About
TARUS

For over 50 years, TARUS enables companies who develop complex shapes and form for manufactured goods achieve their goals. Our company history has been marked by a series of pioneering machine and software innovations that have propelled our growth.

TARUS is one of the few manufacturers of high-precision, large volume 5-axis CNC machines in America. Our machines are legendary for their durability and toughness. A wide number of TARUS machines are running after almost 50 years of daily use. We build machines that will last for generations.

Historically, TARUS machines were built almost completely in-house starting from raw metal billets and steel plates to developing our own CNC controls, electronics, heads & spindles, and in-house software. Even today, TARUS machines are used in the production of TARUS machines.

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 machine, directly translating into an outstanding surface finish. A stronger, more robust structure also means higher performance. TARUS machines can handle a larger milling head, more powerful components, and faster speeds.

In mold and die, our machines achieve the highest level of performance and automation. TARUS 5-axis mills now feature the best available CNC from Heidenhain and Siemens, with German, Swiss or Italian supplied milling heads and spindles.

In aerospace, TARUS 5-axis mills are used for the manufacture of layup tools for composite components, large drilling and assembly fixtures, and milling aluminum aerostructure components.

A pioneer in gun drilling, TARUS machines are used across industries including molds for plastic, diecast dies, and tube sheets for heat exchangers, process equipment and power generation.

In automotive, TARUS machines are utilized throughout the entire process of automobile design, body development, tooling, and manufactured component inspection.

TARUS invented the claymill and remains the preeminent global leader with cutting-edge clay milling machines and comprehensive car design studio solutions. Roughly half of the passenger vehicles driving on North American roads today got their final shape and design on a TARUS claymill. TARUS currently builds the largest variety of claymills with the greatest performance, capability, and reliability available. Our comprehensive suite of car design studio solutions and accessories will complement the most demanding requirements.

With a history of innovation, TARUS CMM are widely used by automotive, aerospace tooling & gauge manufacturers. In addition to the TARUS CMM software package, we now also offer open-source digital CMM controls including Renishaw and Pantec.

After being frustrated with numerous ERP platforms that didn't fit the needs of complex manufacturing, TARUS spent millions of dollars developing its own ERP platform - the first ERP built by Manufacturers for Manufacturers. TPI Shop ERP is the backbone of TARUS operations and profitability and enjoys growing adoption at various companies.

The TARUS service department services TARUS machines as well as many other CNC machines. Our technicians and engineers have performed installations, upgrades, retrofits, preventive maintenance, calibrations, and repair throughout North America, Europe, East Asia, India, South America, and Australia.

    1980

    Originally, TARUS software developers would write code in Assembler in consultation with application engineers, which was an arduous process. Software developers usually didn't fully understand machine applications, so a lot was squandered in this ineffective and time-consuming process. 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.
