BAND SAW BLADE SHARPENER AF 531


The Alix AF 531 sharpener is a machine for sharpening band saw blade teeth of log saws. It is a simple and functional machine for correctly sharpening several types of blades. It consists of a compact steel, extra strong structure that considerably reduces any type of vibration. Tooth shaping is achieved using the traditional double-cam system. The grinding wheel dressing device ensures a constant and correct grinding wheel profile until it is completely worn out. Nonetheless, this profile can be changed according to the thickness of the grinding wheel used, to optimise the profile of all types of teeth. Vertical adjustment of the blade support stand is motorised which allows the blade to be precisely positioned. Brake vice closing is pneumatic with adjustable braking force.
The switchboard features an ergonomic and user-friendly panel.
The machine is produced in the right or left handed version: a wide choice of optional accessories means that you can customise the machine according to your specific needs.
On request, the rotation speed of the grinding wheel can be variable to keep the peripheral speed of the same constant; this, together with the abundant supply of coolant, ensures an excellent finish of the tooth and avoids dangerous thermal alterations on the blade body.
