The chuck may be runout, or the rails may be worn.

If a boring cutter is used, go again without removing the workpiece.

If you use an internal hole knife, use the program control, do only one precision mold, after changing the program, the knife is changed to make up the small to if you do not change the small original place and then go to the knife, the hole must be large), and then increase the reprocessing.

No, it's changing. Every step. If the hole size is 10 to the case, throw it with sandpaper.

If it is a 30 hole, drill it with a drill bit of about 27 first, then use G81 boring, leave 10 wires on one side, and finally use G76 fine boring.

The reaming allowance is the amount of depth of cut that is set aside for reaming. Usually, the reaming allowance is smaller than the reaming or boring allowance, and the reaming allowance is too large to increase the cutting pressure and damage the reamer, resulting in poor machining surface roughness. When the margin is too large, the rough hinge and the fine hinge can be separated to ensure the technical requirements.

On the other hand, if the blank allowance is too small, the reamer will wear out prematurely, and it will not be able to cut properly, and it will also make the surface roughness poor. Generally, the reaming allowance is that for larger diameter holes, the allowance cannot be greater than. For hard materials and some aerospace materials, the reaming allowance is usually smaller.

Precautions when installing boring tools.

When carrying out boring, the first work to be carried out is to install the boring cutter, the quality of the boring cutter installation is related to the quality of the boring, when installing the boring cutter, special attention should be paid to whether the main blade plane of the boring cutter is kept horizontal with the feed direction, only when they are in the same horizontal plane, can ensure that the cutting angle of the cutting edge is correct.

When boring, the initial boring should be adjusted according to the processing demand, and the fine boring allowance should be reserved.

The size of the allowance of the fine boring hole of the boring machine is determined by the size and material of the inner hole of the workpiece, for example: the size of the inner hole is about 30-500mm, and the material is steel, then the allowance is.

The boring machine is mainly a machine tool that uses a boring cutter to boring holes in the workpiece, usually, the boring cutter rotation is the main movement, and the movement of the boring cutter or workpiece is the feed movement. Its machining accuracy and surface quality are higher than those of drilling machines.

The size of the allowance is determined by the size and material of the inner hole of the workpiece, for example: the size of the inner hole is 30-500mm, and the material is steel, then the allowance is.

Generally, it is not immutable, and it is adjusted according to the actual situation of processing, and it should also be judged according to the machining effect of the tool. It is not recommended to be below and below, if the rough boring cutter marks are large, there is a risk that the fine boring will not be completed.

It has been finely bored, why do you need to leave a margin, after rough boring, according to the size and length of the hole to leave a different allowance, the larger and longer the less left.

Lathe boring clamping is round or regular equilateral convenience, other irregular parts need to do special tooling, boring machine for irregular or large box lathe difficult or difficult to process workpieces can be very good.

This is a machine tool that mainly uses a boring cutter to boring existing prefabricated holes in the workpiece. In general, the rotation of the boring cutter is the main motion, and the movement of the boring cutter or workpiece is the feed motion. It is mainly used for machining high-precision holes or finishing multiple holes at one positioning, and can also be engaged in the processing of other machined surfaces related to hole finishing.

Drilling, milling, and cutting can also be carried out with different tools and attachments with higher machining accuracy and surface quality than with drilling machines. The boring machine is the main equipment for the processing of large box parts. Threading and machining of outer cylinders and end faces, etc.

Summary. The reason for the burr when threading is that the starting point tip has the nature of extrusion, and the speed of threading itself is the pitch, so the force of the rapid contact with the workpiece and the force after the stable cutting of the workpiece are not the same, and the knife is lifted quickly at the end of the thread, and it is not a smooth cut, so there are burrs at the beginning and end of the thread. It's not that it can't be changed, the corresponding blade is conducive to cutting according to the workpiece material, and it will generally be processed later, but if it is finished, there will be no burrs, and at the end the empty margin will go a few more knives.

I wish you a happy life! Hope mine is helpful to you ha.

Hello dear <>

The problem with boring on CNC lathes is that the dimensional accuracy does not meet the requirements.

When the car is grained, there are a few light cars without burrs, and there are no two that run out and one has burrs, what is the reason for this?

1. First of all, it is necessary to determine the depth of each boring hole, and when calculating the depth of each boring hole, the diameter of the boring hole, the size of the boring head, the shape of the boring head and the ratio of the depth of the boring hole to the size of the boring head should be considered.

2. Calculate the depth of each boring hole based on the size of the boring head. In general, the depth of the boring hole should be 1 times the size of the boring head, that is, the depth of each boring hole should be 1 times the size of the boring head.

3. If the boring depth is more than 1 times the size of the boring head, the shape of the boring head should be considered. Generally speaking, the sharper the drill shape, the deeper the depth, and the more round the drill shape, the shallower the depth. Therefore, according to the shape of the boring head, Li Zheng can calculate the appropriate boring depth.

4. Finally, according to the ratio of the depth of the boring hole to the size of the boring head, determine the depth of each boring hole. Generally speaking, if the ratio of boring depth to boring head size is greater than 1, the boring depth should be greater than 1 times of the boring head size; If the ratio of the boring depth to the size of the boring head is less than 1, the boring depth should be less than 1 times the size of the boring head.

Hello hail, the main methods of hole depth control of ordinary boring machine are as follows:1The automatic depth control device is adopted, and the automatic depth control is realized by setting the depth parameters of the eggplant; 2.

The tremor rock depth control table is adopted, and the depth control is carried out according to the depth parameters in the table. 3.The depth control ruler is adopted, and the depth control is carried out according to the depth parameters on the ruler according to the requirements; 4.The depth control screw is adopted, and the depth control is carried out according to the depth parameters on the screw.

There are two main methods of hole depth control of ordinary boring machine: one is the preset depth control, and the other is the actual depth control. Preset depth control means that after setting the hole depth, the hole depth setting value is input into the controller, and the controller controls the operation of the boring machine according to the input hole depth value to achieve the set hole depth.

The actual depth control refers to the actual depth of the boring machine is input into the controller, and the controller controls the operation of the boring machine according to the actual depth value to achieve the set hole depth.

The common boring machine hole depth control method is a technology used to control the hole depth, which can ensure the accuracy and quality of the hole by controlling the hole depth and travel. There are two main ways to control the hole depth of ordinary boring machine, one is to control the hole depth by adjusting the feed of the boring cutter, and the other is to control the hole depth by adjusting the speed of the boring tool. In addition, the hole depth can also be controlled by adjusting the cutting parameters of the boring tool, such as cutting speed, cutting depth, cutting width, etc.

You can choose the appropriate boring machine hole depth control method according to the actual needs to ensure the accuracy and quality of the hole.

There are two main methods for the controller of the hole depth of the ordinary boring machine: the quick moving handwheel and the limit setting. Remorse.

Quickly move the handwheel: The user can control the boring depth by moving the handwheel quickly, and this method can quickly and accurately control the depth of the clear hole.

Limit setting: The hole depth can be preset by using the limit setting, and a certain position of the handwheel can be maintained to maintain the accuracy of the hole depth.

The control methods for the hole depth of ordinary boring machine are usually as follows: 1. Measure the thickness of the boring hole with a fixed-length ruler, and then adjust the corresponding depth on the boring cutter cover; 2. According to the thickness of the material to be bored, adjust the depth of the boring cutter first, and then carry out boring; 3. According to the sharp ridge of the boring material, measure the hole depth with a digital display table, and adjust the depth of the boring tool in real time.

According to the working parameters set by the hole depth, the boring cutter is rotated in turn to meet the depth requirements. Number of branches.

Depth gauge for precise hole depth control.

Depth sensors are used for high-precision hole depth control.

The automatic depth control system is adopted to achieve the first high degree of precision destruction and easy to operate the depth control.

The control handle is used to move the boring tool up and down to control the hole depth.
