2020-3-16 Surface finishing for x-ray mirrors is typically conducted through a series of abrasive processes, such as grinding and polishing, and is thus time consuming. The purpose of this study is to streamline and enhance the surface finishing process based on unique high quality grinding techniques for the production of x-ray total reflection mirrors.
2021-6-17 Internal grinding, similar to surface grinding, is a workpiece material removal process using the abrasive grain as the cutting tool. In internal grinding, the contact length is longer than that of the surface being ground under the same sized grinding wheel, and the chip is not easy to eliminate.

2014-11-3 Grinding and polishing process for polymethylmethacryla te（PMMA）is investigated based on previous proposed position/force control method of robotic automation grinding and polishing system. Through the analysis of the material removal mechanism of single abrasive grain，a model based on the elastic mechanic theory and Preston theory is proposed for predicting the surface of workpiece material
2013-10-15 The powder obtained by grinding swarf for 12–20 min in the presence of PMMA has a highly developed surface. During SAM adsorption, the bonds between the surface atoms and other atoms weaken, which facilitates the nucleation of microcracks.
The optimal processing parameters of the grinding and polishing for PMMA are determined by conducting the single factor experiments. Applying the processing of determined parameters，the surface deformation and microcrack of PMMA do not exist.
2010-9-24 Grinding is an important industrial operation that is used for the size reduction of materials and production of large surface area. However, the existence of a limit fineness is not unusual when the comminution process is performed by a dry grinding method. The importance of wet grinding mills increases steadily because of an increasing demand for fine and ultra-fine particles (less than 1 μm) .
2013-3-1 Compared with activated carbon, PMMA pore former produced quasi-spherical pores with relatively uniform pore size distribution, and had a less influence on impairing the strength and hardness. Hence, PMMA was an appropriate pore former for vitrified bond CBN grinding wheels better than activated carbon.
2021-4-7 As shown in Fig. 20, the cylindrical roller grinding experiment was carried out on the DDSG grinding machine, where the cylindrical roller was observed to be continuously rotating and feeding along the straight groove during the grinding process. The machining results of the grinding experiments showed that the selected PMMA-PTFE grinding disc materials could meet the optimization conditions and machining requirements of the DDSG grinding
The dry paint peeling powder is prepared by grinding waste PMMA into fine particles of 20-50 mesh, then adding 65% aluminum hydroxide, alumina or barium sulfate, or adding unsaturated polyester with 10% 20% non PMMA, and then grinding them into fine powder of 20-60 mesh.Spraying it on the metal surface can not only effectively remove the paint and other dirt on the metal surface, but also remove the paint
Grafting poly(methyl methacrylate) or PMMA from natural rubber (NR) using ATRP process, NR has to be transformed into bromoalkyl-functionalized NR (NRBr) acting as ATRP macroinitiator.

2017-11-23 In the grinding process of balls, the balls are placed on a cast iron plate with grooves parallel to the grinding wheel. The process takes place over several stages which can be grouped into two overarching phases: rough grinding and finish or lapping operations. 2.1.1 Rough grinding. For the rough grinding stage, the grinding wheels tend to be made with silicon carbide grains and vitrified bonds.
Having worked with bearing manufacturers worldwide, TGS understands the challenges of bearing grinding. Precise grinding of the outer diameter of the bearing is critical to all future manufacturing processes. TGS’ ability to meet extremely tight tolerances (.00002″) ensures that out-of-spec bearings will not join the costly scrap pile.
The face grinding is the first process in the PFC of bearing parts. The ground face generated after this process is the reference for all subsequent grinding processes & stands as a reference for achieving the accuracies at every stage.
Solutions for every size & type of bearing. Our machines are designed for high productivity; with grinding rates up to one part every 3 seconds in some processes. We build with flexibility in mind, so we know our machines can handle any type of bearing.
