DOUBLE-WHEEL SHARPENING MACHINE FOR CARBIDE CIRCULAR SAWSHIGHLIGHTSDouble grinding wheel for sharpening the front and back in a single preparationDouble grinding wheel for face + top grinding in one preparationEASY TO USE: control panel with 10" color screen with guided instructionsLOW MAINTENANCE: hydraulic free for trouble free maintenance5 CNC axes for automatic workVery compact machine with a wide range of disc diameters: from 100 to 850 mm.ELITE AVB 850. THE CONCEPT.The ELITE model AVB 850 is our new and fastest sharpening machine for the top and the face of all common tooth geometries in circular saw blades with carbide tip for circular blades diameters from ø100 to 850 mm.Total grinding time (face + top): just 12 minutes and 33 seconds.The double-grinding wheel system allows for complete sharpening of the face and back in a single setup: when the machine finishes sharpening the face, it automatically adjusts to sharpen the back, or when it finishes sharpening the back, it automatically adjusts to sharpen the face. Remove the finished saw from the machine!Face + top grinding in a single setup: ELITE AVB 850 modelOne-pass external sharpening for tooth types:Flat, inclined, alternating, alternating with bevel, pointed, trapezoid, trapezoid-flat, pointed-flat, alternating-flat, trapezoid-trapezoid.With 5 CNC axes for complete machining of all common tooth geometries in one cycle, particularly short strokes ensure fast sharpening operation.Fully enclosed cabin for silent operation with a very fast door opening system that guarantees quick placement of the saw blade and access door for maintenance.TOOTH TOP SHARPENING PROGRAMMINGThe touchscreen for quick and easy programming.The tooth shape can be selected at the bottom of the screen. The data required for tooth sharpening appears in the center of the screen when the tooth type is selected.You can choose the sharpening order: first sharpen the back of the tooth, then the face; or in reverse order: first the face and then the back.The machine will automatically sharpen the entire saw teeth (top + face) to obtain a completely finished saw.STANDARD TOOTH TOP SHAPESTOOTH FACE SHARPENING PROGRAMMINGThe face sharpening programming screen allows you to select, among other things, the type of grinding wheel sharpening: Start sharpening, move the wheel away, and exit without sharpening. Or start sharpening and exit polishing with the wheel.You can also select the direction of rotation of the grinding wheel: left, right, or reverse direction for each tooth. You can also select the speed of rotation of the grinding wheel.The tooth shapes allowed are varied: flat tooth, side angle, angle on both sides, or a combination.You can choose the sharpening order: first sharpen the back of the tooth and then the face; or in reverse order: first the face and then the back.The machine will automatically sharpen the entire saw teeth (top + face) to obtain a completely finished saw.Grinding the shear angleSTANDARD TOOTH FACE SHAPESBROKEN TEETH OR NEW TEETHYou can easily add and edit broken teeth or new teeth. This feature can then be activated or deactivated without having to change the entered values. Very useful, for example, for skipping broken teeth when sharpening the face, but deactivating this option when sharpening the back.The machine is equipped as standard with the multi-pass sharpening program forretoothing discs with new teeth.VARIABLE PITCH: Precision and flexibility for complex geometriesThe Tooth Pitch mode on the ELITE AVB 850 allows for highly precise programming and adjustment of the distance between teeth, accommodating a wide range of pitches including variable pitch and special tooth configurations. This system ensures perfect synchronization between the saw blade’s feed motion and the grinding cycle, delivering consistent sharpening quality regardless of tooth design.With its intuitive interface, the operator can manually enter the desired pitch or select from pre-set parameters. The machine automatically detects each tooth position and adjusts the feed smoothly and accurately, reducing setup times and eliminating indexing errors.This mode is especially valuable for saws with complex geometries or mixed production runs that require frequent pitch changes. Its precision improves tool life and significantly reduces grinding wheel wear.ELITE AVB 850. HOW IT WORKSAutomatic operation using 5 CNC axes:A: Tooth pitchB: Tooth cutting angleC: Lateral angle of the top of the toothX: Sharpening loadZ: Sharpening pathEasy to use control panelThe 10,1" 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 wheel axis is automatically positioned to the value entered in the program• Tooth geometry• Sharpening path• Sharpening charge• Sharpening speed• Tooth pitch• Tooth advance claw feed rate• Number of teeth• Broken teethUp to 10 teeth/minute when grinding discs with flat trapezoid teethUp to 10 teeth/minute for the most typical tooth geometry: flat trapezoid. All movements have been optimized to reduce downtime. Making the AVB 850 our fastest grinder, allowing a 96-tooth flat trapezoid disc to be ground in less than 10 minutes.Variable wheel rotation speed from 2,500 to 5,000 RPMVariable wheel rotation speed from 2,500 to 5,000 RPM. Includes a variable frequency drive as a standard feature, allowing you to adjust the wheel speed to the optimal value required and reduce energy consumption.Integrated cooling systemMachine 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 AVB 850.
