Personal Experience with Jet 321862 GH-2680ZH Lathe with Newall DP700 DRO and Taper Attachment

Having worked with several lathes throughout my career, my experience with the Jet 321862 GH-2680ZH stands out for several reasons. From the first day, this machine made an impression with its robust design and user-friendly interface, both of which have significantly streamlined the workflow in our shop.

Daily Operations and Ease of Use

On a typical day, I rely heavily on the digital readout (DRO) system, the Newall DP700, which is a game-changer for achieving precise measurements without recurring to manual gauging. This accuracy is crucial for the bespoke parts we manufacture, which often have tight tolerance requirements. The clarity and reliability of the DRO ensure that we consistently meet the specifications demanded by our projects.

The rapid traverse feature is another aspect that I find immensely beneficial. It allows us to move the carriage and cross slide quickly along the bed, which is particularly useful when working on larger pieces or when needing to adjust the machining start point. This not only saves time but also reduces the physical strain associated with manual adjustments.

Performance Under Load

The GH-2680ZH is equipped with a 10 HP motor, which provides ample power for all our operations. Whether we’re turning large steel shafts or delicate bronze sculptures, the machine operates smoothly without any signs of strain or overheating, thanks to its effective coolant system. This consistency is something I’ve come to rely on, especially during long production runs.

Practicality and Support

The assortment of chucks and the inclusion of both a steady and follow rest have broadened the range of projects we can handle. This adaptability is crucial for a custom shop like ours, allowing us to take on diverse projects without needing additional equipment.

In terms of support, Jet’s customer service has been prompt and helpful on the few occasions we’ve needed assistance. Whether it was a question about maintenance or a request for spare parts, their responses were always timely and effective, minimizing downtime.

Tailstock and Quill Operation

One feature that I find particularly valuable, and that I often take for granted, is the robust design of the tailstock and quill. It’s designed to be sturdy yet easy to adjust, which is critical when working with long or awkwardly shaped workpieces. The smooth operation of the tailstock enhances our ability to maintain precision over the entire length of the piece, which is often a challenge with less reliable equipment.

Threading Capabilities

Threading is another area where this lathe excels. With the capability to easily switch between 48 inch and 22 metric thread pitches, the machine allows us to cater to a variety of customer specifications without significant downtime for setup changes. This versatility is a huge advantage in a commercial setting where client requirements can vary dramatically from one project to the next.

Durability and Reliability

From a durability standpoint, this lathe has withstood continuous use without any significant issues, which speaks to its solid construction and quality engineering. It operates just as smoothly today as it did on day one, despite the high-demand tasks we regularly put it through. This reliability means I spend less time worrying about machine downtime and more time focusing on production and quality control.
