High performance grinding tools for highest productivity! High productivity and good quality components at the lowest cost are the main requirements from todayacute;s leading manufacturers. The costs associated with flute grinding are the highest of all manufacturing steps for producers of drills and cutters, so there is always a need for improvement. This means the selection of the right wheel for the job is essential. The new wheel from xhx offers the user a range of benefits. The new product features an improved bond system, new abrasive types and a new core material. The combination of the features deliver high material removal rates, low wheel wear, low cutting forces, low power consumption and low frictional heat in the contact zone. In turn the surface finish and edge quality of the cutting tools are excellent High Productivity at the lowest cost! Traverse speed improvement about 50 Reduction of flute grinding time about 40 Low cutting forces No thermal damage to the tool Optimized core material Minimal wheel wear Long dressing interval Easily dressed Wide selection of wheels available from stock Workpiece: Carbide Drill: D = 10,6 mm Flute Length: L = 90 mm Material: K40 Machine: Reinecker WZS500CNC Coolant: Oil 40 bar Parameters: vc = 16 m/s ae = 4,8 mm vt old = 25 mm/min => Qw’ = 2,0 vt new = 50 mm/min => Qw’ = 4,0
