Before Buying an Air Impact Wrench What You Should Know

Posted on by

Have there ever been times and instances where you or your family member had to build, construct, or even repair something around your home or office, or even do some work on your car, but you just did not have the right and appropriate tools to get the job done? Do you still use a normal, manual winding wrench to loosen or tighten those loose nuts and bolts?

 

With the power and science of modern technology nowadays, you, your family members, or even your fellow work-mates need not trouble yourselves with the manual and tedious labor of winding wrenches, for there is the air impact wrench! The air impact wrench is also known as an air wrench, air gun, torque gun, or windy gun.

 

This automated power tool brings high torque productivity while applying the least amount of effort by the user. This is done by accumulating energy in a rotating collection, then abruptly and rapidly distributing to the output shaft.

 

There are some points to consider however, when using, and more importantly, buying an air impact wrench. Probably the most touched upon issue and concern when purchasing an air wrench is whether or not the impact wrench you are getting, is the not only suitable to your specific needs, but also for the optimal output of the tool in general.

 

The best and most effective way to get the best impact wrench possible is by checking the brands and models of these wrenches.

 

Some other concerns and matters to consider before buying air impact wrenches are:

 

  • Checking how much torque the air wrench contains
  • The manufacturing and design of the wrench
  • Accumulated and total weight of the wrench itself
  • Air compressor size
  • Size drive of the air wrench
  • Budget to purchase the actual wrench

 

These points, though seemingly common and surely considered before purchasing the actual air wrench by the prospective consumers, are some of the most essential issues which are overlooked by the buyers themselves. Taking these points into consideration when looking to buy an air wrench will help you to make the right choice.

 

Buying the best wrench for your needs will undoubtedly save you not only time, or money, but ultimately you will have the satisfaction of having purchased the best tool out there for you. Be sure to keep these tips in mind, and you will definitely and certainly become the proud owner of an air impact wrench that will get the job done.

How to Use a Double Flaring Tool

Posted on by

One of the specialty tools that everybody who does his own auto repair should own is a double flaring tool. With this tool it’s possible to do a professional looking job with brake line or transmission cooling line replacement. Without this tool this is a very difficult job because it’s almost impossible to find the correct length steel line. A double flare is the best sealing and strongest way to flare a tubing end.

Double Flaring Tool FT-10A

Double Flaring Tool FT-10A

 

  1. Use a tubing cutter and cut the tubing to the desired length. Remove any burrs on the cut end of the tube. Slide the tubing nut on the tube, hex end first.

 

  1. Loosen the wing nuts and insert the tube in the appropriate opening of the tubing clamp. Place the correct sized adapter upside down beside the protruding end of the tube. Allow the end of the tubing to protrude from the tube to match the thickness of the large part of the adapter. Tighten the wing nuts tightly. Keep the halves of the tool parallel to each other as you tighten.

 

  1. Turn the adapter over, coat with a small amount of brake fluid and insert into the tube.

 

  1. Place the flaring tool on the tubing clamp, making sure the screw point is centered on the adapter and the flaring tool is locked on the tubing clamp. Turn the screw clockwise until the adapter bottoms out of the tubing clamp. Final tightening is easier if you clamp the tool in a vise if you have one.

 

  1. Loosen the screw and remove the adapter. The tubing end should have a bubble look at this point.

 

  1. Position the flaring tool with the point entering the tubing end and centered. Turn the screw clockwise and tighten until the cone is bottomed out completely.

 

  1. Remove the flaring tool and inspect the tubing end. The flare should be even all around with no cracks or gaps. Remove the tubing from the clamp.

 

Warning!!!

 

Always carefully check the new flare for cracks. Do not use if any cracks are found.

How to Use a Tool and Cutter Grinder

Posted on by

Usage of Tool Grinding Machine

A tool and cutter grinder is used to sharpen the edges of tools that have gone dull. The tool grinding machine is not a toy and takes special care and training in order to operate correctly. The tool and cutter grinder is also a rather large machine found in machine shops. It is recommended to take your tools to a professional to grind and sharpen them. The following article will explain how a professional operates a tool grinding machine.

 

4 Steps to Correctly Use Tool and Cutter Grinder

Step 1 – Prime the Machine

It is always a good idea to turn the tool and cutter grinder on to warm it up. A cold grinder will create rough cuts while a warm or hot grinder disc will produce the best result. Allow the tool grinding machine to run for several minutes before taking tool to the grinding disc.

 

Step 2 – Safety Precautions

Just looking at the tool grinding machine suggests a medieval torture device. There is a lot of moving parts, guides and rails to worry about as well as the grinding disc itself. Always wear heavy work gloves when using the machine. You also need to wear safety goggles. The grinding disc is typically abrasive and made with diamonds. When grinder begins to sharpen the tool it can cause small fragments of the tool, the disc or sparks to fly toward your face. Getting any of these superheated fragments in your eye can be very dangerous.

 

Step 3 – Examine the Tool

Not all tools are made the same and it is important to examine the tool you are about to use the tool grinding machine on. You are looking for the angle of the tool, including which way the blade is curved, how the edges are cut and the contact points. This is incredibly important because to properly use the tool and cutter grinder you need to know what direction the tool needs to go. If you fail to do this, you can severely damage the tool you are trying to bring back to life.

 

Step 4 – Using the Tool Grinding Machine

Double check all of your safety areas and examine your clearance. The kind of tool you are using will determine what the settings need to be. For this information you should always consult the instruction manual that came with the machine you have access to. Not every tool grinding machine is the same when it comes to this. Turn the machine on and keep a safe distance from the grinding disc. Remember the curvature of the tool you are sharpening and place it against the grinding disc at the appropriate angle. A knife, for example, would be approximately 45 degrees. Use short movements and firm pressure until you are satisfied it is sharp.

Tell You 5 Tips to Find the Right Bicycle Shoes

Posted on by

The right bicycle shoes will offer you comfort while unlocking your performance potential

 

There are many factors to consider when deciding for new bicycle shoes. In this article, I’m going to give you five tips about what to look out for when choosing the right bicycle shoes.

 

Step #1: Finding The Right Length

Bicycle shoes are not running shoes! In contrast to choosing a running or even walking shoe you do not need extra room in your bicycle shoes. There is no rolling motion of the foot in cycling. You can easily test if the length of your bicycle shoe is appropriate. Just take out the original insole of the shoe you are interested in buying and step on the insole.

 

The shoe’s length is ideal, if you have three to five millimeters from the front of your big toe to the upper end of the insole. Make sure that your heel is located right at the lower end of the insole when you carry out this test!

 

Step #2: Checking The Width

 

Now that you found the right length you should not compromise on the width! The front region of the foot is the widest part of the foot and very sensitive in cycling as this is where the transfer of power from foot to pedal happens. There should not be any unnecessary pressure or space on the sides of the foot.

 

Step #3: The Fastening System

 

Moreover, you should take a good look at your shoes fastening system. Buckles and Velcro should not exert any additional pressure. When fastening your shoe the top material of the bicycle shoe should never fold, otherwise this could apply extra pressure points onto your foot. The form of the shoe is likely to suit to your foot if the fastening system is in a middle position when closing the shoe.

 

Step #4: Heel Support

 

A good cycling shoe fit provides a secure anchor for your heel. It should never slip, nor there any extra pressure or pain while walking.

 

Ask a second person to help you to check if the shoe has a good hold for your heel. This person should press the closed shoe to the floor. Now you have to try to raise the heel. If you manage to raise the heel fully or partly out of the shoe, the shoe is not supporting your heel accurately.

 

Step #5: Your Personal Impression

 

Finally: Your bicycle shoes should feel completely comfortable. If you feel that the fit is not perfect ask your dealer if there are any alternative brands or fits that would suit your requirements. Apply the four steps as explained above again when trying other shoes.

The Way of Choosing the Right Surface Grinder

Posted on by

The surface grinder you need will depend largely on the material that needs grinding. For instance, if any metal surface needs grinding, the grinding wheel should be made of a highly abrasive material, and it should have numerous cutting niches embedded in it. On the other hand, for grinding a wooden surface, what you need is a lesser abrasive wheel.

 

The Types of Surface Grinder

 

There are two basic types of surface grinders, and they are:

 

  • The Planer-type
  • The Rotary-type

 

In the Planer-type, the grinding wheel remains stationary, while the worktable moves in a back-and-forth motion. This movement is controlled either manually or through some hydraulic drive system. These grinders are selected when overall grinding is required once the machine component has left the foundry.

 

In the Rotary type, the grinding wheel rotates, as does the circular worktable. These rotary surface grinders are selected when the precision machine parts require grinding, before being fitted into its housing. In both the surface grinder types, the safety hazards are well taken care of, and because of this, accidents rarely happen.

 

Things to do After a Surface Grinding Job Is Over

 

After a surface grinding job is over, the entire work station should be cleared of debris. If the work was done on a wooden material, the saw dust may be supplied to those who make composite boards, while the shavings from the metal surface can be sent to steel mills for melting.

 

However, what matters most is the safe clean-up of the work area, as otherwise, someone might get injured from carelessly thrown bits of metal shavings. Also, the surface grinder needs attention after each operation. It should be checked for any flying debris that blocks its air vents or any damage caused to the moving parts.

 

TONG YI Machinery Inc. is the outstanding rotary surface grinder manufacturer in Taiwan. If you need more information about kinds of surface grinding machines, welcome to visit their website and feel free to send inquiry or contact with them.

Technologies of Proximity Card Reader

Posted on by

Passive Proximity Readers

 

Nearly all building access cards based on proximity are passive. There are roughly 125 million cards used for accessing secured buildings today.

 

Passive technology implies there is no battery or power source required in the card. The proximity reader constantly transmits a low level fixed RF signal that transmits energy to the card. When the card is held at a certain distance from the reader, the RF signal is absorbed by a small coil inside the card and powers the card’s chip which contains a unique identification code. Once powered, the card transmits the code to the reader.

 

The advantages of proximity over other technologies are numerous: no moving parts, no mechanical wear, no slots, no read heads to maintain. The reader can be concealed inside walls or special enclosures and, even when the reader is surface mounted, it has no openings to jam or tamper. The card is the most secure and practically impossible to duplicate. Cards can usually be read through a purse or wallet and through most other nonmetallic materials. Card and reader orientation is not critical.

 

Reading ranges depend primarily on the reader. The larger the reading range, the larger the reader’s concealed antenna and hence, the size of the reader. There is a great variety of proximity readers designed for different environments including vandal-resistant mullion mount, smaller decor style and integrated keypad/reader units.

 

Active Proximity Readers

 

Active proximity technology implies there is a battery within the card. Since the card has power the range is greatly expanded (3-15 feet vs. 1-5 inches). The RF signal is low level (<1mw) but the frequency used is much higher. Applications tend to be uniquely applied, although recently the application in computer access control is more prevalent.

 

Orientation of the card and reader become important. Since the RF frequency is much higher several other effects may be noticed such as exact distance due to the fact that the signal bounces off of other object.

 

Active technology is useful where a hands-free (as opposed to contactless) data exchange is required. Since the range is much longer, it is generally not very practical for door access (except gated parking lots) since walking past the door may unlock the room. The typical application is to detect the presence of a person at a computer and allow access without intervention. Equally important is to automatically lock the computer when a person steps away.

 

Read range is adjustable between 3 to 15 feet.

 

Active cards are generally thicker (1/5 inch) as a result of the replaceable battery requirement

 

Presence Detectors

 

Sonar technology is a relatively new entrant as a tool for security with PCs.

 

In computer security there are two primary components to consider:

 

  1. Unlocking the ‘locked’ workstation, and
  2. Locking the workstation after the logon user leaves the station.

 

The first component generally gets the most attention and array of solutions while the second is generally handled by a time-out screen saver or company mandated policy. Both solutions for ‘2’ above are fraught with exposure issues.

 

The use of sonar technology is a means for detecting the presence or absence of an individual, and performing a specific operation when there is a change. It is important to understand there is no real identification of the user performed with this technology.

 

When a user steps away from an authorized session, the sonar device can detect this occurrence and send the appropriate keystrokes to secure the workstation (log off or lock). This improves solutions associated with policy since the device never forgets to lock. It is also a great improvement over a time-out in that this occurs immediately as opposed to a parameter set by the minute(s).

 

Likewise when the user steps up to a locked workstation, the appropriate keystrokes can be set to call up the logon dialog.

 

This technology can be a great aid for other forms of authentication such as biometrics.

 

Pongee Industries Co., Ltd. is the company of specializing in proximity reader, writer, and programmer. They also provide kinds of high quality access controllers for customers to select. Need more information, welcome to visit the Pongee’s website and feel free to contact with them.

Recycling Baler – Why Do You Need One?

Posted on by

Recycling balers are one of the most useful recycling equipment designed in the recent time. As cardboard is extensively used for packaging, a large amount it comes as waste in landfills. Recycling balers help conserve the environment by crushing the cardboard and compacting large amounts into a single are Cardboard Balers which is easy to transport. Cardboard balers are basically equipment in which cardboard is fed. The press installed within the balers helps to compress the cardboard. The compressed bales are tied off before it is released. Two types of balers are largely used – horizontal cardboard baler and vertical cardboard baler.

 

Why Cardboard Balers are rising in popularity?

 

Cardboard balers are becoming hugely popular these days as it not only helps conserve environment but also help companies save a huge amount of money. Commercial establishments that are increasingly making use of recycling balers include retail outlets, restaurants, office, convenient stores, warehouses, and pharmacies. Discussed here are some of the major advantages of a cardboard baler.

 

  • Follow rules and avoid fines

    – To conserve the environment, in many countries Governments have set up rules and regulation for companies regarding waste disposal. It is suggested that the producers of cardboard’s should be responsible for the reprocessing and recycling of cardboards. A fine is imposed on companies who fail to follow such rules. In this regard, cardboard baler helps companies abide by the rules and avoid fines.

 

  • Help economize on waste disposal

    – Through the use of recycling balers, the recyclable material is compacted significantly. Companies thereby save on the cost of hauling the recyclables. Besides, if a company does not have a recycling facility of its own and decides to sell the recyclables to a recycler, it again stands to make money.

 

  • Help reduce storage needs

    – As the cardboard’s are compacted through the use of balers, they’ll occupy less space. This means companies would not need to allocate a large amount of space for keeping the baled material. This not only helps companies economize on space, which is a valuable resource but also help safeguard the life of workers through efficient material management.

 

  • Helps reduce guilt

    – Environment is everybody’s concern. Throwing a large amount of material produces guilt in the minds of sensitive human beings. However, by making use of recycling equipment such as cardboard balers, people experience a feel good factor as they get a feeling that they too are doing their small bit towards environment conservation.
