Please keep in mind one table cannot possibly cover all possible variations of Milling Machines DRO PROS always recommends measuring your particular machine's travel
Glass Scales:
Digital Scale Size refers to the part number. In other words, the smallest scale (also known as a linear transducer), we carry is referred to as a 100mm digital readout scale.
Obviously, you want to pick a digital scale with enough capacity to allow the reader head to at least physically travel to the limits of your particular machine. While our guideline is to recommend allowing ~1/2" on either end of the scale for clearance, you may decide to leave less room. One instance where it might make sense to reduce the end clearance is when you're installing a scale on a lathes cross slide.
For example, if your lathes cross slide travel is 6", our chart would recommend using a 200mm digital scale. But an experienced installer might very well choose a 150mm linear transducer instead, realizing that the end clearance will be less than what we recommend. Still, note that the overall maximum scale travel of a 150mm scale is ~ 6.9", which is more than the machines travel of 6". The installation should be fine, but the installer must realize when choosing a mounting point for the readhead that the end clearance is less than what we recommend. So how far can you take exception to our recommended clearance of 1/2" on either end? As far as you feel comfortable. Just realize, the less clearance = the more likely the readhead may run into the end of the digital scale. In other words, be careful!
How to measure your machines travel, or capacity Why do we have to measure our machines capacity? Why can't we just use the stated travel specifications from the manufacturer? Won't all machines of the same model type have the same capacity? Surprisingly, no. Manufacturers typically overstate their machines travel, especially for the Z or vertical axis on milling machines. Typically the travel is measured without a drill chuck or collet in place, sometimes even without the spindle! Further, additional accessories like power feeds may sometimes limit your machines travel to less than original spec's.
Here then, is the easiest way we've found to measure your machines travel: With the machine off, position the machine to the far end of its travel. With a grease pencil, make a mark across where the movement and stationary surfaces meet. Next, position your machine to the opposite end of its travel limit, then simply measure the distance between the marks. Congratulations, you've just measured your machines true capacity!
Length simply refers to a scales actual physical outside dimensions or overall length. There is 3" distance from the center of the reader head to the outside of either end of the scale. Therefore, every scale is physically 5" longer than it's maximum capacity. For example, our 100mm scale has a capacity of 3.9" but is physically 9.9" long. Likewise, 600mm scale has a capacity of 23.6" and is physically 29.6" long. Still confused? Don't worry about it - Just give us a quick call and we'll work you through it!
Price. Most likely you'll be buying our scales with a kit. Our 100mm - 1000mm scales are included in the price of the kit and there is no surcharge. Simply tell us what size scale you'd like and we'll send the correct length digital scale. For scales greater than 1000mm (our oversize scales), there is a surcharge based on length when purchased with a kit (see the chart).
Glass Scale Accuracy:
Advanced Optical Measuring Systems (Glass Scales)
High Noise Immunity & (EMC) Design The slide carrier of the GS series digital readout scales uses a five bearing design. The optical grating linear transducer has been proven as the most reliable system design in today's market. The glass grating slideways are lapped, and JIS standard P5 grade bearings are used to achieve smooth and accurate movement and long working life.
Double Seals Design The plastic seals of the GS series digital readout scales use an innovative material to offer superior oil resistance, high elastic recovery properties and durability. Carefully designed lip geometry offer low slide resistance.
100% Laser Calibration All glass grating linear transducers are individually inspected and calibrated by Easson's in-house laser calibrator to ensure 100% accuracy.
ASIC Interpolator ASIC Interpolator is built-in inside the GS Series Glass grating linear transducer to facilitate increased resolution of the grating. All frequency multiplication is implemented 100% by hardware phase shifting inside the ASIC interpolator to minimize the real time measurement error. Additionally, error drift caused by environmental temperature change is minimized by constructing all resistor ladders for phase shifting with the same piece of semiconductor.
Industrial Standard Output Signal Interface Only the industrial standard TTL digital signal output is available. Interface is the industry standard 9 pin DSUB9 connector.
Glass Scale Kits: At DRO PROS, we only sell true five bearing glass scales with our readout kits, and with over 70 different size scales to choose from, we fit your machine right! For .0002" resolution scales up to 39.3" in capacity (models 100mm - 1000mm), the scales are included in the price of the kit and there is no surcharge. Simply tell us what size scale you'd like and we'll send the correct length scale. For scales greater than 40" capacity (our oversize scales), there is a small surcharge based on length when purchased with a kit.

Why does DRO PROS post their digital readout part prices online when other companies don't? That's because if you were to find out what other companies are going to charge you for parts when you need them, you might not buy their digital readout kit in the first place! At DRO PROS, we're proud to show off our low part prices. Go DRO PROS!
Why should you buy from DRO PROS? We speak English - We answer our phones - Same day shipping Veteran owned, Veteran managed - and proud of it!
Our goal is to make customers for life. We feel that, in the long run, treating customers right will yield much more than simply "going for the sale". In accordance with that, we have attempted to pass on some ideas to help you, the customer, in completing your purchase decision:
Price. Probably the most talked about factor when buying a digital readout. Price can also be the most misleading, and perhaps worst way, to judge a digital readout kit. We've all heard the old adage, "You get what you pay for." Before the internet, it was true, price did generally correlate directly to value. But that was yesterdays economy. All resellers obtained their goods the same way, and therefore incurred the same costs. In today's economy, the market has changed drastically. At DRO PROS, we import and sell directly to you. Unlike our competitors, we do not have Western and Eastern sales divisions and multi layers of management to support. One location, one cost, and the savings get passed on to you!
Intuitiveness or "Ease of Use". Probably the most important, and hardest to determine factor when buying a readout. Think in terms of after the sale. Even if you get an absolute 'rock star' bottom line price that would make William Shatner proud, if the digital readout is not user friendly, you still didn't get a 'deal'. The whole point of getting a digital readout is to make your work easier and more enjoyable. If the digital readout is poorly designed, too complicated, if the display isn't bright enough, or in other words is 'user unfriendly', you'll regret your purchase decision every time you turn it on. It simply won't matter what you paid, it's not worth it!
Support. Most likely the second most important, and perhaps most overlooked factor when buying a digital readout. Imagine trying to reach a technician when you've bought a digital readout from an overseas reseller! Yet every day, people "save" $50 and buy products on eBay without stopping to think what will happen when they need service or tech support. Some digital readout resellers don't even publish a phone number! While our competitors continue to pare down or even totally eliminate their customer support, we continue to expand our Customer Service. Our Video Tutorials are the best in the industry, and are available free for you, our customers. Our tech help is the best in the business - our techs all know our readouts inside and out. Nobody knows digital readouts like DRO PROS!
Warranty. DRO PROS is proud to offer the industries safest, longest, 6 year warranty on all of our Electronica magnetic scale kits. All of our DRO PROS brand glass scale kits come with a full 3 year warranty, and our EASSON kits come standard with a 1 year warranty. DRO PROS brand warranty claims are handled directly by DRO PROS. No run-arounds, no hassle! Something not working as expected? Call us, don't get redirected overseas like the other guys!
Parts. Can you believe some resellers don't carry parts? That's right, buy from the "other guys", break a scale, and you get to replace the entire digital readout kit! Don't assume you can just go buy a different brand scale, either, because most manufacturers use different connectors on their scales. If that wasn't enough, even among those with a common connector, such as a DB9, most are hard wired differently. Finally, don't overlook the cost of parts. At DRO PROS, an 800mm replacement scale will cost you $197. A similar scale sold extensively by a European company will cost nearly $700! Finally, we have a massive inventory of parts, so rest easy - a replacement part is only a phone call away!
The Best Value. We literally search world-wide for the best value digital readout products on the planet. If there was a better digital readout package to be sold, we would be selling it. Yes, we've seen cheaper units on eBay, but there is a reason they're cheaper. Think poor quality, no parts, no manual, non-existent customer service, poor product fit/finish etc.
Customer Service. We pledge to never "over sell" you on a product that won't work well for you. Our philosophy is to try and save you money and get the best value kit tailored to the machinery you have. Many of our customers are surprised when we recommend against buying a more expensive brand. Again, our philosophy is to build customers for life. Give us a call and let us save you money!
Shipping. Most orders ship the same day, the next at the latest. We do not 'drop' ship, we have our own massive warehouse of inventory right here on site. We use FedEx, you'll get a tracking number emailed to you immediately, and we cover all shipping insurance automatically.
The Company. DRO PROS is a veteran owned, American company. We enjoy selling quality products at competitive prices. We believe that providing the best customer service is the key to success. No other company spends more time on the phone with customers than we do. Even in a down economy, our company continues to thrive and grow. We look forward to earning your business!
The Bottom Line. Our line of digital readout's are simply the most user friendly readouts on the planet. Because of our direct marketing structure, they're also extremely affordable. Coupled with our extensive customer service and affordable parts, our Digital Readout products are simply the best value on the planet.
