It is considered that the contact stiffness between the grinding wheel and the workpiece depends on the number of the abrasive grains in contact with the workpiece and the support stiffness of a single abrasive grain. In this paper, the calculating method of the theoritical contact stiffness of grinding wheel in grinding operation was proposed.

With the development of technology and industry, the grinding process is developing in the direction of high speed, high precision, and high productivity [1,2,3,4].However, due to the particularity of glass materials, edge wear and surface smoothness should be considered during processing [5,6,7,8].At present, most of the grinding of workpieces with …

In the grinding process, the magnitude of the grinding force has a serious impact on the surface quality of the workpiece and the tool life. In order to explore the influence of different grinding parameters on the grinding force in the ultrasonic-assisted grinding process, this paper carried out an ultrasonic-assisted single-grain high-speed grinding experiment.

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

In the transform gear train, the meshing coordinate system of cycloid gear and pin gear pair is established as shown in Fig. 2.The coordinate system of (S_{f}) is fixed with the frame, so called a fixed coordinate system, and the coordinate systems of (S_{2}) and (S_{P}) are fixed and rotate with cycloid gear and needle gear, respectively; (O_{2}) and (O_{p}) are …

The formula to calculate D for multiple noise exposures is: D = [C1/T1 + C2/T2 + Cn/ Tn] × 100. Cn is the total time of exposure at a specified noise level, and Tn is the duration you have to stay below for this noise level (see table above). Let's say you have mowed the lawn (93 dBA) for 60 minutes and used your grinder (100 dBA) for 10 ...

Wang et al. developed the abrasive belt grinding propeller system and presented global and local material removal model to calculate the grinding force according to the elastic deformation characteristics of the workpiece and contact wheel. The mean machine allowance was 250 μm with machining allowance fluctuation controlled in the range of ...

1) Grinding wheel speed and workpiece speed. 2) Grinding wheel sizes and workpiece sizes. 3) Infeed amount. The above relations are explained by the following figure. D: Diameter of grinding wheel (mm) d: Diameter of workpiece (mm) V: Wheel speed (m/min) v: Workpiece, wheel speed (m/min) f: Feedrate.

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
