7 Different Types of Milling Machines

Milling machines come in various types with a variety of functions based on certain standard specifications. Some of the most commonly used machines are the following: column, turret, C-frame, horizontal, bed type, planer-style, and tracer controlled.

A milling machine is a tool in the metal industry that has numerous functions. Each machine has a cutter that operates at a various range of speed so you can form the required shape. With its adjustable spped feature, each milling machine can be regulated for a more precise cut. The machine is capable of handling multiple tasks such as carving, threading, milling, drilling, and cutting. There are several several types of milling machines, each with varying functions based on standard criteria. Manufacturers often name the different machines according to the kind of control, number of axis present, orientation of the spindle, size of the tool, its purpose, and source of power. While there are several varieties of milling machines available today, they essentially serve the same functions but use different terminologies. Below is the list of seven types of milling machines.

Column

This is the most common milling machine, which has 5 basic components, They are the work table, saddle, head, knee, and over arm. Considered as the simplest machine type, its cutting device is vertically suspended to allow drilling of metals. This is typically used when creating car parts because it is small and handy.

Turret

The turret is also known as the Bridgeport-type and can be repositioned anytime you want making this machine very functional. Its versatility makes it more practical since a variety of products can be made in addition to car parts.

C-frame

Because it is sturdier than a turret, this type is popular in industrial settings. It comes with a hydraulic motor, which makes it very powerful.

Horizontal

This machine runs parallel to the ground. The table from which the object to be worked on is placed moves sideways while the cutting device goes up and down.

Bed type

The worktable is located on the bed itself, instead of being paced on top, its usual position. The knee part of the machine is omitted to allow movement in a longitudinal direction.

Planer-style

This machine type is basically the same as the bed mill. However, the planner-style includes cutters and heads that allow for a wider range of milling actions.

Tracer controlled

This type of machine has the ability to reproduce parts based on a master model. Most of the industrial sectors, especially the automotive industry, choose this type of machine because it make production and specialization of machine parts easier. With the vast classifications of milling machines, you need to choose the one you need according to how you intend to use it. However if you find it difficult to decide, do not hesitate to seek the help of a specialist who can help you select the one that will give you maximum benefits.

How Is the Blister Packaging Machine Useful?

Blister packaging is a form of plastic packaging and is used in the pharmaceutical as well as the consumer goods industry. The blister packaging machine is increasingly used in these areas and there are many types of blister packaging that are available in the market.

Pharmaceutical Industry

In the pharmaceutical industry, the blister packaging machine is used as unit-dose packaging. Tablets, lozenges, and capsules are packed using the unit-dose packaging system. These blister packs not only provide a barrier but also help in protecting the shelf life of these products. This type of packaging offers a certain amount of tamper resistance. In the US, all physician samples and over-the-counter drugs use blister packaging. The blister pack is also better known as the Push-Through-Pack in some certain countries across the world. Blister packaging ensures some degree of authenticity and integrity of the product.

How They Work?

The blister packs use the form-fill-seal process, where there are rolls of flat films or sheets that have pharmaceutical products filled in them. The packs are then sealed using the same machine which is termed as blisterline. This is later dispatched from the pharmaceutical companies to the distributors. This is one way of ensuring the safety and authenticity of the product.

Consumer Goods

The blister packaging machine is also used extensively in the consumer goods industry. This type of packaging is used in many consumer goods like toys, pens, electrical and electronic goods, hardware, and many other products. This type of packaging is very useful as the consumer can clearly see what is inside and look at the product without having to open it or tamper with it. It is sealed at the manufacturing unit and hence remains tamperproof. A vacuum formed plastic shell is placed around the mold and hence the product can snugly fit into the packaging. This consists of the paperboard card on one side and the pre-formed plastic on the other side.

The other form of packaging is known as the clamshell, which is a more secure packaging system. This is especially useful in the packaging of electronic items. This consists of 2 pre-formed plastic sheets that are fused together at the edges. This is designed in such a way to discourage tampering and this is an excellent way to package an item and prevent duplication. You will need a sharp object such as a knife to open this packaging.

Medical Blister Trays

These differ from the pharmaceutical blister packs as they are not the push-through packs. Here, a thicker plastic is used and this forms a solid tray. There is a peel open feature and these are generally used to package medical devices that are used in the hospitals.

The blister packaging machine has many uses in all these areas of manufacturing and it ensures that the products are tamper-proof to some extent. There are various methods that are used during the manufacturing such as cold forming and thermoforming. Even the materials used in blister packaging can vary.

The Importance Of Industrial Centrifuges

A centrifuge is a machine used for fluid/particle separation. Looking for a used centrifuge? These machines rely on the use of centrifugal force, generating several hundreds or thousands of times earth’s gravity. They are used for separating solids from liquids, liquid-liquid separation, and liquid-liquid-solid separation.

A centrifuge is a piece of equipment, generally driven by an electric motor, though older models were hand spun, that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis. Industrial centrifuges can be classified into two main types, filtering and sedimentation. Filtering centrifuges use centrifugal force to pass a liquid through a filtration media, such as a screen or cloth while solids are captured by the filtering media. Sedimentation centrifuges use centrifugal force to separate solids from liquids, as well as two liquids with different specific properties. Sedimentation types include decanter, disk-stack, solid-bowl basket and tubular bowl centrifuges.

Filtering types deal with perforate basket, pusher, and peeler types.

Centrifuges are not mass produced like pumps, motors, cars, refrigerators, therefore the cost associated with purchase of centrifuges for sale are normally higher when compared to other types of process equipment. It is estimated there are close to two hundred specific applications industrial centrifuges are used for. Centrifuges are not a ‘one size fits all’ type of machine. All industrial centrifuges are originally manufactured for a specific application to be used in.

The process is one of the most important and widely applied research techniques in biochemistry, cellular and molecular biology, and in medicine. Current research and clinical applications rely on isolation of cells, sub cellular organelles, and macromolecules, often in high yields. The machine uses g-force to isolate suspended particles from their surrounding medium on either a batch or a continuous-flow basis. Applications are many and may include sedimentation of cells and viruses, separation of sub cellular organelles, and isolation of macromolecules such as DNA, RNA, proteins, or lipids

Special purpose centrifuges can be design as per your unique industrial applications. Industrial centrifuges are widely used in all type of industries to separate solid from liquid. In industries, the mixture of liquid and solid needs to be separated. The centrifuge makes it possible very easily with the help of centrifugal force. Simple centrifuges are used in chemistry, biology, and biochemistry for isolating and separating suspensions. They vary widely in speed and capacity. They usually comprise a rotor containing two, four, six, or many more numbered wells within which the samples, contained in centrifuge tubes, may be placed.

Cleaning of Ball Screw Bearings

Ball screws are mainly formed by screw, nut, ball, holder, wipers, and the return tube. The ball assembly acts as the nut while the threaded shaft is the screw. They have many features such as high precision, long life, and low pollution. These products can be widely used in industrial machinery such as precision machine tools, industrial machinery, electronic machinery, and transport machinery, etc.

Ball screw bearing plays a very important role in many different applications. Ball screws offer an efficient means of converting rotary motion to linear motion by the use of a number of bearing balls that transfer the load between the nut and screw. Bearing maintenance is always the focus because the failure of products can lead to many serious problems. Many methods can be adopted to do the maintenance. Among them, the cleaning is one of the simplest ways.

Now, let us learn something about the cleaning of these bearings. Although ball screws often have some sort of shielding or casing, even the best protected screw sometimes gets contaminated with debris or dust. Thus, the proper cleaning becomes quite necessary.

Before cleaning the them, you should first remove the assembly from the machine. Make sure that the atmosphere is always clean. After that, you should hold the it under running water, repeatedly rotating the nut mechanism along the length of the screw. And place it in a small container filled with an aqueous or organic cleaning agent. There are still many steps to follow.

Then, you should remove the it from the cleaning agent and dry it with a rag. Rotate the nut along the length of the screw and listen for debris in the bearings. After this, you should remove the nut from the screw if you are not sure about whether it has been cleaned thoroughly or not. Next, you can remove bearings from the nut with a pair of tweezers. Be careful not to damage, drop or lose the bearings during removal. Clean the individual bearings and all other screw components with industrial degreaser. Dry the components completely with a rag.

After you complete all the above mentioned steps, the cleaning of the ball screw bearing has been done. Then you many just replace the bearings in the nut mechanism, and reassemble the ball screw.

Using different industrial machines are really great but before buying them there are certain things that you must look at. With the use of the different threading machine you can ensure the safety of the organization and at the end, you will even save some money from it.

Ensure The Ductility And Strength Of Metals With Cupping Machines

In today’s era of modernization, metals are used in different production verticals to manufacture various domestic and industrial products. The numerous fields where metals are used include automobiles, industrial machines, electrical devices, and so forth. These fields in which metals are used are very critical where there is no room for defects and require high-quality of products that can ensure efficiency, high performance with the best level of safety. In these fields, there is no space for flaws as the errors in such fields can lead to various accidents which will create horrible consequences for the users and affect the life of the users. This let the manufacturers of metal products to be extra conscious regarding the quality of the products.

The manufacturers need to ensure that the highest quality of the products they produce with the use of best quality of testing procedures and testing devices. With the help of testing instruments, the producers can determine various properties of the metals like chemical composition, the physical strength that predict the behavior as per some given conditions. This helps the manufacturers in deciding different factors that are related to the safety of the product as well as the safety of the users and offer the best quality to the clients. To assure the quality of the metal products, it is necessary to commence some quality tests at the different level of production like raw material procurement, production process and end product. Ignoring the quality of the product will directly degrade the quality of the products.

One of the most popular tests which are performed on the metal goods is the cupping test. The test is conducted on the metals substrates that are duly painted or coated. The test is performed to test the ductility of the metals and to test the quality of the coated. The test sample is placed on the machine to create shearing forces on the very small area of the specimens that create a small cup on the side of the test specimen. The load sensor present on the indenture records the amount of shearing force applied to the metal plate. In this manner, the maximum value of force is calculated which is applied to the metals without cracking the material.

The test is also used to verify the ductility and the elasticity of the paints that are used on the metal surfaces. The cup shape formed in the metal products at the time of the test is analyzed to determine the cracks that are developed on the surface of the paints. Hence, it is used to verify the quality of the paints and metals both.

Industrial Mixer: Essential Mixing and Blending Equipment

Industrial mixer is a modern machine that mixes different materials and components to create the desired paste, solution, or mixture. It is used in popular industries involving chemicals, food, and drugs. Vital parts of this equipment are blades of different grades that produce mixtures of different levels of homogeneity.

Modern mixers perform industrial and chemical processes; like dry blending, paste mixing of viscous products, and emulsifying and homogenizing purposes. When it comes to scale, they are available from laboratory level to mass-production capacity.

Advantages of using Industrial Mixers

1. Work at the precise temperature and pressure

A major advantage of these industrial devices is that they mix and produce solutions while attaining the necessary temperature and pressure. Correct temperature is attained because of the presence of built-in heating systems.

2. Possess built-in features and options

Important options and features are also present in modern mixers, such as electric or pneumatic systems, CIP, spray nozzles, PLC systems. They are equipped with either hydraulic or electronic mechanism that ensures smooth start-and-stop operation.

3. Assure continuous mixing operation

Especially in the case of the latest models, mixing operations are done smoothly and continuously. Typical mixing equipment that produces smooth and consistent mixture is the Continuous Processor. With this machine, all ingredients are correctly measured and metered, with the desired solution being produced at the end of the process.

Most industries opt for machines that perform continuous mixing mainly for the following reasons; low consumption of electricity, greater control of operation, wider versatility, among many others. Another widely used continuous mixer is the twin-screw processor. This equipment has the capacity to deal with high mixture viscosity.

Different types of industrial mixers

1. Planetary mixer

Planetary type is used in mixing various commercial and industrial products such as food items, pharmaceutical products, adhesives, plastic, and pigments. Industries that require mixture of viscous-paste consistency achieved within a vacuum condition utilize this type of mixer. Paste production capacity varies, ranging from less than a pint to a maximum of 750 gallons.

2. Static mixer

This type of mixer, as the name implies, does not move. It possesses no movable components. The static type utilizes a specific chemical property of materials that’s necessary for mixing without the use of any pressure or force. Basically, as fluids are mixed in the machine, the right amount of air pressure is sealed within the unit. In effect, it creates a contained system that produces specific amount of pressure necessary in an environment. Such air pressure forces components and fluids to move and mix inside the machine.

Static mixers are used in gas refining and energy production, creation of fibers, blending of different chemical fluids, and proper management and disposal of wastewater materials.

3. High Viscosity Paste Mixer

A common industrial mixer is the high-viscosity paste mixer, which effectively combines solid and liquid materials. The end-product can be as little as a hundred thousand centipoise or as voluminous as a few million centipoise. Two important processes that involve this machine are vacuum and jacket, both of which are necessary steps in removing existing air and controlling the overall temperature of the mixture.
