Layoutblocker-PRA CNC-controlled layoutblocker with prismatic blocking. Offers unique features such as layout guided operator instructions, autofill stop, and prism ring identification. Layoutblocker-PRA. CNC-controlled prism-alloy blocker with integrated layout system. Capacity: up to 120 lenses per hour Blocking type: prismatic, plano Lens diameter: 38 - 68 mm, depending on blocking ring Blocking diameter: 36-68 mm, with adapter rings from 36 mm diameter. Lens materials: all plastic and mineral materials. Controls: PC-based control with slot CNC; integrated image processing for determining the position; operation via mouse, function keys on blocker. Axis position: 0 - 180° Prism angle: Type I: up to 6.5° prism; with adapter ring up to 11.5° Type II: 5.5° or 10.5° Front curve (radius): min. 22.5 mm up to max. plano, depending on blocking ring Blocking material: alloy, standard blocking chuck Energy requirements: Electrical power: 110 volts, 9 amps Compressed air min 71 psi to max. 113.76 psi Cooled water: 12 °C Dimensions: 1050 x 950 x 1000 mm Net weight: approx. 100 kg Options: Available with 1 or 2 blocking stations as well as with 2 microscopes, 2 video cameras and 2 monitors The CNC-controlled Layoutblocker-PRA (prismatic with alloy) processes up to 120 lenses/hour. The system automatically adjusts prism angle, prism basis, and the axis of the blocking chuck. While one lens is cooling on the first station, another lens can be adjusted on the second station. The new Layoutblocker-PRA offers enhanced features for more process safety and operating convenience: Parallel working – both stations can be operated simultaneously. The operator can switch between the two stations (except during lens adjustments) Auto fill stop – the alloy fills and automatically stops when correct level is reached. Blocking ring recognition – control software checks whether a blocking ring is necessary and if the inserted ring is correct. Only then can blocking occur. Your benefits at a glance: High blocking precision because of integrated layout system which shows the lens position (X/Y – coordinates and axes position) Error-free blocking: Blocking only occurs in the correct position (applies to most lens types; list upon request. Other lenses are adjusted manually) High precision: because lenses are positioned, clamped, and blocked without being moved Easy to use with integrated layout system, the blocker automatically determines the lens position – lens marking is no longer necessary (applies to most lens types; list upon request. The other lenses are adjusted manually) Windows simplifies the usage. Saves time and reduces errors with data transfer from host computer via barcode scanner High process safety auto-fill feature (alloy blocker PRA & PLA) plus automatic recognition of blocking rings eliminate operator induced errors. More efficient handling by parallel working on both stations and software features. Easy maintenance High capacity - up to 120 lenses per hour Variable diameters, blocking heights and prisms New block rings for PRA and PLA feature separate elements for auto-fill and block ring recognition – improving process consistency & productivity Only after lens is properly blocked, green light appears
