KRRASS Advanced Electric NC Hydraulic Tube Bender

The hydraulic tube benders of the ECO-NC series are easy to operate, robustly constructed and achieve excellent bending results. Entering new bending programs is intuitive, thanks to an industrial touch controller and the accurate and user-friendly KRRASS 2D software. The NC program controls the bend angle (Y axis) and rotation (Z axis). The distance between elbows (X-axis) is configured using easily adjustable and precise mechanical stops.

Simple, durable and with excellent bending results.

Work area can be customized and all types of tool clamping can be installed.

Supporting hydraulic drive.

General Information

The basic movements – bending angle and rotation of the pipe – are fully electric to ensure exact repeatability. A powerful hydraulic group drives the supporting bending movements. All activities are electronically controlled. These properties make these machines versatile and suitable for high-quality bending work in small and medium-sized series.

Evolutionary Design

Our hydraulic tube benders are the result of decades of experience in the world of bending. The user experience of thousands of customers worldwide has resulted in unique application-oriented solutions for these machines. We facilitate human-machine “communication” using visual status indicators and warning messages.

Advantage:

The ECO series of semi-automatic fixed-radius hydraulic tube benders are versatile, powerful, and easy to program and operate. They are intended for sectors that choose versatility and bending quality in speed and productivity. Sectors include urban furniture, agriculture, prototyping, chemical industry, and ship repair.
