Characteristics of drilling machine and matters needing attention

The manual drilling machine consists of a manual transmission mechanism, an axial feed mechanism, a guide mechanism and a clearance adjustment mechanism. The manual transmission mechanism consists of a main shaft, a wrench connected with the end of the main shaft and a drill bit and a sleeve drill connected with the lower end of the main shaft. The axial feed mechanism consists of a handwheel, a worm wheel, a nut and a screw; the guiding mechanism passes through the box cover at the upper end. The clearance adjusting mechanism is composed of adjusting nuts connected with the spindle above the nut and two plane bearings on both sides of the upper end of the nut 6, which are connected with the lower end of the nut and the screw rod. The product has good sealing performance, stable work, low labor intensity and can be used in one machine for many purposes. It can be used as a device for installing branch pipes without stopping the conveying work and drilling under pressure.

1. Choose the right bit or bit according to the material drilled. 2. Adjusting the appropriate speed according to the drilling material, the hot low melting point material of the drill bit will soften if the speed is too fast, and the soft material will adhere if the speed is too slow. 3. According to the depth and diameter of the hole drilled, determine the number of times the driller enters the tool. 4. Drilling machine is a high-speed rotary feed cutter, which needs to pay attention to safety protection. 5. Attention should be paid to ensuring the sharpness of the bit. It is necessary to grind or replace the bit regularly. 6. Oil and lubricate the drill shaft regularly.
