Comparative CNC Test
Test of a copied High-Z CNC machine built by a competitor
We felt induced to do this test because of the following story:
2004 we found out there’s no supplier on the market of CNC portal milling machines with a proper cost/ performance ratio and so we decided to change this fact and apparently we get it done.
After a development phase of 10 months we introduced our High-Z on the market on January 2005. Since 12.01.2005 till today ( 1.9.2007 ) we have sold over 900 High-Z CNC milling machines worldwide.
We owe a big part of this success to our management floor which always makes an effort to adapt electronic and mechanical parts of High-Z series and to optimize them long- term in order to ensure further high level quality and low prices.
Unfortunately our High-Z series is badly copied by some competitors and sold for similar prices. This fact induced us to buy one of this machines and to test it.
The alarming result is reported on this page.
Self aware we covered up some components of the machine or show just small exerpts in order not to supply our competitors a disadvantage on market. In the meantime there are 5 different suppliers in internet who offer a copy of our machine.
|All following results were achieved with 6 witnesses and are in accordance with truth.|
One more “jalopy“
The final video of a further construction’s imitator of our machine. The video presents a self- production of this company. We paid attention because 3 persons interested in our High-Z mourned the precision of this machine by one special company. One customer even offered his own mangle afflicted machine for presentation. At this opportunity we took this video. This competitor promises a precision of 0,02-0,03mm while milling in brass or aluminium because of machine’s stability! VIDEO. We can’t prove this ability. We traded the machine which is now part of our CNC-STEP company.
We were shocked how boldly traders deceive their customers. We don’t know how they want to achieve on axle precision better than 0,2mm on effective diameter with a convential DIN 103 screw nut, a not specially adapted TR16 red brass or brass nut ( 7H ) because the tolerance values for rolled spindles ( 7e ) and turned nuts are determined ( in DIN 103 ) ! This is an information paper about tolerances.
Let’s not speak about electronic parts’ quality…
Buying a CNC milling machine you can trust a smiling trader who says : “20 years experience in machine making” , or your own intuition. The most useful way to a tailor-made and high quality product is in our opinion the own convincing and trader’s possessed references.
We trust on individually adapted components. We order undersized nylatron nuts and adapt them individually to the spindles. Same way we fit every single box to the used linear guide ways. This needs tie and of course a certain investment in the product !!
After consulting us you are welcome for a presentation of our machine production. On your wish we would put a measuring instrument on a finished machine to prove the precision. Or you can send us a data file and the material you want to work on. We would create a video for you about working and feasibility with our machines.
Our name will further stand for high quality.
