A bearing refers to a mechanical part of an industrial object. This may be a standard definition of the term, but do you really know what the device does? This tool is, in fact, fundamental to the machine sector such that it is often referred to as bread and butter. Bearings are used in different machine types. But since they work well in the shadows, professionals interested in delving into the industry probably hear of the term but have no clue of what exactly it means. For that reason, this write-up will explain the basics of bearings with a focus on turntable bearing. It also highlights their functions.

The Pain Point

No matter how hard you try to prevent it from happening, things break. There is often a chance that a product will fail. The same applies to turntable bearings.

However, that does not imply that you cannot prevent the issues from arising because then, it would result in major downtime.

This blog post is a detailed guide to some of the foremost factors that may contribute to bearing failure and how possible it would be to prevent the issues from arising.

When you learn more about the potential problems, you will be able to prevent them as well. This means that you can get the most out of your bearings. This should simplify your applications.

Up to 90 percent of failures in bearing are caused by lack of lubrication. It includes insufficient lubrication and the application of substandard lubricants or high temperatures that can degrade the lubricant.

What Should You Look for?

 There are a few things you should look for in your device in the case of a bearing failure. One of them is a discolored rolling element like blue or brown and a rolling-element track coupled with overheating and excessive tear and wear in the device’s bearing.

a. Fixing The Problem

You should use the recommended lubricant type and avoid grease loss while following the appropriate lubrication intervals.

b. Contamination

The contamination of a device is caused by different foreign substances that get into the lubricant of the bearing and cleaning solutions. They are such as dirt, dust, and steel chips hailing from contaminated areas and dirty tools.

c. Things to Look For

You should watch out for denting of elements and raceways, which cause vibration. To fix this, clean the work areas and fixtures to reduce the chances of contamination.

d. Improper Mounting

All too often, bearings need to be mounted using a press fit on the ring.

What to look for

What to Look for there are multiple conditions that can contribute to denting and cracked rings. They include mounting bearings on the shafts through applying pressure blows on the outer surface.

Fixing It

Using a manual, follow the appropriate mounting instructions while providing training to ensure that all workers are well versed with the differences between an appropriately and inappropriately installed mounting.

Final Thoughts

By arming yourself with the problems that may cause a bearing failure besides the signs you should watch out for, you have taken a rather huge step toward cutting down machine failures.

Rapid tooling has made everything easy and possible, especially enabling prototype, pre-production as well as full production tooling all being fabricated within greatly reduced time frames. Ideally, rapid tooling techniques are Rapid Prototyping that involves the RP-generated objects into the tool-making process.

There’re two major categories of rapid tooling with one category involving an indirect approach that uses RP master patterns in producing a mold. The other category is the direct approach, whereby the RP machine builds actual core as well as cavity mold inserts.

The most common rapid tooling types in prototyping include;

3D Printing

This is arguably the most popular method across the globe. In fact, it’s so mainstream that amateur level users even are capable of doing it at home. 3D printing method seems to be evolving without stopping any time soon, and it’s becoming even cheaper with the highest quality.

With the 3D method, molds are being created very fast and very cheap to make. Moreover, the devices that are used have an excellent range of handling intricate designs as well as angles. However, much is required to be done on the method of tolerances. Also, one can’t get several productions runs from the molds that are created with the 3D printing method.

Laser Sintering

Metal is not used only for rapid tooling via the traditional machining, but also can be used in creating a plastic injection mold, whereby metal particles can be fused together to make a solvent; a process known as “sintering.”

Sintering in rapid tooling is performed by spraying powdered metal to a laser beam that allows drawing of the shape of the mold. Several metals can be used in the process, including titanium, stainless steel, or cobalt chromium.

It’s one of the most precise, clean, and powerful manufacturing processes. Moreover, making the mold with the process allows you to have complete control over the transfers of heat, ejection times as well as clamping pressures. Also, printing cooling lines on your mold in making production cycles become faster and efficient.

Traditional Machining

Rapid tooling can also be done through traditional machining. For instance, when it was first introduced, those companies that were building molds via traditional methods such as machining steel or aluminum started to increase speed to ensure that they also compete.

Rapid tooling was eventually used for every tool which could be quickly built, even those that could be created with traditional methods.

However, the most downside of the traditional rapid tooling method is geometry. For instance, if one looks to cut a cavity shape, then there’s a limitation by the cutter used, meaning that one can’t use a round cutter to cut a square corner.

Nevertheless, it should always be kept in mind that because one is capable of creating a mold using rapid tooling doesn’t guarantee to save a lot of time. The mold creation process is usually faster when compared with the traditional machining of aluminum or steel. However, it requires some finishing touches, which usually can slow the process down once you create the mold.

Rapid prototyping is the process of modifying machine parts using 3D computer-aided design. Due to a rise in the use of technology, a lot of innovations are taking place, and prototyping is one of them. https://industrial-statistics.com/effective-rapid-prototyping-projects/ shares additional insight.

Types of Rapid Prototyping

In the creation of a prototype, there are different types used. Below are the most common types;

1. CNC Machining Rapid Prototyping
It is one of the most critical methods. This procedure doesn’t have specified materials to use since it can create parts from any content.

2. Stereolithography (SLA)
For this type, 3D printing is used. It is used in the manufacture of plastic prototypes. It is used in the production of components that get produced within a short period.No matter the shape; Stereolithography can create accurate prototypes. Prototypes made with Stereolithography can be machined since they are durable.

3. Selective Laser Sintering (SLS)
It is the most common additive manufacturing method.  It is used in metal and plastic prototyping. In the creation process of a substantial part, 3D printing is used to heat powdered material used.

4. Fused Deposition Modelling (FDM)
It can be found in most 3D non-industrial desktop printers. It is cheap and easy to use, making it the best for low-volume production. Thermoplastic filaments get melted before a computer deposition program is used to lay them layer by layer. With time, the process has improved, making the best for product development.

5. Selective Laser Melting (SLM)
It is also known as powder bed infusion. It is a process used in the production of durable and complex parts. The parts produced using this process are used in industries such as medical, aerospace, automotive, and defense.

Electric contactors are switches that function in a way that is similar to relays. They have numerous applications in different industries. For instance, contactors are frequently used to give focal control of large lighting establishments, especially in office and retail buildings. They are applied in such a way because they don’t consume a lot of power. Thus, to lessen power utilization in the contactor coils, latching contactors with two working coils are used. This means that one coil, quickly energizes, shuts the force circuit contacts, which are then precisely held shut; the subsequent curl opens the contacts. Battery contactors are also used in magnetic starters. This is a gadget intended to give the capacity to electric engines. It incorporates a contactor as a fundamental segment, while additionally giving force cutoff, under-voltage, and over-load assurance.

Components of a contactor

A contactor is made up of the following parts:

a. Contacts- the contacts are the current-conveying some portion of the contactor. The contacts are made up of the power contacts, assistant contacts, and contact springs.

b. The electromagnet- this part is the main driving force that is located to close the contacts.

c. The enclosure- this is the part in which the electromagnet and the contact is hosted. This part is usually made of protecting materials like Bakelite, Nylon 6, and thermosetting plastics to ensure and protect the contacts and to give some proportion of security against the workforce contacting the contacts. Open-outline contactors may have a further enclosure to ensure against dust, oil, blast risks, and climate.

d. Magnetic blowouts- these parts use magnetic coils to extend and move the circular electric segment. These especially come in handy in DC circuits. Air conditioning curves have times of low current, during which the bend can be quenched without any difficulty. However, DC circular segments have nonstop high current, so blowing them out requires the bend to be extended farther than an AC circular segment or arc of a similar current.

e. Economizer circuit – in some cases, an economizer circuit is likewise introduced to decrease the amount of power that is required to keep a contactor shut. An assistant contact lessens the coil current after the contactor closes. Normally, more power is used to close the contactor than that which keeps it closed initially. Such a circuit can spare a generous measure of power and permit the curl that is energized to remain cooler. Economizer circuits are almost consistently applied on direct-current contactor coils as well as on large exchanging current contactor coils.

Conclusion

A conventional contactor will have a coil input. The coil input might be driven by either an AC or DC depending on the construction of the contactor. Universal coils that are driven by AC just as DC are likewise accessible in the market today. The coils can be energized at a similar voltage as the engine the contactor is controlling. It can also be independently controlled with a lower coil voltage more qualified to control by programmable controllers and lower-voltage pilot gadgets. Certain contactors have a series of loops that are connected to the engine circuit.

If you are like most folks, then you probably don’t know the difference between shot blasting and sandblasting. Even though these are two similar terms, they are different process whose goal is the same – to treat metal surfaces.

What separates the two processes is the treatment media. Sandblasting relies on compressed air to shoot sand against the surface, whereas shot blasting uses centrifugal force to shoot some other type of abrasive media over the surface.

Nowadays, sandblasting is declining as a surface treatment process because sand has certain properties that complicate the process. On the other hand, shot blasting uses abrasive media that is easier to handle. That includes various metals, plastics, glass, and various minerals. Sometimes, shot blasting uses organic materials such as walnut shells and cobs. 

To have a better overview of the two processes we need to analyze them separately. 

Sandblasting

Generally speaking, sandblasting is a somewhat less invasive and smoother abrasion process. But then again, that is determined by the intensity of the compressed air pressure, as well as the characteristics of the abrasive media. 

Because the process of sandblasting is smoother, and if softer media are used, it is possible to treat very sensitive surfaces. That way, the risk of accidental damage is significantly lower. 

That makes sandblasting ideal for treating connectors and various electronic fixtures. In terms of media options aluminum oxide is a popular option as it can cut through almost any surface contamination while at the same time preserving the integrity of the undersurface. On the other hand, silicon carbide media is a popular option when more abrasion is needed.

Sandblasting uses the following equipment: air blast rooms, air blast tumble equipment, wet blast equipment, blast and recovery systems, bulk blasting systems, blast pressure & suction cabinets, and portable blasting stations.

Shot Blasting

Shotblasting is best suitable when it is needed to treat heavy and thick surfaces such as truck hubs and metal hulls. Sometimes sandblasting takes too much time and is too gentle. That’s when shot blasting comes to save the day and treat whatever surface stands on its way, regardless of how dense or contaminated it is. 

Shot blast machinery includes the following components: Tumble blast equipment, swing table blast wheels, spinner hangers, cylinder blasters, hanger blast equipment, and table blasters. 

Choosing Shot Blasting Vs Sand Blasting

There is no wrong or right choice as it is the character of the job that determines which method will be best suitable. The best answer is to leave it to the finishing experts.

But, generally speaking, sandblasting is ideal for smaller, more delicate surfaces in which speed is a major requirement. Then there is the economical angle in which for smaller projects, sandblasting tends to be the more affordable option.

In any other regard, shot blasting is the superior option. Many surfaces can be treated only with shot blasting. Because of that, shot blasting is the preferred method in many industries. Then there is the fact that shot blasting is way more environment friendly and unlike sandblasting, it doesn’t present any significant danger to its operators.

Aluminum does not magnetize and forms alloys with nearly alloy metals it an excellent choice for the production of many electrical parts such as switches, power lines, cables, etc.  

Food/Pharmaceutical

Aluminum doesn’t react with most organic substances; this makes CNC aluminum the most preferred technology in making parts used in various equipment and machines in the food and pharmaceutical industry.

Machine parts used in these sectors must meet precise specifications needed in these sectors. This has increased the popularity of CNC aluminum machining all over the globe. Machine parts required in the food and pharmaceutical industry vary in shape, size, and density. CNC machining allows the production of parts that meet the set requirements.

The USDA and FDA are among the regulatory bodies that set conditions for components used in machines in the food and pharmaceutical sectors. CNC aluminum machining is used in making components such as centrifugal pumps. Actuators, metering extruders, depositing rolls, pump boxes, knife shafts, etc.

Cryogenics Machining

Aluminum maintains its mechanical properties at sub-zero temperatures. This makes it the choice metal for cryogenic applications; cryogenic machining involves the use of liquid nitrogen as a machining coolant instead of the typical mist or flood coolants. This technology has gained considerable popularity in high-performance machining.

Aluminum-lithium alloy is the best material for aircraft fuselages because of its corrosion resistance and strength-to-weight ratio. It’s also suitable for aircraft parts, spline shafts, wings, dowel pins, gears, and electronic hardware.

Final Thoughts

As one of the easily machinable metal, aluminum is processed quickly and efficiently via CNC machining. Aluminum CNC machining applies to many sectors, including automotive, aerospace, automation, medical and food industries, to produce different parts required for machines and equipment used in these sectors. Aluminum is used in making sports equipment like sports whistles and baseball bats.
