Slewing rings have been widely used for the last four decades. Ideally, a slewing ring is a type of component used in machines. It is commonly used in construction machinery such as cranes and excavators, and military machinery. It is also known as turntable bearing, slew bearing, and slewing bearing. This type of bearing can handle large radial and axial loads.

The slewing ring has parts such as outer ring, spacer, sealing, and inner ring. Depending on the external structure, this type of bearing has types such as external gear type, internal gear type, and non-gear type. For the internal structure, this bearing can be into four-point, double row, crossed roller, and cylindrical roller.

Slewing Ring Features

If you want a bearing solution that is flexible with your applications and handles large loads, slewing ring bearing is the right option. The slewing ring bearing has a high load capacity. In fact, it can handle combined loads, including radial, tilting movement, and axial load.

As far as flexibility is concerned, the slewing ring provides different options you can choose from. Also, this type of bearing is highly customizable. These are some of the features of these bearings:

Location and size of hole patterns vary

It is available with an external or internal gear

Availability of preloading options

Two or single row ball bearing options are available.

If the above features do not suit your application, you can reach out to your bearing supplier to customize them further.

Uses of Slewing Ring

Considering the flexibility and load capacity of the slewing ring, many industries use this type of bearing. For instance, slewing ring bearings are widely used in:

Installation of Slewing Ring

It is advisable to check the surface before you install the slewing ring. Ensure components supporting it has adequate rigidity. Also, the matching surface must be machined to achieve inclination and flatness of required standards. Every set of slewing bearing is marked with “S” that ought to be placed on the non-loading area.

Position your slewing ring radially and then tighten mounting bolts and check rotation of the bearing. Since smooth rotation is important, you need to check the condition of the meshing before you tighten the bolt. Most manufacturers lubricate the ring properly before it is shipped.

After you install the bearing, you need to have it inspected before it leaves the factory. If your application involves high temperatures, you should shorten the cycle of greasing. Moreover, if the bearing is stored for quite long or your machinery has not been in operation, you need to re-grease it.

Selecting Slewing Ring

When choosing the most economical and efficient slewing bearing for your application, you need to consider various factors. For instance, you need to consider the loads that are added, application type, frequency of movements, and torque applied.

Your choice of slewing ring can be based on static and dynamic load ratings. Also, you need to consider applied loads and requirements regarding service life and reliability.

Milling is an important machining and manufacturing technique. Traditional milling machines ought to be operated by trained technicians or engineers. The modern machines utilize computer-numerical control (CNC) technology. CNC milling services offer a lot of advantages over the traditional milling services. That explains why manufacturers and fabricators in the plastic and metal industries are embracing these services.

Key Advantages of CNC Milling Services

Cost-Effective

First, the CNC milling service does not need individual machine operators. Instead, after programming the desired cuts, the machine cuts them automatically. Therefore, one programmer can oversee operations of multiple CNC machines, including grinders, routers, lathes, and more.

This manufacturing technique helps lower the labor costs as it streamlines the process of equipment set up and machining. On the other hand, a conventional milling machine required that operators set the gears manually for desired cuts. CNC milling eliminates such time-consuming processes. This helps reduce the number of employees and work hours they spend on various milling tasks.

Quality Results

Since CNC milling machines are automated, they have a competitive advantage over their conventional counterparts when manufacturing various parts. For instance, it provides higher accuracy and repeatability.

Repeatability is also known as precision, and it is the ability of a machine to make similar cuts continuously. Accuracy of CNC machining service refers to the ability to cut pieces to accepted tolerances. Higher accuracy means that components or parts made will fall within acceptable dimensions or tolerances.

Since CNC milling is controlled by powerful computers, it offers better results that are accurate and precise. Conventional milling service is prone to errors. Moreover, it relies on the skill of the operator. Production of parts that do not fit the intended purpose cost you more.

Improved Safety

CNC milling machines use advanced cutting tools that can cut metal or plastic to the required shape. The cutting tools create potential hazards that can cause accidents and injury to operators of traditional milling machines. Since most milling tasks are repetitive, it is easier for an operator to get bored and tired, resulting in injury if the operator loses focus.

Future Proof

You should note that CNC technology is currently used in different industries. Nevertheless, their applications will keep increasing. That is because CNC milling services supports seamless integration with different design and manufacturing software applications. For instance, integrating CAD-CAM helps improve the productivity of the milling service by over 40%. That is because it allows the design and programming of high-speed tool paths that support machining.

Lots of Applications

With CNC milling service, a wide range of plastic and metal parts can be made. Many industries require consistent, complex, accurate parts. Some of the industries that benefit from this service include aerospace, construction, automotive, metalwork, electronics, transportation, and military. Also, a wide range of materials can be used. Some of the materials used are aluminum, plastic, fiberglass, copper, wood, titanium, steel, brass, and foam.

The truth is that CNC milling services continue to revolutionize different aspects of the manufacturing sector. It is now easier to generate parts within a few hours.

Rapid prototyping is a manufacturing technique used to fabricate physical parts using 3D computer-aided design (CAD). Prototypes are convenient for developers, users, designers, and investors to validate and communicate their ideas. The process involves collaboration among designers, managers, engineers, and end-users.

Rapid Prototyping Benefits

Being a manufacturing process, it has its share of pros and cons. Ideally, this technique reduces development time, reduces risk, improves user involvement, and reduces development costs. The major issue is that it requires skilled labor.

These are some of the advantages of rapid prototyping.  

Quick Testing

With rapid prototyping, designers can iterate and test various design methods and ideas. Also, it allows for the use of intuitive visuals to complement verbal descriptions. Every person involved in the process will have a consistent understanding of important needs.

Time-saving

When designers employ rapid prototyping, they can get feedback quickly, which they can use to improve the final design. Moreover, the process helps minimize changes during product development and improves productivity.

Cost-effective

Experts at Rapid Done argue that when rapid prototyping tests are done at the early stages of product development, you can save a lot of time and cost (Contact RapidDone to know more ). That is because time spent on back-end product architecture is considerably reduced. The prototype can be tested before it is available for development.

Rapid Prototyping Process

Brainstorming

Rapid prototyping starts with brainstorming. It is an effective way of building a profile for your parts and products. In fact, failure is common in the process, and brainstorming allows designers to work on both bad and good ideas in a low-cost, safe manner before investing energy and time into the development of prototypes.

Production of 3D Files

Production of three-dimensional files of the product is necessary. The use of 2D plans is recommended for parts with critical tolerances. Also, project specifications ought to be drawn up. Specifications depend on both technical constraints and the end-use of the product. After creating specifications and 3D files, a rapid prototyping company comes in.

Costing

Every rapid prototyping project is costed by a prototyping company based on the technical features and quantity of parts. Features consist mainly of material, geometry, and finish of a prototype. This step is that it helps determine the feasibility of the project. At this stage, there is room for modification of the parts.

Evaluation

Prototypes are shared with users, designers, and experts to evaluate whether they meet the intended purposes. This stage aims to establish that the final product performs the expected function. If the product is not found to be valid, it is returned to the first step of brainstorming.

The success of any given prototype depends on the prototyping technology used. Each technique has its competitive advantage in terms of speed, material compatibility, development stage, fidelity level, and cost. Rapid prototyping does not have to be limited to a single process. Multiple manufacturing processes can be used to assemble a prototype. The following are the common rapid prototyping technologies used:

CNC machining

Investment casting

Binder jetting

Stereolithography

Fused deposition modeling

Vacuum casting

Aramid fibres are some of the strongest and the best heat-resistant types of threads in the market. These fibre strength can get attributed to the high proportion of the chemical bond that exists in the structure of these fibres. They are synthetic types of threads that got introduced into the market in the early 1960s. Traditionally, the fibres were used in aerospace and military industry for a wide range of applications. Currently, their applications have increased, and one of the many applications of the fibres is in the manufacture of aramid packing material.

For many components and products made from metal, including cars and utensils, rust is a devastating condition. In rainy climates such as those of the United Kingdom and Brazil, metal surfaces rot and crumble away quite quickly when water is absently left to collect in any crevice present on the metal surface. The traditional ways of dealing with rust on metal components and products included grinding, cutting, and selective choice fabrication. However, the efficient application of a quality laser rust removal tool has been proven to be much more efficient and faster than all the other techniques combined. Laser rust removal works magnificently to clean up metal parts quickly. Let’s focus on the advantages of laser rust removal.

How the laser rust removal and cleaning works

In general, the procedures involved in removing contaminants of various types such as oil, rust, and oxides from steel surfaces by utilizing laser technology are collectively called laser cleaning. Thus, to clean rust from a metal surface, lasers use ablation, where any surface that absorbs the laser beam light appropriately enough is heated to a plasma. For example, a carbon dioxide-based laser can generate up to 1000 Watts of power that can be focused on a spotless than one millimeter squared.

The metal surface that absorbs the laser rust removal tool’s wavelength is heated extremely fast, exposing the clean metal surface beneath. This cleaner metal surface then begins to reflect the remaining laser beams off the metal surface, preventing them from eating away at the iron underneath.

Advantages of laser rust removal

• The technology applied in laser rust removal tools is reliable and fast

Lasers enable the efficient and rapid cleaning of metal parts of various shapes by eliminating rust accumulated on their surfaces.

• Laser rust removal involves low consumable cost and low maintenance costs for the laser rust removal tools. Such tools and systems are so low-maintenance they have almost no consumable costs.

• Laser rust removal tools consume very little energy, and the new fiber laser cleaning techniques feature even lower electricity consumption rates.

• Improved productivity and versatility – the fact is, laser rust removal tools and associated cleaning systems are superior alternatives to chemical and manual rust cleaning methods since the trajectories of the laser beams can be quickly altered using software inputs.  

How laser rust removal is possible

• It is always possible to remove contaminant material in a particular way – considering the presence of an ablation threshold for each material. Cleaners can distinguish between two or more layers when trying to remove an unwanted layer from a surface.
• Every material (including metals) has an ablation layer. In this instance, laser ablation occurs when a layer of rust deposited on a metal surface is easily removed by applying a laser beam from a laser rust removal tool.
• Laser beams are environmentally-friendly and consumable-free – the laser beams are only focused on the surface to vaporize the rust layer, meaning that the process has no consumables.

Conclusion

Laser cleaning is a fantastic new technology that is set to overcome many of the previous challenges that existed in the process of rust removal from metal surfaces. Laser rust removal tools are fast, clean, and efficient for metal cleaning.

Surgical masks, also known as medical face masks, are very popular at this time with the continued spread of Coronavirus. The virus has led to the introduction of the masks to the public. Before this, the masks were only used by professional health care workers. The role of the mask was solely to prevent infections during medical processes like surgeries. However, countries like China and Japan, among others that are highly populated, have recorded the use of masks in public places. Also, traditionally, face masks were manufactured manually. However, currently, most manufacturers use face mask making machines for the process. In this post, we look at the cost of face mask production.

Factors that Affect the Cost of Face Mask Production

The Features of the mask

The first element that influences the cost of manufacturing face masks is physical features. They include;

• Material- The material from which the mask is made greatly influences the cost of production. For instance, all-natural ingredients are harder to find and more costly. Therefore, making a mask from scratch using all-natural materials is more expensive than the latter. Materials like plastic are the most commonly used. However, the type of plastic used differs, and this affects the cost of the manufacturing process. For instance, some ingredients have to be imported from different parts of the country. This increases the cost of production.

• Color- The color of the mask also affects the cost of manufacturing. For instance, sometimes, to achieve the desired color, manufacturers are forced to use coloring chemicals. These chemicals have to be acquired at a cost. The coloring process also requires money.

• Scent- Face masks are worn on the mouth and nose. For this reason, they are mostly scentless. However, the materials used in the manufacturing process normally have peculiar scents. Therefore, in the manufacturing process, the scent has to be eliminated. This may warrant the use of certain chemicals in a process that needs financial resources.

The process of manufacturing

The manufacturing process is also a significant influencer. The process requires both time and money. There are different steps in the process. The first process is carried out by chemists or engineers. The human resource is one of the major factors that influence the cost of production. For a face mask manufacturing company, hiring freelance chemists and engineers is less costly than hiring a staff to work within the company.

The next step of the process usually involves using automated production machines. Using machines in the manufacture are more beneficial than manual manufacturing. The cost of running the machines is also a factor. The cost of electricity and maintenance differs from one machine to the other.  

Quantity of production

Contrary to common belief, the higher the number of production means, the lower the cost of production. The materials used in production will be more if the quantity is high. However, the cost of running the machines, time spent, and human resources are reduced when production is done in mass than the latter.

Conclusion

In this current state of the world, face mask manufacturing companies have more work than ever. However, not all face masks are efficient against bacteria and viruses because of their design and material.
