Measuring Tools Are Measuring Tools Means Used By Machining Workshops To Ensure The Quality Of Machining Of Mechanical Parts . The Accuracy Of Measuring Tools Determines The Precision Control Of Machined Products. If The Measuring Tool Is Accurate Enough, The Measurement Result Will Be Inaccurate, It Will Be Impossible To Truly Confirm Whether The Product Is Qualified . Commonly Used Measuring Tools: Ordinary Calipers, Digital Calipers, Depth Calipers, Calipers With Dial Indicators, Micrometers (Inside Outside Diameters), Depth Micrometers, Tooth Thickness Normal Micrometers, Height Gauges, Ordinary Depth Gauges, Feeler Gauges, Internal External Thread Gauges, R Gauges, Dial Indicators, Micrometers, Gauge Blocks, Roughness Control Blocks, Height Gauges, Projectors, Three-Dimensional Coordinate Measuring Machines, Two-Dimensional Measuring Machines, Etc.

Before Each Measurement, It Is Necessary To Measuring Tools According To The Special Characteristics Of The Measured Parts. For Example, Calipers, Height Gauges, Micrometers, Depth Gauges Can Be Used For Length, Width, Height, Depth, Outer Diameter, Step Difference; Micrometers Calipers Can Be Used For Shaft Diameters; Plug Gauges, Block Gauges, Feeler Gauges Can Be Used For Holes Slots; Square Rulers Are Used To Measure The Straightness Of Parts; R Gauges Are Used To Measure R Values; Three-Dimensional Two-Dimensional Dimensions Can Be Used To Measure Small Tolerances, High Precision Requirements, When Calculation Of Form Position Tolerances Is Required; Hardness Testers Are Used To Measure The Hardness Of Steel. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience .

1. Application Of Calipers

Calipers Can Measure The Inner Diameter, Outer Diameter, Length, Width, Thickness, Step Difference, Height Depth Of Mechanical Parts Processing Objects; Calipers Are The Most Commonly Used Convenient Measuring Tools, Are The Most Frequently Used Measuring Tools At The Processing Site.

Digital Caliper: Resolution 0.01mm, Used For Dimensional Measurement With Small Tolerance (High Precision).

Table Card: Resolution 0.02mm, Used For Conventional Size Measurement.

Vernier Caliper: Resolution 0.02mm, Used For Rough Machining Measurement.

2. Application Of Micrometer

Before Using The Micrometer, You Need To Remove Dust Dirt With A Clean White Paper (Use The Micrometer To Measure The Contact Surface Screw Surface, Hold The White Paper Then Pull It Out Naturally, Repeat 2-3 Times), Then Twist The Knob, When The Measuring Contact Surface The Screw Surface Are About To Contact, Use Fine Adjustment Instead. When The Two Surfaces Are In Full Contact, Adjust To Zero You Can Start Measuring.

When Using A Micrometer To Measure Precision Hardware , Adjust The Knob. When It Is About To Touch The Machined Part, Use The Fine-Adjustment Knob To Turn It In. When You Hear Three Clicks, Stop, Read The Data The Display Scale. When Measuring Plastic Products, Just Make Sure The Measuring Contact Surface The Screw Lightly Touch The Product.

When Using A Micrometer To Measure The Diameter Of A Shaft, Measure In At Least Two Directions Take The Maximum Value In Segments. During The Measurement, The Two Contact Surfaces Of The Micrometer Should Be Kept Clean At All Times To Reduce Measurement Errors.

3. Application Of Height Gauge

Height Gauges Are Mainly Used To Measure The Height, Depth, Flatness, Verticality, Concentricity, Coaxiality, Surface Vibration, Tooth Vibration, Depth Other Aspects Of Mechanical Parts. When Measuring With A Height Gauge, You Must First Check Whether The Probe The Connection Parts Are Loose.

4. Application Of Feeler Gauge

Feeler Gauges Are Suitable For Measuring The Flatness, Curvature Straightness Of Mechanical Parts.

Flatness Measurement:

Place The Precision CNC Parts On The Platform Use A Feeler Gauge To Measure The Gap Between The Parts The Platform (Note: The Feeler Gauge The Platform Should Be Tightly Pressed Without Gap During Measurement)

Straightness Measurement:

Place The Precision Part On The Platform Rotate It One Circle, Then Use A Feeler Gauge To Measure The Gap Between The Part The Platform.

Curvature Measurement:

Place The Machined Part On The Platform The Corresponding Feeler Gauge To Measure The Gap Between The Two Sides The Middle Of The Part The Platform.

Verticality Measurement:

Place One Side Of The Zero Right Angle To Be Measured On The Platform, Place The Square Ruler Close To It On The Other Side, Use A Feeler Gauge To Measure The Maximum Gap Between The Part The Square Ruler.

5. Application Of Plug Gauge (Needle)

Suitable For Measuring The Inner Diameter Of Holes, Slot Widths, Gaps.

When The Hole Diameter Of The Part Is Large There Is No Suitable Pin Gauge, Two Plug Gauges Can Be Overlapped Measured In A 360-Degree Direction. The Plug Gauge Is Fixed On A Magnetic V-Shaped Block To Prevent Loosening Facilitate Measurement.

6. Precision Measuring Instrument: Secondary Element

The 2D Element Is A High-Performance, High-Precision Non-Contact Measuring Instrument. The Sensing Element Of The Measuring Instrument Does Directly Contact The Surface Of The Measured Part, So There Is No Mechanical Measuring Force; The 2D Element Transmits The Captured Image To The Computer's Data Acquisition Card Through A Data Cable By Projection, Then The Software Forms An Image On The Computer Monitor; It Can Measure Various Geometric Elements (Points, Lines, Circles, Arcs, Ellipses, Rectangles), Distances, Angles, Intersections, Form Position Tolerances (Roundness, Straightness, Parallelism, Verticality, Inclination, Position, Concentricity, Symmetry) On The Parts, Can Also Output CAD For 2D Depiction Of The Outer Contour. Only Can The Contour Of The Workpiece Be Observed, But The Surface Shape Of Opaque Workpieces Can Also Be Measured.

Electrode Processing Surface Observation: The Two-Dimensional Lens Has A Magnification Function To Inspect The Roughness Of The Electrode After Processing (Magnify The Image 100 Times).

Gate Detection: During Mold Processing, There Are Often Some Gates Hidden In The Groove, Various Detection Instruments Cannot Measure Them. At This Time, Rubber Clay Can Be Pasted On The Rubber Mouth, The Shape Of The Rubber Mouth Will Be Printed On The Rubber Clay. Then Use The Second Element To Measure The Size Of The Rubber Clay Print To Get The Gate Size.

Note: Because There Is No Mechanical Force When Measuring With Two-Dimensional Element, It Is Best To Use Two-Dimensional Element To Measure Thinner Softer Products.

7. Precision Measuring Instruments: Three-Dimensional

The Characteristics Of Three-Dimensional Measurement Are High Precision (Up To Μm Level); Versatility (Can Replace A Variety Of Length Measuring Instruments); Can Be Used To Measure Geometric Elements (In Addition To The Elements That Can Be Measured By Two-Dimensional Measurement, It Can Also Measure Cylinders Cones), Form Position Tolerances (In Addition To The Form Position Tolerances That Can Be Measured By Two-Dimensional Measurement, It Also Includes Cylindricity, Flatness, Line Profile, Surface Profile, Coaxiality), Complex Surfaces. As Long As The Three-Dimensional Probe Can Reach A Place, Its Geometric Dimensions, Relative Positions, Surface Contours Can Be Measured; Data Processing Can Be Completed With The Help Of A Computer; With Its High Precision, High Flexibility Excellent Digital Capabilities, It Has Become An Important Means Effective Tool For Modern Mold Processing Manufacturing Quality Assurance.

Some Molds Are Being Modified Do Have 3D Drawings. The Coordinate Values Of Each Element The Contours Of Irregular Surfaces Can Be Measured. Then, The Drawing Software Can Be Used To Export Make 3D Graphics Based On The Measured Elements, So That Fast Accurate Processing Modification Can Be Performed (After The Coordinates Are Set, The Coordinate Values Of Any Point Can Be Measured).

Import Compare 3D Digital Models: For Finished Parts, In Order To Confirm The Consistency With The Design Find Abnormal Fit During The Assembly Of The Fit Mold, When Some Surface Contours Are Neither Arcs Nor Parabolas, But Some Irregular Surfaces, It Is Impossible To Measure The Geometric Elements. You Can Import The 3D Model Compare The Parts To Understand The Processing Errors. Because The Measured Value Is The Point-To-Point Deviation Value, It Is Easy To Make Quick Effective Corrections Improvements (The Data Shown In The Figure Below Is The Deviation Between The Measured Value The Theoretical Value).
