Sine Bar (1 Products)

Sine bars are precision measurement tools used to set or check angles with high accuracy. By combining a flat bar with high-precision cylinders at each end, these tools allow machinists to create precise angles by using gauge blocks to elevate one end of the bar to a specific height, based on trigonometric principles.

Types of Sine Bars

• Standard models in sizes like 130mm, 245mm, and 350mm
• Econo sine bars in 2.5-inch and 5-inch versions
• Durable constructions for industrial use

How to Choose

Selecting the right sine bar depends on the angles you need to measure and the size of the workpiece. Precision is critical, so choose a sine bar that is manufactured to tight tolerances to ensure repeatable results. Consider the length of the sine bar, as longer bars can provide better resolution for smaller angles. Ensure you have the necessary gauge blocks to achieve the required height for your specific angle settings, and always verify the stability of the setup before beginning your measurements.
