Rotary diamond dresser dressing vitrified cbn wheel
rotary diamond dresser dressing vitrified cbn wheel is used for inner-surface grinders with vitrified CBN wheels, angular grinders, cylindrical grinders, centerless grinders and surface grinders.
Single and multi-groove ball bearings forming grinding diamond rollers
Single and multi-groove ball bearing forming grinding diamond rollers can be divided into single and multi-groove deep groove ball bearing forming diamond roller shafts and single and double row angular contact ball bearings. In the dressing of the grinding wheel, the diamond-like roller uses a high-precision diamond profile to form and dress the grinding wheel by direct cutting. According to the processing technology and the required precision and the difference in roughness, the groove of the bearing is selected to be ground. Angles, groove depths, locks, bearing diameters and other dimensions participate in grinding and diamond roller manufacturing methods.
Deep groove ball bearings are the most common type of rolling bearings. Divided into different types such as single row and multiple rows, the basic type of deep groove ball bearing has an outer ring, an inner ring, a group of steel balls and a group of cages.
Deep groove ball bearings are mainly used to bear pure radial load, but also can bear radial load and axial load at the same time. When it only bears pure radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of deep groove ball bearings is very small, and the limit speed is also very high. Especially in high-speed operation conditions with large axial loads, deep groove ball bearings are more superior than thrust ball bearings.
Corresponding to the diamond roller of the deep groove ball bearing, according to the characteristics of the deep groove ball bearing, its main guarantee accuracy is the groove arc profile of the bearing, the groove arc radius of curvature, and the groove between the double rows.
