Why does the CNC gantry drilling machine experience tap breakage during use Release time：2021-12-07 12:56:32 Number of views:334

CNC gantry drilling machine is a horizontal CNC drilling machine with gantry frame and three spindles. Can process three parts at the same time, high production efficiency. The equipment can be used for the production of simple materials and composite materials, drilling, reaming, reaming, blind hole drilling, internal hole cutting (using special auxiliary tools) and other functions, can be drilled with ordinary twist drill. So do you know why the tap breaks during the use of CNC gantry drilling machine? Let's find out more about it.

1, the correct choice of CNC gantry drilling machine tap: for workpiece hardness is too large, should choose good quality CNC gantry drilling machine tap, such as cobalt high-speed wire tap, carbide tap, coated faucet. In addition, different workplaces use different faucet designs. For example, the number, size and Angle of the chip removal slot of the tap of the CNC gantry drilling machine have an impact on the chip removal performance.

2, CNC portal drilling machine tap quality is not good: material, heat treatment, processing accuracy, coating quality, such as the size difference at the transition of the tap section is too large or the transition corner is not designed to cause stress concentration, and it is easy to break at the stress concentration during use.

3, the tap of CNC gantry drilling machine does not match the processing material: this problem is getting more and more attention. In the past, domestic manufacturers always think that imported is good, expensive is good. In fact, what is suitable is good. With the increasing difficulty of new materials and processing, in order to meet this need, the types of taps are also increasing. This requires selecting the right tapping product before tapping.

4, CNC gantry drilling machine does not meet the accuracy requirements of the tap: CNC gantry drilling machine and clamping body is also a very important factor, especially high-quality tap, only CNC gantry drilling machine and clamping body with a certain accuracy can play the faucet performance. Lack of concentricity is very common. At the beginning of tapping, the tap is not positioned correctly at the beginning, that is, the spindle axis is different from the center line of the bottom hole, and the torque is too large during the tapping process, which is also the main reason for the tap failure.
