Everything You Want To Know About Sine Bar

A sine bar is a precision measuring tool used in metrology (the science of measurement). It is primarily used to measure angles with a high degree of accuracy. The sine bar consists of a hardened, flat bar with two accurately ground cylindrical surfaces at its ends. These cylindrical surfaces, known as rollers, serve as reference points for measurement. The sine bar works based on the trigonometric relationship between the length of the bar and the angle formed between it and the surface it rests on. 

What Are The Types Of Sine Bars?

Depending upon the usage, there are types of sine bars. Let us have a look:

There are primarily two types of sine bars commonly used:

  1. Plain Sine Bar: A plain sine bar tool consists of a single bar with two cylindrical rollers at its ends. The bar is typically made of hardened steel, and the rollers are precision-ground and finished. The length between the rollers is a known value. It is the simplest and most commonly used type of sine bar.

  1. Compound Sine Bar: A compound sine bar tool, also known as a universal sine bar, consists of two sine bars of different lengths. The two bars are joined together at one end, forming an "L" shape. Each bar has its own set of rollers. The compound sine bar allows for measuring a wider range of angles by combining the angles obtained from each sine bar.

What Are The Applications Of Sine Bars?

Sine bars have several applications across various industries. Here are some common applications:

  1. Angle Measurement: The primary sine bar use is for accurately measuring angles. They are employed in machining and toolmaking operations where precise angles need to be achieved, such as setting up milling cutters, grinding wheels, or drilling operations at specific angles.

  1. Inspection and Quality Control: Sine bars are utilized in quality control processes to verify the accuracy of machined components. They are used to measure the angles of manufactured parts and ensure they meet the required specifications and tolerances.

  1. Setting Angles on Machines: Sine bars are employed to set angles on various machines, including milling machines, lathes, and surface grinders. By using a sine bar along with height gauges or other measuring tools, operators can accurately set the desired angle for machining operations.

  1. Calibration of Measuring Instruments: Sine bars are utilized in the calibration of other measuring instruments. They can be employed to calibrate angle measurement devices, such as angle plates, bevel protractors, or digital angle finders, ensuring their accuracy.

  1. Precision Engineering: Sine bars find extensive use in precision engineering, where high accuracy is crucial. They are employed in the production of complex components, jigs, fixtures, and tooling, where achieving precise angles is vital for the functionality and performance of the final product.

  1. Research and Development: Sine bars are used in research and development settings where precise measurements and angles are required. They are commonly employed in scientific laboratories, engineering research facilities, and educational institutions for experimental purposes and prototyping.

What Factors Should You Consider Before Buying Sine Bars?

When considering buying sine bars, there are several important points to keep in mind. Here are some factors to consider:

  1. Accuracy: The accuracy of the sine bar tool is crucial. Ensure that the sine bar you are considering has a high level of precision. Look for bars that are made from high-quality materials and have undergone proper calibration and testing procedures.

  1. Length and Range: Determine the range of angles you need to measure. Choose a sine bar that provides the required range and has suitable lengths between the rollers. If you anticipate measuring a wide range of angles, a compound sine bar may be a more versatile option.

  1. Material and Construction: Sine bars are typically made from hardened steel or other durable materials. Consider the material used and ensure it provides the necessary strength, rigidity, and stability for your intended applications. The construction should be solid, with accurately ground rollers and precise alignment.

  1. Certification and Traceability: Check if the sine bar tool comes with a calibration certificate or if it has been certified by a reputable metrology laboratory. This provides assurance of the accuracy and traceability of the measurements.

  1. Ease of Use: Consider the user-friendliness of the sine bar. Look for features such as clear markings, easy adjustment mechanisms, and ergonomic design that facilitate accurate and convenient measurements.

  1. Compatibility with Accessories: If you plan to use additional accessories or attachments with the sine bar, ensure compatibility with the specific model you are considering. This includes accessories like height gauges, angle plates, and blocks.

  1. Brand Reputation and Reviews: Research the reputation of the manufacturer or brand. Look for customer reviews and feedback to gauge the reliability and performance of the sine bar. 

  1. Cost and Budget: Consider your budget and the value offered by the sine bar. While it's important to prioritize quality and accuracy, ensure that the chosen sine bar fits within your budget and provides a good balance between sine bar price and performance.

Considering these factors will aid you in making an informed decision and selecting a sine bar that meets your specific requirements, ensuring accurate and reliable angle measurements in your applications. Buy sine bars, dividers and other testing and measuring instruments from Industrybuying.

Frequently Asked Questions Related To Sine Bar

1Can a sine bar be used to measure angles other than right angles?

Yes, a sine bar can be used to measure angles other than right angles. The length of the bar between the rollers can be used to calculate the angle using the sine function.

2.How does temperature affect the accuracy of a sine bar?

Temperature can affect the accuracy of a sine bar by causing thermal expansion or contraction of the material. This can result in dimensional changes, potentially leading to deviations in the measured angles.

3.What are the common accessories used in conjunction with sine bars for angle measurement?

Common accessories used with sine bars for angle measurement include angle gauges, height gauges, V-blocks, and dial indicators.
