Optical Comparator with 2-D Processing

Optical Comparators are inspection machines that project magnified images of parts onto a glass screen using illumination sources, lenses and mirrors for the primary purpose of making 2-D measurements.

Using an Optical Comparator allows the technician to see the part from the magnified form up to 50 times the actual size.

Very small radii and other featured can be easily checked when enlarged on the screen. Including thread gages, thread standards and specialized tooling.

This saves time, money and will ensure your gages meet specific federal guidelines.

Finding the right Calibration Labratory

                    

The criteria to look for when deciding on a calibration lab

• Maintains the highest level of industry quality standards and requirements, traceable to the National Institute of Standard and Measurement.

• Accredited by the American Association for Laboratory Accreditation. A2LA is a non profit 3rd party that accredits calibration labs and preforms thorough assessment of all factors of testing and calibration to the ISO 17025 standard. They also preform regular comprehensive audits to ensure these standards are maintained.

• All lab technicians have continued education and testing to ensure all recent methods of calibration are being followed.

•  The company has the software to maintain a calibration production schedule for you with your specific standard requirements and will notify you when your calibrations are due.

• To provide online view of all your calibration certificates provided by the company.

What is A2LA Calibration?

 

 

What is A2LA ISO/IEC 17025 Accredited Calibration?    

 

 A2LA:

A2LA stands for the American Association for Laboratory Accreditation. It is a nonprofit 3^rd party institution that accredits calibration labs and preforms thorough assessment of all factors of testing and calibration to the ISO 17025 standard.  A2LA laboratories are audited regularly to ensure their continued compliance with requirements and to check that their standard of operation is being maintained.  Lab technicians may be required to take part in comprehensive and ongoing intense testing to ensure the most recent methods are being followed.

ISO/IEC:

Is the most important standard for calibration and testing laboratories around the world. Laboratories that are accredited to this international standard are required to include factors which determine the correctness and reliability of the tests and calibrations preformed in the laboratory by a qualified technician.  Factors that are included are environment control; equipment and measurement traceability;  testing methodology; and reporting of test and calibration results.

The benefits of  A2LA ISO/IEC 17025 certification:

• To ensure that calibration and testing are accurate and reliable.
• Laboratories comply with internationally recognized standard.
• Increase confidence in Testing and Calibration.
• Save costs on an incorrect indication. Which can cause rework, scrapped product , product recall or injury.

How do you know if your Torque Wrench needs repair?

 

5 Reasons Your Torque Wrench Might Need Repair

1) The torque wrench begins to get hard to turn.

2) There is Oxidation on ratchet kit.

3) Regular outdoor use.

4) Use in temperature room under 45 degrees.

5) Never been calibrated.

5 Ways to Prevent Damage to your Torque Wrench

1) Always keep it in a case.

2) At the end of use, set value at 20% of its max value.

3) Store torque wrench at 55 degreesa or warmer.

3) Keep away from water.

5) Regular cleaning of torque wrench.

Torque Wrench Facts

 

Torque Wrench Usage

• All mechanical torque wrenches are calibrated from 20% to 100% of full scale, therefore, they
should never be used below or above those limits
• To determine which torque wrench capacity is best suited for an application, many factors must
be considered. However, as a recommendation, use a torque wrench in the middle 50% of the
overall capacity of the tool. This will result in longer tool life, ease of use for the operator and
increased accuracy from “clicker” type torque wrenches
• Always grasp handle fi rmly in the center of the grip
• Approach fi nal torque slowly and evenly
• Stop pulling wrench immediately when target torque is reached
• Never use a torque wrench to break fasteners loose
• Should be cleaned and stored properly
• Should always be stored at it’s lowest torque setting
• Wrenches should be re-calibrated if dropped. Should never be used in excess of it’s capacity
• Torque wrenches should be “exercised” a minimum of three times at 100% of full scale before
use
• The wrench selected should be calibrated in the same torque units that are specifi ed
• Use of a “cheater bar” will result in an inaccurate reading and can possibly damage the wrench
• Torque wrenches will last longer if reasonable care is taken. Always unwind handle to the lowest
setting after each use. Do not attempt to lubricate the internal torque mechanism. Clean torque
wrench by wiping, do not immerse. The wrench should be sent to a qualifi ed calibration lab once
every year or every 5000 cycles for re-calibration
