What Are The Causes Of Tap Breakage In Servo Tapping Machine?

Servo automatic Tapping Machine is a kind of machine tool which uses tap to process internal thread. It is the most widely used machine tool for processing internal thread. Since the servo automatic tapping machine is facing the market, it has the advantages of lightness, flexibility, high efficiency and other similar equipment can not be replaced, and is deeply loved by the majority of users. It avoids the limitations of lathes, drills or manual tapping, and saves time, labor, teeth, taps are not easy to break, etc. Its remarkable characteristics are widely praised and adopted by users. This machine is suitable for all machinery manufacturing industries. The mainland customers now cover machine tools, mould (factory) machinery, plastic machinery, printing machinery, packaging machinery manufacturers, construction machinery, automotive and motorcycle parts, aero-engines, locomotives and vehicles, tobacco machinery and general machinery industries.

The breakage of servo tapping machine is one of the most common frontal faults, among which the common causes are as follows:

1. The feed speed of servo automatic tapping machine is too fast, which makes the torque too large. Therefore, the manufacturer generally recommends that when the ordinary tap is used to process threads, its speed can not exceed 100 revolutions per minute.

2. The size of bottom hole of servo automatic tapping machine does not match the tap. This situation greatly enlarges the cutting part of the tap during tapping, which makes the tap easy to break.

3. Operator’s mistakes. For example, when the blind hole thread is processed, when the tap is about to contact the bottom of the hole, the operator does not realize that the tap is broken, which requires the staff to strengthen their sense of responsibility.

4. The cutting fluid used in servo automatic tapping machine is improperly selected or not used. A lot of heat is generated during the whole tapping process. Then the tap breaks.

5. The concentricity of servo automatic tapping machine is not enough. The location of tap start is not clear enough, and the torque is too large during tapping, which causes the tap to break.

Self-Conscious Intelligent Manipulator

The American scientific research team trained an intelligent manipulator that can recognize its body independently by using artificial intelligence algorithm. Without input of knowledge of physics, geometry and kinematics, this arm, which is the same size as human arm, can recognize its shape in a short time and make a higher level of motion decision.

In the new study, Columbia University team first allowed a manipulator to move at will and collected about 1,000 trajectories, each containing 100 moving nodes, then used in-depth learning technology to build a self-model of the manipulator.

At first, the manipulator did not know how to shape itself and how to connect the joints. But after less than 35 hours of training, the error between the self-model and the actual physical shape of the manipulator was very small, and the manipulator could accomplish the task more accurately.

Experiments show that under the “calibrable” mode, which allows the manipulator to adjust itself according to the trajectory of motion, it can clamp several small balls into the cup with a 100% success rate. Researchers also replaced the manipulator with a 3D printed defective part to simulate the condition of its body damage.

The results show that the self-model of intelligent manipulator can discover the changes of “body”, and after retraining, it can complete the experiment task at the same level as before.

What Are The Uses And Operating Precautions Of Bench Drills?

The bench drill is powered by the motor and is transmitted to the spindle through the tower pulley. The outermost part of the spindle is a linearly movable sleeve that does not rotate. The rack has a rack structure and the gears are combined to form a longitudinal feed. The mechanism, the main shaft is installed inside the sleeve, the main shaft can rotate freely inside the sleeve, but the up and down movement of the sleeve will drive the upper and lower movement of the main shaft, and the innermost one is relatively long.

Uses of bench drills:
The bench drill can drill holes and fix them on the bench, which is more stable, more precise and more accurate. It belongs to the processing machine. The spindle can move up and down freely on the spline, but it should rotate with the spline. A hollow tower pulley is fixed on the upper end of the spline. The power of the drill bit is transmitted here to the spindle through the spline.

Matters needing attention in the use of bench drills
1. When using a bench drill, you should take good protective glasses and prescribed protective articles, and you are prohibited to wear gauze gloves.
2. When drilling, the workpiece must be clamped and pressed firmly with pliers, fixtures or pressing iron. When drilling thin workpiece, the bottom should be padded with wooden boards.

3. It is forbidden to remove iron chips with gauze when drilling holes, nor to blow with mouth or wipe with hand.4. When the drilling starts or the drilling needs to be drilled through, gently exert force to prevent the workpiece from turning or throwing out. If necessary, water should be added to cool the drilling holes.

5. In the work, the workpiece should be set straight and the force should be uniform so as to prevent the drill bit from breaking.

Roller Burnishing Tool

Roller rolling tool processing principle and processing conditions.
Processing Principle:

The surface of metal surface is rolled by roller to produce plastic deformation. The raised part of the surface is rolled to the depressed part and processed into a smooth mirror-like surface. It is a non-cutting plastic processing method.

Processing conditions:

1. Rolling tools can only process metal materials, and the hardness of materials is below HRC 40 degrees.
2. Rolling tools must be clamped on rotating and feeding equipment for processing. Such as Drilling Machine, lathe, milling machine, Boring Machine, processing center, etc.
3. When working, clean low-viscosity oily working fluid or low-viscosity lubricating oil should be selected (steel parts are made of oil and diesel oil, aluminum parts are made of oil and kerosene in a ratio of 3:7); sewing machine oil or transformer oil can also be used; and the rolling head should be cleaned regularly.
4. Rolling tool shank shape according to machine tool selection (straight shank) Mohs taper shank, BT, CAT, etc.
Widely used in all fields of mechanical processing:
Automobile and motorcycle parts, hardware, electromechanical, petroleum machinery, construction machinery, sewing accessories, air-oil compressor, aerospace and aerospace.

Main Types of Drilling Jigs for Drilling Machine Fixtures

The special fixture for Drilling Machine is generally called “drill jig”. It can be divided into the following categories according to whether the drill jig has a jig body or not and whether the jig body is movable.

1. Fixed drill jig

When the drill jig is used, it is fixed on the drilling machine table. It is used to process large single holes on vertical drilling machine or parallel holes on rocker drilling machine. If the fixed drill jig is to be used in vertical drilling machine to process parallel space system, it is necessary to install the drill jig on the spindle of the machine tool. Generally, the fixed-length cutter installed on the spindle is first inserted into the drill sleeve to determine the position of the drill jig and then tighten it. The drilling accuracy of this method is relatively high.

2. Rotary drill jig

Rotary drill jig is mainly used to process parallel holes on the same circumference or radial holes distributed on the circumference. There are three basic forms: vertical axis, horizontal axis and oblique axis rotation. Because the rotary table has been standardized, and is produced and supplied by special factories as machine tool accessories, the design of fixed rotary drilling die is mostly used in combination with the design of special working fixture and standard rotary table.

3. Turn-over drill jig

It is mainly used to process holes on different surfaces of small workpieces. The use of overturning drill jig can reduce the number of workpiece clamping and improve the position accuracy between holes on the workpiece.

4. Cover type drill jig

The drill jig has no fixture body, and its positioning element and clamping device are directly mounted on the drill template. The drilling formwork is clamped on the workpiece, which is suitable for the small hole processing on the large and heavy workpiece. The fixture and structure are simple and portable, and it is easy to remove chips. However, each fixture needs to be loaded and unloaded from the workpiece, which is time-consuming, so the quality of the drill jig should not exceed 10 kg.

5. Sliding-column drill jig

The structure of the slide-column drilling jig has been standardized and standardized, with different series. When in use, as long as the workpiece shape, size and processing requirements and other specific circumstances, specially designed and manufactured the corresponding positioning, clamping device and drill sleeve, installed on the platform of the fixture body or the appropriate position on the drill template, it can be used for processing.

The Difference Between CNC Milling Machine And CNC Boring And Milling Machine

CNC milling machine is developed on the basis of general milling machine. Both of them have the same processing technology and similar structure. However, CNC milling machine is an automatic machine tool controlled by program, so its structure is quite different from that of ordinary milling machine.

CNC boring and milling machine and processing center are the same principle. They are mainly used for boring holes with larger diameter and deeper depth. CNC milling machine is generally used for milling simple surfaces, but also for milling shallow holes. The bed structure of NC boring and milling machine is larger than that of horizontal type. The bed structure of NC milling machine is generally small in vertical type. NC boring and milling machine has tool base to change tool automatically. There is no tool base for milling machine. Tool change is realized manually in the process of processing.

At present, the CNC boring and milling machine and the processing center can be basically universal, but the Boring Machine for processing parts is limited relatively little. As for programming, the boring machine usually uses every turn
feed when drilling, while the processing center generally uses every minute feed. Because the centripetal force of the boring and milling machine is better, the sliding pillow can extend very long, it is generally used to process box parts with
high hole accuracy and large volume, and the boring and milling machine slides. The pillow is relatively stable, and the surface precision is relatively high. A good machining center can basically be realized.

What is CNC?

In the 1950s, MIT successfully developed the first CNC milling machine. In 1970, the first computer-controlled numerical control machine tool (CNC) was first presented. Now it is widely used, that is, the machining center.

CNC commonly used operating systems Mitsubishi, Frank, Siemens, Heidehan, brother, etc.

CNC machine tools can process most products and most materials. Now widely used are aluminum alloy processing, steel processing, plastic material processing, gold jewelry processing, relief processing and so on.

The auxiliary tools often used in CNC processing are:

1.Programming software, processing programming software includes UG and master cam, etc.
2. Cutting tools, drills, taps, milling cutters, center drills, etc.
3. Auxiliary clamping tools, including middle rod, probe, vise, clamping tool, mechanical arm, etc.
4. Measuring tools, calipers, micrometers, height gauges, cubic elements, etc.

Common CNC brands on the market are Frank, Beijing Carving, Brothers, Mazak, etc. With the progress of science and technology, now the CNC of domestic brands has gradually matured, and has been widely used in the market.

The Bench Drilling Still Maintains Its Current State Of Development

The bench drill can directly tap the pillar to lock safely,In the market, the pillar is usually locked, without safety device, the product is equipped with safety automatic protection device. When the workers forget to release the lock, they can automatically cut off the power to prevent the rocker arm from lifting and damaging the lifting box. The pillar locking adopts the principle of automobile overlapping brake.

The bench drill is the automatic oil supply system of the selected gear box. Oil can be directly hit on the gears to increase the wear resistance of the gears. When there was no such technology before, the whole gear box wall was wasted, not to mention, it could not guarantee the normal oil supply of the gears. There was no such device on the market for machine tools. The drill spindle has control switch protection system, automatic pump oil system, copper turbine wear resistance. The market is generally cast iron turbines, ultra-audio quenched gears wear-resistant, high hardness, all gears using CNC worm grinding accuracy grinding.

What should be paid attention to when choosing multi-spindle for drilling tapping machine?

After the 1960s, due to the application of electronic computers, CNC machine tools, machining centers, robots, and tapping drills appeared. Selection principle of multi-spindle for tapping Drilling Machine:

1. Sensitivity: In general, it is always desirable to maximize the sensitivity of the multi-spindle to achieve the speed and effect of tapping.

2. Accuracy: It is the main indicator that affects the authenticity of the tapping result, but it is not required that the higher the accuracy, the better, because the accuracy of the multi-axis device corresponds to its price, the accuracy is increased by one level, and the price will increase exponentially, so the actual need Choose to go. It should be clear which product is tapped by the Tapping Machine and the accuracy of the multi-spindle is determined according to the requirements of the product.

3. Stability: There are two aspects, namely time stability and environmental stability.
The stability of the environment (temperature, humidity, dust, electromagnetic field, etc.) is a problem that should be considered in any multi-spindle. It is necessary to ensure that the performance of the multi-spindle is reduced under the permissible environmental conditions.
As for the stability of time, it is a key issue to be considered for long-term uninterrupted tapping operation. In addition, the working mode, dimensions and weight of the multi-spindle are also factors to consider when selecting a multi-spindle.
