Automation Overview: TT20 Indexing Turntable Machines

Indexing Turntables are among the most common equipment to automate your blast operation. Their design has certain inherent features that promote versatility, ease and economy of operation. Such machines are often classified by their main table size, quantity of nozzles, and type of media propulsion, i.e. suction and pressure.

Empire TT Indexing Turntable Machines are manufactured in three standard versions, TT-20 (20″ diameter), TT-36 (30″ diameter) and TT-48 (48″ diameter). Our focus for discussion here is the smallest of the range, TT-20.

The TT-20 was designed with the goal of providing a cleaning or peening solution with all the versatility of an indexing turntable machine, all in a very compact footprint. The TT-20 is available to you with either four suction or pressure nozzles, as required by your application. The tenacity of your cleaning application, or the intensity requirements of your shot peening application will determine the choice of media propulsion.

As with all indexing turntables, in the TT-20 loading/unloading of parts takes place under the cover of blasting.

TT20 Peening System Small Footprint

The engineers at Empire place special emphasis on your individual requirements, whether it be space constraint in your plant or a special technique in your manufacturing process requiring the inclusion of additional process control components in the TT-20. In the current example (see insert), the TT-20 performs a critical peening operation on aerospace components requiring a vibratory classifier, multiple outlet pressure vessel and dust collector, all in a very compact footprint in order to fit customer’s existing plant layout and constraints.

Industry and Applications:

  • Medical : A relatively recent adopter of blast cleaning and shot peening processes leaves our customers in the medical industry with very limited space availability. With a minor table modification to the TT-20, it can be upgraded to a 12 station configuration, producing two cleaned or peened medical component with every index of the main table.
  • Aerospace: When processing of small blades with vent  / cooling holes, the TT20 provides a pressurized part rotation station that blows air up through the blade to and prevents media from staying lodged in critical internal areas. In the absence of such an arrangement, the blast media has a tendency to clog the holes resulting in a scrap part.
  • Automotive: Small transmission components
  • Friction parts
  • Cylinders for airbags
  • Brake rotors

The blast system is regularly replenished using an automatic Make-up Hopper. This hopper adds virgin media to the system whenever the storage hopper runs low on media. This controlled replenishment helps maintain proper operating mix resulting in a consistent part finish.

Safety:
The TT20 offers many safety features including:
o    Light curtains at load/unload station
o    Door safety interlocks
o    Door locks (if needed)
o    Vertical sliding doors

Eliminate The Guesswork Out Of Cleaning And Peening

Welcome to the most sophisticated and comprehensive test facility for airblast peening and cleaning applications. Welcome to the Demo Center at Empire in Langhorne, PA (USA).

Whether you are an existing user of cleaning or peening equipment, or a novice to the process, the Empire Demo Center has tremendous potential with tips to increase your productivity and add to the profitability of your operation.

As an advanced manufacturing plant, you have other critical parts of your production process that demand your attention. Most often, this results in an unintentional neglect of processes such as blast cleaning and shot peening. Interestingly, this neglect could lead to higher operating costs and equipment wear than normal. Let’s take the instance when your customer has introduced a new product and would like to partner with you and develop the cleaning or shot peening specifications and procedure for this new component. Empire is here to help with its demo center in both instances. Here’s how:

  • Review your existing application and equipment use with Empire by testing your production parts in one of over ten machine types on Demo Center.
  • Demo results could prove that maybe you have been using higher blast pressure than required, perhaps a different media type or size could provide you better results. Both changes will reduce your operating costs.
  • The Demo Center has equipment with varying and increasing degrees of automation. If your new production needs demand a slightly higher degree of automation, the Demo Center provides you the choice of equipment to test the same.
  • Shot peening is a process that’s either misunderstood or completely new to a lot of end users. Visit the Demo Center. Our experts in this process will carry out peening tests on your part samples, to varying levels of impact energy (shot peening intensity), that you will be able to conduct fatigue tests on at your plant. Along the way, we will also help you develop your peening parameters and even help you conform to an established specification.

Empire Demo Lab

The Empire Demo Center has the entire range of airblast equipment available for tests, starting from the simplest manual handblast cabinet to sophisticated robotic cells for single part flow. All this equipment is available for your testing, most times without any charge.

We look forward to seeing you in our Demo Center and help you increase the profitability of your cleaning and peening operation!

What Is The Difference Between Pro Finish and ProFormer Systems?

The difference between a Pro Finish system and a ProFormer system is that the ProFormer is an all-in-one unit with only two connections required: air & electrical. The ProFormer cabinet is designed for production blasting and enables you to perform multiple tasks. You can clean, peen or prep for a coating by simply varying air pressure and blast media. The cabinets can be specified with suction-blast or pressure-blast systems and have a wide range of standard factory options.

Applications that work well with this cabinet include:

  • Scale removal
  • Surface profiling (etch)
  • Rusty parts
  • Stripping powder coatings
  • Add matte or satin finish
  • Remove glare or imperfections

Rolling turntables, designed to expedite loading and processing, are just one of many standard factory options available with ProFormer™ cabinets.

To help provide customers with the right solution, Empire can perform test blasting to determine if the process requires suction or pressure blasting. This also enables us to get all of the customer’s potential part sizes and the required blast area matched to the proper cabinet.
