1. Automatic oil supply system of gear box: The design principle of the rocker drill is the vertical gear. The traditional lubrication method is to use the gear speed to throw the lubricating oil onto the gear. Lubrication has been proved by practice. The traditional way of the top gear is dry grinding. After several months of use, the customer finds that there is a lot of noise, and the top gear must be changed after one to two years.

2. Zhongjie Rocker Drill adopts lubricating self-bearing to enter, fully lubricate the bearing, from the bearing down to the gear, as long as the oil is changed frequently, no brutal operation, there is no reason for the bearing and gear to be bad.
3. The company has developed energy-saving and high-efficiency motors in terms of high efficiency and energy saving. It uses the principle of Taiwan turret milling motors to reduce the rotor height and increase the roughness, increase the torque of the motor, and reduce the power of the motor. Experiments have proved that the motors used by the company now Energy saving 2 kWh per hour compared to traditional motors.
4. The energy-saving motor is calculated according to 12 hours per day, 12 * 2 = 24 degrees, 24 degrees per day * 365 days = 8760 degrees, saving the next equipment model in two years.
5. Absolute copper core motor forward and reverse rotation High and low speed The minimum speed is 34 revolutions and can be tapped directly.
6. The column is locked securely. Traditionally, the column is locked without a safety device. Two more AC contactors are required to install this setting. The product of Zhongjie drilling machine is equipped with safety automatic protection device. In case the worker forgets to release the lock, it can automatically cut off the power to prevent the rocker arm from pulling up the column and sliding the lifting wire.
7. The spindle has a travel switch protection system. During automatic feed, forgetting to release the automatic feed will cause the spindle to top the car. This protection spindle is not easy to be damaged.
8. Automatic pump oil system: change the traditional dry grinding, copper turbine fully lubricated and wear-resistant.
9. Super audio quenching gears: wear-resistant and high hardness. Quenching should be done according to the operating regulations, not by burning. The process of quenching and grinding teeth should not just say that noise is a general measure of gear quality. The noise of grinding teeth is small and there is no noise. Conversely, the noise decibel is above 100 decibels. All gears use CNC worm grinding precision grinding.
10. The switches used on the machine tool are all brand switches, and the AC contactors are directly supplied by Shanghai Electric Appliance Factory Company through bidding.
11. The screw adopts the brand manufacturer. The brand manufacturer does not directly use the round steel car, but strictly follows the process requirements, tempering heat treatment and other strict process requirements. The special screw equipment has a high smoothness after the use of cylindrical grinding and the service life exceeds Ordinary lead screw 2 times. The wire mother uses copper wire mother. The price is three times that of the traditional screw.
12. The Zhongjie rocker drill strictly follows the production process requirements. First pull the parallelism of the spindle box with a dial indicator, measure the swing of the rocker arm, and then measure the circle of the spindle box. and many more
