Feed into the cut and back – motor-powered
Arm height adjustment – manual
Control panel – on a mobile bridge
Log handling – manual
The bigger and stronger version of the popular CTR 550 allows for processing of logs up to 75 cm in diameter. It also uses a bimetallic metal-cutting saw bands, but it is one size bigger. While the size of the bimetallic saw band in CTR 550 is 27 x 0.9 mm, the size of the band in CTR 750 is 34 x 1.1 mm which, combined with a powerful 5.5 kW engine can deal with logs of large diameters.
Unlike CTR 750, this model is equipped with mechanical feed into the cut and back with continuous speed control. That greatly increases comfort of the operator and the overall productivity. The feed is driven by an electric motor with worm gearbox controlled by a frequency converter. You can change the speed of travel simply by turning the potentiometer on the control panel. End positions are secured against impact by means of automatic deceleration and stopping.
The control panel is placed on a mobile bridge of the saw band arm. Thanks to that the operator has closer access to the workpiece when cutting. Height is adjusted using a hand crank with adjustable scale.
Use of a bimetallic saw band which is normally used in metal band saws brings following advantages:
- very simple operation
- single saw band cuts all types of wood without tooth adjustment (sharpening, tooth setting)
- elimination of tedious, technically challenging sharpening and setting of teeth
- you can immediately start cutting wood in professional quality without any necessary experience
- bimetallic saw band easily cuts metal materials in the log such as nails, shrapnel or bullets
- professional three-side hardmetal saw band guidance in guiding heads and robust support of all rotary parts ensure high cutting accuracy and long service life of the saw band
- maximum accuracy, like in professional machines
- no need to purchase tooth sharpener and tooth setting machine
- easy accessibility and low cost of bimetallic saw bands
Powerful 5.5 kW engine ensures full power during fully professional cutting, cutting of high-quality round timber or when cutting very hard materials. Instead of bimetallic metal-cutting band sized 34 x 1.1 mm you can use a special bimetallic wood-cutting band sized 35 x 0.9 mm which (same as the bimetallic metal-cutting band) does not require sharpening and setting of teeth. You can also fit your machine with standard saw-cutting bands (35 x 0.9 mm) identical to those used in higher professional models CTR 710, 800 and 950. Larger teeth in these saw bands allow for increase of productivity when cutting large diameter logs. However, in the above mentioned saw bands it is necessary to sharpen and set the teeth regularly.
The arm is fitted with large aluminium running wheels with accurate balancing against vibrations. The wheel has a groove along its circumference. The groove holds a replaceable rubber-textile belt which creates an optimum contact area between the wheel and the saw band.
The sturdily mounted running wheel is powered through a wedge belt by a professional electrical motor speciallybalanced against vibrations.
The tensioning wheel system moves within a solid cast iron guiding, which ensures long-term service life and setting accuracy even in long-term machine operation.
CTR series present the latest trends in construction of log saw bands with a special emphasis on maximum accuracy and long-term service life of the machine while ensuring minimum costs. The machines are designed in an original modular execution which allows easy replacement or adjustment of all main technical sections and their individual parts. This in the long-term perspective reduces the maintenance costs and service times and therefore production stoppages as well.
