Multi - axis tapping machine adopts the method of rigid tapping and flexible tapping drilling ...

Rigid tapping is tapping tap feed is fixed (rigid), and flexible tapping tap feed is adjusted gap, generally by the spring extension axis of the elastic contraction function to achieve. Tapping is to screw the tap into the bottom hole to be drilled with a certain torque to produce internal threads. Turn left, turn right.

It can be seen from the tapping process that some are similar to the screwing when the thread is matched, that is, there is a rotation and screwing process between the tap and the workpiece. In this process, there is a fixed relationship between the mutual rotation and the amount of feed.

If in mechanical (such as lathe) tapping, this mutual rotation and the fixed relationship between the amount of feed is determined by the machine, it is rigid tapping. There is a certain gap between the mutual rotation and feed quantity given by the mechanical in rigid tapping and the thread of the tap, so rigid tapping can not be perfect;

If in the mechanical (such as lathe) tapping, the mechanical given by the mutual rotation and feed to add an elastic contraction link, that is, flexible tapping. In flexible tapping, the difference between the mutual rotation and feed given by the tapping machine and the thread of the tap can be eliminated by the elastic contraction link. Thus improve the quality of tapping.

What are the methods of drilling the same axis hole of the workpiece by the porous tapping machine?

1. Press the workbench to the base of the cleaning rig, and then fix the baffle to the workbench.

2. The spindle of the drilling machine extends to the position where the workpiece is placed, and the distance between the spindle axis and the baffle and the workbench is adjusted, equal to the large center distance of the support to be drilled.

3. Calculate the distance difference L between the left and right center of the bearing hole, and add a gasket with a thickness of L to the side with a smaller center distance.

4. Fix the bracket on the workbench with pressure plate, washer, bolt, nut, etc.

5. Place a suitable drill bit on the spindle and drill the bracket.

After drilling one hole, flip the bracket over, clamp it tight, and proceed to drill another hole. At this point, the shims are again against the side of the table, with the main shaft still in its original position.

Matters needing attention in the process of operation and use of porous tapping machine are as follows:

When the two basic surfaces of the drillpiece must be stable and reliable, free of oxide skin or impurities liable to fall off, and the surface should be machined as far as possible. Due to the large holes in the workpiece, the workpiece will not be stable during drilling. Therefore, auxiliary jacking auxiliary devices must be added to the side of the workpiece to ensure that the workpiece remains stable during drilling. This method can also be used for boring or milling machines and lathes where same-axle holes are drilled in the workpiece, of course, by clamping the bit to the chuck and securing the workpiece and tool holder to the bracket while drilling in the lathe. In short, this drilling method has a wide range of applications and is worth the joint development of professionals.
