The ELITE AVB 850 is an automatic double-wheel sharpener designed specifically for circular saw blades with tungsten carbide tips (TCT), compatible with diameters ranging from 100 mm to 850 mm. Its capability to perform simultaneous sharpening of both the face and the top of the tooth in a single setup makes it the fastest machine in its category.

Key technical features include a 10″ color touchscreen that offers intuitive control and real-time program editing. The AVB 850's system operates without hydraulics, which decreases maintenance needs and enhances operational reliability. Equipped with 5 CNC axes (A, B, C, X, Z), the sharpening process is precise and fully automated, ensuring consistent high-quality results.

The double-wheel design allows for exterior sharpening in a single pass and is compatible with multiple tooth geometries, including flat, beveled, alternating, and trapezoidal shapes. The closed cabin of the machine ensures quiet operation and offers quick access for maintenance and loading parts. Additionally, the control system allows for the adjustment of numerous parameters such as angles, geometry, number and pitch of teeth, as well as sharpening speed, which can be adjusted between 2,500 and 5,000 RPM using a frequency converter. The cooling system is efficient, operating with water-soluble or grinding oil coolants, featuring a 220-liter tank with removable metal filters for easy cleaning. With compact dimensions of 1650 x 1200 x 1900 mm and an approximate weight of 660 kg, the AVB 850 is easy to install in industrial spaces, with mechanical and electrical access situated at the rear for convenient maintenance.

Highlighted technical specifications include: blade diameter of 100 to 850 mm, mandrel diameter from 10 mm, maximum blade thickness of 8 mm, tooth pitch up to 120 mm, upper wheel diameter of 125 mm, face wheel diameter of 175 mm, wheel motor power of 0.33 kW, and supported angles including hook from -10° to +35°, bevel from -45° to +45°, and clearance from +5° to +35°. The sharpening stroke can go up to 25 mm, with power supply options of 220/400 V, 50/60 Hz, and 1.5 kW, along with an air pressure of 6 bar. The machine comes equipped with a holder for small (100–210 mm) and large (210–850 mm) discs, a 30 mm centering ring, support for double wheels, 3 mm advance claws, LED lighting, mist extractor, safety enclosure, and preparation for centralized filtration systems.

Optionally, the ELITE FILTRAmaq UNO filtration system can be added, which allows filtering particles down to 2 microns, increasing the coolant's lifespan and improving sharpening quality. In conclusion, the AVB 850 represents an ideal professional solution for workshops requiring precise, automated, and fast sharpening of circular saws with a wide variety of tooth shapes.
