Recently, Shanghai ANTISHICNC Company has an American customer who needs to purchase a CNC lathe for processing double-row angular contact ball bearings. The size of the bearing is: 42*82*36mm.
Double row angular contact ball bearings can bear radial loads and axial loads acting in two directions. The bearings can limit the bidirectional axial displacement of the shaft or shell, and the contact angle is 30 degrees. This bearing can provide a higher rigidity bearing configuration and can withstand overturning moments, as shown in the figure:
According to the customer’s needs, ANTISHICNC engineers successfully matched the customer with a CNC flat bed lathe – H32i model, with a maximum disc processing diameter of 320mm. The processing accuracy can reach T6 level. The following are the basic parameters of H32i:
| Specifications | Unit | H32i |
| Max. Swing over Bed | mm | Φ320 |
| Max. Swing over slide | mm | Φ70 |
| Max. disc machining diameter | mm | Φ320 |
| Max. turning length (with row cutter) | mm | 280 |
| Spindle through hole diameter | mm | Φ48 |
| X-direction travel | mm | 280 |
| Z-direction travel | mm | 330 |
| Total mains power | KW | 6 |
Shanghai ANTS Machine engineers will introduce you to the detailed processing process:
1.Rough turning: A rough turning operation is performed to remove excess material and create a basic cylindrical shape.
2.Precision turning: Precision turning operations are performed to obtain the required size (42*82*36mm) and surface finish.
(1), End face: Create a flat surface at the end of the bearing.
(2) Boring: Enlarging a hole or creating an internal cylindrical surface.
(3), Grooving: Cut grooves for retaining rings or seals.
(4), Finishing operation: Apply finishing cutting to achieve final surface finish and dimensional accuracy.
3.Quality control and inspection
(1) Dimensional inspection: Use precision instruments (such as micrometers, calipers) to measure key dimensions.
(2), Surface finish inspection: Check the surface roughness to ensure it meets specifications.
(3), Hardness test: If the bearing material has requirements, perform a hardness test to ensure that it meets the mechanical performance specifications.
