1. It is used as the main shaft cutter cylinder. It is used for the vertical main shaft. It is fixed with a support and vertically installed on the upper plane of the main shaft box.

2. The fixed surface of the support for fixing the cutter cylinder shall be perpendicular to the axis of the main shaft, and the allowable error shall not exceed 0.05mm/100mm, so as to avoid the deflection of the cutter cylinder, which will exert force on the cylinder wall and affect the service life.

3. Adjustment of knife stroke position. After the cutter cylinder is installed, first adjust the stroke position of the spindle when cutting. When the upper chamber of the cylinder is ventilated, the hydraulic piston rod pushes the tension rod in the main shaft to make the tool cylinder fully extend, make the tool handle push out of the main shaft hole, and then measure the distance a from the end face of the pull rod to the end face of the main shaft (see the schematic diagram). The tool jacking amount shall be determined according to the up and down movement of the tool magazine manipulator used. Generally, the tool jacking amount of BT30 spindle is 0.2 ~ 0.4mm, that of BT40 spindle is 0.4 ~ 0.7mm, and that of BT50 spindle is

0.5~1mm。 However, it must not be less than the minimum amount of top page cutter.

4. To adjust the distance "a", loosen the bolt on the lock washer and adjust the distance between the fixing screw and the pull rod. After adjustment, carry out cutting test and detection until a reaches the required value to ensure that the cutting tool can be loosened and removed without excessive extension; Otherwise, the tool arm of the magazine will be bent and the main shaft will be damaged. Tighten the bolts on the lock washer after adjustment.

5. After adjusting the cutting position, check the spindle. Under the condition of with or without a knife, the tail of the broach rod on the spindle should not contact with the compression screw. Otherwise, the spindle will rub with the compression screw. If the above occurs, adjust the length of the tool pull rod, the cutting stroke or select the cutting cylinder with a larger stroke.

6. Adjustment of microswitch position. Adjusting the position of microswitch is directly related to the automatic tool exchange program, which should be paid attention to. Adjust the microswitch at both ends. When the pressure bar is at the limit position, gradually approach the microswitch to the impact block. When the switch just acts (the sound of spring plate bouncing can be heard), press the switch down for 0.5 ~ 1.5mm and fix it. A delay relay shall be added in the PLC electric control diagram, and the delay time shall be reasonably set to coordinate the action of tool drawing, broach and tool magazine, so as to avoid premature tool drawing or tool loosening

1. Before shutdown, the last processed tool shall be sent back to the tool magazine before the spindle is cooled, and the bad habit of placing the tool on the spindle for a long time shall not be formed. Otherwise, about 10% of the tool handles will rust at the tool handle due to long-term thermal expansion and contraction and corrosion of cutting fluid.

2. The compressed air source shall be dry and clean. Discharge the air source frequently to deal with the accumulated water in the three elements, otherwise, the service life of the solenoid valve will be greatly reduced, resulting in the failure of the knife cylinder to work normally.

3. The pressure of compressed air shall be stable, and the pressure shall be kept within the range of 0.6 ~ 0.8MPa. The pressure is too small, and the output of cutter cylinder is not enough; Excessive pressure will affect the service life of the oil seal. Pressure switch detection shall be added in the gas circuit to control the minimum value of gas circuit pressure.

4. The mounting surface of the cutter cylinder shall be perpendicular to the axis of the main shaft, with a tolerance of 0.05mm/100mm

5. The solenoid valve coil voltage shall meet the requirements (usually DC24V)

6. It is recommended to use ISO vg32 anti-wear hydraulic oil in the oil cup. During initial refueling, move the knife cylinder up and down for many times to exhaust the air in the oil cylinder. The liquid level of the oil cup shall be kept within the scale line.

7. Check the hydraulic oil in the oil cup regularly and replenish or replace the hydraulic oil in time. Generally, the first oil filling shall be used for more than six months. In case of oil filling later, it is recommended to replace the oil seal when the interval is shortened to within one month. The same type of hydraulic oil from the same manufacturer shall be used for oil replenishment or replacement, and other hydraulic oils shall not be mixed.

8. Select the appropriate knife cylinder to avoid too much or too little knife. Generally, it should be 3 ~ 4.5 times of the cutting force of the main shaft

Generally, 3.5t cutter cylinder is selected for 40# spindle

Generally, 4.5t cutter cylinder is selected for 50# spindle

50# high power spindle generally adopts 6T cutter cylinder

9. It is better to configure the air source separately for the machine tool. If the air source is shared with multiple machine tools, the lifting capacity configuration shall be increased, and the pressure fluctuation shall be avoided. 10. The microswitch of the knife cylinder must be firmly installed without loosening to avoid sending wrong signals. The selected tool handle and pull nail shall be qualified and consistent with the standard size, and shall not be too long or too short, resulting in inflexible cutting and damage to the main shaft, tool arm or cutter head.
