Five problems in deep hole bit operation (Emerson)
There are certain operation control standards for the use of deep hole drills. In order to let you know more about the use of deep hole drills, let's take a look at them briefly
1. The unstable value of the power supply voltage of the deep hole drill shall not be greater than 5%. The voltage and frequency of the machine tool motor label shall be consistent with the power supply, otherwise, the motor shall not be started to work.
2. Before using the deep hole drill, check whether the oil level of the lubricating oil written into the TTW guide and feed spindle is in the center of the oil level gauge. If the oil level is lower than the lower limit, add oil to the middle of the oil level gauge.
3. Lubricating oil, the deep hole drilling oil can only be used according to the oil specified in the machine manual or the oil with chemical composition similar to the regular oil.
4. The cooling oil tank is planned to be separated into two parts. Only the level of clean oil is allowed to be higher than that of unclean oil, so as to prevent the unclean oil from flowing into the clean oil tank. The cooling oil level can be checked once a week through the control window installed on the side of the unclean oil tank. The liquid level must be higher than the symbol under the glass to prevent the oil pump from losing its function due to air inhalation. The guide rail of deep hole tool bed adopts double rectangular guide rail which is suitable for deep hole machining machine tool, with large bearing capacity and good guiding accuracy; the guide rail has been quenched and has high wear resistance. Deep hole honing machine bed guide system. Before drilling into the workpiece, the deep hole drill relies on the tool guide to ensure the accurate position of the cutter head, and the guide sleeve is close to the end face of the workpiece. It is necessary to see the liquid level through the upper glass, otherwise it is difficult to ensure circulation.
5. When the V-belt of the spindle needs to be replaced with a new one, it should have a satisfactory pre tightening force to prevent sagging, heating and noise or shaking during operation. If such problems are found, tighten the belt from the beginning. Deep hole honing machine bed guide system. Before drilling into the workpiece, the deep hole drill relies on the tool guide to ensure the accurate position of the cutter head, and the guide sleeve is close to the end face of the workpiece. After working for an hour, the belt should be tightened from the beginning to compensate for the initial elongation and grooving of the belt. Check the belt tightness every 40 hours and tighten the belt from the beginning.
