Angle Gauge Block Set  7Piece
SERIES 571
SERIES 571
An angle gauge block set, also known as angle gauge blocks or sine gauge blocks, is a precision tool used to measure and set specific angles with a high degree of accuracy. These blocks are typically used in machining, inspection, and metrology applications where exact angular measurements are required, such as setting up equipment, verifying the accuracy of angled features, or calibrating other measurement instruments.
 For angle comparison
 One angle can be as used in triangle blocks four angles can be as used in rectangle blocks
Applications of Angle Gauge Block Sets:
 Precision Machining: For setting up equipment to cut or machine parts at exact angles.
 Tool and Die Making: Essential for setting angles in dies, molds, and cutting tools.
 Quality Control and Inspection: Used in metrology labs or quality control settings to verify that angular dimensions meet specified tolerances.
 Calibration of Measuring Tools: Angle gauge blocks are used to calibrate tools like protractors, angle finders, and other angular measurement instruments.
How Angle Gauge Blocks are Used:
 Wringing Blocks Together:
 To achieve a specific angle, angle gauge blocks can be stacked (wrung) together by combining different blocks. For example, combining a 30° block with a 10° block will give a total angle of 40°.
 Use with Sine Bars:
 A common application is using angle gauge blocks with sine bars or sine plates. By stacking the blocks under the sine bar, the sine of the angle can be calculated, and the precise angle can be set or measured.
 Direct Angle Measurement:
 The blocks can also be used directly to check or set the angles of components, machine setups, or fixtures.
Example of Using Angle Gauge Blocks with a Sine Bar:
 Place a sine bar on a flat surface.
 Stack the angle gauge blocks under one end of the sine bar.
 The height of the stacked blocks and the length of the sine bar allow the user to calculate the angle by taking the sine of the angle formed.
 This allows for highly precise angular setups or measurements in machining or inspection processes.
Key Features of an Angle Gauge Block Set:

Precision Machined Blocks:
 Each block in the set is precision ground and polished to form a specific angle with a high level of accuracy. The angles are usually defined in degrees, minutes, and seconds (or fractions of a degree).
 Common angles include 15°10', 30°20' , 45°30', 50°, 60°40' , 75°50' , 90°, and so on, but the set also contains fractional angles like 1 minute (1') and seconds for finer adjustments.

Material:
 The blocks are typically made from hardened steel or chromium carbide for durability and longlasting precision.
 Some sets are made from ceramic materials, offering better wear resistance, especially in environments where frequent use occurs.

Angle Combination:
 The blocks in an angle gauge set can be combined to create composite angles. By stacking and wringing multiple blocks together, the user can create nonstandard angles by summing the angles of individual blocks.
 This allows for extreme flexibility in measuring or setting a wide range of angles that are not directly provided by the blocks alone.

Wringing Ability:
 Similar to gauge blocks used for linear measurement, angle gauge blocks can be 'wrung' together. This wringing occurs due to the perfectly flat and polished surfaces of the blocks, creating a nearperfect fit when placed together, with minimal air gap between them.
 This ensures that the combined angle created by multiple blocks is extremely accurate.

High Accuracy and Tolerances:
 Angle gauge blocks are manufactured to tight tolerances, typically within a few seconds of a degree (e.g., ±3 seconds). This makes them suitable for the most demanding precision applications.
 Calibration of the blocks ensures traceability to recognized standards, such as ISO.

Range of Angles:
 Angle gauge block sets are available in various configurations, typically
including blocks with angles such as:
 Angle 15°10', 30°20' , 45°30', 50°, 60°40' , 75°50' , 90°
 Smaller fractional angles, such as 1 minute (1'), 5 minutes (5'), 10 minutes (10'), and seconds (arc seconds) for more precise measurements.
 Angle gauge block sets are available in various configurations, typically
including blocks with angles such as:

Applications:
 Setting Angular Tools: Angle gauge blocks are used to set up milling machines, grinders, lathes, and other machine tools for specific angular cuts or machining operations.
 Inspection and Calibration: They are often used to inspect and calibrate the angles of machined parts, fixtures, tools, and gauges.
 Angular Measurement: Used with instruments like sine bars or sine plates to measure or set very precise angles on components or tooling.
 Angle Comparisons: The blocks can be used to verify the angle of angled features on parts or to compare the measured angle against a standard reference.

Calibration and Traceability:
 Angle gauge blocks are usually provided with a calibration certificate, ensuring their accuracy and traceability to national or international standards.
 Regular recalibration of angle gauge blocks is essential to ensure they maintain their precision over time, especially if used frequently.
