TMJ PP 620 DGCNC 

BAND SAW WITH LINEAR GUIDEWAY 
FULLY AUTOMATIC BAND SAW MACHINE WITH DOUBLE-COLUMN GUIDE, DOUBLE MITRE AND AUTOMATIC CONTINUOUS SETTING OF ANGLE AT 90°, +/- 45°, +60° 
 
This fully automatic band saw machine with double mitre is suitable for versatile use at various cross sections, materials and frequently changed mitring for cutting of sectional steel. Stable and precision cutting due to pre-stressed roller linear guideways with a defined clearance. Precision cutting due to saw blade guidance fitted with carbide and mitre cutting technique; saw band is adjusted obliquely by 3° for cutting of sections, hollow sections, combined sections or square tubes. 
 
Massive steel execution create the frame that guarantees a completely rigid structure and represents an extraordinarily important prerequisite for precision and quality of cutting under the best technological conditions. Ergonomic maturity and optimum price-performance ratio. 
 
Simple central attendance and user-friendly control with a touch screen and colour graphic symbols. Design execution of the machine complies with CE standard. 
BASIC EQUIPMENT 
PP 620 DGCNC 
CNC CONTROL 
Selection of programs by means of B+R (Bernecker and Reiner) colour touch screen. 
Simple creation of programs and administration of up to 99 cutting programs with different lengths, a large number of pieces and angles, selection of angles from 90°, +/- 45°, +60°. The operator enters the cutting task on the screen window by means of a graphic image of the cut. Errors in entering the task are minimized, a simple and safe creation of production orders from various operators is ensured. Only good parts are programmed, waste is calculated automatically by the control. All machine functions can be centrally controlled and checked from the control panel.

SAW ARM 
Saw arm consisting of a solid steel structure that travels on two pre-stressed roller linear guideways with a limited clearance. 
Hydraulically controlled lifting of the saw arm with dynamic regulation of cutting pressure by means of a double-sided scanning of the rear saw blade side. 
Infinitely variable hydraulic regulation of cutting pressure and feeding speed. 
Permanent control of cutting force at the rear side of the saw band results in optimum proportions for every cutting operation, i. e. constant pressure at solid material and constant feed at sections. 
Material identification and fast run reduction. 
Unique band saw with double mitre, where the double-sided mitre can be set by a mere swivelling of the saw arm. Material clamping remains without change. 
The saw blade is set to a contact surface of material in inclination of 3°, this result in optimum teeth mesh, better cutting performance, a higher quality of the cut and a slow entry and exit of the saw band at various material cross sections. 
Movable guide arm of the saw blade is adjusted automatically to width of material - optimum cutting results. 
SAW BLADE 
Saw blade - Reversible rollers -Carbide guideways - Mechanically pre-stressed guideways 
Movable guide arm of the saw blade is adjusted automatically to width of material, this result in precision and clean cut. 
Smooth run of the saw blade is ensured by two heavily-dimensioned guideways with guide rollers and carbide blocks. 
If saw blade overloading occurs, the saw blade slows its activity and the cutting process continues further. 
Sensor monitoring tensioning wheel rotation in case of breaking of saw blade wheel stops and sensor signalling breaking of saw blade let machine to stop. 
SAW BLADE TENSIONING 
Hydraulic tensioning of the saw blade with possible manual pre-stressing and mechanical protection that guarantees a proper tensioning even in case of the system pressure fluctuation. 
CLEANING BRUSHES 
Motor-driven cleaning brushes located across the saw blade ensure chip removal from the saw band and increase its service life. 
MACHINE STAND 
Built-in hydraulic aggregate with double pump and output from 8 + 2.1 dm3/min 
Coolant tank, capacity approx. 100 litres 
Chip tray 
MAIN MOTOR 
Continuous, frequency-regulated, AC, 4 kW - Drive with electronic control of minimum speed and saw blade breakage 
ANGLE SETTING 
Setting of the saw arm angle is carried out continuously by means of a frequency-regulated motor with a gearbox, chain pinion and chain. 
At arm turning is sufferable tolerance for turning point 1° +/- 0,15° 
Position can be read by means of a magnetic strip and clamping is made hydraulically. 
MATERIAL FEEDING SYSTEM 
Feeding length is 1400 mm per each stroke and can be repeated arbitrarily. 
Slide mounted feed vice, automatic adjustment at materials with irregular surface. 
Positioning output member with a frequency-regulated motor and gearbox, precision measuring toothed rod and absolute speed scanner. 
Hardened grooved clamping jaws. 
The feeder is guided on two linear ball guideways. 
Identification of the section front edge and the rod end by means of an optical barrier. 
Minimum waste length due to optimum contour of the feeder also when mitring. 
Tolerance in material feeding length +/- 0,2 mm/500 mm 
Tolerance in cutting plumb +/- 0,1 mm/ 100 mm
