Drilling of steel balls is often encountered in the machining process, often in small batch production. It is not economical to design and manufacture special drills. To this end, I designed a high precision and adaptable drill according to the principle of taper surface positioning of the spherical workpiece (as shown). The die drill sleeve 3 and the die outer cover body 2 can be matched by H7/P6. After the die outer cover body 2 and the die support body 1 are pressed against the workpiece, the fastening screw 4 is tightened to drill the hole. The outer diameter of the drill support 1 is matched with the inner hole of the outer casing 2 by H7/h6.
Touch screen Heat deflection temperature and Vicat Softening Point Tester
Heat deflection temperature (HDT) and Vicat softening temperature testing is critical to determining the quality and performance of polymers.
HDT and Vicat temperatures are critical properties for measuring the quality and performance of high-performance polymers:
- The HDT test for plastics measures the temperature where deformation occurs under a specified load;
- The Vicat apparatus test measures the softening temperature of a material.
