FULLY AUTOMATIC CNC-CONTROLLED MACHINE FOR SIDE GRINDING WITH DOUBLE WHEEL ON CARBIDE-TIPPED CIRCULAR SAW BLADES FROM ø100 TO ø850 MM. WITH 5 CNC AXISHIGHLIGHTSEASY TO USE: Control panel with 10,1" color LCD screen and on-screen guided instructionsLOW MAINTENANCE: Hydraulic free for trouble free maintenance5 CNC axes for automatic work programmable from the control panelCompletely automatic sides grinding of circular saw blades with carbide tipVery compact machine with a wide range of disc diameters: from 100 to 850 mm.ELITE GBT 851. THE CONCEPT.The ELITE model GBT 851 is our CNC automatic side grinding machine for circular saws with tungsten carbide teeth from ø100 to ø850 mm. diameter. It is similar to the GBT 850 but with 1 more CNC axes that allow the machine to befullyautomatic in each adjustment of the tooth geometry, counting a total of 5 CNC axes.This version is equipped with a double grinding wheel and its CNC operation with a 10.1" color LCD screen allows precise and fast sharpening of the tooth flanks to manufacture carbide circular saws or repair recently welded teeth when replacing teeth.It is designed to be automatic without unnecessary additional costs. No complicated extra that can easily break or are expensive to repair.ELITE GBT 851. HOW IT WORKSVery simple programming through a guided menu or entering grinding data.Fully automatic operation using 5 CNC axes:A: Tooth pitchX: Sharpening pathY1: Left tangential angle of wheel No. 1Y2: Right tangential angle of wheel No. 2Z: Lateral angleFully enclosed cabin for silent operation with a very fast door opening system that guarantees quick mounting of the saw blade and access door for maintenance.Saw diameter from 100 to 850 mm, for grinding the flanks of scoring discs or portable machines as well as sawmill saws.Tooth pitch programmable from the control panel.Easy to use control panelThe control panel incorporates a color touch screen. This screen has been designed with a fast and easy-to-use interface that makes it very user-friendly. It is also possible to create or edit a program while the machines is running.The machine includes a LED cabin light as standard.Tooth pitch programmable through the software on the control panel.The color touch screen control panel allows creation or editing of a program while the machine is working on another program. Among the programmable values are:Tooth angle programming: The grinding wheel axis will automatically move to the value entered in the program.Sharpening pathSharpening loadSharpening speedTooth pitchIndexing movement of the tooth feeding pawlNumber of teethBroken teethGrinding wheel rotation speed variable from 5.000 to 9.000 RPMThe direct grinding wheel spindles are adjustable between 5,000 to 9,000 RPM for optimal sharpening quality with minimal grinding wheel wear.The spindles are driven by a frequency inverter, so you can adjust the grinding wheel speed to the optimal value as well as reduce energy consumption.Integrated refrigeration equipmentMachine operates with water-soluble coolant or grinding oil for better sharpening quality and longer grinding wheel life.Integrated coolant system with 220-liter tank and removable grates for easy cleaning.Easy access and maintenanceAt the back of the machine we find the electrical panel at the bottom and the mechanical system at the top, both protected by their corresponding easy-access panel, which also reduces the total space needed for the machine.ELITE GBT 851.
