RER-G Combi 500 Grinding Center
At IMTS 2016, Doimak will display the RER-G Combi 500 Grinding Center with Fanuc CNC and two wheelheads. Designed for grinding OD, ID and threads, the RER-G is equipped with a fast automatic changing grinding head by means of a rotary base turret enabling multiple grinding operations in a single setup. The RER series offers a compact design, external/internal thread grinding in fully automatic transition, OD and gear grinding with optional CBN or peeling and b axis for tapers, flexible multi-task grinding, 2-axis contour dress or full form. The machine is available in a two or three wheel head design.
Additionally, Doimak recently delivered two REN-T spline and gear grinding machines for the machining of cycloid, helical and spur gears. Doimak tested and delivered these models that included integrated probing technology for gear inspection. The machine inspects gear diameter, run-out or teeth alignment just after grinding takes place, reducing machine setup times and providing a more efficient overall machining process thanks to the integrated inspection technology. The following is a brief rundown of some of Doimak's other machining capabilities:
Thread grinding machines for all types of threading technology is the product line most representative of Doimak. The latest CNC technology is implemented with built-in drives and linear motors. These machines include a wide range of spindle designs offering optimum stiffness and damping response. Any type of profile can be dressed thanks to the flexible contour dresser, which also accommodates plunge forming rolls. Multi-ribbed wheels are used for improving process productivity and mass production machines are equipped with robot or gantry type loaders. They offer a higher degree of process automation thanks to different probing and component measuring solutions.
Doimak provides solutions for a wide range of cylindrical shaft grinding applications including extrusion screws and barrels, power generation, printing and more. Different disposition of wheels, including OD/ID solutions with multiple grinding heads mounted in a single swiveling base are available for any type of application requirement. Productivity is improved through the use of in-process measuring systems, steady rests and wheel contact sensors.
Doimak has also developed several machining solutions for the gear and transmission field. Based on the RER thread grinding platform, straight and helical involute gears can be ground using latest CNC technology which includes built-in drives and linear motors. Involute, as well as cycloidal gear profiles, are automatically calculated according to standard gear parameters. These machines offer a higher degree of process automation thanks to different probing and component measuring solutions.
Automotive components such as steering racks, engine and transmission components and crankshaft and camshafts require the latest machining advances. Doimak provides in-process measuring gauges and high performance tools in order to optimize productivity. Mass production machines can be equipped with robots or gantry-type automatic loaders. In most cases, these machines are equipped with hydrostatic drives in order to avoid wear in moving components minimizing production stops due to maintenance requirements.
