Definitions
- the present invemtion concerns a machine tool as defined in the preamble to Claim 1, such as a lathe, for machining a work piece.
- a machine tool compris ⁇ ing a frame with power means, a machining member for removing material from the workpiece, a gear box for transmitting the driving force required to move the work piece and/or the machining means, a guide for supporting the work piece being machined and/or the machining means, an oil space for the gear box con ⁇ taining lubricant, a lubricant space for the guide containing lubricant, and a cutting oil tank contain ⁇ ing cutting oil for lubricating and/or cooling the workpiece and the machining member and from which the lubricant is conducted to the point of machining.
- the gear box With the aid of the gear box lubricant the gear box is lu ⁇ bricated and cooled while the machine tool is running. At the guide, the lubricant eliminates friction, whereby moving the machining means is rendered light. Cutting oil is furthermore employed as cooling fluid at the point of machining when material is being re ⁇ moved from the workpiece with the machining member.
- the lubricant for gear box and guide is mineral-based oil, which constitutes problem waste.
- mineral-based oils are used for cutting oil, diluted e.g. with water.
- problems arise because the substances differing in type do not mix.
- the particular problem then encountered is short service life of the oil, and odour detriments which occur.
- mineral oils produce problem waste and involve considerable disposal costs, and since the cutting oil is frequently diluted with water, separa ⁇ tion of water from the waste oil is cumbersome and cost-intensive.
- the object of the present invention is to eliminate the problems discussed in the foregoing. Specifically, the object of the present invention is to bring forth a machine tool in which the cutting oil and the lubricant which become mixed together will not cause any problems like those in the known art described in the foregoing.
- the object of the invention is further to bring forth a machine tool in which the cutting oil and lubricants used are user-friendly and environment- friendly, meating the standards imposed on environ ⁇ mental products.
- the machine tool of the invention comprises a frame with power means, such as an electric motor, and a gear box for providing the driving power required for moving the workpiece and/or the machining means.
- the machine tool of the invention further comprises a machining member for removing material from the work ⁇ piece, and a guide for supporting the workpiece being machined and/or the machining means.
- the machine tool comprises a lubricant space for the gear box with lubricant, a lubricant space for the guide with lubricant, and a cutting oil tank in which cut ⁇ ting oil is provided for lubricating and/or cooling the workpiece and the machining member, this cutting oil being conducted to the point of machining.
- the guide lubri ⁇ cant and the cutting oil are one and the same lubri ⁇ cant.
- the lubricant to be used is advantageously a water-soluble tall oil-based oil, which is biologically dagradable.
- Significant advantages are thereby gained compared with prior art. inasmuch as the guide lubricant and cutting oil which have become mixed together need not be separated in connection with after-treatment and the spent oil can be disposed of with ease e.g. by burning it.
- using tall oil-based oil is advantageous as to costs compared with use of mineral oil-based oils.
- the gear box lubricant is a water-soluble tall oil-based oil.
- the lubricant which is con ⁇ ducted to the machining means is diluted with water, the lubricant containing about 1 to 10% tall oil-based oil, advantageously 5 ⁇ 3%, and the remainder mainly water. Dilution of the lubricant is performed in order to improve the lubricant's cooling properties and to reduce the consumption of tall oil-based oil. The oil is moreover diluted in order to improve the fluidity of the oil.
- the lubri ⁇ cant contains additives, such as antioxidant, anti- corrosive agent and anti-foam agent.
- additives are added to the oil in order to prevent oxidation and foaming and in order to inhibit corrosion of the lu ⁇ bricated and/or cooled objects.
- the total proportion of additives in the lubricant is thus less than about 5%, advantageously about 1 to 5%, and most advanta ⁇ geously about 1 to 3%.
- the lubricant meets the standards imposed on environment-friendly products.
- the present invention is described in the following with the aid of examples, referring to the attached drawing, schematically presenting a machine tool conforming to the present invention.
- the machine tool depicted in the drawing com ⁇ prises a frame 1 with power means 2 and gear box 4 for providing the driving power required to move the work- piece and/or the machining member 3.
- the gear box 4 has a separate oil space 6 of its own, lubricant 7 being circulated therefrom to lubricate the gears.
- the machine tool depicted in the figure further comprises a machining member 3, with the aid of which material is removed from the workpiece.
- the workpiece and the machining member 3 are both heated, for which reason cutting oil 13 is directed to the point of machining for cooling the workpiece and ma ⁇ chining member 3.
- the machine tool depicted in the drawing comprises a guide 5 for supporting the work ⁇ piece which is being machined and/or the machining member, and a guide lubricant tank 8.
- the machining member 3 is displaced along the guide 5 in a predeter ⁇ mined direction while the guide is lubricated with guide lubricant 9.
- a cutting oil tank 10 has been provided in the lower part of the frame 1, whence cutting oil 13 is supplied with the aid of a pump 11 by a separate pipe system 12 to the point of machining when a work piece is being machined.
- the cutting oil 13 runs off the work piece and the machining members 3 down upon the guide 5 and frame 1, where it becomes mixed with the guide lubri ⁇ cant 9, running further back to the cutting oil tank 10.
- lubricant 14 is pres ⁇ ent, that is, gear box lubricant 7, guide lubricant 9 and cutting oil 13, all of these being one and the same water-soluble, tall oil-based, biologically de- gradable oil. Since the guide lubricant 9 is undiluted lubricant 14, and since the cutting oil 13 is diluted with water, the mixing just described results in the favourable situation that as the amount of cutting oil 13 diminishes, only water need be added in the cutting oil tank 10.
- Characteristics studied in the Example were: corrosion, resistance to oxidation, foaming tenden ⁇ cies, and the substance's emulsifying property. Moreo- ver, samples were subjected to four-ball tests and FZG gear wheel tests. The lubricant samples involved in the study consisted of seven 5-litre sample batches.
- Table 2 shows the results of the corrosion test.
- the quality specification for lubricants regard- ing copper corrosion is la, and quality specification for steel corrosion is zero (no corrosion).
- Table 3 shows the results of the oxidation resistance test carried out in an apparatus conforming to the ASTM G 525 method.
- 100 ml of oil were enclosed in a pressure vessel, this being placed in a water bath.
- the change of oxygen pressure in the pressure vessel was followed during the test.
- the unit of pressure in Table 3 is psi.
- Emulsion characteristics (water separation), according to the ASTM D 1401 method:
- Sample 4 40-40-0 (10 min.) Complete emulsification took place in 10 min.
- Sample 5 40-38-2 25 min.
- ASTM D 2783 ten- second test with stepwise increasing load
- ASTM D 4172 one-houe test with 400 N load
- the tests served to elucidate the wear inhibition and high pressure (EP) properties of the samples.
- EP high pressure
- Table 5 presents the damage load grades meas ⁇ ured as results in the FZG gear wheel tests.
- the damage load grade according to the DIN 51354 method is determined from the weight loss of the gears.
- the identical test procedure, with visual as ⁇ sessment according to the CEC L-07-A-85 method would in most instances yield a damage load grade one step lower: the tooth flanks showed shearing marks over an area more than one gear breadth in aggregate while the weight loss was minor. Specific abrasion was very low in the case of six samples. The lubricant temperatures also remained comparatively low.
- the invention has been de ⁇ scribed by way of example in order to illustrate rhe invention, without in any way confining it.
