Ways to Buy the Right DRO for the Lathe

Ways to Buy the Right DRO for the Lathe

If you are an individual who has never used a DRO before, finding the right might be a bit challenging for you.

You will come across numerous digital readouts available in today’s market, with a price of hundreds or thousands of dollars. 

When you want the best-quality DRO for lathe, there are several ways that you need to follow that will lead you towards the right one.

That is why I have listed some of the ways through which you can get yourself the best DRO. Check the information below.

1. The Resolution And Accuracy

Digital readout devices stand out as precious measurement devices. The overall resolution and accuracy within these devices are the most important characteristics.

The resolution and the accuracy heavily depend on the scale selection. But on certain occasions, many individuals overlook the fact that the console itself can cause plenty of errors.

This type of error takes place in two ways. Firstly, when some low-end DROs use less expensive and older micro controllers, which give birth to errors during division.

Lastly, when there are missed pulses within the scales, which leads to a build-up of error. So, when you are shopping for a DRO, make sure to check whether the unit can handle the expected traversal speed.

2. The Usability

One of the biggest reasons to add a DRO to your lathe is to enhance the usability of that particular machine. But this is a neglected parameter when it comes to the digital readout device.

The digital readout unit must carry a consistent and intuitive user interface. You will come across some low-end DRO that has the menus and user interface cobbled up together to check the sales box within the sales brochure.

During the time of your purchase, you must choose a DRO or a digital readout that shouldn’t be much confusion and must carry a natural feel.

Take my advice and first download and study the manual of the DRO unit. You can check whether the functions that you wish to use are accessible or not.

3. Protection from Dust

Protection from Dust

All DROs or digital readout units are used within a hostile ecosystem of a machine shop for which they are subjected to grime and dust. To survive in all environments, go for a DRO that comes with some level of protection.

If you have a flood coolant that needs to be used regularly, it will be much better to have IP65 protection. Otherwise, IP68 or IP67 will also do.

Frequently Asked Questions

1. What are the Types of DRO Interfaces Available in Today’s Market?

The digital readout units have been around for over seven decades but underwent numerous changes. These changes have given birth to various interfaces, such as Basic 7-Segment DROs, PC Based DROs, LCD Based DROs, Tablet-Based DROs.

2. Does the DRO Require to be Shock and Vibration Resistant? Why?

In short, yes. It’s because an average digital readout is subjected to vibration when used during the machine.

When the circuit present inside the unit does not carry vacillation resiliency, it might fail to function because of a cracked solder joint. That is why getting a DRO with vibration and shock-resistant features is highly important.

3. What Will the Digital Readout Help Me?

The DRO or digital readout will help in simplifying your work, save time and energy. It will also help in lessening all the costly mistakes and enable you to deliver exacting and accurate parts.

When there is no DRO system, you have to count all the handwheel revolutions that will enable you to determine the exact of the tool.

Final Words

When you add a DRO to a lathe will stand out as an excellent investment. Even though your budget is an important factor, when buying the DRO make sure to check the usability, resolution, accuracy, and many other things.
