Precision Apparatus granite machine bases are popular among many people for their robustness and accuracy. The machine base is designed to offer a stable and precise platform for measuring equipment such as surface plates, coordinate measuring machines (CMMs), optical comparators, and other precision tools. However, before using these machines, it's important to assemble, test and calibrate them to ensure they can deliver accurate measurements. Here's a step-by-step guide on how to assemble, test and calibrate Precision Apparatus granite machine base products.
Assembling the Machine Base
1. First, unpack the machine base and inspect it for any damages that may have occurred during shipping. If there are any damages, contact Precision Apparatus to get a replacement.
2. Place the machine base on a level surface, and check with a level to ensure that it's level. If not, use shims to level the machine base.
3. Place the leveling screws into the holes provided at the corners of the machine base.
4. Place the feet of the machine base into the leveling screws and adjust to level the base.
5. Once level, tighten the screws using a torque wrench until the machine base is secure.
Testing the Machine Base
1. Place a flat surface plate on top of the machine base and check for any rocking or movement. If there is, adjust the leveling screws until the surface plate is firmly in place.
2. Test the machine base for vibration by gently tapping the surface plate with a rubber mallet. There should be no excessive vibration or movement.
3. Check the surface plate for flatness using a dial indicator. Set the dial indicator to zero on a flat section of the surface plate, then move it to different areas of the plate to check for any deviations. If there are any deviations, the machine base may need to be adjusted or calibrated.
Calibrating the Machine Base
1. Start by cleaning the surfaces where the measuring equipment will be placed using a lint-free cloth and some rubbing alcohol.
2. Place the measuring equipment on the machine base, ensuring that it's level and stable.
3. Perform a calibration check using a reference standard. A reference standard is an instrument that has been calibrated by an accredited calibration lab and is used to compare measurements taken by other instruments.
4. Mark the calibration results on the measuring instrument, making sure to note any deviations from the reference standard.
5. Make any necessary adjustments to the machine base until the measurements are within the acceptable range.
6. Perform a final check to ensure that the machine base is calibrated correctly.
In conclusion, Precision Apparatus granite machine base products are reliable and robust tools that require careful assembly, testing, and calibration to ensure that they deliver accurate measurements. By following the steps outlined in this article, you can be assured that your machine base is ready to provide precise, stable support for your measuring instruments.
