About TARUS. The original Claymill™ and still the best.

TARUS revolutionized transportation design by inventing the world’s first Claymill™ in 1984, in partnership with General Motors.
 
It was unveiled with tremendous fanfare and brought to the Waldorf-Astoria for display at GM’s “Teamwork and Technology for Today and Tomorrow” event – still the largest display of GM technology in company history. TARUS clay mills were also showcased for their futuristic capability in EPCOT Center’s “World of Motion” attraction from the late 1980s through the early 1990s.
 
The TARUS Claymill™ created a new category in the machine tool business. It was the first in-studio, on-plate, portable, 5 Axis CNC milling machine produced for clay models that had full milling and scanning functionality. The TARUS name quickly became synonymous with clay modeling. Generations of automotive sculptors referred to clay milling CNC machines simply as a ‘TARUS’ or Claymill™.
Today, TARUS remains the preeminent global leader in cutting-edge clay milling machines and comprehensive car design studio solutions. TARUS currently builds the largest variety of machines with greatest performance, capability, ease-of-use, and reliability of any supplier.

The TARUS Advantage

TARUS is one of the few manufacturers of high-precision, large volume 5-axis CNC machines for heavy industry in America.

 
Our machines are legendary for their durability and toughness. Starting with raw materials, we build all of our machines in-house from scratch. A number of TARUS machines are running after almost 50 years of daily use. We build machines that will last for generations.
 
Our history building large, tough, precision machines for heavy industry has made our Claymills just as legendary. Some TARUS Claymills built in the 1980s are still running after 40 years of daily use – often outperforming some of our competitors’ current offerings.
 
When we build machines that are meant to last for generations, it starts with a strong, robust design build. Greater structural integrity means a more rigid Claymill, directly translating into the best surface finish in the industry.
 
A stronger, more robust structure also means higher performance. TARUS Claymills can handle a larger milling head, more powerful components, faster speeds, and provide a nearly silent operation.
 
Our heritage of building computer controls in-house was the basis for tremendous software innovation. The TARUS Claymill user interface was specifically built around the needs of modelers and sculptors. Our UI is renowned in design studios and widely regarded for its ease-of-use and functionality.

About - History of Innovation

1969 - TARUS is founded

TARUS Products, Inc. was established in 1969 by Douglas J Greig in his Warren MI garage, building EDM servo controllers. It was one of the first electronic systems to automate control cycles of EDM electrode ram.

1971

TARUS continues upgrading EDM controls and power supplies for EDM retrofits, bringing generations of older machines into current performance specs. Success with EDM control and retrofits allows expansion into a dedicated factory manufacturing complete EDM machines for mold makers.

1974

TARUS builds larger, more complex EDM Machines and Power Supplies for Mold Makers. This Dual Head EDM Machine and Power Supply System could accurately sink with two electrodes simultaneously.

1976

TARUS was the first company to create purpose-built deephole drilling (gundrilling) machines for mold makers. TARUS produces special gundrilling machines for drilling tube sheets and other models for drilling large rock boring bits. Being so well built, many operate today with retrofits and upgrades.

1979

TARUS revolutionized mold making by mass producing a modern, affordable copy milling machine called the TARUS Duplicator that was widely adopted in the industry. With retrofits and upgrades, many remain in use today.

1980

TARUS developed its own tracer and tracer control integrated into the newly developed TARUS CNC.

1980

TARUS CNC milling machines were sold to automobile mold, die, model and pattern shops throughout the Wisconsin to Toronto corridor, being the center of the automotive tooling industry in the western hemisphere. Being so well built, many operate today with retrofits and upgrades.

1980

TARUS developed a user-friendly programming utility called SPUD (Special Programming Utility for Doug), which changed everything. SPUD put a front-end code editor in the hands of TARUS employees who best understood actual machine applications. SPUD unlocked creativity and saved time unleashing features on TARUS machines that were previously impossible.

1981

TARUS introduces the TPI 8100 CNC which put us light years ahead of the competition: -High speed contour milling for mold and die makers -Special version for gun drilling machines -3D graphics with trackball user interface -3D scanning with the new TARUS rracer -Scanning of 2D drawings which when combined would produce 3D wire frame -Multiple presets, scaling, mirror, swap planes -Built in hard drives -Floppy drive storage and data transfer -Serial link data transfer

1983

TARUS develops the SENTAR which was used to create CAM tool paths and also to import, export and manipulate point and surface data from the various CAD and CAM systems. The SENTAR was equipped with various data transfer and storage media such as reel to reel tape, 8” floppies, 5.5” floppy and cassette formats. The SENTAR was very important to the Auto Industry in Metro Detroit because the tool and fixture makers used it to translate and transfer data between each other and their customers.

1984

Based on the success of TARUS CNC machines, TARUS began building computer servo-driven coordinate measuring machines (CMM) which share a GUI, allowing for seamless data exchange and user friendliness. The majority of automobile body development in North America utilized TARUS CMMs for building fixtures and body-in-white.
