Sculpting the future: speeding machine, digital transformation
Fueled by visionary thinking and ingenuity, TARUS remains the leader in car design studio solutions. To maintain market dominance and meet accelerating customer demands, TARUS ownersโand brothersโDave and Doug Greig realized they needed to elevate and enhance the capabilities of their clay milling machines.
TARUS found answers in the equally innovative, revolutionary SINUMERIK ONE machine control from Siemens.
With full milling and scanning capabilities for the sculpting of concept vehicle designs, this groundbreaking CNC milling machine set the tone โ and a high bar of expectationsโfor TARUS that guides its leaders to this day.

Invention and innovation are the lifeblood of family business TARUS, the only U.S.-based manufacturer of clay milling machines for vehicle design.ย In 1984, the Sterling Heights, Michigan-based company completely changed the automotive industry when it introduced the world to its invention, the Claymillโข. With full milling and scanning capabilities for the sculpting of concept vehicle designs, this groundbreaking CNC milling machine set the toneโand set a high bar of expectationsโfor TARUS that guides its leaders to this day.
Realizing success in self-control
Equipped with this in-house, in-demand control and its successors, TARUS-built machines were fast, smooth, accurate, and reliable. Customers loved the look of the controlโs interface and the machinesโ reliable, repeatable results. In 1984, TARUS and General Motors teamed up to develop a portable clay milling machineโthe worldโs first purpose-built industrial clay milling machine. The TARUS Claymill quickly became the automotive industry standard. These machines mill clay, dense foam, and polyurethane for design and surface verification models for future vehicle designs.
As its success bred more success, TARUS spent the ensuing decades as the global leader in car design studio solutions. With the auto industry evolving to incorporate electric vehicles and its competition growing, TARUS took another leap forward. Further enhancing the capabilities of its industry leading graphical user interface, TARUS adopted the SINUMERIK ONE control, merging reliability and performance with the functionality and user friendliness of the TARUS Claymill CNC.
โSINUMERIK ONE came at the right time,โ Dave Grieg said. โWe were looking to make a change that would bring added performance while also allowing us to keep our graphical user interface designed for clay modelers. That gives us our edge. With the Siemens control powering our machines, modelers can do things they never could do before.โ
“Now we have an extremely high-performance CNC machine control with our user interface, which customers love, and itโs very easy to use.”
โ Doug Grieg, co-founder, TARUS Products, Inc.
Finding another gear
Timing was key to the TARUS-Siemens partnership. Scott Doyle of Electro-Matic, the trusted solution provider and technology partner of TARUS, knew the needs of his client.
โUnderstanding exactly what TARUS does and its superior motion controlโa lot of what TARUS was doing was right up Siemensโ alley,โ said Doyle, vice president of OEM sales at Electro-Matic. โThe opportunity was crystal clear.โ
Doyle introduced Doug and Dave to Siemens technology and were assured the multi- technology SINUMERIK ONE could boost the performance of TARUS machines while retaining the companyโs cornerstone graphical user interface.
โWe took the SINUMERIK ONE package, we implemented it, and we tweaked it for our interface,โ Doug said. โNow we have an extremely high-performance CNC machine control with our user interface, which customers love, and itโs very easy to use.โ
Customers using the TARUS Claymill for their life-size vehicle models are โecstatic,โ Dave added. โItโs solid, it runs a lot faster, itโs smoother, quieterโeverything. The machines are running consistently and reliably.โ
Boosting manufacturing performance
TARUS and its customers are now realizing benefits across the production cycle, from machine setup and customization to machine performance and throughout.
Most important to Dave, Doug and their customers is the familiar look and feel of the TARUS control. This was their biggest concern and biggest question when adapting TARUS machines to SINUMERIK ONE. The process took about one year, involving collaboration between Siemens and TARUS staff, and the results are unrivaled in the industry, Doug said.
โNobody has the user interface like we have with the reliability of SINUMERIK ONE. Thatโs the secret sauce,โ he said. โBecause we already wrote our own software for our own control, we were able to make these two things work together for our customersโ benefit.โ
Users experience the trust and familiarity of the TARUS interface, but with superior machine performance.Surface quality, precise cuts, cycle times, and reliability are critical to TARUS and its customers as they mill the clay into future vehicle models. In fact, it is the precision of the cutting tools that produce desired surface finishes and eliminate time-consuming hand sculpting.
Dave said customers who use TARUS machines as an extension of their own design sculpting teams are indeed achieving a higher-quality surface that rarely requires smoothing by hand.
“Our machines cut so precisely now that they donโt have to refine it, itโs saving them valuable time.” โ Dave Greig, TARUS CEO
Faster cycle times
โIn processing power alone, SINUMERIK ONE is 30% faster,โ said Chris Grimm, OEM sales account manager at Siemens. Testifying to that claim, Doyle has seen the results first-hand with TARUSโs internal machines. โTheir throughput has increased tremendously,โ he said.
Customers are saving even more time during the design and milling phase of the car models, as the TARUS software enables changes on the fly.
Doug explains: โWith our software, customers have a choice. They can mill a car model, and if they want a small change, they can sculpt it by hand, then measure it. They can scan it with their scanning system, then they can mill it on the other side of the model. Or they can send it back to their CAD system so that theyโve archived the change. Sometimes, they decide to make the change with the machine.โWe take the settings from one machine and put them on the next machine, turn it on, and it works,โ he said. โEvery machine acts just the same as the one we just built.โ
Ensuring a productive future
Although Dave and Doug are focused on the here and now, ensuring immediate results internally and for their customers, they also are thinking long-term. Thatโs another reason the brothers felt comfortable switching from an in-house control.
As a relatively new innovation built upon a legacy of success, Siemens will support SINUMERIK ONE for many decades to come. TARUS and its customers will have no issues obtaining new parts or customer serviceโfrom both Electro-Matic and Siemens. โThe availability of replacement parts for years to comeโthatโs a big deal,โ Doug said. โWhen the parts come in, we know theyโre going to work. Theyโre plug-and-playโand Siemens maintains the supply chain too.โ Customer support is a collaborative effort between Electro-Matic and Siemens. Electro- Matic has in-house application engineers who can visit TARUS and provide product support up to a certain level of complexity before bringing in the support of the local Siemens application engineer, Doyle said.
As a pilot customer, TARUS was one of the first U.S. machine builders to take advantage of the power and capabilities of SINUMERIK ONE. That gave the company a jump-start on the marketโand it has kept its foot on the gas ever since. โOur competitors donโt have anything like this,โ Doug said. โIf you compare our machines, bone to bone, to any other thing out there, itโs not even close. Everyone else is making what we made 30 years ago,โ Dave added. โThatโs the difference.โ
As beneficial as the switch to SINUMERIK ONE has been for TARUS, thereโs room for more growth. The control package has features and options TARUS has only begun to explore, options that are particularly well-suited for other markets, including aerospace. Doug hasย already thought about expanding into manufacturing CNC machines for customers that make parts for the aerospace industry.
No matter the market, features of SINUMERIK ONE such as the digital twin can play a part. The digital twin is a virtual representation of a physical machine or process used to understand and predict the physical counterpartโs performance characteristics. Digital twins are used throughout the life cycle to simulate, predict, and optimize the product and production system before investing in physical prototypes and assets.
โLeveraging the digital twin and running parts virtually first before you actually put them on the machine so they can get accurate quotes for how long it might take for end- customers to do a mold or a die is a powerful option,โ said Brian McMinn, business segment manager of Machine Tool Systems at Siemens. โTraining benefits from the digital twin as well. TARUS can train customers virtually before the machine even arrives at their location.โ
The possibilities are appealing to Doug, especially in how TARUS supports its customers. โ100% remote monitoring and repair of the machine is 100% possible,โ he said.
Powering Innovation for Years to Come
Building on its storied past, TARUS has successfully added a pivotal piece to its foundation. With SINUMERIK ONE, the company has elevated its ability to innovate and remains a versatile industry leader with superior clay milling capabilities for its customers. And the TARUS evolution will continue. Dave and Doug, along with Electro-Matic and Siemens, are gearing up for even more advancements.
At Siemens, the design and engineering teams are learning more and more about TARUS and its desire to push the envelope, opening up the SINUMERIK ONE playbook. Nothing, seemingly, is off the table for this innovative trio of companies.
Knowing TARUS wants the control to be one of the differentiators for its machines, McMinn sees software efficiencies on the horizon that can help improve production. โTARUS is always looking at different features, different software licenses or compile cycles to get more productivity out of the control,โ he said. The reliability of SINUMERIK ONE frees up TARUS team members to implement improvements and customer-requested advancements since they donโt have to worry about the technology driving the machineโs performance. โNow TARUS is freed up to develop other features that are more interesting and more relevant for our customers,โ Doug said. โLike enhancing the graphical user interface or optimizing the CAM system that programs the user interface.โ For now, though, Doug knows the decision he and his brother made years ago is paying off today for TARUS and its customers.
โJust as dynamic new car designs are imagined and realized, TARUS and Siemens are re- imagining and innovating machines, controls and processes that help bring visions to reality,โ he said. โThis is truly an exciting time for manufacturing.โ
