The present invention makes a rotary movement smooth, the rotary movement allowing direct detection of the movement of an output member of a rotary clamp. In a clamp, an output member is accommodated in a cylinder hole. A first valve chamber, to which compressed air is supplied, is provided between a lower wall of a housing and the output member. A second valve chamber is a hollowed out portion of the output member so as to be provided open toward the first valve chamber. A valve rod is inserted into the second valve chamber from the lower wall. A valve rod passage that allows the second valve chamber to communicate with outside air is provided in the valve rod, and a seal section is provided in a peripheral gap where the valve rod and the second valve chamber move relatively to one another. The gap is formed so that, as the valve rod and the second valve chamber are in relative movement, there is a region which is sealed by the seal section against movement of the compressed air through the gap between the valve rod and the second seal chamber and the there is a region which is open from the seal.

METHOD OF MONITORING A TOOL CLAMPING DEVICE

A method of monitoring a tool clamping device mounted on a machine spindle, the clamping force of which tool clamping device is generated by a spring assembly which exerts a force in the direction of the clamping position on an actuating element actuating the clamping or the release of a tool or tool holder. In the method, the spring force and the displacement of the actuating element are continuously measured during the release and/or clamping of a tool or tool holder and recorded as functions of the time. These recorded functions are used to identify at least one parameter characteristic for the status of the tool clamping device. Based on the spring force and the displacement over time, a spring characteristic curve is plotted in the form of the spring force as a function of displacement, the analysis of which spring characteristic curve provides information about a number of characteristic parameters.

Additive lathe that prints in cylindrical coordinates
10906243 · 2021-02-02 ·

An additive lathe integrates the advantages of additive manufacturing (also called 3d printing) with the cylindrical motion of a lathe to reduce material waste, print times, and increase creative potential. A post-processing system allows for an improved surface finishing on parts. The additive lathe no longer prints in cartesian (X, Y, Z) coordinates as other 3D printers and instead prints using cylindrical (R, Theta, Z) coordinates. The traditional bed or build plate is replaced with a horizontal cylindrical starter bar, on which 3D printed material is deposited along and around the bar. Essentially, the additive lathe works like a conventional lathe, but in reverse. Instead of taking a cylinder and slowly removing material as the part spins, the additive lathe adds material along and around the bar iteratively building up the part. The finishing mechanism allows for the creation of a smooth outer finish on printed parts while still in the printer.
