In the whole process of tube plate opening,Tube sheet bitProcessing manufacturers need to pay attention to what is the super heavy machinery plant, often encounter parts tube sheet hole processing. Before processing, it is necessary to master several common problems of tube sheet drill bit processing manufacturers. Only by knowing such things can the work be done better and some problems can be avoided when machining the tube sheet drill bit. So, let's learn what to pay attention to during the processing of the lower tube plate drill bit!

The chip groove adopts a double-edged chip groove, which can reduce the width of the chip without changing the feed rate and increase the thickness of the chip. According to the cutting principle, the influence of the width of the chip on the cutting force is greater than the thickness of the chip. Therefore, under the same cutting area, thin and thick chips are more labor-saving than thin and wide chips. The chips are cut straight and the chip discharge speed is fast, which can bring out some fine ribbon chips and reduce the friction and pressure between chips and the hole wall. The space occupied by the straight chips is small, which is conducive to the entry and exit of the coolant. Then drill with a parabolic groove drill, than the twist drill has many advantages.

First, the core of the tube sheet drill bit becomes thicker and the rigidity of the drill bit is improved; secondly, the helix angle becomes larger, the chip groove becomes wider, the chip receiving space of the chip groove becomes larger, and the cooling condition is improved. When sharpening, the knife tip adopts the cross sharpening method. Shorten the chisel edge and reduce the axial force; the part of the drill bit adopts the form of group drilling, so that the angle of the front surface becomes larger. The double-edged chip causes the narrow chip to be expelled in a straight line along the root of the chip groove of the drill bit.

Cooling radial drilling machine cooling is to pump out the coolant directly into the orifice, natural flow into the orifice for cooling. When the drill bit is started, it can be sufficiently cooled. After digging to a certain depth, because the discharge direction of the chip is opposite to the flow of the coolant, the outflow of the coolant to the cutting area gradually decreases, and the deeper the hole, the more obvious. This is to ensure the durability of the drill bit. During the drilling process, the cutting amount can be selected according to the material of the workpiece, the depth size of each time can be explored, and then the drill bit can be raised to solve the problem of chip removal and cooling.

When performing the opening processing operation of the valve plate, it is necessary to pay attention to the sequence of automatically cutting off the power supply. Other operations can only be completed after the switching power supply enters and the operation interfaces of the management system are all started. After standby, the gate can only be closed after the corresponding component stops at the appropriate position. Secondly, after the machine tool is transported, before moving each axis, be sure to check whether the interference interferes with the movement of the machine tool and whether there is leakage in the working area. Secondly, when you operate the machine tool control panel, you can't wear gloves. Keep your hands clean and free of oil. Attention should be paid when operating the machine tool. In order to prevent operation errors, it should be within reach.
