THE AVB 750 IS OUR BASIC MACHINE FOR SHARPENING CIRCULAR SAWS WITH CARBIDE TIPS WHICH ALLOWS YOU TO SHARPEN ALL THE GEOMETRIES OF THE BACK AND FACE OF THE TEETH ON CIRCULAR SAWS FROM 100 TO 850 MM IN DIAMETER.
HIGHLIGHTS
- Efficient and fast superior and frontal sharpening thanks to its adjustable feed speed
- All tooth profiles can be sharpened
- Easy to use: suitable for both professional and beginner workshop operators
- Design allows for fault-free, low-maintenance operation for long-term operation
ELITE AVB 750. MACHINE BASE.
The ELITE AVB 750 model is our sharpener for the back and face of all common tooth geometries in carbide tipped circular saw blades for circular blade diameters from ø100 to 850 mm.
One-pass external sharpening for tooth types:
- Flat, inclined, alternating, alternating with bevel, pointed, trapezoid, trapezoid-flat, pointed-flat, alternating-flat, trapezoid-trapezoid.
With 4 CNC axes for complete machining of all common tooth geometries in one cycle, short stroke paths ensure fast sharpening operation.
It uses the famous peripheral grinding wheel system to achieve a saw blade with a perfect edge.
It has a half cabin that allows very quick placement of the saw.
Maintenance is very easy to carry out.
ELITE AVB 750. HOW IT WORKS
Easy to use control panel
All button functions are explained on the buttons with illustrations. And each button is intended to perform a single task. So you know what to expect when you press a button.
The control panel with LCD screen allows programming of the machine, among the programmable values are:
- Tooth geometry
- Grinding path
- Sharpening charge
- Sharpening speed
- Tooth pitch
- Tooth advance nail feed rate
- Number of teeth
- Broken teeth
Up to 7 teeth/minute on flat trapezoid teeth
Up to 7 teeth/minute on flat trapezoid teeth: All movements have been optimized to reduce downtime.
Variable grinding wheel rotation speed from 2,500 to 5,000 RPM
Variable grinding wheel rotation speed from 2,500 to 5,000 RPM: includes frequency converter as a standard feature, so you can adjust the grinding wheel speed to the optimal value needed as well as reduce 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
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.
