DRO for a mill.

[wm460]

I am looking for a Dro for my mill, and more I look the more confused I get. I have a Sinpo 2 axis Dro 2L on my lathe and thought about getting a Sinpo 3 axis Dro 3M for my mill.

Sinpo 3 Axis Digital Readout for Mill Milling Machine Complete DRO Kit | eBay

Which is $ 661.10 plus postage also looked at the

HXX 3 axis mill DRO system 3 axis digital readout and 3 piece 0 1000mm linear glass scale for lathe milling grinder EDM machine-in Other Machinery from Industry & Business on Aliexpress.com | Alibaba Group

This is $394.26 plus free postage.

What is the difference between the Sinpo and Sino DRO's?

Is there any other type I could be looking at?

Mark, I have a small Optimum mill, and I got a Delos 3 axis DRO from the manufacturer in China. They supply a mini glass scale which is less cumbersome on small mills and lathes. It is a top quality DRO, delivery was 3 days and from Memory about the $ 400 Australian, so US dollars would be less.

Thanks Norm, I will check them out, What size is your mill?

Mark, my machine is a BF 16v model. Norm

What is the difference between the Sinpo and Sino DRO's?
?

Sino and Sinpo are the same product with a bad reputation
I got mine direct from China and no problem at all adresse supplied with email

 

[Dr Jo]

I have 4 Sinpo DROs and they have been excellent over the 5 years I have owned them. I also have a Newall and two Machine DRO units.

Luc: why do you believe that the Sinpo have a bad reputation? They have been excellent in my experience and I would willingly buy another.

Hi Jo
when I started shopping for DRO`s for both my 2 mills and 3 lathes I did a lot of research. Quality, price and option was my mane issue.

Many supplier advise me NOT to go with Sinpo or Sino because of their very poor quality of product. I myself never had any of these product, so it`s more a mouth to mouth then any thing else.

After talking to many supplier and asking them WHY NOT Sino , specially they are ALL Made In CHINA. and there answer was `SINO are made to CHINESE specification, and are known to be poor.

Diltron is also made in China but to the US standards, wider PCB board track thicker board also, as far as quality of the transistors and resistors IT`S all BS unless you are going to Army standard.

Diltron makes DRO`s for 30 reseller across the world and one of them is SHARS

then again if you pamper your stuff like I do Sino could have work for me
Cheers

I'll vote for Ditron too. I bought it after I saw a slimline scale of theirs in Hare and Forbes who are about the only supplier of machine tools down here in OZ. I needed the slim scale on the crossslide. The other so called slimlime scales are not if you check their dimensions. Ditron is much nicer than the DRO on my mill. Ive forgotten what I paid but I know it was very affordable. Also sourced off alibaba

Hi Rod, there are plenty of machine tool suppliers, but Hare and Forbes are the major one for the home workshop as well as to general industry.

I have Machine DRO sourced SINO DROs on my lathe and mill, the mill DRO has been running constantly for around 10 years, an electrolytic capacitor failed in the Mill unit a few months ago, 70 pence and a visit to Maplin later and it's running perfectly again.
Maybe quality varies for units sourced directly form China?

I am in the same position as Nick above, but have never had a single glitch with any of my Sino units (3 displays, 7 read heads).
Have yet to try out my Sinpo units, still in the process of fitting them.

I personally think it is a lot to do with one upmanship, all it takes is one person with more money to spend and then to spread rumours about bad quality in the hope they can justify spending too much on their system.
I worked in a high precision machining industry (making prototype hard drives, first ever 3.5" one), and have seen all the expensive DRO's failing rather regularly and miserably.

My systems are defintely one upmanship, but only against the scale type, which I really suffered with for many years.
I then bought what looked like a reasonable system at a reasonable cost for use in a home workshop, despite setting it up as a high precision jobbing shop at one time (Sino & Sinpo), and haven't look back since.

As you may know, I don't mince words, I'm just telling how it really is.

Yeh, I know but I don't know of any other in Brisbane that has the range of gear on display in one site. Up here they moved their workshop across the road into a building double their old one and kept the old building for the store. If you buy something, you often have to duck across the road to pick it up. I have noted they are much more serious about the industry side of their business in the last 12 months or so. Much bigger gear and much of it is European.

The way they are going, they will be supplying very serious machinery to industry soon enough. With the upcoming closure of the automotive manufacturing, I think that a lot of the machine suppliers who only sell the one brand will call it quits and let others take the agencies.

What is the difference between the Ditron D60-3V and the D60-3M ?

Not sure but I think the V has additional options for an EDM. machine.

 

[tombstone]

Newall B60 all day long too many gimmicks you won't use on Chinese units

I have the D60-2V on my lathe. 1 micron scales were an extra $10 or so and I went with them. The slimline scale DC10F is very compact so consider the space you have and it is not a big upgrade either if it is required. You may need it on one axis. I used it on the crossslide and really would have been lost without it.

As far as scale length, you need to measure the actual travel on each axis, buy a scale with travel a bit longer and then make sure that you have the room to mount it after allowing for the ends. My crosslide travel is limited by the scale but I positioned it so it does not matter.

I can vouch also for the Delos. I have installed it recently and Im very happy with it. Just check that you get the mini scales. It requires less space for fitting.

I had a reply from Ditron.
I said that I want scales for the Z axis and also ask for prices for 1um resolution scales also prices for the slim scales.

I measured the travel on my mill on the week end and I got the following measurements,

X 530 mm
Y 180 mm
Z 400 mm

What length should I go for?
