The screw thread
External threads can be cast. Due to the need of casting or mold structure, the machining allowance of 0.2~0.3mm shall be kept when the two-half split ring is used. The minimum pitch can be cast is 0.75mm, the outer diameter of the minimum thread is 6mm, and the maximum thread length is 8 times of the pitch.
Although internal threads can be cast, they can be made more complicated and cost more by using mechanical devices to rotate the core of the die. So generally cast out the bottom hole first, and then machining into internal threads.
Surface roughness measurement method
1. The comparison method
Used for field measurement in workshop, often used for measurement of medium or rough surface. The method is to compare the measured surface with the roughness sample marked with a certain value to determine the roughness value of the measured surface.
2. Touch the stitch
Surface roughness using tip curvature radius of about 2 micron diamond stylus slide along the surface to be tested is slow, diamond stylus and displacement by the electrical length sensor is converted to electrical signals, amplifying, filtering, calculated by the display instrument indicates that the surface roughness value, also can use recorder to record measured section contour curve. Generally, the measuring tool that can only display the surface roughness value is called the surface roughness measuring instrument, and the one that can record the surface contour curve is called the surface roughness profiler. These two measurement tools have electronic computing circuits or computers, which can automatically calculate the contour arithmetic mean deviation Ra, micro roughness ten-point height Rz, contour maximum height Ry and a variety of other evaluation parameters. The measurement efficiency is high, which is suitable for measuring the surface roughness Ra is 0.025 ~ 6.3 micron.
