Heavy duty polishing and belt grinding jack. For belt linishing, grinding and polishing of surgical instruments, faucets, castings and other work pieces.

The best MB20 that we have ever had. 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.

The mono-base design of the multiLine models allows grinding widths (Z-axis) of up to 900 mm. The compact, steel base designed multiLine model is equipped with linear guides in all three axes. The feed axes Y and Z are driven via servo motors and ball screws. For machines up to 2,000 mm the table is driven via ball screw (KGT). For longer tables up to 6,000 mm a linear motor (LIM) is used. The standard version of the multiLine comes with high-precision linear scales for positioning of the vertical axis. The direct drive grinding spindle with up to 37 kW guarantees optimal torque transfer. To meet your requirements this model can easily be customized through a large variety of available options like different types of overhead and table mounted dressing units for using Al-oxide or CBN/diamond grinding wheels.

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
