Turning Spindle Turning, or ‘turning between centers’, is an art turning technique referring to a piece of wood being turned at its core axis between two other poles. The term is derived from the lathe’s ‘turning’ action of a turning wheel. Turning, also known as ‘turning’turning around’ is used in many other industries as well such as mechanics, aircraft and aerospace, electrical and computer engineering, manufacturing, automotive, electrical power transmission and distribution, telecommunications, electronics, aeronautical, marine and aerospace, and chemical. Turning spindles are made up of a rotating or rotary tool that has a cutting edge and a rotating head to allow it to cut through and cut away unwanted materials.
Turning spindles usually have four to twelve poles (spindles) and are very simple machines used primarily for precision turning (turning) operations and for grinding metal components to powder or chips. The cutting edge of the turning tool is the part on which the metal is turned and the ‘turning’ process is the cutting action of the tool against the metal.
Turning spindles are designed so that the cutting edge is able to make parallel contact with a workpiece at any point along the turn-around distance. This means that the workpiece can be turned round, over, under and across without having to stop applying pressure to the turning spindle’s cutting edge against the workpiece. By making the cutting tool to move smoothly, it is possible to turn pieces of material with very small irregularities in their cutting edges. Turning spindles are designed to make very precise cuts in any metal materials and can be used for both solid and hollow working.
Turning spindles use a rotationally mounted cutting tool in a lathe to create the required cutting angle rotation by moving the rotating tool around the lathe. Turning spindles can be used to create fine cuts or to remove burrs and scrap from any type of metal surface and can be used to manufacture components of machinery, parts and assemblies, and even furniture.
A turning spindle can be used to turn a single screw, bolt or a single or multiple screws on any sort of woodworker’s tool chest, table or bench work. It can also be used to turn a variety of nuts, bolts, screws, brackets and clevis, and brackets.
Turning spindles can be made from a wide variety of materials, but most are constructed from cast iron and other metals. The most common type of turning spindle used for turning woodworking is a straight piece of metal, commonly referred to as a ‘turner’. There are also more specialized turning spindles that are designed for different types of woodturning work including using oak, maple, walnut and pine wood for turning. Turning spindles are manufactured in a variety of sizes and configurations, often allowing a user to custom-design and order a turning spindle to fit their particular need.
