1、OPTOFORM 40 The worlds most competitively priced Ultra Precision Lathespecifically designed for manufacturing bothINTRA-OCULAR LENSES and CONTACT LENSES.DescriptionThrough the use of AC Linear motors, in conjunction with precision linear scales (laser scales), the machine operates at a resolution of
2、 less than 10 nanometers. Linear motors (non-contacting magnetic technology) provide smooth, cog-free operation while also eliminating all maintenance associated with conventional drive systems.The slides are mounted on a solid, natural granite base. This gives the machine excellent thermal stabilit
3、y and a high degree of vibration damping. Granite is also very stable over long periods of time, ensuring accuracies remain unchanged over the life of the lathe. The base is supported and isolated from the fabricated steel frame with a 3-point vibration isolation system. Incorporated into this frame
4、 are the electrical and pneumatic controls, as well as the computer and spindle drive. The spindle is of an air-bearing design, capable of running up to 10,000 RPM. It uses an air-operated precision collet. These are available in various configurations and depths for both standard or fixed stop (dea
5、d length) use. Ergonomic Features毕业设计论文代做平台 580毕业设计网 是专业代做团队 也有大量毕业设计成品提供参考 QQ3449649974All lathe functions are accessed from a touch-screen, which can be positioned to suit the operators comfort. A small JOG control panel and EMERGENCY STOP panel are provided for convenience and safety. All contro
6、ls are provided through the touch-screen. No keyboard is necessary, but one is provided. It can be plugged into the keyboard port if required. The operator is prompted to enter data using a graphical keyboard on the touch-screen. Tool-setting is accomplished by a specially designed, spindle-mounted
7、LVDT holder, in conjunction with an automated process accessed from the machine control screen. The lathe can accommodate up to 6 tools. It takes fewer tools when using any of the optional fast tool servo systems such as VariForm, VariMax, or the FTS-1000. The Fast Tool Servo devices replace one of
8、the three dual tool holders.All items needing service or routine maintenance,are accessible from the front or rear of the lathe (air filters for example). Service records are maintained on the machine in the Maintenance software section.PerformanceUsing an advanced linear motor drive system, the fol
9、lowing results were consistently obtained using a PMMA lens blank, 12.7mm diameter and a cutting speed of 25mm/min.Surface Finish: 12nm (.012m) RMS or less Form Accuracy: 0.3m or less Specifications Machine configuration: Two-Axis, offset “T” designBase: Natural GraniteVibration isolation: Passive V

12、(These packages run on all OPTOFORM machines.) The package supplied with the machine is suited to the end-users applications. These software design packages create either job files (.JFL files which describe data points in 2 or 3 dimensions) or MiniFiles, which use arcs and lines to describe the geo
13、metry of the surfaces being lathed.Examples of these packages include:Lens Design Software (version 3) “LDS-3” for contact lens design. All aspherics, spheres, multi-curves and edge designs. MCG (Multi Curve Generator) programming software creates part programs from user specified coordinate points
14、or geometrical data. Commonly used for mold tool design and IOL designs. OPTO-CAD converts AutoCad generated designs (.dxf files) into MiniFiles, which the Optoform machines can all process. Used mainly by IOL and mold tool producers.TURBO-LENS for spherical, multi-spherical, bifocal contact lenses
