) , but the diameter that VTG4000 machines exceeds 4000mm (157in.
) , it is the dimension of bearing of the biggest wind- driven turbine, offer good precision at the same time. What the linear electric machinery on Nextpage linear axis makes VTG4000 fast, firm is static press slideway to increase precision. Accompany static press slideway, pressure oily infuse arrives between fluctuation slip slip goes up since float, form to be mixed without attrition almost tall response slip system. "The machine tool of standard measure, ball guide screw is used on the axis, maintain about the appearance deviation of 3-µm " Johannson explains. "This machine tool maintains appearance deviation to be less than 1µm, and feed resolution 0.
1µm. " the core that linear slip is Lidköping machine tool, the liquid is static press slip, the union of hermetic seal and linear electric machinery produced tall tigidity, high accuracy, the system of maintenance-free. Control of variable blade of turbine of high quality promotion changes the point of view that paddle bearing allows wind speed of basis of lamina of wind- driven turbine to optimize oneself or stall condition produces in fresh gale, this kind of large bearing is machined after accordingly the dependability of this kind of bearing decided VTG4000 of efficiency and safe operation multipurpose is designed to use second setting directly, carry out the turning of head of two substantive works and grinding. Two jobs head can be decorated afresh according to need, normally the circumstance issues grinding / turning or grinding / grinding. Machine tool 4.
The move that prop up is in the X- axis of 5m two spare parts jobs relative to side first, allow grinding and turning tool to approach a part. Exceed 35 tons when weight of a few spare partses, VTG4000 special be able to bear or endure to be out of shape and heat up change, have the aid of controls hydraulic pressure oil and implementation of cooling fluid temperature this at rigor. Heavy-cut grinding / system of high resolution grinding / Zun Dongzhu uses liquid of drive of linear electric machinery static press slip, vertical distance: 860mm, transverse journey: 2460mm, the biggest acceleration: 1m/s2, the oldest rate: 1m/s. Resolution: 0.
01mm, configure origin of Source of servo of coder of linear electric machinery, high resolution, closed circuit: KMT Lidköping " we take the place of from 1970 begin to use a liquid static press slip to replace scroll slideway, undertake they and linear electric machinery combinative we were brought again faster, more high accuracy, bigger add, reduce rate, " respecting of plant manager Jörgen Möller. "The finger that sees when you you can use you makes 25, when the runner shaft coming back of 000kg moves, you can realize the liquid is static press a system to have how outstanding. " the athletic precision of 4 main slip builds the high resolution coder that configures feedback of complete closed circuit in Siemens linear electric machinery. The liquid is static press slip to near 0 clash, seeing coder in order to realize first time of freeboard precision Johansson be installed finally without any crawl is the EMO exhibition 2007 on VTG4000, lidköping passes strict test to sensor. "We compared different grating rule to assemble our referenced slip to go up, chose show the most outstanding that, "Johansson respecting. "Important is uniform encoding implement successive length at least 4.
5 M, and should very strong fight contaminative ability, leinishao (the optimal choice that the SiGNUM series of Renishaw) is these requirements. We had installed them 4 all linear slip, and did not go out show any issues. Our circumgyrate workbench has same design principle, radial of configuration hydraulic pressure and axial bearing, empty hermetic seal and moment of force are motor. The pitching moment motor of circumgyrate workbench has coder of a high resolution to be used at servo closed-loop control. We did similar analysis to choose SiGNUM angle coder.
"Coder conduces to angle of set grinding main shaft likewise, a very main machine tool function, anyhow, use again static pressure / the freeboard precision of slip of linear electric machinery, the angle that any exceeding will undertake fine tuning during emery wheel nap. Leinishao (the installation of magnetic angle coder of Renishaw) is on the B- axis of wheelhead. These coder expose the slashing condition at machine tool environment to fall, design of optics of their blame contact, blame and IP68 are sealed, ensure they are avoided suffer cooling fluid and the effect that cut bits. Number or the journey that imitate outputs LM10 to allow to achieve 100 M and the high speed exercise that achieve 25 M/s (4 M/s is in 1µm resolution) . Coder configures the LED of a compositive setting, quickened installation and changing need to install environment or oscillograph miscellaneously in order to use Yu Fu so. "Leinishao (Renishaw) coder a the biggest characteristic is they are installed very easily, "Johansson complements. "Of the grating rule that accompanying attach decorate with reading head nearby, indicator light makes case of two parts connection can be observed easily. Other trademarks already also were used, however, we like Leinishao (the tall wear that Renishaw) product installs easy, high resolution and complex environment to fall as a result of it.
"The working coordinate that sets the part the machine tool for accurate ground is, VTG4000 uses Leinishao (the osculatory bougie that wireless signal transmits Renishaw)RMP60. After installation of semifinished product spare parts arrives on the machine tool, RMP60 from the mount inside knife library, use the exact position of main feature. This data is used to the coordinate system in updating a loop, in order to be used at fast and accurate treatment. Leinishao (before Renishaw) contacts bougie to be used at treatment, measure with the spare parts after treatment. The position that indicates workpiece accurately and condition are measured before treatment, and its mental allowance, out of round is spent etc, and be measured below the line later evaluate good car and / or the result after grinding.
