At Befort, spherical precision optics pass through the hands of qualified specialists. They work with a sure instinct and stateoftheart technology. The machine processing of each surface is done on CNC grinding and polishing machines. We produce spherical precision lenses from optical glass, quartz glass and radiationresistant materials with diameters from 3 mm to 130 mm and a curvature radius from 1.18 mm to plane. We make individual lens elements, achromatic systems, concave mirrors, cylinder lenses and other precisely fitting glass geometries to suit your specific application.

What‘s new? • Higher speed of up to 34,000 rpm for finer, more precise work. • The motor is protected from overloading by an automatic cut-out. • Restart protection provides a high degree of safety. • Prolonged motor life through optimum dust protection. Inexpensive to purchase and maintain. Safe to operate. • Cost-effective universal motor in a sturdy plastic shell. • Automatic cut-out if wear occurs to the carbon brushes • Soft start. • Degree of protection: IP 20, Protection class: II Specifically designed for versatile use in mould making • Constant speed under load. • Uses various quick-change hand pieces for milling, grinding, polishing, brushing and filing. • The machine can be operated standing upright or suspended from a hook.

The Peter Wolters AC 2000 double-sided batch processing machine is designed for high-precision series production of workpieces. Thanks to its modular design, the AC 2000 can be used as a fine grinding, lapping, honing and polishing machine. Like all machines in the microLine© series, the AC 2000 relies on proven core components such as the high-precision pneumatic loading system, the non-contact micro-measurement control, the powerful drive technology and the PC-supported machine guidance. The software used for this is specially developed by Peter Wolters and enables complete menu-driven and intuitive operation of the machine. For optimum access to the working area, the entire upper part of the machine can be swung out.

Our gantryLine models can process large, wide and heavy workpieces up to lengths of 5000 mm and widths up to 2000 mm with high precision. Special designs are also available to process wider and longer workpieces. This machine line with its variety of available features is suitable for surface grinding applications all the way through complex CNC manufacturing cells. Next to the horizontal grinding spindle a vertical tiltspindle can be mounted for grinding for example machines beds with under grip. The sturdy gantry-style machine design features a modern vibration-free mechanical table drive, linear guideways in all axes, an over-sized spindle drive as well as ball screws and linear scales in vertical and cross axes. These features guarantee that today’s expectations in the precision machining of large surfaces are met for rough machining and high precision machining as well. The gantryLine achieves highest workpiece precision and surface quality.

The powerLine technology machines are specifically geared towards creep-feed grinding applications. Their mono-base design allows grinding widths (Z-axis) of up to 700 mm with a maximum spindle power of 105 kW. The compact, steel base designed powerLine model is equipped with linear guides in all three axes. All three axes (X, Y, Z) are driven by servo motors via ball screws (KGT). The standard version of the multiLine comes with high-precision linear scales for positioning of the vertical axis. The direct drive of the grinding spindle from 48 kW guarantees optimal torque transfer. Different measuring devices and CD (continuous dressing) units are examples of a wide variety of available options making it easy to customize the powerLine to your individual requirements.

The millGrind series is specially developed for the requirements of machining in the turbine industry as multiple technology solution in one set-up. The modular machine system in travelling table design allows an individual configuration of the machine according to the customers' needs. Automatic tool and diamond roll changing allows the machining to machine with — Al-oxide, CBN and diamond grinding wheels — Drills — Milling cutter — Laser cladding — Measuring of the unfinished workpiece — Measuring of the machine workpiece including rework in one set-up. This guarantees that all machined surfaces run to each other and errors are avoided by repeated re-chucking. In addition to the machining of new blades and vanes for rework a laser cladding device can be added. This allows the measuring, cladding and grinding or milling of the worn areas.

This model is well suited for efficient, economical processing of circular workpieces via surface and step grinding operations. There is no lost time through deceleration, acceleration and reversal as with conventional reciprocation grinding. The grinding wheel remains in contact with the workpiece throughout the grinding process. Single workpieces can be located centrically on the table while multiple workpieces can be located concetrically to optimize table space utilization. A tilting table option allows grinding of chamfers or blade edges (i.e. circular blades), where the table can be tilted +/- 5 degrees. The high-precision rotary table is belt driven. This machine is offered with the xpressCube SPS controls package. A software option is available for step grinding operations. Benefit Overview — Compact and robust machine design — High productivity through continuous contact between wheel and workpiece — High long-term precision — Precision rotary table — Easy to operate
