Technology Brings Electric Cars to Life

Rimac headquarter is located on the outskirts of Zagreb, Croatia, and is very vertically integrated, with many components produced on-site. They are an established electric hypercar manufacturer, and a leader in high-performance electric vehicle technology, supplying their key electrification components to many partners in the industry.

The Rimac C_Two accelerates from 0 to 100 km/h in 1.97 seconds (0 to 60 mph in 1.85 seconds).

The C_Two features a full-carbon monocoque, an integrated lithium nickel manganese battery pack with a capacity of 120 kWh and an impressive output of 1.4 MW, and additional structural components made of aluminum and carbon fiber.

Four electric motors – one for each wheel – offer both all-wheel drive and unparalleled dynamic control. The oil-cooled dual motors deliver immediate propulsion, energy conversion efficiency of over 97 percent, and a nearly unlimited and maintenance-free service life. While two transmissions produce propulsion at the front wheels, another two – one for each rear wheel – enable the C_Two to unleash an impressive torque of 2,300 Nm. These performance data of 1,914 hp translate into an acceleration that propels the C_Two hypercar to 412 km/h. The C_Two is a 100% electrically powered GT hypercar that’s just as breathtaking as it is tailored and user-friendly.

Innovative Products Require Innovative Production Methods
Aluminum, copper, and NECURON materials, in particular, are machined during the manufacturing process at Rimac Automobili. Production with conventional clamping tools reached its limits around two years ago. The required manufacturing tolerances and surface qualities could no longer be achieved. The concentricity (T.I.R.) of the clamping tools used was insufficient, just like the low clamping force, which more often than not resulted in tool pullout.

powRgrip Increases Quality and Productivity
For years, Rimac Automobili has maintained a good partnership with REGO-FIX sales partner PFEIFER-TTI d.o.o. in Sveta Nedelja, Croatia. The PFEIFFER company provides Rimac Automobili with technical support when it comes to machining. It soon became clear that, to increase productivity and manufacturing quality and reduce the defect rate, the existing shrink-fit and ER toolholders needed to be replaced with state-of-the-art tool clamping. The PFEIFER company recommended testing the powRgrip system. Like the trust in the PFEIFER company and its technical advice, the recommendations for the powRgrip system were so convincing that the powRgrip tool clamping system was immediately introduced without extensive testing.

Rimac Automobili clearly promotes growth with its products, and powRgrip enables this increase in quality and productivity in production.

powRgrip – Simple and Safe
Rimac Automobili now uses PG 6, 15, and 25 powRgrip toolholders on tool machines with HSK-A 63, HSK-F 63, and SK40 spindle interfaces. The PGU 9500 clamping unit won over Dalibor Kalazic – Metal Manufacturing Coordinator at Rimac Automobili – thanks to its safe and simple use. The hydraulic PGU 9500 clamping unit safely and simply presses tools into the toolholders without heat using the corresponding powRgrip collets and applying up to 9 metric tons of pressure – and this takes less than 8 seconds.

The toolholders can now be used.

“Perfect precision, its reproducibility, safety, and simple use make production more effective and efficient,” says Dalibor Kalazic, briefly explaining why the REGO-FIX powRgrip clamping system is indispensable for him and Rimac.

Infokasten Rego-fix
As an international family-owned and operated company with more than 200 employees in its second generation, REGO-FIX produces and sells high-precision tool clamping systems. The company based in Tenniken, Switzerland, is now one of the leading manufacturers of tool clamping systems and enjoys an outstanding reputation the world over in the metalworking industry. Thanks to its global network of sales partners with locations in Switzerland, the US, and Asia, REGO-FIX is optimally positioned and represented throughout the world. With its pioneering product inventions, REGO-FIX has developed from a small company into a global solutions provider for tool clamping systems. Each and every product is developed with a focus on increasing productivity and produced in line with Swiss quality standards. REGO-FIX products are most commonly used in the construction of vehicles, aircraft, molds, and machinery, as well as in medical technology and the production of clocks and watches.

Infokasten powRgrip
powRgrip can clamp all shank materials, whether solid carbide or HSS, as well as all standard shank shapes, whether cylindrical, Weldon, or Whistle Notch. Shank diameters from 0.2 to 25.4 mm for milling, reaming, drilling, lathing, and tapping can be used with the extensive range of PG collets. MQL, peripheral, and internal cooling is possible depending on the collet, with powRgrip colletholders available for many spindle interfaces such as REGO-FIX CAPTO, BT, BT+, SK, SK+, HSK, CAT, and CAT+ interfaces as well as cylindrical powRgrip colletholders.
