Embodiment Construction

[0014] Before the cooling device according to the invention is explained in detail with the aid of FIG. 2 , the known structure according to FIG. 1 will first be explained in detail.

[0015] FIG. 1 shows a known cooling device for a machine tool in the form of a grinding machine generally indicated at 10 . The grinding machine 10 has three linear motors 12 as well as two axial motors 14 and a grinding spindle motor 16 for driving a grinding wheel (not shown). The further described motors 12 and 14 enable a five-axis grinding drive by means of which turbine blades or similar components can also be ground with high precision. The motors 12, 14 and 16 are supplied with fluid in the form of cooling lubricant from a clean tank 22 via a distributor 18, via a forward line 20 in the form of a fluid line, by means of a hydraulic pump P4. The possible level of cooling lubricant in the clean oil tank 22 is indicated symbolically by a level indicator 24 . The cooling lubricant delivere...

Abstract

The cooling device for a working machine (10) for the cooling of a heated fluid such as cooling and lubricating medium has at least one cooling unit (48) which by a pump unit with at least one hydraulic pump (P2) receives fluid filtered by a filter unit (40). A supply tank (38) is divided into a clean tank (22) and a dirty tank (36). The hydraulic pump feeds exclusively filtered fluid from the dirty tank into the clean tank, and an additional independent hydraulic pump (P5) transmits the fluid brought into the clean tank to the cooling unit for circulation.

Description

technical field [0001] The invention relates to a cooling device for a machine tool for cooling heated fluids, such as cooling lubricants, with at least one cooling unit, which receives filtered fluid from a filter device via a pump device with at least one hydraulic pump, the The fluid comes from at least one storage tank; there are also separate clean and dirty tanks, where the cooling unit returns fluid cooled in circulation to the clean tank. Background technique [0002] In cooling devices of this known type that have been used in practice, on a working machine such as a grinding machine, the fluid in the form of cooling lubricant discharged into the surrounding environment is collected in a machine bed pool as a collection station and It is delivered by a hydraulic pump to a dirty oil tank that is part of the cooling lubricant storage tank. The dirty and possibly heated fluid carried into the dirty oil tank is conveyed by another hydraulic pump to the filter device, w...
