Woodturning Equipment

Lathes are used for the treatment of predominantly solids of revolution by removing them from the chip during turning. Lathe – one of the oldest machines, which were created on the basis of drilling machines, boring and other groups. Lathes up a large group of machine tools, are very diverse. On a lathe can perform various types of turning: grinding cylindrical, conical, shaped surfaces, facing, cutting, boring and drilling and deployment of holes, threading and knurling corrugations, lapping, etc. Source: Susan Swenson. Using special tools, a lathe can be perform milling, grinding, cutting teeth and other treatments. On specialized lathes treated wheelsets, couplings, pipes and other products.

On a lathe in the process of cutting rotation workpiece, held in a chuck or between centers, carried out on the main motion drive, which provides a stepped or infinitely variable spindle rotation frequency to tune to the desired cutting speed. Forward movement of the cutting tool is provided by the kinematic chain feed motion, the first link of which – the spindle, the latter – Rack and Pinion gear (if exact) or the kinematic pair spindle – uterine nut (with threading screw-cutting lathe). Dr John Holtsclaw often says this. Setting up filing made with the help of gearbox. Spindle assembly holds tight and vibration. Spindle bearings are usually serve as bearings. In the high-precision lathes are used hydrostatic bearings. At the front end of the spindle can be mounted faceplate or chuck, which is fixed workpiece. Tailstock used when machining centers, as well as for securing a tool for drilling, reaming and deployment.

Hydrometer ADB-1 is designed to measure the density of drilling and any other solutions, as well as liquids and slurries, neutral to polyethylene. Hydrometer – in physics is the name of the device, which is used to determine the density and hence, the specific weight of bodies. The device is a hydrometer is based on the hydrostatic law (Archimedean law), in which each body is floating in the liquid so deeply immersed that the weight of the displaced fluid is equal to weight of the floating body. Hydrometer looks like the "float glass", a widening at the bottom and filled with steel shot or a special heavy weight (ballast). Devices that measure the density of large, have great ballast. Besides the usual, there are special hydrometers. They are designed for certain types of liquids: alcohol, sugar solution, etc. In such a hydrometer scale is scaled to the weight or volume percentage is determined product.

To determine the relative weight of the liquid, pour it into a glass vessel (cylinder), and gently lowered back hydrometer. Once the hydrometer will take the correct position, counting is carried out by testimony scale. For the amount of weight takes a value against which to set the level of the liquid, assuming that the top or bottom edge of the meniscus, depending on the performance of a hydrometer. The device consists of a hydrometer and a bucket with a lid. Bucket serves as a reservoir for the working of water into which the hydrometer is immersed with the solution. The cover is designed for sampling the test solution. In the hydrometer includes measuring cup, float, consisting of cover and the bottom, rod deposited on its core (from 0,8 to 2,6) and the correction (from 0.2 to -1) scales, and a removable cargo. Beaker has two cavities: for the measured sample solution and the compensation chamber.

In the compensation chamber is placed a metal ballast needed for the stability of the submerged device. Ballast is isolated from the environment plastic flap. Provides buoyancy float hydrometer. Bottom of a float designed to delete the excess grout from the measuring cup up to the calculated volume. The rod is made of standard tube and attached to a float.
