Which air cooled oil coolers should be used for cooling of Spindles?
Air cooled fluid coolers can be used to make an offline cooling circuit to cool a large variety of equipment’s, increase their efficiency & optimize their energy consumption. An offline oil cooling circuit has been regarded as an effective technique to cool fluids. Offline systems also called kidney loops, work by using a pump to draw fluid from the equipment’s reservoir, circulate the fluid through an air cooled oil cooler and returning the cool fluid back to a reservoir. High temperatures can quickly degrade fluids and at times even produce byproducts that become particulate contamination in the fluid. Incorporating a filter in the circuit may also reduce the contaminants in the fluid.
Maintaining optimum temperatures in machine tool spindles prevents deviation in spindle center line & heat deformation of the equipment, prolongs lifetime, improves working precision, reduces noise & vibration.
Conventionally refrigerated cooling solutions are used to cool high speed spindles. These are expensive to buy & also have a high running cost. Air cooled oil coolers/ Hydraulic oil Cooler help in maintaining temperatures at relatively steady temperatures and can effectively replace refrigerated coolers in a lot many situations.
