What is gap compensation-machine tool,CNC mill

What is gap compensation?

The intrinsic characteristic of the machine tool is the reaction. The space in the joint between adhesion, friction and elasticity and rotating machinery is the result of it, such as the ball screw. We compensate the fpc4 scanner, in the X and Y direction, and we are opposed to a consistent method. Fpc4 assembles a Mosaic of the capture algorithm always such that it is always close to each photograph and positive X and Y axis movement so that the machine can be rebound from fpc5 can be effectively isolated

We can look at figure 8. What is the gap compensation algorithm?

In figure 9. By reducing the field of view, the numerical control scanner simulates a distant lens system and improves the orthographic property of the image. This can be seen from improved splicing, especially those features, above or below the focal plane.

Calibrate the image with the numerical control motion.

Usually, we calibrate the image by placing a reference scale in the image field.

However, the unique fpc2 scanner, if you want to scale the image, can be achieved through the movement of the CNC mill. During execution, this method is simpler and more accurate because the resolution is equal to the resolution of the mill.

When the scan object is not convenient to place the reference scale, it is particularly convenient to move the zoom, only the recognition point feature is needed. We know that this could be a corner, a center of a hole, or even a bit of corrosion or abrasion on the surface of the object.

We can also measure the angular error by means of motion, and the effect can be automatically corrected in each image

Let’s look at figure 10. When calibrating the image size we use known linear dimensions.

Figure 11. The calibration of our image scale is accomplished by the precision mechanical movement. And identifiable point moving distance is within the microscope’s field of view of mobile Δ X Y is a known distance. The position change and the actual motion of the machine are both observed by the fpc2 scanner and used to determine the scale.

bipolar winding-High performance mixing motor,thousands of turns

Although there are various kinds of winding methods for fpc8, a basic design has been selected by the industry. High performance mixing motor with bipolar winding is standard. Fpc7 is much more standardized than fpc8, which is usually provided on fpc9 at 17, 23, 34 and 42.

High torque, low-speed equipment is fpc7. Low speed means fewer bearing failures, but fewer bearing failures than in fpc7. When entering the high speed, very obvious torque attenuation will be displayed by fpc7. Although the torque can be provided by fpc7 for thousands of turns, when a large fpc8 is too high in deliverable torque, such as over a few hundred RPM, the obvious recession will still show up. They can work well at low speeds, but at higher speeds, fpc9’s available torque cannot be approached.

After we wanted a lot of thought, discussion, and testing, we developed the fpc7 and fpc6 tools. The fpc7 tool holder USES a standard fpc8, but they provide all the features listed above. The principle of double face contact is fpc7 used, the most modern and expensive tool holders, including the inside it, such as fpc5 and fpc6, but in terms of price, it is compared with the low-cost fpc8 tools, it is very beneficial.

Fpc7 is not required to use fpc1; Whatever the standard fpc8 tools, they can work. However, with the rapid development of fpc7, we are also very satisfied with the selection of fpc8 cone. Low cost, ease of use, high accuracy and simplicity are all provided by the combination of fpc7 and fpc8. One fpc8 taper is made by fpc7 for fpc1 applications.

The machine moves inside a typical office elevator that is permitted by this specification – there is no need for a special freight elevator here. In the process of our research, we found that the physical size of the machine is only slightly changed, namely increased slightly, probably more than double the overseas transport costs, local delivery cost three times, and once the machine to achieve the delivery, in terms of logistics, they will become more complicated. With the development of the design cycle, the weight of our machines has increased a bit, from 900 pounds to 1,130 pounds, but the physical dimensions that we started with are still being kept.

lubrication system-cutting tools,oil film

Overall, the lubrication system has 15 points. The lubrication points on each axis are five. The top and side of the left slide, the top and side of the right slide, and the ball nut are included. On the surface of each slide, we can see a pattern in the length of the saddle. Because the oil point is drilled into this mode, the oil pressure can be evenly distributed throughout the slide.

For some mechanics, they are used to manual machines, which seems to be overdone. To keep oil or oil brushes handy is a traditional practice, on the exposed surface, occasionally we need to apply a little oil. This is good for manual machines. Most manual machine operations are limited, and they are generally limited to the occasional cutting plane, drilling a few holes, perhaps trimming or making pockets are also allowed. The problem you usually find is that more material will be removed when you use fpc2 yourself. This means that the chips are everywhere, with more shafts, usually 40 times more than the manual machines. In all of these movements, the vital importance of longevity in the machine is the retention of the oil film. At this point, we found that oil was not enough.

The protective slide is another function of the lubricant. The area that has not been conveniently accessed by fpc7 is the surface of most methods. Large chips are stuck under the slide and can be prevented by wipers, but they can’t be done by removing tiny abrasive particles. Expose the slider vulnerable to abrasive pollution is on the one hand, on the other hand, they seem to be attractive for a lot of things, such as heavy artifacts, vise, cutting tools, and any things you don’t want to let them fall. To protect all the methods and the ball, we feel that there is a complete method here.

What is lubrication, protection, and road protection

While preloading is effectively provided by these two technologies, significant differences remain. Supersize technology creates pressure points on each ball, which is about four, and each ball has movement in both directions. What is anti-nut technology? It’s going to have a nut in every direction; There are only two pressure points per ball. In terms of price, the preloaded fpc5 technology will be more expensive, because the two ball nuts are needed, but in time, the ball will take longer. This oversized ball technique is a bit cheaper in price, but it can cause the ball to wear out earlier.

Compressibility is the characteristic of the ball nut. In a large amount of cutting force, even when the ball is preloaded, there will be a rebound, and the rebound is obvious. We call him the loss of sport, which is more suitable for the term than the bounce because the real gaps are not available in nuts; It’s compressed, and it’s also powerful. With light, it becomes important to prepress. Fewer lost actions are provided with high preload, but internal stress is also increased. These stresses cause the screws to be heated, the efficiency is reduced, and the life of the screws is shortened. It is essentially the same compromise in determining the preload on the spindle bearing.

For fpc1, fpc4 was selected by us. The characteristics of fpc5 are the medium preload of long life and precision movement.

What is lubrication, protection, and road protection?

Both lubrication and protection are required. The windshield wipers at each end of the cone are useful, and they can help the debris stay in the shell. Oil can also be effectively removed from them. In fact, it’s not a very effective way to apply oil to nuts. The key part of lubrication is the inside of the nut, which should be directly lubricated. Fpc2 has an oil line, which is directly into the lubrication system of each ball nut.

What is fpc6-machine tools,metal cutting,circular orbit

What is fpc6

There are almost ball bearings on all machine tools. Some substitutes simply can’t withstand the high-intensity world of metal cutting, such as fpc7 screws and fpc8 or fpc9, and the low-intensity application is the best.

For those of you who are new, what is fpc6? It could be a simple combination of fpc3 and a screw. This is not a ball, a ball that runs on a circular orbit on a flat surface, like a ball bearing, in a spiral orbit, a ball screw. In one orbit, the sliding and high friction motion of a traditional screw is replaced, generally, by a rolling sphere. As we can see, if it’s a traditional lead screw, it has a significant rebound, and the rebound is about 60% efficiency, as a transfer to the linear motion. If you want to make balls, you can use a zero rebound and 95% transmission efficiency.

The most important thing is the precision of the ball in the machine. Precise movement control starts with a motor. It is fpc3 that converts motor motion to linear motion. If any error occurs in the screw or nut, these errors will directly cause the error in the location of the machine.

Ball bearings and associated cones can be used in various precision grades. The screw part has two basic dimensions: the first is the grade, the second is the application. Applications are generally marked as P, T, or C:

First of all, we generally think that P class is position or precision. The main applications of P grades are high-precision jobs, such as fpc7 machines. Secondly, we call the T or C class a transport grade, and the reason for this design is for practical applications such as lifting, suppression, or other non-sophisticated applications.

high-speed cutting-hydrodynamic membranes,non-hydrodynamic film

Whether it’s the common fpc1 or the fpc1 on the plastic surface, they depend on hydrodynamic membranes if they want to exist. It’s very similar to the oil shock absorber, and as they move faster, if you want to move them, you need more force. As production speeds continue to rise, numerical control centers must move faster and faster. If you can get 200 or 300 IPM per minute, that’s enough; Now the high-end processing centers will also move, moving roughly to 1,000 to 1,500 IPM. At these speeds, the force required for sliding bearings is too high, so it must be fpc1. However, for fpc2, it is not perfect, and it has some limitations. Compared with fpc1 and fpc2, fpc3 always has to do well to avoid pollution. Do you know what the damping effect is? In terms of the damping property, it’s also very low. The damping effect is provided by the viscous oil of the non-hydrodynamic film, and the use of fpc2 can also increase the vibration of the machine, which can reduce the damping of the whole machine.

It is obvious that on high-speed CNC machine tool, it must have low resistance fpc3. For small numerical control machines, as a solution, they are very effective, because only low and high-speed cutting is the job. What is the situation with wood and plastic routers? The router can be constructed to be aluminum and is allowed for these same properties, although in the case of the damping property, it is very low. In our design consideration, a conclusion is obtained by us, because of the high-speed linear motion is not fpc4 needed, however, it must withstand the high metal processing of cutting force, the sliding mode, its damping characteristics is higher, can be the best choice. In terms of longevity and accuracy, we also made the decision to use fpc5, X, Y, and Z in all methods.

hand milling machines-heavy iron frame, hydrodynamic oil film

For many years, iron has been the production of machines. Iron on the iron element is improved by scraping technologies, geometric accuracy can be increased, these techniques at the same time, a better hydrodynamic oil film was created, wear and vibration can be reduced. The degradation of the iron surface is reduced by the technique of surface hardening.

Where is the improvement in iron? No doubt it was because of the addition of chromium. Wear has been further reduced by Chrome. Nowadays, in some advanced hand milling machines, chromium is still common.

A very important improvement is the development of low friction plastic surfaces. The most famous fluorinated polymer is the trademark fpc6. It is characterized by low friction coefficient. At the same time, however, there are many problems. Fpc7 has another name in people’s mouth, which is cold current. Under moderate pressure, it flows, just like a high-viscosity liquid, but the geometry that the designer wants to maintain is lost. When fpc7 is combined with a stronger polymer, such as fpc8, the cold flow can be eliminated, while its low friction performance remains unchanged. A variety of patented products have been developed, but mainly polytetrafluoroethylene. There are many products that are sold under the brand name, such as R, T, D, etc. These products make friction and wear much less. Of course, low friction coefficient of these compounds is just one of the performance, another very important characteristics are shown and that is the static coefficient of friction compared with the friction coefficient is also very similar.

In the sliding surface, usually we know there will be a static friction coefficient (friction, static) exists, and its dynamic coefficient of friction (at the movement, friction, compared to significantly higher. Perfect stiffness does not exist; Whatever it is, there is some spring-even a heavy iron frame.

What is a brief history linear motion – axis design

Is essential for production machinery is high speed, and it is because the high speed makes fpc1 for application is the best choice, although from the cost point of view, is very high. However, the high-speed axis is not required by fpc2. As you can see, our 65 IPM design point is within the performance range of fpc3. When the excellent economy and high-reliability step fpc4 was taken into consideration, fpc5 using fpc4 was the decision we made. The 640-ounce motor is used by us. This allows enough torque to be provided so that a badly overloaded machine can break a terminal before it is close to the required force level.

The engine and standard fpc5 are selected, and fpc4 is also developed closely with the automobile manufacturers. The design is made of sealant, between the layer pressure and the end shell, so there is a whole powder coating primer to prevent contact with the cutting fluid. The high torque of the motor, the further advantage is provided by the low-speed feature, and the direct drive configuration is allowed. The motor is directly mounted at the end of each ball. This eliminates the need for pulleys, belts, and tensioning systems. And from the design, it’s simple, accurate, solid, cheap.

What is a brief history linear motion – axis design?

As we all know, linear motion mechanics has gone through many stages. In the earliest days of the day, the pieces of hardwood were installed on the slide of the machine. And at the very earliest time, woodworking machinery used this technique, and some metal processing machinery applied it.

What is the tool system

A very competitive fpc8 tool market is also due to the wide use of fpc8 cone. The difference between fpc8 tooling and fpc7 tooling is very different.

Although it has no rigid fpc7 type for fpc8, it has enough robustness to deliver fpc5 1.5 HP. Because of the wide availability and low-cost tools it has, the fpc1 taper has been chosen. For many people, fpc1 is just a machine, and it’s just an entry-level fpc2 machine. These people can use the tools they have collected in their past manual workshops to be allowed by fpc8.

What is the tool system?

When we first used fpc8, we had reservations. Although, if we want to deliver the main shaft power we want, we need to be hard enough, but the fpc8 tool is a bit longer than the substitute, so the larger gap is needed. A complete four clearance is required by a standard tool holder, which also takes time if you want to unscrew the bar. While if it is a short running machine, an automatic tool changer is not needed, but, when the change of the tool need a minute or two, it will change, become monotonous and boring. As long as the diameter of the next tool is the same, fpc8 can be used instead of rapidly changing when it is solid.

It is difficult to install fpc8 tools as another problem that bothers us. The offline setting allows the measurement tool to enter the controller tool table, and the need for repeated Z references can also be eliminated. A seemingly impossible combination is what we need:

How can realize rapid change: a tool only needs to be simple to loosen, and tools to be sliding out, and the tool is back to the low clearance: too much clear offline Z height measurement is standard fpc8 tools needed, making the machine’s touch absolute Z position is eliminated, and the variability of tie rod tension not mutually dependent, but independent.

What is a modular framework-milling machine,

What is a modular framework?

While it is our hope that the owners can keep their machines assembled, we also understand that there are times when it is necessary to disassemble. We all know that the very difficult thing is to move the machine up and down the stairs, unless you remove it, and then move it around a part. In these cases, the precision parts of the ball and slide should be kept intact. From the z-axis saddle, the spindle head is used as an independent casting. Its head can be disassembled and on 6 bolt flanges so that the undamaged z-axis can be guaranteed. Remove the column from the base by removing the four bolts and several wires. A crane that can be used to lift the whole machine is also included in this column, or when it is not bolted.

There are four holes in the hole that are included in this base, and it is easy to lift the fork of the machine with a forklift when passing through these holes.

What is the principal axis?

A large number of low-cost tools and accessories have been caused by the popularity of the fpc1 manual milling machine. “Something caught in a feather pen” may be the title of one of the subcategories. Now, the industry standard is “3-3/8” of the bridge’s diameter. Although there is no independent motion pen for fpc1 now, it has a very good center on the main shaft, which is the main shaft nose, which is just 3-3/8 inches in size. We can see that most of these things that are sandwiched on the bridge are going to be clamped on fpc2. PCNC 1100 incorporates a cartridge style spindle. Instead, a design that plugs the main shaft bearing directly into the head iron is now used by us, and the main shaft bearing is installed on a lathe as our choice.
