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°

The TMJ PP 620 DGCNC is a fully automatic band saw machine with a double mitre, suitable for various sawing operations, including cross sections, different materials and frequently changed mitre cutting of sectional steel. It provides stable and high precision cutting thanks to its pre-stressed roller linear guideways, with a defined clearance, and its saw blade guidance. The saw band is adjusted obliquely by 3° for cutting sections, hollow sections, combined sections or square tubes.

The bandsaw's massive steel frame ensures a completely rigid structure, providing excellent precision and quality sawing under the best technological conditions. at an optimum price-performance ratio and to CE standard.

It has user-friendly controls, with a touch screen featuring colour graphic symbols.

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. Graphic image of the parts cut Simple program administration Network connection and router for remote diagnostics (option) USB port for data transfer, internet connection 10.4" touchscreen Feed speed selection, short cycle times Run hour counter, for an individual order and in total Material optimization Piece counter Possible semi-automatic attendance with function locking in case of the operator's failure
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 results 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, resulting in precision and clean cuts. 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 of wheel rotation - if the saw blade breaks, the wheel stops
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 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 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
OTHER	Complete electrical equipment 400 V/50 Hz Control voltage 24V DC Built-in central control panel for fully automated operation Invertor for the saw blade speed control, continuously adjustable cutting speed 10-115 m/min Electronic safety locking in case of the cover opening Automatic travel of machine vice Numerically controlled angle settings Electronic control of the saw blade creep Automatic control of cutting cycle (clamping-cutting-lifting-releasing-feeding) Hydraulic reduction of clamping pressure Rapid traverse from/to the cut, with material edge identification and automatic switching over rapid and working run Instruction manual Documentation CE Standard
