Modular toolholding EWS introduces Varia Next system for CNC lathes

Modular adapters allow lathe operators to exchange preset cutting tools while leaving the base toolholder in the turret. Launched at AMB, EWS Varia Next extends this approach across the manufacturer’s range, with claimed changeover times of around 20 seconds.

At the recent AMB trade fair in Stuttgart, German toolholder manufacturer EWS Tool Technologies introduced modularity into its standard product line by unveiling EWS.Varia Next. In the UK and Ireland, the company’s products are sold by sole agent Nydaloxe Precision.

While the EWS philosophy of retaining permanent base toolholding units in a lathe turret and exchanging modular adapters with clamped cutting tools has been established practice for more than a decade, the exhibition served as the launchpad for a unified ecosystem across the company’s entire range of lathe toolholders.

With the Varia system, operators do not have to detach the complete tool holder. Instead, they complete an easy, rapid, one-handed changeover at the interface of a preset tool in its adapter and a base unit, a procedure that takes about twenty seconds, representing a time saving of up to 90 percent.

The show launch restructured the modular range into three generations centred around a single base unit. It utilises a combination of taper-and-face contact offering ± 0.002 mm repeatability together with a mechanical mechanism that pushes an adapter out of a base unit when the clamping screw is loosened. This breaks the tight taper seal, preventing lock-up from the presence of coolant or chips, or due to thermal expansion, and facilitating adapter removal.

For high-speed and high-torque machining operations, the new VXP high-performance milling series also made its debut at the exhibition. The design features a patented Double Cone Flex damping interface, whereby an extra cone with built-in compliance is added at the rear of the base unit. It enlarges the distance between the adapter’s front and rear supports, improving rigidity and reducing vibration.

The milling toolholders are complemented by the compact VXT series for static turning, which also features Double-Cone Flex in its design. The system employs an external clamping ring to leave the inner bore free for inserting deep boring bars, while maintaining a short overhang near the turret.

Completing the lineup is the original VX series for standard operations, which ensures that adapters having a legacy profile remain backwards-compatible with the new VXP and VXT base toolholding units.

The updated 2026 generation lineup supports over 60 adapter profiles, including collet chucks, shrink-fit holders, hydraulic chucks and specialised interfaces for specific makes of CNC lathe. All are equipped with integrated diaphragm seals capable of handling internal coolant pressures up to 100 bar.

The full EWS.Varia Next system is available with turnkey starter kits that include essential mounting blocks, torque wrenches and storage options to enable seamless adoption.
