Embodiment 1
[0017] A method for surface grinding of a 15mm thick titanium plate, comprising the steps:
[0018] Step A, spot grinding: use a grinding wheel to spot grind some surface defects;
[0019] Step B, repair welding: under the protection of argon, repair welding is carried out to fill up the recesses that have been spot-ground and exceed half of the thickness tolerance of the plate;
[0020] Step C, overall coarse grinding: use a ceramic abrasive belt with a belt size of 36 mesh to perform overall rough grinding on the upper and lower surfaces of the plate, the width of the abrasive belt is 80mm, the motor speed is 1500rpm, the abrasive belt The traveling speed is 2m / min, the grinding amount per pass is 50μm, and the cooling spray device is used to cool the plate during the coarse grinding process;
[0021] Step D, overall fine grinding: use a resin abrasive belt with a belt size of 100 mesh to perform overall fine grinding on the upper and lower surfaces of the plate, the width ...
Embodiment 2
[0025] Use substantially the same method as in Example 1 to carry out surface grinding on a 15mm thick titanium plate, but in step C, the grain size of the abrasive belt is changed to 80 meshes, the width of the abrasive belt is changed to 150mm, the motor speed is changed to 800rpm, and the grinding amount per pass Change it to 30μm; in step D, change the grain size of the abrasive belt to 120 mesh, change the width of the abrasive belt to 1300mm, change the motor speed to 900rpm, and change the grinding amount for each pass to 5μm.
[0026] As seen from embodiment 1 and embodiment 2, in embodiment 1, abrasive belt granularity is bigger (mesh number is little), abrasive belt is narrow, motor speed is fast, and the amount of reconditioning corresponding to each rough grinding and fine grinding is larger; In Example 2, the grain size of the abrasive belt is small (large mesh number), the abrasive belt is wide, and the motor speed is slow, so the grinding amount corresponding to ...

Abstract
The invention provides a surface grinding method of a titanium plate or a titanium-alloy plate. The surface grinding method of the titanium plate or the titanium-alloy plate sequentially comprises the step of spot grinding, wherein a grinding tool is utilized to carry out spot grinding on particle surface defects; the step of repair welding, wherein repair welding for leveling up is carried out on parts of the defects having subjected to spot welding; the step of overall rough grinding, wherein an abrasive belt grinding machine with a ceramic abrasive belt or a diamond abrasive belt is used for carrying out overall rough grinding on the upper surface and the lower surface of the plate, and the grain size of the abrasive belt is 30-150 meshes; and the step of overall accurate grinding, wherein an abrasive belt grinding machine with a resin abrasive belt is used for carrying out overall accurate grinding on the upper surface and the lower surface of the plate, and the grain size of the abrasive belt is 100-320 meshes. By means of the surface grinding method of the titanium plate or the titanium-alloy plate, the surface defects of the titanium plate or the titanium-alloy plate can be overcome, and therefore the titanium plate or the titanium-alloy plate which is good in surface quality and long in service life can be obtained.
Description
technical field [0001] The invention belongs to the field of grinding of nonferrous metals, and in particular relates to a surface grinding method of a titanium plate or a titanium alloy plate. Background technique [0002] The surface of the annealed titanium plate has a layer of black oxide, which must be removed. In addition, a good titanium plate or titanium alloy plate surface has a great influence on the performance and life of titanium materials. Therefore, after annealing, the titanium plate or titanium alloy plate can remove the oxide layer by means of surface grinding and make its surface meet the performance requirements, improve the surface quality, and thus increase the service life of the product. Patent CN201020663867 proposes a titanium billet surface grinding machine, including a working surface, a track system composed of a transverse track and a longitudinal track, a grinding head frame arranged on the track system, a grinding head fixed on the grinding h...
