Types of Drill Bits

Posted on by

Drill bits are equipment or tools that are used in making cylindrical holes. Drill bits can also be referred to as a drilling machine. Drill bits are available in various drill types such as metal drills, gun drills, screw machine drills, core drills, step drills, spade drills, forstner drills, masonry drills, dental or surgical drills, wood bits, twist drills, drill blank taper drills and much more.

 

They are designed to cut while doing a clockwise rotating motion. Several drill bits are coolant fed. They contain a channel or hole for directing the coolant fed near to the cutting edges. The split point drill heads of drill bits are used for chip clearance and for excellent centering. Drill bits can also be used in cutting aluminum, general-purpose metals, brass, copper, bronze, ceramic, and plastic, stainless steel, steel, wood, titanium and hardened materials. Various types of drill bits are designed for different uses.

 

Listed below are some types of Drill Bits:

 

Twist Drill: It drills holes in plastic, metal and wood. This drill is currently produced with a width covering a range from 0.05 millimeters to 100 millimeters while its length is around 1000 millimeters. The most usual twist drill has a tip angle of 118 degrees. This is a proper angle for an extensive array of job. It also has a long series drill for extended length twist drills. It is not advisable to drill deep holes using this twist drill.

 

Diamond Drill Bit: This particular drill is used in the bathroom for updating or remodeling. It is also used in redesigning your kitchen decoration. Furthermore, it is used on ceramic, glass, tile, limestone, stained glass, marble, fiberglass, porcelain, stone, slate and porcelain tile. When using this drill, the main concern is to obtain water at the edge of the drill bit. Drilling fiberglass may be done with or without water but make sure that the fiberglass has ample amount of water just to get the drill wet.

 

Indexable Drill Bit: This provides an excellent performance in making short-hole drillings. Stainless steel is drilled 3x in diameter and only a short-hole must be done.

 

Listed below are some other types of drill bits

 

  • Adjustable Bit:

This is built with a changeable cutter blade to bore holes of various sizes. It is also used for drilling gaps for wiring or piping.

  • Around-the-corner bit:

It is used to cut arched holes that are stretched in corners with a diagonal cutting surface.

  • Auger Bits:

This drill creates drill holes in wooden materials. The drill ends have a screw head so that the bits may be self-fed.

  • Brad-point drill:

This drill looks almost the same as the usual bits but it has sharpened point to make wood drilling a lot easier. This drill has cleaner holes other than spade bits.

  • Counterbore:

The drill allows a screw to be driven under the wood outside. The holes that are drilled may be filled with a plug or wire.

  • Drill Saw Bit:

It is used to cut holes such as wood and metal and can enlarge current holes.

  • Countersink:

A drill that has an angled tip design that forms a “slump” in the screw head.

 

  • Fly cutter:

This one is often used to cut circles in wood and other soft metals. The diameter of circles may be adjusted by changing the cutter blade setting.

  • Hole saw:

It cut holes from one to six centimeters in diameter and has a center bit for directing the cutting blade edge of the saw.

  • Reamer bit:

The tapered bit of reamer may be used on existing holes rather than to enlarge holes.

  • Screw pilot bit:

This beautiful bit is used for drilling body holes. A pilot hole is used along with the countersink.

  • Wire Brushes:

It use to remove rust and to clean up metal and is available either as a wheel or a cup with wire brush.

  • Plastic bit:

This is designed with a tip so as to prevent splintering when drilling plastic. It is important to reduce the speed and slowly drill the other side of the plastic.

  • Plug cutter:

Use this to remove cylindrical shapes from the wood. It covers the screw using a small cylindrical plug.

Fasteners and Fixings: Choosing the Right Self Tapping Screws

Posted on by

Picture this: You are standing in the aisle at the home improvement warehouse, staring at a wide variety of fasteners and fixings. There are hundreds of shapes, sizes, and types to choose from, and you have no idea what you are looking for. All you know is you need a self tapping screw. Frustrated? Yes, you probably are. There is no need to be though. Here are a few helpful hints that will have you navigating the screw section like a pro.

 

What are Self Tapping Screws?

 

Self tapping screws are able to advance into a material as they are turned, meaning a hole will not need to be drilled before these screws are used. There are typically gaps between the threads on the screw, which make it easier for the screw to stay in place and advance into the material. Self tapping screws are generally preferred over nails because there is less of a chance the screw will pop out of the wood in a deck or wall.

 

What are the Main Types of Self Tapping Screws?

 

Many times, the types of screws you decide to use will be determined by the materials you will use the screws with. Here are just a few different types of these specific fasteners and fixings and what materials they may work best with.

 

  • Round Head:

While self tapping screws are generally used with tough materials, if you need to use on for a thin material, a round headed screw may work best. These are the most common types of screws available. Many times, this type of screw is used in combination with a washer.

 

  • Pan Head:

If the material you are working with is heavy duty, you should consider using a pan head. These are oval with a tapered base and work well for tougher materials.

 

  • Flat Head:

For those ‘assemble yourself at home’ types of furniture, you may want to consider using a flat head self tapping screw. These will generally last much longer than the nails and bolts given to you with your home assembly package.

 

  • Phillips Heads:

Are you working with drywall or a wood project? A Phillips head may be the best choice for you. This type of head provides more control and less slippage, which can be helpful if you are working with a type of material that can easily be damaged.

 

  • One Way Heads:

If you are working on a project that needs the security of a type of screw that is tamper proof, a one way head screw may be your best option. These screws require special tools to be used if they are going to be loosened.

 

The wide variety of fasteners and fixings can be confusing for those who don’t understand what they are looking for and what their specific project requires. In addition to these types of screw heads, self tapping screws also come in an assortment of materials, including metal, plastic, and wood. Choose the one that fits your project the best.

Introduction of Engine Lathes

Posted on by

An engine lathe is a flat shaped piece of work holding, which is most frequently used to turn metal manually. By turning the metal and by using particular cutting devices, the engine lathe is competent of forming the metal into exact shapes. As its name goes, the engine lathe is over and over again used to make metal pieces for use in an engine, whether it could be for an automobile, a tractor, a boat, or as well for any other motorized vehicle or machine.

 

Even though people may use the engine lathe initially for spinning sheet metals, it is as well used for drilling, making square blocks, and for shaping shafts. Candle cup dies, copy burner nozzles, foundry pattern core boxes, and other prints are products an engine lathe could produce. Most modern tools were shaped with the assistance of an engine lathe. In addition, those who own an engine lathe could create their own devices with the machine. For these reasons, the engine lathe is regularly referred as a work holding machine.

 

Further features of an engine lathe consist of gears, a carriage, a tailstock, and a stepped pulley that are generally used for different kinds of spindle speeds. The workings in the engine lathe are used to control the carriage. Simultaneously, the carriage bolsters of the cutting tools. The tailstock is commonly used to hold up the hole-drilling process, which takes place in the spindle.

 

Engine lathes were in style in the 19th and 20th centuries at blacksmith shops and are yet far and wide used today. There have, on the other hand, been a few amendments to the engine lathe over the following years. In the unique engine lathe, the carriage might catch all the dust and dirt. When this mixed with the oil in the engine, it would shape up a grinding motion as the carriage moved back and forth while turning and for shaping the metal. The steady grinding finally wore the machine down and made it useless.

 

Today, the cart on an engine lathe is self-oiling further on and the rear. The carriage on the engine lathe has as well been improved, and is built to defend the machine from the remnants of the jobs it performs.

Plastic Injection Molding and Its Advantages

Posted on by

Product identification plays an extremely important role in communicating a product’s position and brand in the marketplace. Plastic nameplates can convey messages, brand, classifications, description, schematics, warnings, instructions and many other types of product information.

 

Plastic injection molded nameplates help to identify your products and help them stand out in the crowd. Before we go further, let’s take a quick look at the plastic injection molding process.

 

The Plastic Injection Molding Process

 

The plastic injection molding process is not a complicated one. Molding processes of this sort involving metals go back many years, and basic principles have not changed, just the methods and materials.

 

Of course, you have seen what the finished product looks are. You’ve seen them more times than you may be aware of. You’ve seen them as car emblems, appliance and industrial nameplates, custom plastic nameplates, recreational product nameplates, point-of-purchase, plaques and signs. They fill the world around you, but do you know how are they made?

 

The process begins with a plastic pellet made of a composite of organic and inorganic polymers, plus additives to aid in the melting process. This small pellet is tossed into a hopper with thousands of other pellets. This begins the journey from pellet to product. The next step is preparing the plastic.

 

The pellets are released onto the threads of a giant rotating screw. As the pellets travel along, they are heated to melting temperatures, somewhere around 400 degrees Fahrenheit. Of course, the higher quality the plastic is the higher temperature it takes to melt it. The pellets are rolled along the screw because the process also requires friction and force. The screw provides both as the pellets roll along its surface and crash into each other.

 

Now that all three requirements are met, friction, force and heat, the pellets begin to liquefy and the next step of filling begins. The screw continues to guide the liquid plastic along its threads to a valve. Under high pressure the valve forces the plastic into a custom designed mold – made of heat resistant metals – until every cavity is filled. Once this is achieved the mold goes into the holding phase. The filling and holding phases are crucial steps in the plastic injection molding process. Their execution will determine the quality of the finished product. The metals we use for the mold insure that the last piece made carries the same qualities as the first.

 

The Next Step

 

The pressure on the mold is maintained while the molten plastic cools to a solid state. This stage could take a few minutes as the mold absorbs the heat from the melted plastic, and in turn is cooled by coolant that encircles it. While the part is cooling, the screw returns to its original position, collecting more pellets from the hopper. The product is then ejected from the mold and moves to its secondary processes such as decoration, sub assembly, or shipment. The mold closes, and the process begins all over again.

 

Advantages of the Plastic Injection Molding

 

There are several important advantages of utilizing injection-molded plastic:

 

  1. The plastic injection molding allows complex and intricate shapes to be manufactured. Shapes that would be too difficult or costly to manufacture with different processes.
  2. The plastic injection molding allows for a high volume of plastic nameplates and custom plastic signs to be manufactured at the same time with the same mold and quality.
  3. The metal molds have a long life. When you come back for a future order, the mold will be ready and your next order will be identical to your first. In addition, their initial cost is low too.
  4. The plastic nameplates can be decorated in a variety of ways such as textures in the mold, metallic foil, ink, UV protection, and more.

 

Other Advantages

 

Plastic Injection Molding allows manufacturers to produce custom plastic nameplates and components that would be too costly to make as intricately as required, by utilizing traditional machining methods. Injection-molded plastics also saves you time and money by allowing high numbers of pieces of the component to be made at the same time, with each copy identical to the one before it. This process also reduces labor costs by minimizing the need for manual labor from employees. Finally, there is virtually no wasted material. Any unused or left over plastic can be re-cycled to be reused in the process

Advantages of Food Steamers

Posted on by

Healthy eating is the basic for leading a healthy life. Healthy eating not only means eating nutritious food that is good for health, it is much more than that. The food we eat should be cooked in a healthy way. Steaming food in steamer is the most nutritious method of cooking. When food is cooked in the food steamer, the food particles never come in contact with water. So the nutrients in the food are retained. Similarly the aromatic composition and cellular structure of food tissue are retained when cooked in food steamer. In food steamer the cooking takes place in convection process. The food is wrapped in watery steam, so it allows any type of item to stay tender.

 

Coming to the next point, what type of food can be cooked using steamer? It can be used to cook vegetables, fish, dumplings, chicken and many more. When vegetables are steamed using food steamer, the vitamin content and flavonoids are not lost. Similarly, while cooking fish, the essential Omega 3 fatty acids, flavors and nutrient content are retained. When fish is fried or grilled in high temperature, it may lose its nutrient value. Taking these into consideration, it is sure that using food steamer is the best choice.

 

To promote healthy lifestyle, you need to make basic changes in your food habits. Eating steamed vegetables and other steamed item is certainly good for health when compared to other type of cooked food. The vitamins and minerals are retained in the food when it is cooked in food steamers. For instance when you cook brown rice in an ordinary vessel, the valuable vitamins in the brown rice, particularly vitamin B1 is lost. But when the same is cooked in Kitchen steamer the vitamins are retained, thus helping you in eating healthy food.

 

If you are a health conscious person, then investing in steamer is a good choice. Because the food is neither overcooked nor undercooked in steamer as it generally happens with other kitchen appliance.

Office Chair Casters and Safety

Posted on by

The wheels that office chairs have are also called office chair casters. They often go unnoticed in the office. One employee rolls over to the fax machine. Another goes to his desk and back in front of her computer. People use them without regard and this continues until the casters are not working as it should be.

 

Office chair casters are awesome when they are in good condition. However, they can be a problem when they are not. Accidents do happen when employees sit and move around their office chairs that have broken or poorly installed casters. To combat this, there is a need to learn more about them, specifically in how to replace damaged casters and in selecting the right type of caster for the office. Studying about basic safety information about chair casters is also important.

 

Changing office chair casters is a bit easy. This is because most wheels are mounted on steel support posts that are attached to the base. When only the wheel is damaged, the steel posts are likely to still be where it is and they can be taken out using pliers or a screwdriver blade. So one only needs to push the replacement office chair casters tightly to its place. Replacement casters should certainly be available from the chair’s supplier and are usually inexpensive. So it is good to try calling up the manufacturer of your office chair. However, if the base is also broken it is necessary to get a new one though it a little uncomfortable especially when the chair is a bit old. Buying a new chair in this case may be a better option.

 

Moving on to finding the correct office chair casters for your chair, it is important to match the casters to the floor surface of the office. This is since choosing the wrong types of casters will make it, on one hand, difficult for the chair to move. On the other hand, they can also make your chair skid everywhere. So what are the common kinds of casters and where are they usually used? Most office chairs have casters that are used on carpeted floors so it’s okay if your office has carpets. If the office, however, has a floor surface that is smooth as in tiled, cemented and hardwood floors, it is best to use polypropylene or rubber casters because of their superior grip on these types of surfaces. Chair makers generally furnish the customer with the appropriate casters.

 

And then it all goes back to some of the basic office chair safety precautions. Always follow instructions on assembling a chair even if it’s not easy. Always do regular check-up on the components of a chair. Refrain from rocking office chairs with casters as they only work at certain angles.

 

Office chair casters are simple. They are things that people overlook until they are causing problems. Yet what is only needed to keep them in check is a little more attention.

 

Fuh Shyan chair casters are made of PP or PU, which are stronger and durable. Here we manufacture various types of chair casters for different office chairs. We are the first choice of office chair wheels manufacturer to you, and welcome to contact us for more spec of our office chair part series!

Introduction to the Hydraulic Control Valve

Posted on by

The prosperity of the modern industry has been doing great favors to our daily life and the industrial process. Actually, there comes a great variety of the valve types to meet the increasing requirements. Among the various types, the hydraulic control valve has been playing an important role in regulating the water.

 

The hydraulic control valve is the valve which is used to control the pressure. Generally speaking, it consists of a main valve and the matching accessories like the catheter, pilot valve, needle valve, ball valve and the pressure gauge. As to achieve some specified specifications, the manufacturers would produce various types of the hydraulic control valve according to the different operating functions and working conditions. For example, there are many further divided species. They are remote control floating ball valve, reducing valve, check valve, flow control valve and pump control valve and so on. Now, the details for two specified valve classified by the structure are introduced in the following.

 

Although with different structures, the two types works under the same principle which means the pressure difference. The one is called as the diaphragm type and the other one is called as the piston type. The pilot valve would lead the diaphragm or the piston to work. Then, the force gained by the water would start to adjust the device of the main valve to be totally opened or closed or under regulation. Or it can be said in details as follows. When the water above the diaphragm or the piston is poured into the lower area, the pressure below would be greater than that of the upper area. At this moment, the device of the main valve is pushed to be totally open. On the contrary, the device would be under the state of totally closed. And it the pressure is in medium scale, the valve is regulating the flow. No matter what, if the all parts cooperate together well, the valve would be able to perform under the pressure difference.

 

As we all know that the water project is generally important on all fields. Therefore, the hydraulic control valves continue to bring benefits. And in fact, there are many trials to improve the performance of this kind of the valve in order to service the future water project better.

About RJ11 Connector Jacks

Posted on by

RJ is the short form of Registered Jack. It is a physical network interface that is used to connect telecommunications or data equipment to a communications provider. They standard and form are regulated by the FCC. Each registered jack has a particular design and is named according to its design. There are many different types of registered jacks and the Connector is one Registered Jack type.

 

It is commonly used because it can be found in most homes and office. All single line (POTS) handset jacks here make use of the RJ11 Connector. The RJ11 connector has six positions, but out of the six only two is used or at the most four. The wiring can be in the form of Unshielded Twisted Pair or the Untwisted Flat-Satin cable. There are many manufactures of connectors.

 

Often there are comparisons made between the Connector and the RJ45. It is to be noted that the RJ45 serves the purpose of making connections between various systems in a network, while the RJ11 can make used to make connections between telephone systems. A unique aspect about the connector is that since only two out of the six positions in the jack are used, it can be wired to a 6P2C modular jack through this is something that is rarely done.

 

The powered variation of the RJ11 Connector has its two and five pins carrying 24-volt, DC power. The power supply to the pins comes from a plugged transformer. Since mostly two out of the six positions in the jack are used, the remaining positions are free. These extra connectors can be used for other purposes. For example, they can be used like an ‘anti-tinkle’ circuit that stops a pulse phone from ringing other extension bells.

 

Sun Jun Electronics Inc. founded in 1984, specializes in RJ Connector (RJ45 & RJ11) series products of developing and manufacturing, has experience more than 25 years.
