Machine Assembly, Manufacturing Machine with Machine Assembly, and Use and Method for Manufacturing Rotational Components

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a specialized machine assembly for manufacturing machines, particularly horizontal production machines, designed for the high-precision processing of rotational components (such as discs, lenses, mirrors, or cylindrical parts). Central to the invention is a workpiece fixture with a main spindle (often a hollow shaft motor) that securely holds and rotates the workpiece along a central axis. Two tool holders are positioned on opposite sides of the workpiece, allowing for simultaneous or sequential machining from both sides without the need to reposition or re-clamp the workpiece. Clamping is achieved with hydraulic or pneumatic systems to ensure high accuracy and repeatability.

Use CasesContent extracted from patent full text and abstract with AI.

• High-precision production of rotationally symmetric parts, such as optical discs, lenses, mirrors, and scientific components needing ultra-precise, parallel surfaces.
• Simultaneous double-sided machining for metal, glass, ceramic, or plastic components.
• Manufacturing of beam-guiding discs for scientific instruments (e.g., electron optics, particle accelerators).
• Production of ultra-flat or plan-parallel components used in high-tech optics, metrology, or semiconductor fields.
• Automated and high-volume production environments requiring fast setup and minimal re-clamping for each part.

BenefitsContent extracted from patent full text and abstract with AI.

• Improved precision and parallelism by allowing both sides of a part to be machined in a single setup.
• Reduced setup and alignment errors, as the part does not need to be re-clamped or flipped during manufacturing.
• Enhanced manufacturing speed by enabling simultaneous or sequential dual-sided processing.
• Reduced risk of deformation, clamping errors, and geometric inaccuracies inherent in traditional single-sided or re-clamped manufacturing workflows.
• Adaptability for various materials (metals, glasses, ceramics, plastics) and part shapes (especially cylindrical or rotationally symmetric parts).
• Supports high automation and efficiency, beneficial for large batch manufacturing or applications with stringent accuracy requirements.
