How to use the guide sleeve of the deep hole drilling machine in the transformation of lathe: make a support for the guide sleeve between the position of the workpiece to be clamped and the bit to be clamped, and use this support to guide the direction of the bit.
Deep hole drill tool rotation:
1. Compared with workpiece rotation, tool rotation has higher adaptability. Whether concentric hole or eccentric hole, regardless of the size of the hole diameter, can be better solved on the general lathe.
2. Design tooling according to the actual situation, and fix the workpiece on the supporting plate of the machine tool. The guide sleeve can be designed and installed on the front end face of the workpiece to guide the deep hole drilling into. This method does not need to process guide hole before deep hole machining. Greatly improved the processing efficiency. According to the actual situation of the workpiece, the installation of the tool of the deep hole drilling and boring machine can be selected according to the actual situation: when the machine speed and the minimum feed can meet the processing requirements, the taper handle of the rotating fixture is directly installed in the taper hole of the machine tool spindle, the tool is installed in the rotating fixture, the machine tool spindle drives the tool to rotate through the rotating fixture, and the feed motion is provided by the large support plate.
If the spindle speed and the minimum cutting speed of the machine tool can not meet the processing requirements, it can be adjusted by adding a spindle speed increaser. The speed increase ratio of the spindle speed increaser is 3.81. When machining small holes, the spindle of the machine tool can almost meet the processing of all holes after the speed increase. At the same time, the minimum cutting speed of the machine tool is reduced by 3.81 times, and the machining range is wider. The installation of the main shaft speeder is very simple. The taper handle of the speeder is installed in the taper hole of the main shaft of the machine tool, the taper handle of the rotating fixture is installed in the output shaft of the speeder, and the cutter is also installed in the rotating fixture.
