Why Choose a Vertical Turning Lathe

Vertical Turning Lathes

The vertical turning lathe (VTL) or vertical turning centre has been a well-adopted technology for many generations. Unlike its horizontal counterpart, the VTL is configured in a different axes to provide application benefits for a variety of parts that are not particularly suited to horizontal lathes.

What is a Vertical Turning Lathe?

In contrast to the horizontal lathe, the vertical turning lathe is configured with a machine bed that sits above the powerful driven motor. Components are clamped to the machine bed and the spindle motor below drives the rotary table and the components clamped to it. Sitting above the table is a bridge-type design with a RAM cutting tool station that lowers the cutting tool to the workpiece in the Y-axis to undertake its material removal tasks.

Since its inception, the VTL hasn&#;t stopped evolving. New versions of vertical turning machine tools incorporate many of the productive technological innovations found in horizontal turning centres. Essentially, a vertical turning centre configuration takes a traditional lathe and stands it on its end.

The design of the VTL provides several important production and cost benefits, especially when machining large and heavy components and castings. The traditional VTL is perfect for turning heavy parts, brake discs, pump housings, aerospace and power generation parts and much more. But why?

What are the benefits of VTLs?

The vertical turning lathe is typically a large ram-type machine that can also be known as a vertical boring mill (VBM). An indexable tool turret head is what often distinguishes traditional VTLs from VBM variants. The machines are not typically high-production machines. The forte for the vertical turning lathe (VTL) is heavy-duty and high-power cutting of medium and large parts. So, what are the key factors when considering a VTL?

With parts that are often large in dimensions and weight, loading the components onto a machine bed as opposed to loading into a chuck on a horizontal turning lathe is a fundamental benefit. The gravitational pull of heavy parts on a horizontal machine can create issues with lifting and loading, set up and clamping, concentricity and subsequently clamping forces can be compromised by the centrifugal forces created by turning heavy components. All of this is eradicated with a VTL whereby the component sits on the machine bed and the subsequent clamping devices can be minimised. The result of clamping components on a bed is that stability and rigidity are increased and users can undertake heavy-duty cutting with ease. This increases productivity rates, reduces cycle times, improves tool life and surface finishes. Furthermore, by removing material in the vertical axis, chips automatically fall away from the immediate cutting area.

To undertake heavy-duty cutting, the vertical turning lathe often tends to have extremely powerful high-torque spindle motors that rotate at slower speeds than horizontal turning centres. This suits heavy-duty cutting on a stable and robust platform that is ideal for maximum material removal rates (MRR). The evolution of the VTL means that the vertical designation is now more suitable than ever for small to medium parts as well as the very large parts. Additionally, VTLs have multiple configurations for stationary and driven tools in multiple axes as well as automation that can increase the scope for these machines. And of course, in a world where floor space is an increasingly critical factor to engineers, by turning parts in the vertical axis, the VTL requires less floor space than the horizontal turning lathe. If you are interested in the benefits of the VTL, GM CNC has a range of options available for you to review.

A range of applications and technologies may seem old-fashioned but they are needed to make some of the best parts. This is very true for VTL Machining companies in Chennai in order to provide the best service for their customers. A traditional VTL is a classic example in this class of technology. However, there are newer versions of these tools and they incorporate productive technologies and innovations that are found in horizontal turning centers. Gayath Heavy Engineering Private Limited uses these disposable machines with various advantages.

Usage in a wide variety of castings

Equipment with good machining capabilities or companies that outsource the entire machining process can reap huge benefits from VTL technology. The VTL configuration mainly uses a traditional lathe for the manufacturing process. This unique design provides a wide array of production methods, and cost reduction and is particularly suitable for castings like brake discs, aircraft parts, pump housing materials, and many more.

Here are some of the advantages of VTL machining companies in Chennai

The vertical turning lathes are huge and ram-type machines. They are also called vertical boring mills or VBM. These lathes cannot produce huge quantities at the same time; however, they are ideal for cutting medium-sized or large parts and are heavy-duty.

• A major advantage of a VTL machine is it easily handles heavy workloads and pieces and can be set or held in a particular place for machining. The benefit of using VTL is only a minimum amount of hard clamping is required.
• The vertical turning lathes use a spindle or fulcrum to load and unload on their own. They have multitasking abilities and which makes them efficient processing units to produce clamps and chucked parts.
• The vertical turning lathes give the foundries a machine shop that has the ability to cut heavy and big castings.
• This tool can be indexed distinguishing it from VBM&#;s (Vertical Boring Machines).
• The VTL machines also use a design that rotates using a rotating table in order to support the workpiece and bridge construction to carry the X-axis.
• When it comes to productivity, the VTL improves the cycle time to a large extent and enables shops with aggressive cuts.
• In addition to these, it comes with high horse power and torque that is required to cut heavy metals that are difficult to cut otherwise.

The role of VTL in VTL Machining companies in Chennai

This machine uses a table drive system and ram that are capable of delivering high horsepower and torque used for heavy hogging. It also incorporates the advancements that are demanded by machine tool users across industries. Some of the features include thermal stability, automation, reduced set-up time, and a smaller size that occupies lesser floor space. In addition to these, they are mounted with cameras so that operators can track the operations even from remote locations.

Conclusion

VTL&#;s of Gayath Heavy Engineering Private Limited has always been very useful for machining companies in the large picture. This is because of gravity that enables keeping the workpiece together rather than creating an opposite effect to the clamping procedure. It is still being used by construction, marine equipment manufacturers, energy sectors, and other sectors where these machines are commonly used.
