What are our NTR metal spinning machine models?

The perfect balance between industrial power and ease of programming.

The NTR is a CNC-automated metal forming lathe: metal spinning, shear forming, and finishing operations in a single machine.

It is designed to manufacture rotationally symmetric metal parts from discs (blanks), tubes, cones, or simple preforms, combining industrial productivity with intuitive graphical programming to speed up setup and improve repeatability.

DENN machines can be integrated into automated production lines.

Benefits of the NTR models:

3 Processes in 1: metal spinning, shear forming, and auxiliary machining/finishing operations.
Fast and Visual Programming: Integrated graphical system (DENN CAD-CAM) to create work cycles without advanced CNC knowledge. Easy integration of intelligent (AI-based) solutions.
More Productive Hours: Program while the machine is running in production.
Fleet-Wide Repeatability: Transfer part programs between machines and keep consistent results across all equipment.

What are our TES metal spinning machine models?

CNC spinning and shear forming for demanding, versatile production.

The TES is a CNC spinning lathe designed to manufacture parts through spinning, shear forming, and auxiliary operations.

It produces rotationally symmetric metal parts from discs (blanks), tubes, cones, or simple preforms, combining industrial productivity with graphical programming to speed up setup and improve repeatability.

DENN machines can be integrated into automated production lines.

Benefits of the TES models:

Robust design for demanding operations: Rigid machine bed and assembly designed for heavy-duty production.
Fast programming for series production: Simple and efficient programming using the Record function.
Manufacturing versatility: Spinning and shear forming for a wide range of parts.
Stable industrial output: Consistent results across production cycles.
