Test Devices 2018 Year in Review

2018 has been a banner year for Test Devices, with expansions in both our facilities and our services, allowing us to better serve our customers as a “dependable partner” and a convenient “one stop shop”. Some of our new and expanded service offerings include in-house machining, eDrive spin testing, and expanded balancing capabilities – thanks to the acquisition of a new Schenck balancing machine.

Facility Updates 

Test Devices’ latest facility upgrade brought significant improvements to our shipping and receiving departments and upgrades to our climate-controlled precision inspection room, which includes the expansion of our Quality Inspection team and the acquisition of a new larger CMM (coordinate measuring machine).

The redesigned facility layout, added floor space, and new equipment allowed us to streamline our workflow and enables us to work more efficiently than ever before. The new shipping and receiving departments are now located to the front of the building with an expanded floor space, and optimally equipped handling areas with additional cranes and staged operations. This new layout minimizes unnecessary movement, creates easier access and an unobstructed flow of materials.

We have also expanded our equipment build area and relocated it to a new section of our facility. This move allowed for a more efficient staging of equipment builds and assembly operations capable of preparing three to four machines simultaneously.

Semi-Finish Machining

As of June, Test Devices now offers in-house semi-finish machining services for aerospace turbine disks. For over a decade, TDI has served leading jet engine OEMs who require forging pre-spinning services—a vital part of producing nascent engine disks that offer the highest performance. While a seemingly simple process, this service is deeply specialized, demanding the highest knowledge and skill level to produce a seamless operation. This newly added machining capability will vertically integrate operational steps and allow TDI to offer more expeditious and higher quality services. By the end of 2018, TDI is on track to ship over 100 semi-finished forgings.

Expanding Aerospace Grade Balancing Services

In 2018, Test Devices grew our balancing capabilities by acquiring a new HM 20 Schenck Horizontal Balancing Machine to support the growing demand for these operations. This high precision, state-of-the-art machine allows TDI to service a broader range of customers with varying rotor balancing needs.

Among the primary benefits of the HM 20 is its hard-mounted bearing design, ensuring rapid changeovers between rotors, which allows Test Devices handle significantly higher volumes of balancing jobs and increase the efficiency of our operational capabilities. The HM 20’s modular design also allows it to be easily modified.

Growth in eDrive Spin Testing Systems

The successful completion of an increasing number of proof and burst tests and 130,000 LCF cycles in 2018 attests to the growing demand for eDrive testing.

We are continuing to enhance our testing and engineering offerings to support eDrive customers in 2018, including advanced rotor growth mapping, high-resolution, high-speed video imaging, expedited fatigue, LCF tests (with RT-CDS and growth mapping), heated spin tests, unbalance budgeting and rotor design engineering support.

Adding the rough machining capability onsite now allows us to offer shorter turnaround times and higher overall efficiency, ensuring clients’ specific needs are met as smoothly and quickly as possible.

The forging pre-spin process may seem easy at first glance, but it’s actually a highly specialized service, and requires a true expert to ensure flawless operation. These professionals must oversee:

  • Proper spin tooling design for repeated use
  • Commissioning & pilot runs
  • Confirmation and monitoring of accurate disk growth amounts
  • Troubleshooting for rotor dynamics issues
  • Optimizing and troubleshooting quality process-related issues

Reliable Supply for Rising Demand: Preparing for Increased Aircraft and Engine Sales

The demand for aircraft continues to grow, supporting the need for increased air travel. This trend is expected to continue its upward trajectory over the next 15 to 20 years; translating to continued growth in aircraft and engine sales from lead OEMs — as well as an increased need for critical spare parts that require pre-spin and rough machining. Engine turbine disks, for instance, must undergo these processes to ensure optimal performance and safety.

By bringing rough machining in-house, TDI will reduce both costs and turnaround times for our customers, and overall flexibility and responsiveness will be significantly improved. We are well-positioned to meet the rising demand.

Test Devices Inc.’s Improved Capacity

Over the last year, Test Devices has seen a significant influx in the volume of parts that our facility processes on a weekly basis. This increased demand pushed us to re-evaluate whether our methods were providing the best possible experience for our clients.

We’ve made several adjustments to our processes in order to improve turnaround time, capacity, and overall customer experience. We’ve already started to roll out many of these changes, and you will begin seeing them take effect in the coming weeks. The most notable areas of change are:


Many of the parts we process require that a precise measurement be taken both before and after the spin test. In January 2017, we installed a 2nd CMM (scans parts up to 48” diameter) that not only allows us to inspect larger parts, but to inspect multiple parts simultaneously as well.



Spin Rigs

In 2016, we dedicated (2) spin rigs to be used solely for the support of pre-spin and overspeed spin testing. We are also retrofitting another existing machine (available mid-April). With the addition of this machine, we will have a total of (3) machines dedicated to our pre-spin and overspeed spin testing, and Test Devices will be able to better dedicate rigs for specific speeds and part types – ultimately significantly reducing setup times.



Test Devices has added additional personnel to support two shifts of operation in both spin rigs and CMM inspection. We are actively looking for additional candidates as the 3rd spin rig comes on-line.


5S Activity

Last year, Test Devices acquired additional space within our facility, and we immediately went to work to determine how it could be used to maximize efficiency and improve part flow.  A thoughtful reorganization of our layout freed up a significant amount of room, which is now expressly dedicated to handling the increased volume of pre-spin and overspeed spin testing.


Improved Scheduling

We have recently instituted the use of a whiteboard to improve scheduling and better ensure we meet customer commitments.
