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.

The double grinding wheel system allows complete sharpening of the face and back in a single preparation: when the machine finishes sharpening the face it adjusts to sharpen the back automatically, or when it finishes sharpening the back it adjusts to sharpen the back. expensive.

One-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.

It uses the famous peripheral grinding wheel system to achieve a saw blade with a perfect edge.

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.

ELITE AVB 850. HOW IT WORKS

Automatic operation using 5 CNC axes:
A: Tooth pitch
B: Tooth cutting angle
C: Lateral angle of the top of the tooth
X: Sharpening load
Z: Sharpening path

Easy to use control panel

Panel%20control

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 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 teeth

Grinding wheel rotation speed variable from 2.500 to 5.000 RPM

Our machines include the variable frequency drive as a standard feature, so you can adjust grinding wheel speed at the optimal value and also reduces energy consumption.

Integrated refrigeration equipment

Machine 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 maintenance

Cabina%20back
At 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.
