Abstract
The invention discloses a granite machine tool guide rail. Particularly, through processing, the granite material is mounted on the machine tool used as the machine tool guide rail. The granite machine tool guide rail of the invention has the advantages of high abrasive resistance, no stress, no expansion and contraction, good rigidity and large internal damping coefficient. Compared with the conventional metal guide rail, the granite machine tool guide rail of the invention greatly prolongs the service life, improves rigidity and precision of the machine tool guide rail, and can be widely applied to all kinds of precision machine tools.
Description
Technical field: the present invention uses the granite material on lathe through the processing assembly as machine tool guideway, and the granite machine tool guide rail of Any shape is with rectilinear motion or rotatablely move all suitable.
Background technology: at present the guide rail of mechanical machine tool is the metal material manufacturing and forms, and is respectively cast iron, medium carbon steel, high-carbon steel, its case hardness between Rockwell hardness HRC20 °-60 °, through hard-faced rigidity layer between 0.1-1mm.
The easy abrasion condition of lathe metal guide rail has following several:
1. case hardness is not enough, easily wearing and tearing.
2. heating is expanded and is produced wearing and tearing even scorch.
Stress deformation and produce wearing and tearing in addition scorch.
Machine tool guideway is wearing and tearing in a single day, and fit clearance increases, and the form and position tolerance precision reduces, and the complete machine precision is reduced.
Summary of the invention: the existing machine tool metal guide rail wears no resistance because of the distortion of metal structure own, weares and teares easily and reduces geometric accuracy." granite machine tool guide rail " provide extra-high-speed wearability, internal stress free, be close to can not expand with heat and contract with cold, extremely low coefficient of friction, below be more granitic technical parameters:
1. machining accuracy can reach below the 0.5 μ m.
2. wearability exceeds 5-10 doubly than cast iron.
3. coefficient of thermal expansion and contraction is little, and not yielding similar with the indium steel, temperature influence is atomic.
4. elastic modelling quantity is little, is higher than cast iron.
5. good rigidly, internal damping number system number is big, and is bigger 15 times than iron and steel, can shockproof, damping.
6. granitic chemical property is stable, not the erosion of easy-weathering, energy acid and alkali resistance and etchant gas.
Granite have non-conductive, magnetic conduction, a position are stable.
8. granitic mohs hardness is about 6 to 7 degree.(Mohs scale is to be used for measuring the wear-resisting degree of stone material)
Subordinate list: Mohs scale:
1. 7. 8. topaz 9. corundum 10. diamonds (object of reference: steel 5.5 glass 5.5-6 files 6.5) of quartz (granite) of talcum 2. gypsum 3. marbles 4. fluorite 5. apatite, 6. feldspars (granite)
Comprehensive above metal and granitic technical data relatively, granite have high abrasion, unstressed, thermal coefficient of expansion is extremely low, internal damping coefficient greatly, the advantage of good rigidly, be applied on the machine tool guideway, improve 5-10 times service life than traditional metal guide rail.
Technical scheme: the technical solution adopted for the present invention to solve the technical problems is:
Rough machined granite guide rail is fixed on the fuselage of lathe (assembling of granite guide rail sectional).Reach the drawing requirement through grinding again after the assembling.
Description of drawings: accompanying drawing is that the present invention assembles schematic diagram.Interior setscrew (2) is contained in granite guide rail (1) inner chamber in advance, by foundary weight (4) granite guide rail (1) is abutted against the step of fuselage (5), fastening bolt (3) is fastened on granite guide rail (1) above the fuselage (5) by the via hole of fuselage (5).
Claims (1)
1. a granite guide rail (1) is fastened on the fuselage (5) by interior setscrew (2) foundary weight (4) fastening bolt (3).According to claim, the granite machine tool guide rail of Any shape is with rectilinear motion or rotatablely move all within claim.
