Types of Boring in CNC Machining
10. Reaming: The workpiece should be positioned by a central drill before drilling with a bit 0.5-0.3 mm smaller than the drawing size. Computer Gong processing | Dongguan high-speed computer gong processing | Dongguan die processing | Dongguan machine parts processing | CNC processing | and reamer reaming. When reaming, attention should be paid to controlling the spindle speed in 70-180 rpm/min.
11. Boring processing: the workpiece should be positioned with a central drill, then drilled with a bit 1-2 mm smaller than the drawing size, then processed with a rough boring cutter (or milling cutter) to the processing margin of only 0.3 mm on one side, and finally finished with a pre-adjusted size fine boring cutter. The last fine boring margin should not be less than 0.1 mm.
12. Direct numerical control (DNC) operation:
13. Before DNC NC machining, the workpiece should be clamped, the zero position should be fixed and the parameters should be set.
14. Open the processing program to transmit data in the computer to check, then let the computer enter the DNC state, and input the file name of the correct processing program.
15. Press the TAPE key and the program start key on the machine tool, when the LSK gleams on the machine controller.
16. DNC data transmission can be processed by pressing the return keyboard on the computer.
3. Contents and scope of workers’self-examination:
1. Processors must see clearly the contents of the process card before processing, know clearly the parts, shapes, sizes of the drawings to be processed, and know the processing contents of the next process.
2. Before clamping the workpiece, the blank size should be measured to meet the requirements of the drawings. When clamping the workpiece, the placement of the workpiece must be carefully checked to be in accordance with the programming instruction book when computer gong processing | Dongguan high-speed computer gong processing | Dongguan die processing | Dongguan mechanical parts processing | CNC processing.
3. Self-inspection should be carried out in time after rough processing is completed. Machinery parts in Dongguan should be processed in order to adjust the data with errors in time. Dongguan high-speed computer gong processing self-inspection content mainly for the location and size of processing parts. Such as: (1) whether the workpiece is loose; (2) whether the workpiece is correctly divided; (3) whether the dimension of the processing part to the reference edge (reference point) meets the requirements of the drawing; (4) the position and dimension of the processing parts to each other. After checking the position and size, the shape ruler of rough machining should be measured (except for arc).
4. Finishing after rough processing and self-inspection. Computer Gong processing | Dongguan high-speed computer gong processing | Dongguan die processing | Dongguan machine parts processing | CNC finishing processing workers should check the shape and size of the processing parts: the basic length and width of the processing parts on the vertical plane are measured; the base point size on the processing parts of the inclined plane is measured.
