TMJ PP 302 GCNC
BAND SAW WITH COLUMN GUIDES
The TMJ PP 302 GCNC is a fully automatic, electrohydraulic, CNC band saw machine for metal cutting, dedicated to straight cuts, with the ability to mitre cut from 90° to 60° right in automatic mode. The bandsaw's extremely rigid machine stand and saw arm strength ensure a long life and exceptional accuracy. Its two-column, solid steel construction forms a closed frame, ensuring perfect rigidity.
The bandsaw is controlled by means of a microprocessor control system with a screen and keyboard to program the required functions. The machine stops when the number of functions set is achieved, when the saw blade breaks, and when there is missing material. The bandsaw is equipped with electronic feeding of material up to 600m in length by means of a ball screw (arbitrarily repeatable) and with step feeding from the rear position with accuracy ± 0,1 mm.

SAW ARM |
Travels up and down by means of hydraulic cylinder; the piston rod is formed by chrome-plated guiding column. Upper position can be adjusted based on the height of material to be cut. 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. Angle of cut can be set continuously without a change in clamping of material. |
SAW BLADE |
Smooth run of the saw blade is ensured by two heavily-dimensioned guideways with guide rollers and carbide blocks. Movable guide arm of the saw blade can be adjusted to width of material, resulting in precision and a clean cut. Proper tensioning of the saw blade is regulated by adjusting spindle and Belleville springs. |
CONTROL OF RUN |
Feeding speed of the saw arm towards the material is realised through a throttle valve. Saw blade pressure into the cut is controlled by an automatic valve (derived from cutting resistance), which regulates feeding speed into cut by solid material to conform to cutting conditions set and to prevent overloading the of saw blade. In case of saw blade breakage, the machine stops automatically. |
CONTROL SYSTEM |
Control system B+R. All functions of the band saw are controlled by means of virtual buttons on the touchscreen of the control system, which are marked with comprehensive symbols displayed on a large graphic screen with information on settings of technological and operating parameters. Possibility to enter different programs, where up to 100 different lengths, number of pieces and cutting speed for each program can be set. Possibility to choose language version, metric or inch units. System identifies failures and saves them into memory along with respective date and time. Electronic feeding of material up to length of 600 mm per each stroke can be repeated arbitrarily with step feeding from the rear position of accuracy ± 0,1 mm. |
