Embodiment Construction
[0009] Such as figure 1 As shown in , a processing technology for chuck thin slices, the processing technology is as follows: 1. Rough turning the end face of the outer circle, leaving a margin of 0.1 mm, and leaving a margin of 0.025 mm for the outer circle; 2. Cutting the groove to reduce the final cutting Stress, grooving Φ53.8±0.05mm and removing allowance for cutting to Φ32.5mm in diameter; 3. Cutting the end face of the annular groove, leaving an allowance of 1 mm in diameter and 0.025 mm in the bottom of the annular groove; 4. Rough boring A Φ16 cutter bar is used for the hole, with an allowance of 0.15 mm for the diameter and 0.04 mm for the end face; 5. A Φ12 cutter bar is used for digging the inner groove, and the size of the inner groove meets the requirements of the drawing; 6. The thickness of the outer circle of the finishing car is guaranteed to be 1.7±0.05mm , indirectly guarantee the total thickness of 3.1±0.08mm, and ensure that the diameter meets the standa...

The invention discloses a machining technology of a chuck sheet and belongs to the field of machinery machining. A chuck sheet workpiece is simple in shape, but has high requirements for accuracy of size, form and position, cut-off deformation is large through common machining, and the machining difficulty is very high due to the fact that flatness of two planes of the chuck sheet workpiece is required to be 0.01 mm; and aiming at the defects of the prior art, the invention provides the machining technology of the chuck sheet. The machining technology comprises the steps as follow: roughly turning an excircle; performing grooving; cutting an end face circular groove; roughly boring a hole; digging an internal groove; finely turning the excircle; finely boring the hole; finely turning the end face circular groove; and cutting off. With the adoption of the machining technology of the chuck sheet, the problems that in the prior art, the cut-off deformation is large during chuck sheet machining, and the machining difficulty is very high due to high requirements for the accuracy of size, form and position of the chuck sheet are solved.
Description
[0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing technology for chuck thin slices. Background technique [0002] The shape of the chuck sheet workpiece is simple, but the size and shape accuracy are high, and the cutting deformation is large when using conventional processing. Since the flatness of the two planes of the chuck sheet workpiece is only required to be 0.01 mm, the processing is extremely difficult. Contents of the invention [0003] The object of the present invention is to provide a processing technology for chuck thin slices, which solves the problems of large cutting deformation of chuck thin slices in the prior art and extremely high processing difficulty due to high requirements for workpiece size and shape accuracy of chuck thin slices . [0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme, a processing technology of a chuck sheet,...
