THE TRUNCATED AND COUNTERBORED BALL IS THE SECOND MOST WIDELY USED KINEMATIC COMPONENT. IT IS USED WHERE THE COMPONENT MUST BE HELD IN PLACE FROM THE FRONT SIDE.
THREE OF THESE BALLS PROVIDE A VERY HIGH-QUALITY SUBSTITUTE FOR A CONICAL CUP OR A TRIHEDRAL CLAMP.
THESE BALLS ARE A GOOD CHOICE FOR THE THREE SPHERICAL CONTACT POINTS IN THE KINEMATIC SYSTEM WHEN THE BALL CAN ONLY BE HELD IN PLACE FROM THE FRONT SIDE.
THIS COMPONENT HAS A MUCH LOWER PROFILE THAN A COMPLETE BALL.
THIS COMPONENT HAS A .005" DEEP RECESS ON THE FLAT SURFACE THAT IS MADE VERY ROUGH BY ELECTRICAL DISCHARGE MACHINING. WHEN MAXIMUM RELIABILITY IS REQUIRED, GLUE MAY BE APPLIED TO THIS ROUGH SURFACE TO FORM A PERMANENT BOND BETWEEN THIS COMPONENT, THE MACHINE SCREW, AND THE MOUNTING SURFACE. THIS COMPONENT IS MACHINED FOR USE WITH A STANDARD SOCKET HEAD CAP SCREW.
