Mobile bending systems JUTEC Biegesysteme GmbH develops and manufactures tube bending systems. The standard of Jutec bending systems, their controls and machine construction is a result of the company’s long-standing experience and continuous development. has received a new ma i n t e n a n c e - f r e e three-phase motor

that is driven by a frequency converter and allows power supply of over 230V. The motor can be smoothly adjusted in speed, and the bending tool can drive backwards with higher speed, which leads to shorter cycle times. The repetition accuracy is increased, and the tool can be set to 0.5°. The model 6000 mobile bending sys- tems can now bend pipes more precisely to an outside diameter of 60mm. The frequency con- verter technology en- ables the use of the

The company’s range of mandrel bending machines includes bending system solutions up to D = 90mm, with simple and convenient operation via a solid user interface, and USB ports for data exchange. The systems offer efficient and convenient handling, and bending radii up to 1.5xD. For higher output and low downtimes, Jutec has developed ‘Power Hydraulics’, which helps reduce the cycle time per sheet. Using the proven rotation stopper, which is optionally available, or the quick-acting chuck, the production volume of serial parts can be significantly increased. Dimensional accuracy of serial products is guaranteed for both standard parts as well as single parts. The model 3000 mobile bending machine for pipe diameters up to 35mm

can be stored. The ramp function (slow acceleration and deceleration of the bending axis) increases the precision, and the bending quality in the starting and end regions is improved. All models are available from stock at short notice.

machine with 230V with the model 6000S for pipes up to 48mm (the power supply of 400V for pipes up to 60mm in the model 6000D remains unchanged). In comparison with the previous model with 400V power supply, the power consumption of the three-phase drive is reduced by around 30 per cent.

Polishing and grinding GRIND Master offers automatic centreless belt grinding and finishing machines for belt grinding, bright finishing and satin finishing of round tubes and pipes. A wide range of consumables, including abrasive belts, flap wheels, non-woven wheels, sisal and cotton buffs, can be used in predetermined sequence for achieving the desired finish.

created on this machine. The process of belt grinding removes surface defects at higher speeds, compared to conventional wheel grinding. VSM ceramic belts for roughing and compact grain belts for finishing give consistent finishing results. The machine can achieve finishes up to 0.12 Ra and h9 tolerance.

The machines have easy settings to ensure quick changeover from one job size to another. The floating belt grinding heads are designed to take care of bend and ovality in tubes. Up to ten heads are offered. An automatic loader/unloader is available as an option, and machines are designed for dry grinding as well as wet finishing.

Tube up to 220mm diameter can be finished, and the machine can be supplied with an auto tube size setting, which requires only two to five minutes for setting the machine. Grind Master also offers a six-head belt grinding and polishing machine for round bars. From the raw black bar, a ground and finished bright bar can be
