Precise France presents SPF 50 compliance cutting. This system consists of an electrospindle with ball and socket join for compliance on X and Y axes (flexible system). Its displacement is controlled by a pneumatic damping system which tends to realign the spindle into its constant effort axis.
1-Compliance, 2-Electrospindle, 3 – Perpendicular plane to the spindle axis The HEN 50 Fisher electrospindle is primarily intended for robotized machining operations, for example:
- milling of aluminum or cast iron parts
- deburring of aluminum or cast iron parts after machining to remove all burrs
- milling of composite materials or deburring of various metallic materials.
2D Compliance This device is implemented for deburring irregular parts in terms of burrs, forms and dimensions, by a possibility of small movements in all directions perpendicular to the axis of the spindle and under almost constant effort. The value of the completed chamfer is also quasi-constant. Machining effort and stroke of compliance are adjustable. This device simplifies the programming of robot trajectories by limiting the number of learning points.
Deburring Machining of chamfers from 0.5 to 2 mm is possible depending on settings and size of burrs. Programming is done by learning by reducing the programming points. By its shape, it is able to enter into complex parts (spindle nose diameter 50). Feed rate from 2 to 15 m/min can be adapted according to material, shapes, burrs and chamfer sizes.
Copying Copying is done by milling with form tracking by a pin in contact with the profile of the part. The flexibility of the system allows following profiles of complex parts.
Simple pneumatic power The pressure is adjustable from 0.5 to 6 bars by a pressure regulator and it proportionally determines the compliance effort. This device requires 5 micron-filtered and lubricated air and the spindle must be put under overpressure conditions to prevent any entrance of chips. This requires an extra power supply of 5 micron-filtered dry air at the pressure of 0.2 to 0.3 bars. Lubricated air cannot be used for over-pressure (washing of bearings).
