Lathe fixtures are the special type of workholding devices that are used to mount the job which cannot be easily mounted on the standard work holding devices like chucks, collets, mandrels, faceplates, etc. A lathe fixture is made up of base, locating devices and clamping devices. It also consists of an arrangement for locating and … Read more
What is a Jig Bush? Jig bushes are the tools that are used to locate and guide the cutting tools like drills, boring bars, reamers, counterboring tools, etc. Jig bushes can be used on multiple faces of the component which requires machining. Jig bushings are made of which material?Jig bush is made up of either … Read more
What is Power Clamping/Power Clamps? Power Clamps are the power driven work holding clamps that are quick acting, controllable, reliable and operated without fatigue to the operator. Power clamping is generally done by using hydraulic power or pneumatic power. Based on this, the power clamping devices are of two types; Hydraulic clamps and Pneumatic clamps … Read more
What are fixture clamping devices? Fixture clamping devices are the mechanical clamps that hold the workpiece and keep it stable against all the distributing forces that come on it during a machining process. The clamping devices should be clamped in such a way that the clamping pressure should not be directed towards the cutting operation … Read more
What is a lever clamp? A lever type clamp is a clamp that has a shape of a mechanical lever. The lever clamps are used to rigidly hold the workpiece with the fixture and keep it stable against all the distributing forces during a machining process. Lever type clamps are simple in design and are … Read more
What are locating devices? Locating devices are the components that are used to quickly and easily position (or locate) the part with respect to the workpiece. With the help of locating devices, the parts can be set up quickly and hence the machining can be done easily and quickly. On the basis of nature of … Read more
What is Thread Rolling? Thread rolling is a cold working technique of making external threads on the cylindrical workpiece. In Thread Rolling, the threads are made by pressing the thread rolling dies against the workpiece. By using thread rolling, the operation can be performed very fast and hence a large number of components can be … Read more
What is Thread Grinding? Thread grinding is a process of either cutting or finishing the threads on a workpiece by using a specially dresses grinding wheels. The principle of thread grinding is similar to thread milling, but here the grinding wheel is used instead of milling cutter. The grinding wheel consists of abrasive particles on … Read more
What is thread milling? Thread milling is a method of producing threads on a workpiece by using a thread milling cutter. Thread milling has following advantages over threading taps and threading dies. It is a faster operation Risk of tool breakage is less Left and right hand threads can be machined with a dame tool … Read more
What is a Threading die? Threading die (also known as thread cutting die) is a tool used to cut external threads on cylindrical or tapered surfaces. They are made of HSS or hardened tool steel and have sharp internal cutting edges. The thread cutting dies are rotated around the workpiece by using a handle or … Read more
