Definitions
- the present invention relates to a machine tool with at least one machine part which has temperature-dependent changes in length.
- Such machine tools are generally known.
- the problem of so-called thermal deflections occurs in almost all machine tools.
- certain machine parts heat up as a result of the heat generated in the work area by the running units and the hot chips. This heating in turn leads to changes in length, which lead to displacements within the machine tool.
- a change in length of a guide rail can e.g. cause the position of a limit switch or reference point to be shifted so that all linked dimensions become inaccurate. Furthermore, it is possible that the distance between the tool table and the spindle axis changes, so that the preset machine parameters change, so to speak.
- Thermocontrol is based on temperature and reference measurements, in order to take account of previously measured, known temperature responses in the control.
- the machine parameters to which the control tion changes depending on the temperatures measured in the working area of the machine tool.
- this object is achieved according to the invention in that the machine part is provided with a heat insulation layer where it comes into contact with coolant or can come into contact.
- the inventors of the present application have recognized that it is precisely the influence of the coolant that makes the thermal deflections uncontrollable.
- the coolant supply is switched on and off again and again during the machining of a workpiece in order to cool and / or rinse the tool and the workpiece, ie to remove chips.
- very large quantities of coolant are used, which are collected and returned together with the washed-off chips in a chip pan.
- Many machine tools are also designed so that when the operator door is opened, this so-called tub flush is switched off in order not to contaminate the surrounding area of the machine tool or to contaminate the air with coolant mist. According to the inventors, this opening of the door is sometimes very irregular if, for example, problems arise during the workflow. It is therefore not possible to plan how often the coolant supply is switched on and off.
- the invention does not now take the way of taking these findings into account by increasing the measuring points and / or refining the models depicting the temperature response of the machine tool in the control system; rather, the thermal insulation layer is used according to the invention.
- the machine part is a flat part that is covered on one side with a heat insulation layer.
- the advantage here is that essentially flat parts are covered, which have a large heat transfer surface to the coolant, so that thermal deflections due to intermittent overflow of coolant are particularly significant. It is further preferred if the heat insulation layer is provided with a cover.
- This measure is structurally advantageous, on the one hand it prevents damage to the heat insulation layer by hot chips. On the other hand, the chips cannot get caught on this cover, as would be the case with a heat insulation material which is usually porous.
- machine part is the chip pan.
- the heat insulation layer comprises a foam, preferably styrofoam (brand), the chip tray preferably being designed with an approximately 2 cm thick layer of foam. This measure is structurally advantageous; common, inexpensive and easy to obtain foam sheets can be used to cover the machine part or the chip tray.
- cover plate is approximately 5 mm thick steel plate.
- This measure is particularly advantageous in connection with the chip trough, since it enables the heat insulation layer to be walked on, which will always be necessary during maintenance work.
- Figure 1 is a schematic side view of a machine tool in which the chip pan has a heat insulation layer.
- FIG. 2 shows a cross section through the chip pan of the machine tool from FIG. 1.
- 10 generally denotes a machine tool, which is shown schematically in a side view.
- the machine tool 10 comprises a machine base 11 on which a workpiece table 12 is arranged at the front, on which a workpiece 13 to be machined is clamped.
- the machining of the workpiece 13 takes place by means of a tool 15 which is carried by a spindle 16.
- the spindle 16 is mounted in a manner known per se for height adjustment on a stand 17, which in turn is seated on a first carriage 18 which can be moved horizontally in the drawing plane in FIG. 1.
- the first carriage 18 sits on a second carriage 19 which can be moved perpendicular to the plane of the drawing in FIG. 1.
- the carriage 19 is in turn connected to the machine base 11 via a frame part 21.
- the machine tool 10 corresponds to a structure used by the applicant, the tool 15 can be brought to the workpiece 13 by machining the slide 18 and 19, as well as the stand 17, in order to machine it.
- coolant 23 is emitted from a schematically indicated rinsing tube 22 in order to cool the workpiece 13 and the tool 15 and to rinse off the chips 24 that arise, so that they fall into a chip pan 25, where the coolant 23 also collects.
- the chip pan 25 initially comprises an angled plate 27, on which a heat insulation layer 28 is applied according to the invention. If the machine tool 10 from FIG. 1 is in a thermally steady state, suddenly switched on coolant 23 can lead to a sharp change in temperature of the chip trough 25 and thus of the foot 11, as a result of which a distance between tool 15 and workpiece 13, indicated at 29, can change. These so-called thermal deflections are now prevented or significantly reduced by the heat insulation layer 28. Coolant that briefly strikes the chip trough 25 and is then discharged to the outside into a coolant trough can no longer cool down or heat up the sheet metal 27 and thus the machine base 11 much, since the heat transfer through the heat insulation layer 28 has been significantly reduced.
- FIG. 2 shows a section through part of the chip trough 25. It can be seen that a foam layer 31 rests on the sheet 27 as the heat insulation layer 28, the thickness of which is indicated at 32 is approximately 2 cm. Any commercially available, preferably hard foam which is sold, for example, under the trade name Styrofoam can be used as the foam layer 31.
- the cover plate 33 On the foam layer 31 is a cover plate 33, the thickness indicated at 34 corresponds to approximately 5 mm.
- the cover plate is a steel plate which ensures that the chip trough 25 can be walked on and prevents the chips from getting caught on the heat insulation layer 28.
