Highlighting Our New CNC Metal Spinning Lathe & Capabilities

Posted by Helander Team on Thu, Feb 27, 2020

At Helander, we are able to offer innovative and cutting-edge spinning solutions to our customers by regularly expanding our equipment portfolio. We are pleased to announce the recent addition of a CNC metal spinning lathe with machining capabilities to our equipment line. 

Our new lathe is designed to tolerate hot spinning up to 2,000° F and is equipped with thermocouple feedback and temperature control to facilitate temperature monitoring. Our team can now spin form blanks up to 8 feet in diameter and metals up to 2 inches thick, depending on the metal grade and the temperature applied. These aspects and capabilities make the CNC metal spinning lathe ideal for applications requiring larger components, heat resistance, or precise temperature control.

Compatible Parts & Industrial Applications

CNC metal spinning lathes enable an exceptional degree of design versatility and can be used to produce parts for a wide range of industries and applications. The high level of precision and consistency achieved with CNC metal spinning lathes make them especially well-suited for producing complex components for aerospace and defense operations. 

Several examples of products commonly manufactured through CNC metal spinning include:

  • Exhaust ducts
  • Liners for airplanes or spacecraft
  • Tank heads
  • Pressure vessels

At Helander, we are capable of holding tolerances within +/-0.030 of an inch, allowing us to manufacture complex parts with incredible precision. The many metal alloys we work with include titanium; 321 stainless steel; and 7075, 5052, and 6061 aluminum, with material thicknesses ranging from 0.018–2 inches. 

We also possess a hydroforming facility that is equipped to produce parts up to 20 inches in diameter and 10 inches in height. We are able to accommodate orders ranging from a single piece up to 50,000 pieces annually.

The CNC Metal Spinning Lathe Process

The metal spinning process uses friction created by a high-speed lathe to transform metal into spherical or conical shapes. A flat metal disc or tube known as a blank is rotated on a lathe and pressed against a tool called a mandrel to shape it into the requested configuration. With traditional metal spinning methods, an operator manually controls the spinning process to produce axially symmetrical parts.

While manual spinning methods are still critical and widely used within the metal spinning industry, using a CNC machine to control the spinning process offers excellent intricacy, precision, and repeatability in part production. With CNC spinning, a trained machinist programs an operational sequence on a computer, which will then be used to shape the metal workpiece according to the customer’s specifications. 

Benefits of CNC spinning technology include:

  • Quick and efficient production
  • Short lead times
  • High repeatability
  • Wide range of possible designs, patterns, and details
  • Relatively low production costs
  • Low-cost tooling

The Advantages of Metal Spinning

Metal spinning is a unique process that can be used to form complex shapes from aluminum steel, stainless steel, high-strength and high-temperature alloys, and many other metals. Metal spinning is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part and is normally performed by hand or with CNC technology. Spinning metal is an inexpensive alternative to the stamping process, with a quicker processing time. Production prototypes can not only be designed on the fly but most changes to a design can be accomplished without added expense to the customer.

Because spun parts have no seams, they can withstand higher internal or external pressures. This is due to grain structure of the metal spun part, which is realigned, improving the metallurgy, as well as improving the tensile strength of the material. This also allows for a lighter gauge material to be used, saving on material cost. Some examples are scuba tanks, CO2 cartridges, and oxyacetylene tanks. Other products that can be produced by metal spinning range from small hardware items made in large quantities, such as metal tumblers and automotive components, to large components for aerospace applications. Metal spinning can be used to cost-effectively produce single or a small number of parts out of expensive materials, such as platinum, or large quantities of components of low-cost materials, such as aluminum. Cost savings are further enhanced from the inherent smooth finish that spinning produces, often eliminating the need for additional machining. Other advantages are very low tooling compared to stamping, as well as very short setup and changeover times. The process is also eco-friendly with less waste being produced.

Metal spinning provides an economical solution for products that require structural integrity. A wide range of shapes can be produced with relatively simple tooling. Here’s a video demonstrating the process at work.

 

Description

Carried out by the application of an even, force applied to metal uniformly by rotating the metal at very high rpm’s.  Metal is deformed evenly in the metal spinning process without any wrinkling or warping.

Equipment Used

Can be performed by hand or by a CNC lathe.

Material Used

Virtually any ductile metal may be formed; ranging  from aluminum or stainless steel to high-strength, high-temperature alloys.

Restrictions

Diameter and depth of formed parts are limited only by the size of the equipment available.

Advantages

  • Several operations can be performed in one set-up
  • Changes in part design can often be made through changes in tooling, particularly if the change is a reduction in size
  • Smaller amount of waste products produced
  • Produces products without seams (part can withstand higher internal or external pressure exerted on it)
  • Assures a higher degree of reliability on parts that have a structural function
  • Avoids warping
  • Lead times are usually shorter compared to other tooling methods
  • Low-cost tooling
  • Depending on volume, tolerance, and capability of the part, tooling material options include tool steel, engineered plastics, and wood
  • Improves the metallurgy by realigning the grain structure of the metal.  Tensile strength is improved, allowing lighter gauge material to be used in the same application.

Industry for Use

Volume

Typical production runs of 1,000 pieces or less

Helander’s Fabtech Canada 2012 Preview

Posted by Samuel Ibrahim, Jr. on Fri, Mar 09, 2012

One Fabtech show in a year is quite an event. But all the metalworking expo action isn’t in Chicago. This year’s Fabtech Canada 2012 expo, happening in Toronto from March 20 – 22nd, 2012, promises to be just as exciting and informative as its stateside counterpart. We found the January show to be overwhelmingly helpful, and won’t be attending Fabtech Canada this year. We will, however, point you in the direction of some of the most promising panels and events at the conference.

Don’t Miss: The Keynote Speaker, race car driver and TV star Andrew Comrie-Picard. Andrew will be discussing his varied career – from attorney to racer to TV-host-of-all-trades – and talking about thinking outside the box in manufacturing, from materials to processes. One way to do that? Look into hydroforming instead of other processes.

Get Involved: Wednesday’s Toen Hall discussion will allow you to pose some questions or share some answers, recognizing that the expertise at Fabtech Canada is among all attendees, not just speakers.

Look Ahead: Thursday’s presentations will focus on the future of welding and manufacturing as a whole, including a talk on using technology to close the machining skills gap. In the pursuit of young, talented engineers and machinists to fill and ever-growing number of positions, there are a number of ways to find them. One of them? Social media, meeting them on their level. This is just one of the many reasons Helander has initiated our extensive social media outreach.

We hope to hear from any and all Fabtech Canada 2012 attendees! Share your stories or advice here.
