Conventional and superabrasive grinding make the LG-400 a perfect solution for the most demanding industries

At the next EMO 2013 DANOBAT fair, the LG-400 horizontal internal and external grinding machine will be exhibited together with the DANOBAT OVERBECK IRD-400 horizontal internal and radius grinding machine, and the capability of both will be displayed for providing prosthesis machining solutions for the medical sector. In addition to providing solutions for this sector, the LG grinding machine range offers excellent results in the high precision machining of small parts such as cutting tools, ultra-precision parts for the hydraulics industry, parts for the automotive sector, etc.

The LG-400 is an intermediate model within the LG grinding machine range that allows parts with a maximum diameter of 300 mm to be machined with a maximum grindable length of 400 mm, while the top of the range model accepts parts of up to 300 mm in diameter and 600 mm in grindable length.

DANOBAT offers turnkey solutions with different kinds of fully integrated loading and unloading. At the next EMO 2013 fair, the LG-400 model will be exhibited with its robot + pallet loading and unloading system. Both with this system and with the others that can be included in this model, gantry, conveyor, etc., much reduced part change times are achieved, typically between 2-6 seconds.

Depending on the specific needs of each customer, it is possible to add a multi-wheel B axis equipped with grinding heads that allow the use of wheels of up to 500 mm x 80 mm whether conventional, superabrasive or a combination of both technologies, thus increasing production capacity and improving the final quality of the parts.

Slides are driven by means of linear motors fitted on preloaded bearings, and the wheel head by means of a cooled electro-spindle that allows a large range of peripheral speeds with maximum torque, covering the range necessary for grinding with both conventional abrasive (45 m/s) and superabrasives (20 to 120 m/s). These drive systems together with the bed manufactured from natural granite for the absorption of vibrations give the whole the rigidity and stability necessary for achieving excellent precision.

The LG-400 offers the latest technology with a modern and ergonomic design that allows the machine to be adapted to the needs of each customer with options such as automatic loading/unloading systems, multi-wheel B axis, synchronised tailstock, moving window (facing the wheel), different types of diamond dressing (radius, crush, wheel), etc.
