PETER WOLTERS AC 1200 is an advanced wafer grinding, lapping & polishing system designed for superior process results and ease of use. This system is designed to produce ultra flat surfaces on a range of materials up to 4µs flat for tight tolerances and tight angles from rough to fine finishes. The product features two independently controlled work heads, each featuring two grinding wheels, two dressers, and two polishing pads. This allows precision grinding and lapping to be performed accurately and reliably at high speeds indifferent to noisy grinding operations or interruption. A variety of processes can be achieved, including rough grinding, fine grinding, and lapping, while automated CNC axes coordinate travel and other functions. AC 1200 features a 7.25-inch touchscreen display, as well as an intuitive control unit with configurable options for gearing, grinding wheel speed, lapping pressure and speed. This ensures that the process parameters for a variety of applications are precisely monitored and adjusted on the fly. It also offers a robust construction with a rigid frame and components, providing superior mechanical stability and precision during the grinding and polishing process. The machine is equipped with a variable frequency inverter allowing for the highest torque and performance. This maximizes the grinding and polishing efficiency and accuracy. The integrated peripheral equipment includes a hydraulic lift table for manual loading and unloading, a slurry recycler and a coolant recycling system. PETER WOLTERS AC 1200 offers intuitive and simple operation, high accuracy and improved process repeatability. This makes it a suitable solution for grinding and polishing of parts from a range of materials including ceramics, silicon, metal, glass and quartz. It is suitable for a wide range of industries, including optical, automotive, medical, metalworking and microelectronic industries.
