Tool gage maintenance and operation methods

Tool Gage Maintenance and Operation:

In the measurement of machine parts, achieving the desired accuracy requires not only controlling the measurement environment but also proper use and maintenance of the measuring tools. Improper handling can lead to measurement errors, while poor maintenance may damage the tool’s precision and affect product quality. Therefore, it's essential to follow these guidelines when using and maintaining general measuring instruments:

Preparation Before Use:

(1) Always check if the measuring tool is calibrated to zero before starting any measurement.

(2) Inspect the measuring surfaces for signs of rust, wear, or scratches.

(3) Clean the workpiece by removing burrs, oil, or slag from the surface to ensure accurate readings.

(4) Wipe the measuring surfaces with a soft cloth or clean paper to avoid contamination.

(5) Keep a record of periodic inspections and make adjustments as needed.

(6) Arrange tools in an organized manner, avoiding stacking or overlapping them.

(7) Place delicate tools like optical flat mirrors on soft flannel or wiping paper to prevent damage.

Proper Usage During Measurement:

(1) Ensure proper contact with the workpiece without tilting or misalignment. Avoid touching the measuring surface directly with your hands to protect the tool.

(2) Apply the correct amount of measuring force—too much pressure can cause errors or damage the workpiece.

(3) Secure the workpiece properly to avoid inaccurate measurements due to movement or improper clamping.

(4) Never measure rotating workpieces, as this can be dangerous and lead to incorrect results.

(5) Do not force the tool into the workpiece or use it in a vise, as this may damage both the tool and the part being measured.

(6) Handle all tools carefully—never knock, throw, or drop them.

(7) Follow specific procedures when using specialized measuring tools to ensure correct operation.

Maintenance After Use:

(1) Always clean the measuring tools thoroughly after use.

(2) Apply anti-rust oil to the cleaned tools and store them in a designated cabinet.

(3) Only authorized personnel should disassemble, adjust, or modify measuring tools.

(4) Regularly check the performance of stored gauges and maintain detailed records of maintenance activities.

(5) Schedule regular inspections and keep records of comparisons and maintenance to determine whether the tool should continue to be used or be replaced.
