Feed into the cut and back - motor-powered
Arm height adjustment - motor-powered
Central control panel - stationary
Log handling - manual
Smaller, but truly professional sawmill in all respects. Execution of main technical parts, such as the running wheels in their mounts, construction of the sawmill arm, engine and feeding systems, etc., are completely identical to those in CTR 800 series or in very powerful CTR 1000 H/40. Continuously adjustable machine feed into the cut and back and sawmill arm height adjustment. Forward/backward speed is displayed on the digital display.
The movement into and out of the cut is provided by a worm-gearbox electric motor controlled by a frequency inverter. The travel speed can be changed simply by turning the potentiometer knob on the control panel. The end positions are secured against impact by automatic deceleration and stopping. In this type of machine the central panel is stationary, placed on the beginning of a basic section. This allows convenient control of the machine from a single location.
The basic version of the machine is equipped with a powerful 5.5 kW motor. For even higher performance, for example when cutting oversized logs or even when cutting very hard materials, especially with Stellite-tipped blades a 7.5 kW motor can be used.
The massive sawmill arm is borne on adjustable hard-chromium rods (for moving up and down) which ensure absolute accuracy of sawmill arm movement and virtually unlimited service life, if the machine is lubricated regularly. The vertical movement of the arm is provided by double-sided synchronous chain transmission powered by an electric motor with worm gearbox.
The desired cutting thickness can be simply set on the touch screen with the option of setting the required kerf width. The movement of the arm, controlled by a frequency inverter with deceleration in the end positions, guarantees precise automatic setting to the desired values. Simple, intuitive operation on the colour touch screen controlled by a new-generation operating system allows a choice of four programming cutting modes. It is possible to set the repetition of a constant or variable thickness of lumber. It is also possible to choose between two methods of automatic arm exit after the cut, either to a fixed height or by the last measure.
The arm is fitted with running wheels made of high-quality grey cast iron 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 blade.
The sturdily mounted running wheel is powered through a V-belt by a professional electrical motor specially balanced against vibrations.
The tensioning wheel system moves along a sturdy cast iron dovetail slide with screws and a bar for fine-tuning, which allows highly accurate adjustment without any free travel even in long-term machine operation.
The CTR model series represents the latest trends in sawmill design, with special emphasis on maximum accuracy and long service life at minimum cost. The machines are designed in an original modular way, which allows easy replacement or adjustment of all main technical nodes and their individual parts. This significantly reduces maintenance costs in the long-term use of the machine and also reduces service times, thus reducing production downtime.
A wide range of accessories simplify and accelerate machine operation and influence its production. It is therefore possible to adapt the sawmill exactly according to the needs of the customer.

SPECIAL ACCESSORIES
-
Main motor 7.5 kW
For even higher performance, for example, when cutting oversized logs or even when cutting very hard materials, especially with Stellite-tipped blades 7.5 kW motor can be recommended.
-
Extending section 1m
Include basic rails only
-
Extending section 3 m
Include: 3x Cross beams, 2x Tilting angle bars
Variable points: 3x clamps -
Debarker
Debarker with hard metal tips is designed to remove dirt at points where the sawmill blade cuts into the log. The saw blade do not get blunt quickly. Frequent saw blade exchanges are reduced, the saw blade life, and the productivity of the machine increase.
-
Hydraulic saw blade tensioner
Operated by a hydraulic hand pump with accurate pressure indication. The hydraulic saw blade tensioner is more accurate and convenient.
-
Ammeter - blade load indicator
The ammeter scale shows the sawmill blade engine load during the cut. It is designed to simplify the selection of the feed speed; it also indicates the saw blade bluntness. A timely exchange of the saw blade increases the life-span and improves the cutting quality.
-
Electrically controlled guide bar
Adjustment of sliding guide bar of the saw blade depending on the log diameter electrically controlled from the central control desk.
-
Cant hook
Serves as help with manipulation with logs on machine frame.
-
Cam Dog Kit
Consists of a rail and a front and rear clamper/dog.
-
Log loading ramp
Provides easy and safe manipulation on machine cross beams with system of fexible stops.
-
START/STOP cooling system
Integrated in the cooling system is an electromagnetic through-flow valve, which automatically opens when the saw blade is started and closes when the saw blade is stopped. It substantially lowers the coolant consumption and saves time needed for replenishment of coolant liquid.
-
START/STOP pressure cooling system
The cooling system consists of a pressure pump in the coolant tank, flow control solenoid valve and two-way jets that spray the sawmill blade both from below and from above. Double-side cooling prevents undesirable stress in the saw band and adhesion of resin from underneath the sawmill blade and thus helps maintain stabler sawmill blade operation, more accurate cut and longer service life. Integrated in the cooling system is an electromagnetic through-flow valve, which automatically opens when the saw blade is started and closes when the saw blade is stopped. It substantially lowers the coolant consumption and saves time needed for replenishment of coolant liquid.
-
ARCTIC
Version of the machine adapted for work in extremely cold operating temperatures reaching down to - 40 °C. Machine’s switch board, control panel and digital measuring are fitted with heating elements. The heating is controlled through a thermostat. Frost-resistant lubricant. Band sawmills use frost-resistant hydraulic oil.
-
Grease Gun
For regular maintenance of the machine according to the lubrication plan. Metal grease gun for 400g tubes. Equipped with a flexible pressure hose.
-
Synthetic Grease LV 2-3
400g tube for the grease gun.
