What is spinning metal process?
Metal spinning is a method of forming rotationally symmetrical sheet metal parts. In spinning, the sheet metal discs are formed into rotationally symmetrical hollow shapes. The blank is clamped between the shaped spinning mandrel and the tailstock of the spinning machine and rotated by the main drive.
Why is metal spinning done?
Since it compresses metal pieces, metal spinning may increase the strength and performance over the finished product. As the CNC lathe exposes the metal piece to rotational force, the metal piece compresses and deforms, thus increasing its tensile strength.

Which is the disadvantage of spinning process?
Manual spinning requires that operators have a high level of skill as well as a fair amount of strength, as the process is physically demanding. Also, compared to similar metal-shaping techniques -- such as press forming -- manual metal spinning takes more time before a usable piece is finished.
What is shear spinning?
Shear forming, also referred as shear spinning, is similar to metal spinning. In shear spinning the area of the final piece is approximately equal to that of the flat sheet metal blank. The wall thickness is maintained by controlling the gap between the roller and the mandrel.

Can a CNC lathe be turned into a spinning machine?
A number of lathe machines can be configured to perform spinning operations, but, specialized training is vital for a maximum production to be realized. Not everybody will be able to change the standard CNC lathe machine into a spinning machine.
What is metal spinning?
The process of metal spinning – also commonly known as “metal turning” or “spin forming” refers to the fundamental fabrication process where a flat metal disc, the blank, is fixed in a spinning lathe to form a hollow part with a circular cross-section. As the blank spins, a roller tool forms it by pressing it against a chuck mandrel, which then duplicates the interior form of the part. The result is a precisely shaped workpiece with a compressed grain structure and a smooth surface, which in many cases may not even require further finishing steps.
What is steel tooling?
Steel: Steel tooling is required to form parts made from stainless steel and other strong metal alloys. Mild steel or tooling steel can be used to fabricate tooling, which can achieve a superior surface finish while still maintaining precise tolerances. Heat treating can also increase the lifecycle of the steel tool.
How has Metal Craft improved its process?
Metal Craft has improved its process by adding robots to the metal spinning CNC production line. These automated robots allow us to complete large scale orders in quick turnaround times, which in turn keeps costs low.
Is metal spinning a good tool for lead prototyping?
Variations on those four basic types are limited only by the designer’s skill and imagination. Spin tooling is inexpensive and versatile and design changes are easily accommodated, making metal spinning a perfect solution for short lead prototyping.
What Is Metal Spinning?
The metalworking process known as “metal spinning” goes by many different names, such as spin forming, metal forming, metal turning, CNC metal spinning, or just “spinning.”
Alternatives To Metal Spinning
Alternatives to metal spinning include hydroforming, stamping, and deep drawn stamping.
Advantages Of Metal Spinning
Metal spinning is one of the most cost-effective methods of forming metal shapes for small-volume and large-volume production. This cost-effectiveness is the highest reason that it’s so popular.

What is metal spinning?
Metal Spinning Overview. Metal spinning may be a versatile and powerful technique for manufacturers and engineers. Many metallurgists only consider its usefulness for creating small batches of artisanal goods. Without metal spinning, motorcycle parts and car wheels wouldn’t be very easy to form.
How does metal spinning work?
Metal spinning can be performed manually or through a CNC lathe machining process.
Why is metal spinning so strong?
This is due to the repeated impact force that these metals are subjected to during the metal spinning process. Less wastage: As compared to other methods of metal forming, metal spinning does not cause any significant wastage of the material.
What is the cutting tool used for metal spinning?
It all depends on the application of the metal to be spun. Cutting tools also form part of the CNC tools. They are essential since some metals may have to be cut after they have been spun. A significant percentage of the cutting tools for metal spinning is made of carbide.
What is the most common iteration of metal spinning?
This means that there are different iterations of this process. The most common iteration of metal spinning is the multipass spinning. This is where the roller of the spinning tool rolls over the disc several times shaping your metal so that it takes the shape of the mandrel.
Why were poles used in lathes?
Here, poles were used to reset the treadle in the lathe, but because this activity reversed the rotation direction, chiseling could only occur during one motion. Pole lathes were easy to supply and really common, even up until the 20th Century. Eventually, iron lathes were constructed for denser materials.
What is the tool used to spin metal?

What is a lathe?
A lathe ( / leɪð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis.
What is the swing of a lathe?
This is known as the 'swing' ("The distance from the head center of a lathe to the bed or ways, or to the rest. The swing determines the diametric size of the object which is capable of being turned in the lathe; anything larger would interfere with the bed. This limit is called the swing of the bed.
How does a glass lathe work?
Glass-working lathes slowly rotate a hollow glass vessel over a fixed- or variable-temperature flame. The source of the flame may be either hand-held or mounted to a banjo/cross-slide that can be moved along the lathe bed. The flame serves to soften the glass being worked, so that the glass in a specific area of the workpiece becomes ductile and subject to forming either by inflation (" glassblowing ") or by deformation with a heat-resistant tool. Such lathes usually have two head-stocks with chucks holding the work, arranged so that they both rotate together in unison. Air can be introduced through the headstock chuck spindle for glassblowing. The tools to deform the glass and tubes to blow (inflate) the glass are usually handheld.
How are lathes sized?
Lathes are usually 'sized' by the capacity of the work that they may hold. Usually large work is held at both ends either using a chuck or other drive in the headstock and a centre in the tailstock. To maximise size, turning between centres allows the work to be as close to the headstock as possible and is used to determine the longest piece the lathe will turn - when the base of the tailstock is aligned with the end of the bed. The distance between centres gives the maximum length of work the lathe will officially hold. It is possible to get slightly longer items in if the tailstock overhangs the end of the bed but this is an ill-advised practice.
What is a headstock on a wood turning lathe?
Woodturning lathes specialized for turning large bowls often have no bed or tail stock, merely a free-standing headstock and a cantilevered tool rest. At one end of the bed (almost always the left, as the operator faces the lathe) is a headstock. The headstock contains high-precision spinning bearings.
What was the first machine tool?
