3 Reasons Why Calibration of Your Measuring Instrument is Important

In contemporary times, we are surrounded by technology. Our entire world revolves around it, without which none of our work seems to be possible. Accuracy becomes the most important factor when it comes to using machines as the reliability of production totally depends on the advanced technology of the machines. For this purpose, it becomes indispensable to look for the specifications of the measuring tools used to check the precision and accuracy.

Numerous precision measuring tools are used to ensure that the machines serve us with the correct data. These instruments need to be accurate enough on which one can rely on taking decisions and performing tasks. Due to this reason, calibration of measuring tools are done to assure that the measurements are appropriate and deliver correct information.

What is Calibration?

A process of juxtapositioning between a standard measurement and one which is used for measuring is termed as calibration. It configures an instrument, providing assurance that the result delivered is appropriate.

When it comes to checking the precision of instrument through calibration, it should be 10 times the accuracy of the measuring device that is being compared with standard one. If there arises a case where measurements don’t meet expectation to that of the criteria, then with the help of calibration it is adjusted for achieving particular specifications.

Why is Calibration Important?

It serves us as a guarantee that tool which is used for the measurement is meticulous. For better understanding, we brought you few more reasons that would evidently explain its paramount value.

  • No Manufacturing Errors, No Cost

Sometimes, large manufacturing industries may face some flaws in the production. Consequently, the cost of it rises. Though defects would be small, their costs prove to be the high burden on the manufacturers. It would not only be expensive in the form of resources, but also as a waste of time. It can be avoided through calibration of measuring instrument that verifies if it delivers an appropriate result or not.

Calibrating tools and gauges will evidently reduce the risk for attaining any possibility of production defects. But, ensure that the sensors which are used for its monitoring are appropriate in this process. However, laying hands on the correct calibrating tools would serve your purpose in the best way and it can be done by buying it from a trustworthy supplier such as Penn Tool Co. For gaining detailed information, you can explore penntoolco.com and get your desired products.

  • Safety

It goes without saying that when every functioning of the measuring instruments is verified under the process of calibration, it keeps all the processes safe. All the devices and machines which are used to produce products ensures its safety through this process.Certification

  • Certification

The accuracy of measuring device deteriorate with time fleets. And this wear and tear of the machine

The accuracy of measuring device deteriorate with time fleets. And this wear and tear of the machine are occurred due to several factors affecting it. Therefore, it becomes imperative to look for the safety of it, which can be made possible by calibrating measuring tools proficiently. However, it can be said that certification of the machine is maintained through calibration.

Now since you are introduced to the paramount importance of calibrating instruments, it is upon you whether or not to consider these points in your manufacturing process. Besides, it is for sure that this verification process won’t harm the production in any way.

Micrometer: Its Working Principle, Parts, Use And Precautions

Mitutoyo micrometers


A micrometer is used for measurements that require greater precision than a caliper. Though micrometers gives superior precision, it can only measure a very small length. It consists of a calibrated screw that which when rotates helps in giving an accurate measurement.

Reading measurements in a micrometer is not at all a difficult task. With a little care and precaution, one can learn to take the measurements easily. If you want a buy a good micrometer, Mitutoyo micrometers are really good.

Principle of Operation

The basic principle of operation of a micrometer is as follows:

  1. The amount of axial movement of a screw that is made accurately can be measured by the amount of rotational movement of it. This is because the pitch of the screw is constant.
  2. The measurement made due to the rotational movement is some amplified form of the actual axial movement of the screw.


A micrometer has the following parts:

  • Frame: It is the C-shaped body that holds the anvil and the barrel together. This frame is heavy and thick which makes it difficult to strain under mechanical and thermal stresses.
  • Anvil: It is the part that rests on one side of the frame. Spindle moves towards the anvil when in order to hold the object and take the measurement.
  • Sleeves/barrel: The stationary cylindrical component that the frame holds on the other side of the anvil.
  • Lock nut/thimble lock: The lever which is used to tighten the movement of the spindle so that it doesn’t move while taking the measurement.
  • Screw: It is the main component on which the micrometer works and is hidden from the sight.
  • Spindle: The cylindrical component which moves when you rotate the thimble. This touches the object which is to be measured and holds it tight.
  • Thimble: It is the component which is turned by thumbs and which makes the spindle movement.
  • Ratchet stop: The device which is at the end of the instrument and is responsible for exerting only allowable pressure to the object and not more than that.

Care and proper use of a micrometer

Before you rotate the thimble or the ratchet knob, unlock the locking lever. Make sure to clean the measuring faces with the help of a clean cloth before you begin taking measurements. As you begin measuring, start rotating the ratchet knob and not the thimble. The ratchet knob will ensure you do not over tighten the thimble as that will not only give an erroneous reading but can damage the instrument too.

It is also advisable that you do not keep the instrument in the Sun for long. The horizontal line on the sleeve should be aligned to zero when the when the micrometer is at minimum reading. In case it does not happen, the micrometer will be needed to calibrated. For calibration, each device comes with a half-moon adjusting wrench.

Remember to use the thimble lock while micrometer is still holding the object. If you do not do this, the spindle might move a little while taking the reading or taking the object off from the micrometer. Write the measurement when the lock is on and if you haven’t written it and taken the object out, redo the measurement.

Micrometer finds its use in almost all manufacturing industries. They can also be mounted on a bedways of the lathe or similar machine tools to make the measurements accurate and easy.

11 Types Of Machines Used In Metal Working Industries

Metalworking industries employ a wide range of machine tools to create parts that are of a desired shape and size. These machines have evolved over the past hundreds of years and have made it possible to produce not only the most complex shapes but also in a way that involves very less human effort.


There are various techniques used by the fabrication industry that has led to invention and evolution of many machines. Following are the most widely used machines in the metalworking industry:

  1. Lathe Machine: These are the machines that rotate the workpiece to perform various machining operations. Lathes can be used to produce parts that are ferrous, non-ferrous metals, plastics, and wood. They are multipurpose machines that can be used to perform operations like cutting, sanding, knurling, drilling, boring, threading, facing and turning. They come in various sizes, and with a range of accessories.
  2. Milling Machine: It is a machine that uses rotary cutters to remove the undesired material. The workpiece is held tight on the movable worktable and a rotating tool is made to move vertically. The two major operations that a milling machine performs is face milling and peripheral milling.
  3. Grinding Machine: In this machine, an abrasive wheel is made to rotate at relatively high speeds. The rotating wheel provides finishing to the workpiece by removing a very small amount of material along its surface, after which it becomes smooth to touch.
  4. Drilling Machines: These are one of the most common types of machines that we can see around us. They are used for various household repair works too. The tools of this machine are easy to install and replace which makes it really easy to use. They can be used for making a hole in a wide range of materials which not only includes metals but also materials like cement and concrete.
  5. Shaper Machines: It uses a single point cutting tool that moves in a linear motion to perform a cutting operation on a workpiece. It has a simple mechanism and is easy to operate too.
  6. Broaching Machine: It uses a toothed tool or a broach to remove material from the workpiece. There are two types of broaching processes – linear and rotary.
  7. Saw machines: There are three types of saw machines, hacksaw, circular saw and band saw. These machines are used to cut a metal piece into two. It uses a blade which is either rotating or reciprocating to make the cut.
  8. Planer Machine: This machine is very similar to shaper machine and the only difference in this machine is, the cutting tool is stationary and the workpiece is made to move in a linear motion. Generally, these machines are larger than shaper machines.
  9. Shearing Machine: It is a machine that is used for cutting sheet metal. Shearing process does not form chips or any residual material. Other major metal cutting operations that are similar to this are blanking and piercing.
  10. Hobbing Machines: These machines are used for making gears and splines. It is a type of milling machine that uses a special type of cutting tool but is relatively inexpensive and is mostly used to produce spur gears.
  11. Drill Press: It is a more reliable version of a hand-held drill as they have better stability than them. The workbench allows the drills to be made continuously with good accuracy.

These are the most common machines used for metal cutting and shaping operation in metalworking industries. Special purpose machines are also made for performing some specific operations on a specific product. These machines are used for increasing the production rate.

In last couple of decades, many new technologies have come up that involves advanced techniques to produce articles that are not only of complex shapes, but also that produces less amount of waste materials.

Best Micrometers- Top picks for 2017 Best Rated Micrometer Top Picks Micrometer Reviews

Which are the Best Micrometers?  What are the best micrometers to buy? Best Rated Micrometers – Top 10 Picks – Micrometer Reviews

By Michael Elson Vice President Penn Tool Co published on February 26, 2017 in micrometers

This list contains the top brands in precision tools such as Starrett, Mitutoyo, Fowler, SPI, and Igaging and we put the list together trying to find out which is the best micrometer.

Any of the micrometers on the list will do the job for you perfectly well.  However, you want the Best Micrometer for the money.  What you after is a device that will give you accurate readings.  So what makes one micrometer better than the other?  A better question is why is one micrometer more expensive than another one.  I ask this question every time I buy a bottle of wine.  What is it about this bottle for $10.00 that I am missing if I bought a $50.00 bottle.
Basically I ask this question every time I buy anything.  For this article lets stick to best micrometers, but the point has been made that basically on every decision you make you are always asking yourself should I spend more or less money for the item in question.  There are several factors that make one more expensive than the other one.  Factors such as price, quality durability, country of origin, and features. High priced micrometers can last a very long time if they are cared for properly.  Some of the lower priced ones are almost like disposable razors.  You know going in that these will get the job done but may not be your go to best micrometer in your toolbox.  These lower priced models might not be there in a few years.  Lets take a look at Best Micrometers!

1. Mitutoyo 293-340 Digimatic Outside Micrometer, 0-1″ Range, 0.00005″/0.001mm Resolution, IP65, No Output, with Ratchet


Number one on the list may I present to you one of my favorite and most popular micrometers.  The Mitutoyo 293-340.  Back in 1934 the founder of Mitutoyo Yehan Numata started his company with one product in mind.  THE MICROMETER.  Many years have past but Mitutoyo is still making some of highest quality micrometers around.  They have gone digital now and perform like as you would expect something out of Japan to perform.  Think of your favorite Japanese car. Or if you don’t like Japanese cars, you certainly are someone who appreciates craftsmanship and value.  That is what you get with the Mitutoyo 293-340.  Coming in at under $150.00 the micrometer is certainly one of value.  Priced just right.  Not too high and certainly not so low you are thinking this has to be a piece of crap.  No need to protect this in your toolbox.  This micrometer comes standard with a hard plastic case that will protect your measuring device for many years down the road.  With carbide tipped measuring faces can you really go wrong?

To Carol Kopyta’s supervisor August 13, 2009

Dear Madam / Sir,

I have recently had a very good experience dealing with Penn Tool Company’s Customer Service.

I was in need of an Operator’s Manual for a lathe that we purchased from Penn Tool in 2003. I was really did not expect Penn Tool to have this manual as I do not think you currently are marketing this line of lathes.

Your Customer Service person Carol Kopyta handled my request in a most professional and expedient manner. As it turned out she knew the right person to ask, got the information correct and within a very short time had the document mailed to me.

What is particularly impressive is not that Penn actually had a manual but the expedient manner in which Ms. Kopyta handled my request.

In a time and culture where customer service is often times greatly lacking it is heartening to know there are some people who are still conscientious and diligent.

My already high opinion of Penn Tool has been elevated yet higher by Ms. Kopyta’s excellent response to my request.

Keep up the good work. I will look forward to conducting business with Penn Tool in the future.

#How to remove broken taps



Easy was to remove broken Taps

#How to remove broken taps

Step 1:

Remove as much as practical of any uneven broken taps top surface of the tap, creating a reasonably flat surface for the Omegadrill to drill into.

Step 2:

Clamp the part securely. Use as large a diameter Omegadrill as possible to spot the broken taps. Drill at 1,200 to 2,500 RPM on a rigid and stable machine tool such as a machining center or knee mill.

Step 3:

Using the recommended size Omegadrill, drill down through the broken taps. Drill dry or use straight cutting oil – not coolant. Peck the drill and flush chips out frequently with an air blast. Best results are achieved with using light quill hand feed on a knee mill. When reaching the bottom of the broken tap, a slight vibration will be felt. It is best to stop drilling at this point, to minimize any risk of damage to the Omegadrill’s cutting edges.

Step 4:

Using either a scriber, or the picks and pin vise supplied with the Omegadrill set, remove the remnants of the broken tap flutes.
