High specification band saw powered

completely with electrical drives

THE MEBAe-cut band saw

operates without the need of a

hydraulic motor, instead using

electrical drives resulting in a clean

cut without compromise.

Advancements in automation and

integration of sawing techniques

within companies’ value added

chain require a continuous increase

in performance, economic systems

and customised complete solutions.

At the same time environmental factors

and energy use are more important

than ever. MEBAe-cut meets these

requirements.

All the drives on MEBAe-cut models

are powered by soft start motors,

eliminating voltage spikes. Electrical

axles are moved with high precision

and accuracy, resulting in efficient

power consumption, improving cutting

accuracy and increasing the life of the

saw blade. Electrical driven systems

have a significantly lower power

demand when compared to a hydraulic-

based system. For example, material

clamping: hydraulic clamping requires

permanent

pressure,

consuming

energy during a cutting cycle. Electric

clamps only require energy for the vice

movement (clamping and releasing),

not during the cutting cycle. At the same

time, there is no danger of leaks when

using electrical clamps.

Compared

hydraulic-based

systems, MEBAe-cut machines also

have lower maintenance and running

costs, there is no need to replace

hydraulic oils and filters, the machine/

blade performance is improved due to

increased hydraulic temperature, and

hydraulic leaks, which can be a major

concern in the maintenance of cutting

fluids and operator safety, are no longer

a problem.

Noise reduction is another positive

for the MEBAe-cut. The only noise

generated is the sound of the blade

cutting the material resulting in a much

quieter cut, which can be a major

consideration when purchasing new

equipment due to health and safety

restrictions on noise levels within the

working environment. Hydraulic-based

machines have additional noise produced

by the hydraulic pumps and motors, even

if the machine is not working.

MEBA was the first industrial

manufacturer to integrate electrical

systems into its machines with the linear

ball screw feeds. MEBAe-cut high-

performance band saw has again been

a pioneer in the industry, dispensing with

the use of hydraulic systems entirely.

The MEBAe-cut is equipped with

a newly electric material clamp. The

material is clamped in the main and in-

feed vice by a servo-controlled spindle

drive. The clamping pressure can be

adjusted individually for each application

and can be pre-selected via the

machine control. For example, thin-

walled tubes can be clamped safely.

In combination with the proven MEBA

saw feed system, the MEBA material

in-feed system and the backlash-

free guide elements, MEBAe-cut is

claimed to be unrivalled in precision

and reliability. The saw feed works

via servo-controlled lead ball screw

spindle with automatically controlled

cutting pressure and feed control.

The band saw control also includes

a two-handed operating system for

rapid vertical movement. On automatic

machines a new control system reduces

the required remainingmaterial clamping

section to 110mm. The material in-feed

system is also controlled by electric

servos and lead ball screw spindles.

The machine has automatic material

height detection and positioning of the

adjustable blade guide arm movable via

the clamping vice-jaw. These factors

ensure a high degree of flexibility.

The control panel and chip conveyer

can be located on the driven wheel or

tension wheel side of the machine. The

youngest member of the MEBA family

also boasts a compact design. Its new

CNC control is based on Windows CE

with touch-sensitive panel.

MEBAe-cut is available in three

models 400, 500 and 600, and is

available as a semi-automatic machine

or a 90° fully automatic machine. All

models are made for high productivity

and for long-term and continuous use in

single- and multiple-shift operation.

Rafter ships RT-3000 weld box and

turkshead for profiles

RAFTER Equipment Corporation has

delivered welding and straightening

equipment to a major North American

custom roll form parts producer.

The equipment included an RT-3000

high-frequency induction (HFI) five-roll

weld squeeze box and an RT-3000

double-sided turkshead straightener.

The equipment will be used for the

production of HSLA welded seam

profiles up to 3" square x 0.16" thick

for an automotive application on the

customer’s existing RLM Manufacturing

roll former. Rafter states that it was

chosen for the project because of its

reputation for providing the kind of

heavy-duty mill equipment necessary

for this application.
