10 inch sine bar constants


Both sine and rolls hardened and ground for extreme accuracy.

Attorney, Agent or Firm: LOW & LOW (2316 S. EADS STREET, ARLINGTON, VA, 22202, US) Claims: 1. 1.21. 52-455-010 (Gage block shown not included.) Sine Bars & Sine Plates No. Qty: Compare. Both sine and rolls hardened and ground for extreme accuracy. No. Sine bar is also available in inches. Primary Examiner: HOLTJE, NELSON C . Features: • Top surface is accurate to .00003" per inch of length. To set an angle on any sine device, whether it is a sine bar, sine plate, compound sine plate, or other sine tool, you must first determine the center distance of the device (C) and the angle you wish to set (A).

The height is obtained from the dimension between the bottom of one roller and the table's surface. The hypotenuse is a constant dimension—(100 mm or 10 inches in the examples shown). Fowler Sine Bar equipment used with gage blocks is highly recommended for securing a high degree of accuracy in measuring angles for grinder and milling machine set ups. Fowler Sine Bar equipment used with gage blocks is highly recommended for securing a high degree of accuracy in measuring angles for grinder and milling machine set ups. Parallelism: .0004". Example: You need to set a 5.0” sine bar or sine plate to 37° SIN (37) = .601815023

The ornamental design for a constant sine bar, substantially as shown anddescribed. To calculate the gage blocks height needed to set-up a sine bar to a specific angle all you have to do is take the SIN of the angle and multiply it by the sine bar length.The length of the sine bar is the distance between the centers of the sine bar gage pins. nearest minute) for a 5 inch sine bar. Fowler 12 Piece Angle Block Set 52-666-777-0.
If one roller is raised by a known distance, usually using gauge blocks, then the top edge of the bar will be tilted by the same amount forming an angle that may be calculated by the application of the sine rule. The angle is calculated by using the sine rule. Different available types of sine bar are shown in fig. Fowler Set of 12 Angle Plates 53-666-000-0. The hypotenuse is a constant dimension—(100 mm or 10 inches in the examples shown). • Flange on end of Bars and Plates for resting work. Part Number … American Machinist-6/6/46-p. 143-Sine Bars. Description: FIG. 52-455-015 (Gage block shown not included.) In a right angle triangle ABC shown in Fig. Sine Bars and Angle Blocks. Qty: Compare. 52-455-020 No. Tables are not normally available Tables are not normally available for 10 inch bars because it is just as easy to use the sine of the angle and Principle of Working of Sine Bar: The principle of operation of the sine bar is based upon the application of trigonometry.

The sine tables provided in this booklet are the basic sizes needed to set an angle on most sine products.
Next, you must look up the 'setting constant' in the appropriate table.
