FAQ:

Glass Scale vs Magnetic Scale


A simple number will tell you all. 99% linear scale is running on glass now, so magnetic scale must have some fetal disadvantage. Sony was only few companies to make magnetic scales before, Sony killed it 10 years ago. Ford killed focus, Chevy killed Cruze. There must be some reason. Ford and GM claim unpopular and no demand. So I guess Sony has the same reason to kill magnetic scales.

Now Few Company spread rumors on glass scale, how bad the glass scale is, and it's not water proof, doesn't last and so on. It's funny that those companies were selling glass scale for years, now they try to convince customers stay away. Do they really contradict to themselves? In another words, the glass scale they're selling may have some problems, and all those bad words above should apply. Therefore, for all customer who bought their glass scales before should go after the seller and ask for compensation because they didn't disclose the truth about their products when they sell it. Before they push glass scales sales, now they say glass scale is bad. It’s a joke. By the way, I sell glass scales since day One, never ever changed.

The truth on glass scales is far more accurate than magnetic scale. You may ask both type scale labeled as 5um or 2 tenth, so what's the difference. Keep in mind, 5um or 2 tenth is resolution, not accuracy. Resolution is what you can read from display unit. However, the real accountability or repeatability is called accuracy. Both glass and magnetic scales have error if you don’t calibrate. On glass scale, it’s called linear error, which is very easy to correct, however, the error on magnetic scale is called non-linear error. For example, glass scale linear error means the error is insistent, it’s the same. If error is 2 tenth off on 1” travel, then if you slide 10” travel, the error will be 2 thousands, which is 0.0002”x10 is 0.002”, error is increase proportionally, then you enter in one fixed compensation ratio to fix that. However, on magnetic scale, error could be any number in different travel range, example, 0-1” travel, you may see 2 tenth off, then 2-3” travel, you may see 3 tenth off, then 3-4” travel, you may see 1.8 tenth off. Therefore, on the same 1” travel, the error is non-insistent, so it’s really hard to compensate, as a result, when you’re running certain function on the display unit, you may see difficulties. If you don’t care, you don’t care, but I think most customers prefer reliable, accurate and easy calibration scale to begin with.

2nd, on water and dust poof, If you pour water or spread sands of dusty directly to both glass scale and magnetic scale, none will last, that’s the truth. On the water proof, we should call it splash proof, which means wet splash may goes into scale. So both glass scale and magnetic scale are sealed against wet and dust. Glass scale usually sealed in 2 or 3 layers and magnetic scale has very thin seal.  Also, don’t forget that both scales come with shield cover, what those covers for, it’s for shielding scale away from splash and dust. When you mount scale, usually it’s face down, not up, ask yourself, is water going down or going up. Water 100% is going down, scale cover is face down, scale is face down, so the water will flow over shield cover and drop on the floor. People are running glass scale by water jet and edm all the time, if not water proof, how can glass scale handle it.

3rd, weather scale should be cut or not. It’s an interesting question. On the standard knee mill, like bridgport or off brand Bridgeport or clone, there are enough space on the machine to mount scale, so you should get longer and taller scale to mount, who wants to cut. The only machine you may need to cut to install is those small mini or bench type mill, those are toys or hobby. I focus on industrial machine more than home hobby toys. I don’t sell toys.  On the lathe, cross slide height space is limited, then I have slim scale to overcome, slim scale height is even less than magnetic scale. On 12 or 13” or even smaller lathe, you may need slim scales on the cross slide, but on 14, 16 and 18” lathe, the space is high enough and so I suggest you go with normal height scale.

Finally, well build glass scale like mine last years as well because the glass is commercial grade thick glass. I don’t want to post any fake numbers on the life span, like 1 year, couple years, 10 years, 20 years or maybe life time. Last or not, only customers can tell. I don’t want false advertise or misleading. My goal is that when you retire and pass the machine to next generation, my scale on the machine is still working.

To be honest, I dislike many people, that in order to push their minority or unpopular products sales or couldn’t beat my sales, then they spread rumors on majority and popular items all over place. Sometimes, they contradict to themselves. The truth is that majority of scales on the market are glass scale, 99% or even higher. More and more companies are dropping to make magnetic scales. To be clear, very few companies even making magnetic scale at beginning, and now they all dropped out, so there must be a reason.

Americans don’t know how to drive stick shift now; auto tranny is in 94% cars. In order to sell standard transmission car, you can’t say automatic transmission doesn’t last. Auto tranny can go over 200K miles also. The friend of mine, his Toyota Tacoma truck was wrecked after 400K with original engine and auto tranny. So let’s be clear, scale last not, depends on how well it built, also depends on how well you take care of it, which is the same on the car truck transmission, how it build and how you take care is the key.

Why tpactools dro lasts longer than majority of import units, which has been proven for years.

Good question, the short answer is that my unit is built for industrial, not a home hobby toys. Commercial and industrial company is running machine all day long, so they need a reliable unit on the machine. However, home machinist runs once in a while. If the unit can handle industrial well, then it’ll handle home shop like piece of cake.


Can you tell more details how your unit is well built?

Here are few details, 1st. the glass inside scale is thicker and stronger, glass is a key to a glass scale, it’s very easy to understand. Look around, see the glass on any office building, then compare with the glass on your home window. Also, make trip to Home Depot, and look at different window with different thickness glass, then you’ll know something. 2nd the bearing sliding on the glass, my bearing is Japanese. If you’re in bearing business, then you’ll know what I’m talking about. 3rd, data sending unit, people called reader head, which sending data from scale to the display unit via long data cable. That little piece motherboard and all electrical parts in the reader senor head has been tested long enough before production, and all electrical parts are from quality supplier as well. 4th, when I place order, I don’t order common unit, which is the same like others. I usually ask supplier to make the purchase order according my special requirement. I can’t tell you all because some are commercial secrete or intellectual property, which is the key to a business and products.


Is your display unit made of metal or cheap plastic?

All my display unit from 1 to 4 axis are made of metal, so it’s metal case, heavy and durable. If you never see what metal case,  you may think plastic case is pretty good, once you see metal, then plastic looks like a toy and feels like a toy. I don’t sell toys.


Is 0.0001” or one tenth scale necessary?

Usually rookie will ask this question. Here is number break down. For manual Bridgeport and lathe, maximum accuracy you can reach is about 0.0005”. I don’t think you can make parts with 2 tenth tolerance on a 50 years Bridgeport. So you only need scale accuracy to match 5 tenth or a little above to cover Bridgeport. Keep in mind, 2 tenth is less than half of 5 tenth, which means 2 tenth is more than double that Bridgeport accuracy can reach, so it’s accurate far enough. Now you may argue with me, 1 tenth is even more accurate, yes I agree. However, 1 tenth scale is much more difficult to make, unstable, and more important is that 1 tenth scale has much less lift span than 2 or 5 tenth scale. So why do I pay more for the something I don’t need. Lathe is the same, whatever cross slide or carriage travel, accuracy is far away from 2 tenth, so 0.0002” scale will cover perfectly. Keep in mind, 1 tenth scale is not installed on mill or lathe, and it’s installed on some special measuring device or equipment in the lab, plus they don’t run those super precision devices all day long. I haven’t find any supplier can make decent 1 tenth scale reliable, if you see cheap 1 tenth, don’t buy it, you’ll suffer more than enjoy from long run. I carry 2 tenth only, and 99% vendor and supplier are focus on 2 tenth as well.


Warranty?

Since mine is well unit, so I don’t worry about breaking down in short term. Customer trust me, and I’ll return trust with quality products. Usually, there are two cases why scale is break down. 1st, products are defect, which is less likely happen to me. However, if it happens, I’ll keep my words, and warrantee for 5 years for entire unit, it includes everything you bought, display unit and all scales, this case will be my fault. 2nd, if it’s customer fault to damage the scale, few examples couple be, scale is a little short, not cover entire travel, then the scale is over run, or scale is not mounted in the center of table, then over run from center to the end, or people who run the machine never take care and clean scale, I called it abuse. If all those happen, let’s be clear, those are not seller’s fault, I’ll provide option of free repair if repairable or replace with a little cost. In order to avoid all of those happen, make sure measure table dimension before place order, as long as you tell me correct table length, then I’ll send you scale that long enough to cover travel on all axis. Also, make sure all scales must be mount in the center of the table, finally, don’t show me any signs of abuse, so please calibrate scale before initial running, cover up and clean scale once in a while, if you take care the scale, then scale will return you with longer life span. Same like oil change on your car, if you abuse engine and tranny, don’t change oil on time, what’ll happen.


Do you over descript products and let customer write fake reviews?

People are paying attention on item description and reviews when buying online. I know better than anyone else. Those fake reviews and untrue descriptions may drive sales up in short term, however, when customer discover the truth, they’ll hate products and seller like you never believe, sometimes, could end up with a lawsuit. I call those sellers are liars who cheat on review and descriptions. Keep in mind, liar will be a looser. So as a seller, I’d better be follow all rules and regulations. There is another case, which happen quite often, and we can’t call it fake review. Customer bought it, receive and open box, played few days and really like it, then write 5 star reviews. However, short term joy doesn’t last long, and item break down short after that. On the dro and glass scale, it happens very often. People bought cheap unit, saved $200 to $300, really like it, write good reviews, then scale break down in couple month or less than a year. I don’t call it fake review. My point is that industrial products is different from consumer items, so customers really have to run it for couple years, then they’ll know if it’s good or bad, last or not. there are too many victims here, enjoyed cheap unit for couple month, then break down and come back to me finally. So my words to those cheap guys are, buying good and reliable products at the 1st place. Keep in mind, price is not overall of a business especially on industrial products.


How to buy correct unit to fit my mill or lathe?

Look at very top page, there are few size options, like 9x36 table, 9x42 table, 9x49” table. Make sure you see the word table, which means 9x36 is table dimension, table is 36” long by 9” wide, and it’s not length of scale.  So all your need to do is to measure table length, then choose correct option above before add to cart. Once your table dimension is correct, I’ll send you long enough scale to cover all travels. When you receive and start installation, make sure mount scale in the center of the table. If you have a bench or table top mini mill, please choose bench mill option.
