Electric horizontal log band saw CTR 550 E

Electric horizontal log band saw CTR 550 E

Electric horizontal log band saw CTR 550 E is the smallest machine in the offer. It is designed primarily for cutting smaller volumes of lumber. Ideal solution for fa- mily farms, joiners’ workshops or small sawmills. Unlike CTR 550, 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 pro- ductivity. 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.

First machine of its type in the world that uses bimetallic saw band which is by default used in metal band saws. That brings the following benefits:

• 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

Total power input of the Log band saw CTR 550 E of 4,2 kW guarantees low operating costs and easy connection to mains. You may also use a special 35 x 0.9 mm bimetallic saw band instead of the 27 x 0.9 mm bimetallic saw band. Similarly to the metal- cutting bimetallic saw band it doesn’t require any sharpening or tooth setting. You can also fit your machine with stan- dard saw-cutting bands (35 x 0.9 mm) identical to those used in higher professional models CTR 710, 800 and 950. Lar- ger 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 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 electric motor specially balan- ced 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.

A precise, three-sided hard-metal guidance guides the saw band in the cut. This system can be fully adjusted in all directions and it ensures optimum saw band guidance.

Gravity cooling and lubrication of the band with an adjustable outlet before the cut ensure that the saw band is in optimum condition during cutting.

Stable running sections are sufficiently dimensioned for maximum diameters of logs as well. They were designed reflecting the practice, therefore designed to cope with very hard operating conditions. Cut length is virtually unlimited in all types of machines, it only depends on the length of running gear installed. They are fitted with retractable angles and hand-operated log clamps. The basic version of the machine includes 3 workpiece clamps and 3 retractable angles.

In order to minimize the transport costs the running gear sections are supplied dismantled.

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.
