A mandrel is an auxiliary device for the formation of cavities and is utilized in metal forming for indentation or forcing-through procedures. There is a differentiation between hollows and solid mandrels. For seamless tube production, mandrels are utilized for bar extrusion as well as for mandrel drawing as auxiliary devices, whereat the mandrel always determines the inner diameter of the deformed tube.
Usually a fixed tool on a slide forming machine that metal formed against by the action of a glide mounted form tool.
A short shaft of uniform or varying diameter upon which various pieces pieces of metalwork can be mounted for turning in a lathe. A metallic core used in driving Raymond or Simplex piles.
A tapered steel rod around which composite materials are wrapped when making a shaft.
A round shaft used to mount a stone, cutter, saw, etc.
usually a steel, aluminum or other alloy shape (extruded or machined) that will form the internal shape of a dip molded part. Multiple mandrels are normally mounted to a bar. The bar is then placed into a master rack or mounted directly on the arm of the machine.
spindle or bar of a lathe (for instance) that supports the material being turned. - World Book Dictionary.
the shaft or spindle on which a cut-off wheel, drum sander or polishing wheel is mounted.
A steel rod slightly tapered, used by jewelers as an anvil for forming or sizing rings.
A blunt-ended tool or rod used to retain or enlarge the cavity in a hollow metal product during forging.
any of various rotating shafts that serve as axes for larger rotating parts
a little tool that lets you attach your wheel to the end of an electric drill
a straight steel shaft that allows you to mount and turn the pen blanks on your lathe
Shaft of steel or wood used for mounting and turning of grips, reel seat inserts, etc.
Tapered steel shaft. Used as the core around which a composite pattern or flag is wrapped during the process of making a rod blank. It is removed after the blank has been heated and cured.
A bar used to retain the cavity or enlarge the bore during hollow forging.
A shaft upon which cylinders or other items are located for support during a print run. Also applies to unwind and rewind shafts onto which rolls of material or finished labels may be wound.
A handheld tool used to securely hold a tube/staple during the reed-tying process.
a tapered form around which metal is shaped
Bar of metal used to size rings.
The threaded member of the installation tool that engages the threads of the insert and applies the installation load. Spin-spin tools typically use a standard socket head cap screw as a mandrel. Most spin-pull tools use a more complex mandrel, but some newer tools use a standard socket head cap screw. To install an insert with external threads, the mandrel has internal threads.
This word is mostly used for holding device which grips the workpiece internally - such as the special mandrels for pen making. In the old days the mandrel was the lathe spindle - the rotating shaft in the headstock.
A cylindrical shaft around which wire is wound to form coils, usually for the purpose of making rings.
A metal bar that serves as a core around which material (as metal) may be cast, molded, forged, bent, or otherwise shaped.
An accurately machined shaft on which work is mounted for balancing.
A round metal bar or rod 25 mm (1 in.) in diameter and approximately 460 mm (18 in.) long. Used in ASTM testing for flexibility of materials.
a cylindrical bar, spindle, or shaft around which other parts are arranged or attached or that fits inside a cylinder or tube.
A faceplate fitted with "dogs" or clips to hold the work during turning, fitted to the lathe. or as a seperate self contained tool. In engineering, a mandrel is a bar set between centers to mount tools or work.
1. A tapered axle inserted into a hole in a piece of work to support it during machining. 2. A metal bar used as a core around which material may be cast, molded, forged, bent, or otherwise formed. 3. The shaft and bearings on which a tool is mounted, as in a drill or circular saw.
A shaft upon which cylinders, or other devices, are mounted or affixed.
1. Metal spindle used in a lathe center to hold the work that is being turned. 2. Tool used to form. 3. Threaded steel shank used in a rotary driver.
A mandrel (pronounced , and also spelled mandril; in American English also called an arbor) is either an object used to shape machined work; a tool component that grips or clamps materials to be machined; or a tool component that can be used to grip other moving tool components.
