Belt and brush sanding machine VEN BRUSH HYBRID

Year of construction 2011 GLOTTING BRUSHING MACHINE VEN BRUSH HYBRID The machine is used for rough sawn wood as well as intermediate sanding of smooth and profiled parts, consisting of: 2 belt grinding assemblies Grinding assembly 1: cross-band assembly with - pressure flexible belt with felt and graphite for long service life - ISD link pressure beam system with 22 mm workpiece recognition and 44 mm workpiece width - workpiece-controlled grinding belt blowout + ISD link pressure beam system (grinding assembly 1) As ISA but additionally with - separate adjustable pressure for the edge area (higher or lower) - optionally only on the outer edge or outer and inner edges - longitudinal and transverse edges or only longitudinal edges, optimal air guidance to meet TRK values, dust-tested Grinding assembly 2: combination assembly with - grooved rubber contact roller Ø 130 mm, 60 Shore - computer-controlled delivery of the contact roller - computer-controlled grit compensation - ISA link pressure beam system with 22 mm workpiece recognition and 22 mm workpiece width. - counter-rotation - workpiece-controlled oscillating belt blowout + ISA link pressure beam system (grinding assembly 2) - piece in longitudinal and transverse direction movable - point-like contact of the workpiece - universal pad for all grinding tasks - tolerance compensation +/- 1 mm ISA link pressure system: General, aggregates: Grinding aggregates designed for one- or two-shift operation. - belt discharge switch on the wide belts coupled with oscillation - automatic grinding belt length compensation - belt scanning optically contactless and self-cleaning on belt change side - setting of oscillation on belt change side - wear-free direct current braking - suction hoods with optimal air guidance to meet TRK values, ISA/ISD-Control - high-resolution workpiece recognition in 22 mm grid - free feeding of complex part shapes - multiple loading with small lateral spacing - grinding intensity on all edges individually adjustable - grinding pressure adjustable via program - path control of the link pressure beams (feed-dependent) - all settings via operator terminal (program-controlled) Control All settings required for different grinding tasks can be made directly via the touch operator terminal and saved. Thus all achieved grinding results are reproducible at any time. Grinding assembly 3: 1 cross-brush assembly consisting of four counter-rotating brush segments for intensive smoothing of the crosswise to the conveyor direction running workpiece profiles. Executed as a replaceable brushing module. Grinding speed infinitely adjustable. Grinding assemblies 4+5: 2 rotating brush assemblies The brushes are equipped with a quick-change system, so brushes with different pile can be used within a few minutes. The brush speed is changed via a frequency converter and is shown on a display. The brush height for each brush can be set individually. Machine frame Heavy steel welded construction to accommodate 2 grinding assemblies. Electrical control cabinet integrated in the frame. - constant inlet height of 900 mm - operating and belt change side on the right - heavy height adjustment via lifting spindle drive - transport table with transport belt in vacuum version and 1 vacuum fan 5.5 kW - safety devices in accordance with CE norm - electrical equipment according to VDE - doors on both sides of the machine, on the belt change side with safety switches and sight window for monitoring grinding- belt oscillation Control terminal “SIEMENS MP 277 - graphical operator guidance over 10.5” color display - program memory with 300 program memory locations - setting of all parameters via program 1 electrical control cabinet With all required switching and protection elements, motor protection switches, indicator lamps and main switch. The control cabinet contains all required contacts to interlock both the offered machine as well as external machines. The control cabinet is integrated into the machine.
