal tub vibrators allow the efficient, costeffective finishing of the surface of large structuralcomponents used in wings, fuselages and landinggears with lengths of up to 6,000 mm (20 ft) and amaximum width of 1,300 mm (4.3 ft).

The proven “multi vib” vibratory drive systemguarantees an even, intensive movement of themedia mass over the complete length of thevibratory tub producing an absolutelyhomogeneous finish on the parts surface.

Close customer relations are asimportant to us as the quality anddurability of our products

The development of optimumsurface finishing solutions in closeconsultation with our customersand continuous customer supportare key elements of MassfinAerospace company philosophy.

Of course, Massfin Aerospace alsooffers economic solutions forvibratory finishing featuringVibromak mass finishing machines.

Vibromak machines are used forfinishing of large structures on bothnew and re-built aero engines, airframes and landing gears. Vibromakmanufacture high quality andaffordable finishing machines.

Massfin Aerospace vibratoryfinishing machines are built to

With quality being synonymous with allaerospace work there is a good reason whythe aerospace industry looks to Vapormattfor surface processing solutions. With aVapormatt system you can ensure the levelof finish will meet the high standards set byaerospace companies.

Having worked extensively with severallarge aerospace firms Vapormatt havedeveloped a range of systems that offerconsistent and repeatable results using thewet blast process. Results which are vitalfor maintaining integrity within theproduction chain.

Through a collaborative and consultativeapproach with our aerospace customersVapormatt have been able to providesuccessful wet blast solutions to meet arange of applications such as: shot blasting,wet peening, surface preparation, paintstripping, degreasing, compositepreparation, deburring, abradable coatingremoval and much more.

The surfaces treated by the wet processcome close to perfection as far asphysical/chemical cleanliness is concerned.This process is particularly suited to thetreatment of delicate, precision machinedparts.

Special wet process systems are fitted withautomation systems or numerical drivensystems to control the blast nozzle'smovements as well as the handling of thetreated parts.

The main advantages are:

No dustAbility to use very fine abrasives.Reduced fragmentation due to the water film (ideal for shotpeening using glass beads).closed loop control for shots/blasting media flow formetallic and non-metallic mediaCNC or PLC control of nozzles or piece holdershigh accuracy and high reproducibility of processparametersquality built equipmentsoftware system for process monitoring (statistical processcontrol) and documentation

Shot peening in aerospace industry requiresabsolute accuracy and repeatability. Specialautomatic shot peening process with therobot shot peening system is developed byFeroEccoBlast. OEM manufacturers and MROproviders use shot peening technology for therepair and maintenance of all types of landinggear and engine components. Fullyautomated, PLC or PC controlled machinesmeet all technical requirements andspecifications for shot peening in Aerospaceindustry

Keeping in mind challenging geometries oftypical landing gear and landing gearcomponents a customized multiple toolingsystems was developed by Ferro Eco Blast.

For smallest and most precise ID a roboticmanipulated rotating lance was installed.Lance design incorporates servo mechanismalways driving small lance with stable pre-setvalue of RPM. This combining with accurateindexing table presents ideal solution notonly for landing gear ID but also for otheraerospace components such as LPTs or otherobjects containing small sized grooves andapertures. A large automatic horizontalrotating lance is programmed to peen the IDsurfaces of largest parts.

Ferro Eco Blast is business ofbuilding shot peening machines

and developing shot peeningtechnology since 1964.

Quality of consumables used in aerospacevibratory finishing process is a key factor.Quality determines process time,throughput, process costs and theenvironmental impact of the process. Ourproduct range of different types ofceramic and plastic media is unique interms of variety and quality. In addition toour standard products, we are constantlydeveloping new products for newapplications and customers which requirespecial solutions.

Liquid and powder compounds, as well as drying andpolishing media are also part of Massfin Inc. range ofconsumables. We only work with environmentallycompatible raw materials and place high ecologicalrequirements on the production of our consumables.
