Sine, planning regulations, caliper, outside caliper

Sine: Sine ruler also known as sine sinusoidal define and measure the angle of taper in gauge, also known as sine feet. Sine: is used in conjunction with the amount of the block according to the principles of composition standard sine angle to the horizontal angle measuring the workpiece and the inner, outer cone of a precision measuring instrument by differential comparison mode. Precision 0, 1. Use standard 100 × 25 100 × 80 200 × 40 200 × 80 300 × 150 sine 1 using sine measure angle (cone) of 2, in the main body side and front, respectively, equipped for the positioning of the DUT 4 side fences and front bezel 3, which are perpendicular and parallel to the cylinder axis line two. On the surface of the sine of the face, in a body beneath the sine diameter fixed with two equal and mutually parallel cylinder 2, which under the bus tangent plane parallel with the working surface. In the main body side and front, respectively, for the DUT is equipped with a positioning side flaps 4 and front bezel 3, respectively perpendicular and parallel to the cylinder axis line two. 3, the amount of block size H is determined by sinα = H / L. Sine sine principle work, that is, between flat working surface and the side of the cylinder sine placed a set of dimensions for the Block H, so that the work surface sine flat face inclination angle α equal to the measured angle (cone ) of the nominal value, the amount of block size H is determined by sinα = H / L card board, card rules: Measuring Tool Botou City Park plant a variety of card board, card regulation, all kinds of test rods, cast iron measuring tools, granite measuring tools, magnesium aluminum flat feet, etc. straight measuring.
