EKOSTAR 760
CNC-controlled sharpening machine for CBN-abrasive grinding

The automatic grinding machine EKOSTAR 760 can be used for cutting off defective teeth and grinding of saw blades with vari pitch toothing.

Advantages at a glance

• Absolut indexing precision and a perfect tooth shape through modern CNC-control system
• CBN-abrasive grinding with effective cooling guarantees high stock removal rates coupled with optimum surface quality
• Automatic path offset: different pitches can be machined using the same grinding wheel thickness, which means a very small number of grinding wheels needs to be stocked
• Blade clamp at the point of the grinding enables the grinding of saw blades with Ø 140 – 760 mm by use of the same clamping flange
• Fast and easy programming using the Loroch Easy-Touch system
• 240 litres coolant tank in steel and high pressure cooling with 6 bar coolant pressure

Technical Data

Besides HSS- and segmental saw blades, the EKOSTAR 760 will also grind friction saw blades. The saw blade data will be entered into the control panel. The computer calculates immediately the tooth pitch and the tooth height and suggests the DIN tooth height difference for tooth shape "C". The computer also automatically calculates the required grinding wheel thickness and informs the operator in case a grinding wheel change will be necessary.

The hook- and clearance angle, the amount of the stock removal and the grinding speed are preselected on the screen: that‘s all, the machine is ready to start grinding ! The chamfering is semi automatic and the machine is available for water emulsion and oil cooling.
