Patent number: 9751131Abstract: The invention relates to a machine for processing plastic workpieces. A machine housing surrounds a working chamber located between a workpiece spindle for rotationally driving the workpieces about a workpiece axis of rotation and a fast tool servo for producing an oscillating feeding movement of a rotary tool in the direction of the workpieces. The workpiece spindle is provided with a carriage which can be driven and is guided on at least two guide surfaces of a guiding arrangement in order to produce a relative advancing movement between the workpiece and the rotary tool. The advancing movement runs transversely with respect to the feeding movement and defining therewith a processing plane in which during processing the rotary tool engages with the workpiece. The guiding arrangement is mounted on the machine housing such that the processing plane extends between the two guide surfaces.Type: GrantFiled: January 24, 2013Date of Patent: September 5, 2017Assignee: Satisloh AGInventors: Steffen Wallendorf, Holger Schäfer, Marc Savoie

Patent number: 8905388Abstract: A block piece for holding a spectacle lens blank has a basic body with a workpiece mounting face portion against which the workpiece can be blocked with a blocking material, and a clamping portion via which the blocked workpiece can be fixed in a machine/apparatus for processing it. The basic body is made substantially of a material having a defined low water absorption and/or is sealed to at least reduce outgassing of water moisture under vacuum conditions, so that the block piece can be used also in vacuum coating processes. Alternatively or in addition, the clamping portion is constructed to be clamped by forces directed essentially perpendicular to the radial direction to cancel out each other and not deform the basic body, and/or the workpiece mounting face portion is provided with a predetermined amount of prism.Type: GrantFiled: February 24, 2009Date of Patent: December 9, 2014Assignee: Satisloh AGInventors: Frank Breme, Laurent Jordi, Edward McPherson, Stefan Schäfer, Marc Savoie

Patent number: 8382932Abstract: A new lens blocking material (adhesive composition 78) is proposed that essentially overcomes the drawbacks of previous blocking materials. This new material combines traditional UV and/or visible light (VIS) curable polymer materials with specially selected filler (s) as a non polymerizing solid in order to achieve or improve certain desirable material properties, including those of low shrinkage, low exothermic heat of polymerization, and improving the ability to deblock, while simultaneously reducing the high cost associated with such UV/VIS radiation curable materials. The new material is being used in methods for blocking a lens blank (54) onto a lens block (62) with a lens mounting face (64) that has a predetermined block curve, in which the number of different block curves required to cover the full range of standard lenses is minimized.Type: GrantFiled: June 28, 2008Date of Patent: February 26, 2013Assignee: Satisloh AGInventor: Marc Savoie

Patent number: 8166622Abstract: A machine for machining workpieces, for example plastic spectacle lenses, has a workpiece spindle which rotates the workpiece about a workpiece rotation axis, and a fast tool arrangement which moves a turning tool in the direction to and from the workpiece, wherein the workpiece spindle and the fast tool arrangement can moreover be moved relative to one another in a direction transverse to the workpiece rotation axis. A tool holder is connected to the fast tool arrangement and carries the turning tool. An engraving tool is spaced from the workpiece rotation axis and has an essentially point-shaped end facing towards the workpiece. The engraving tool can be moved in the direction of the workpiece and away therefrom in a highly dynamic manner via the tool holder, so that a marking can be produced on the workpiece in particular by a needling engagement of the engraving tool with the workpiece.Type: GrantFiled: October 23, 2007Date of Patent: May 1, 2012Assignee: Satisloh AGInventors: Urs Meyer, Marc Savoie
