Rotary Thread Inspection Tool

Patent No. 7661196
The patented Rotary Thread Inspection Tool accurately inspects internal screw threads for functional size and depth faster and easier than conventional methods. The unique Rotary Thread Inspection Tool safely checks internal threads while eliminating operator arm and hand fatigue and repetitive motion injuries. The instrument features a portable and ergonomic design engineered for industrial applications. The unit is supplied with high performance rechargeable NIMH “quick change" batteries that provide long lasting hours of operation. It also includes a patented depth control feature with automatic reversal.
Safely Inspect Parts
Out of Tolerance parts are instantly recognized. If the thread is undersized, damaged, not deep enough, or has foreign matter in the thread the gage will stop advancing into the threaded hole. This prevents damage to the part and excessive wear to the thread gage. To remove the gage, simply press the reverse button.
Eliminates Repetitive Motion Injury
The power driven gage eliminates all operator wrist motion, arm stress, hand fatigue, and repetitive motion injuries. The Rotary Thread Inspection Tool is ergonomically designed and light weight.
Flexibility
The Rotary Thread Inspection Tool accepts both standard and custom size thread taper lock style plug gages. Changing gage sizes is fast and easy. The tool accommodates a size range from #8 (.164) up to ¾". Other sizes can be priced upon request.
Depth Control
The Rotary Thread Inspection Tool includes a patented depth control feature that allows for the setting of a specified length or depth for the gage to travel before automatically reversing and exiting the threaded part.
Instant feedback
The Rotary Thread Inspection Tool features an “accepted" green light which indicates when the specified depth is reached before automatically reversing the gage out of the threaded part.
Power Source
The Rotary Thread Inspection Tool is powered by a special 9v Lithium rechargeable battery with a rating of 550 mAh. The battery powers the tool for up to 4 hours under normal use. The battery recharge time is 2-3 hours using the supplied charging station which charges 2 batteries at a time. The complete kit is supplied with 3 batteries for continuous use.

Calipers: Ideal For Measurments On The Go
George Schuetz,  Mahr Federal Inc.
http://www.mahrfederal.com/

Although it has been around for a long time, the caliper is still an extremely versatile and useful tool for making a wide range of distance measurements (both ODs and IDs).  While micrometers are more accurate, they have a limited measurement range (typically several inches). The caliper, on the other hand, can span from two inches to four feet, depending on the length of the scale.  External measurements are made by closing the jaws over the piece to be measured, while internal measurements are made by opening up the inside diameter contacts.
Three Types
There are three different types of caliper which may be found today in a machinist's tool chest.
Vernier.  The vernier caliper was the original design and is still the most rugged.  Graduated much like a micrometer, it requires the alignment of an etched scale on the vernier plate with an equally spaced scale running the length of the tool's handle.  Skillful alignment of the tool and interpretation of the reading is necessary to achieve the measurement tool's stated accuracy.
Dial.  A dial caliper is the second generation caliper.  Similar to the construction of the vernier caliper, this style replaces the vernier scale with a dial indicator.  The indicator is fixed to the moveable jaw and engaged with toothed rack on the body of the unit.  The dial, which is typically balanced (i.e., can move in either plus or minus directions from zero), may be graduated in either inch or metric units.
The dial caliper is a dual purpose tool for making either direct or comparative measurements.  To make a comparison, first measure the reference dimension and set the dial indicator to zero then measure the compared dimension.  The indicator will show how much the compared dimension varies from the original (plus or minus).
Another useful feature of the dial caliper are jaws which slide past each other to allow contact points or depth rod extensions to fit into narrow openings for small ID measurements.
Digital.  In the last 20 years, the digital caliper has made its way onto the shop floor.  The latest designs provide many numerous electronic features which make the device easier to use, but add little in the way of cost.  These include: larger digital displays, easy switching between inch and metric units on the readout, tolerance indications, digital output to electronic data collection systems, waterproofing for harsh shop environments, zero setting anywhere along the caliper's range, and retention of the zero setting even when the caliper is turned off.  With no moving parts in the readout, the digital caliper is exceptionally durable, standing up to some of the toughest manufacturing environments.
Concerns
Care and Respect.  Like any measurement tool, the caliper must be treated with care and respect.  Don't use it for purposes for which it was never intended (such as prying things apart).  Wipe it clean after using, and don't throw it on the workbench.  For dial calipers, be particularly wary of dirt which can accumulate on the rack, throwing measurements off and ultimately damaging the indicator.  Store a caliper in its case.  If it's going to be there for a while, apply a thin coat of oil to the jaws to inhibit corrosion.
Wear and Calibration.  Check the caliper often for wear, as well as burrs and scratches on the jaws and contacting surfaces.  A simple way to do this is to pass a master disc along the jaws while inspecting for wear or taper.  Like any measurement tool, a caliper should be calibrated at least once a year or more often when use is heavy or there are multiple users of the same instrument.
Proper "Feel".  While the caliper is a versatile tool, it is not one of the most precise.  Skill is required for positioning the tool and interpreting the measurement result.  As the user develops his "feel" for the tool, his measurement results become more consistent.
While the digital caliper may take some of the guess work out of reading the measured value, it still requires skill on the part of the user to apply the tool properly to the dimension being measured.  The jaws of the caliper must be square or perpendicular to the part.  They are held firmly against the part, but not to the point of deflecting them.  The part should be kept as close as possible to the frame of the measurement tool.
Knowing its Limits.  The rule of ten says that a measurement tool should have ten times more resolution than the tolerance of the dimension.  Calipers typically read in 0.001" units. So if the tolerance is tighter than ±0.005", a micrometer (or some other higher accuracy tool) is the way to go.

The humble caliper is a surprisingly versatile tool for a wide range of general purpose distance measurements.  With a little skill, you can make a fast direct measurement or comparison in seconds and move on quickly to your next important task.

Gage Care and Replacement Pins Just a Phone Call Away!!!!

50TH ANNIVERSARY  1960 - 2010 Gage Care and Replacement Pins Just a Phone Call Away!!!!     July, 2010 - Vol 1, Issue 2

Greetings! I'd like to share some tips with you on how to care for your gages. Gages are a valuable tool for your business, and the investment made should be properly cared for to maximize your ROI.  With a proper care they can provide long service on the production floor.  Gage Handling   Proper handling of gages will extend their useful life.  Avoid handling the gage surface because oils from your skin can rust gages.  If you must handle the gage surface wipe the gage clean and reapply a light coating of oil to protect the surface when finished using the gage.  Once rusted the gage in most cases is ruined!

Proper Use   A few simple rules when using the gages. Clean the parts before gaging to remove dirt, coolant, or metal chips. Do not force the gage, use light pressure Inspect for nicks or burrs before each use, this will eliminate innaccurate results. When using plug gages for go no-go inspection the go member should fit into the work piece to indicate to the operator that the component meets the correct specifications.  The no-go member should not fit into the work piece.  If it does this indicates to the operator that the component has been machined incorrectly and is out of specification. Plug And Pin Gages:  What They Can Do     What Plug Gages Are: Used to inspect holes and or slots for pass or fail conditions only Used as masters for setting micrometers, verniers, or calipers. Check locations, and distance between holes What Plug Gages Are Not:  Resizing tools, or reamers Debur tools, or clean out tools Used to measure the exact or actual size

Gaging Tips

Air Rings and Air Forks 

 

We have talked many times in this column about the advantages air gaging brings to the manufacturing process, especially on the shop floor. In addition to their speed, ease of use and ability to automatically clean part surfaces before measuring, air gages are also capable of measuring to tighter tolerances than mechanical gages. At their very best, mechanical gages can measure down to 50 millionths, but that requires extreme care. Air gages handle 50 millionths with ease, and some will measure to a resolution of 5 millionths.  When most people think of air gaging, they think of plugs. But a number of air ring and air fork styles provide the same benefits and some additional ones as well. An air ring is the opposite of an air plug, and is primarily used to measure ODs. Air rings look quite simple—a steel ring with a pair of jets at a particular location—but there is a lot of engineering built into them.
One trick is in calculating the size of the ring in order to achieve a good balance of clearance between the part and the opening in the ring. Too much clearance and your readout will start showing centralizing error. This happens when the part is shifted slightly in the tool and the air ring measures a chord rather than the diameter. Too little clearance and the indicator's range gets limited—or even worse—a geometry error can prevent the operator from inserting the part into the air tool.

 Air Snaps Improve Shop Floor Measurement Performance  

Mechanical snap gages have been the gage of choice for measuring OD's as parts are being machined. They are an easy to use, fast and reliable method to check the OD of the part while in the machine. But today the tolerances on many OD’s are shrinking. What was once 0.002” is now 0.001” or even 0.0005” on diameters 4” or larger.
Once these tolerances are specified the mechanical snap starts to meet it limits. Because of the mechanical limits and resolutions of the readouts they just don’t have the capabilities to meet GR&R performance required. This is where the Air Snap takes this measurement process to a new level.
Because the air snap is made to the size to be measured with no moving parts, the design is far superior for the application. Special configurations allow for placing the jets close to shoulders or multiple measurements in a single gage. A combination of high performance and versatility make an Air Snap the gage that will improve your measurement process.
