3D engraving in aluminium

Informations about the High-Z machines Professionals, model makers and hobbyists have long been waiting for this machine. Together with our development department and engineers from the machine construction and electronic sector, we have developed a machine, which is setting new standards with regard to dimension, cost/perfomance ratio and stiffness as well as stability by its new geometry. Besides, it excels by its variety of applicability, which is due to its new frame construction.  Because the frame  is of aluminium, it is also possible to work with an atomized spray plant, which is not possible – of course – with an understructure of particle boards! Additionally, this way you can work at bigger working pieces in stronger bench vices. The complete construction is all in all by approx. 50% lighter. Place the Machine firmly on a 4x5 meter PU-Plate and mill individual letters out........no problem. No specific CNC programming-knowledge is necessary for the operation!  You simply create drawings, model sketches or texts in a drawing programme, e.g. Corel Draw, CAD programmes etc.. These may easily be sent to the milling machine as HPGL-file from the delivered CNC-Software PCNC. Many settings can be made in the   software  e.g. Verfahrgeschwindigkeiten, Scaling, series of milling, immersion depth of the individual tools  etc. The operation is so very easy, once you have become acquainted with the software! Also 3D – Milling is possible with this machine. Three-dimensional objects can e.g. be created in a 3D-CAD system in STL-format and subsequently the file is imported into the software DeskProto, tools parameter, infeed, strategy, accuracy etc. determined and finally put out as CNC-programme, which can be worked off with PC-NC or WinPC-NC. For example, the milling unit is by far superior to the competing products with regards to the stiffness, manufacture and therefore long-term precision of many much more expensive machines  We focus specially on the storing of the threaded spindles. Those are in X and Y at both sides in grooves and thrust ball bearing  so that no power is transferred to the engine camp, which is rather unusual in this price segment. Worth knowing to "increment" and "dissolution" as well as Do-it-yourself machines ! What do I intend to do with the machine ? What price am I prepared to pay for it ? Which materials shall be worked at ? What expectations do I have concerning the accuracy ? It is not easy to judge the indications regarding accuracy: Some manufacturers praise themselves with indications like e.g. increment 0,001875mm ( This figure can also be achieved with our machine in connection with the 4-channel 2.1A 1/8 Micro Servo-Control ( includet in this offer )). This way they try to make their customers think how extremely precise their machine is. Actually, a machine can always work only as precise as the drive screw is. The trapezium spindle used by us has an accuracy of 0,2mm on 300mm, i.e. approx. 0,06mm on 100mm ( 10mm on 0,006mm ). With this accuracy you may even realise belabouring working pieces of aluminium or messing. You need it more accurate only in very seldom cases. Further more, you can read very often in the technical press that in very expensive machines, expensive linear bearings are implemented for the slides. What are the ball-rotating stored linear slides, when the drive screw is a normal trapezium spindle, which is not guided in a ball circulating nut ? It is much easier for the manufacturer of the machine to hide quality deficits in the parallelism of the guide ways, as the ball-rotating stored guide ways run correctly and smoothly even at a deviation of 0,1mm from parallelism. The existing traverse clearance in a buttress thread nut to a spindle is with our machines less than 3 hundreth mm. This can be adapted in the software in programme PCNC up to zero. The traverse clearance makes out only a few steps of the motors. Some closing words to Do-It-Yourself Machines: Keep your hands off quotations for only little used machines from private persons without any legal basis and without any warranty !! These machines do not have a CE-Approval and are consequently neither allowed to be operated nor to be sold. Observing the market here in E-Bay over a certain period of time, one can recognise that permenently Do-It-Yourself machines are put into circulation. Partly, within 2 months, the same machines are being offered by up to 3 different sellers. Probably they think: In case it is no good, sell it again in E-Bay! Somebody will buy the rubbish for a great deal of money. Machines sold within the EU have to undergo an EC-Approval including a danger analysis and an EMV Prüfung etc. Only very few private sellers are able to fulfil these security criteria, as these approvals alone cost approx. 10000 Euro. Being precise, such machines are forbidden to trade with or to operate in Germany. At the latest when during operation the machine catches fire due to a short circuit or somebody gets injured at dealing with the machine it will become obvious that nobody can benefit from this. When the operator has observed the operating instructions, the manufacturer will be blamed for the damage caused. We hope having provided you an insight into the theme and wish you to have fun further on, here in E-Bay. In case you should have any further questions, please do not hesitate to send us an e-mail. Greetings from M.Heinricks of the HEIZ CNC-Team A further "Plus" is the frame construction, which allows it to set up our machine with the help of our Z-Kits higher from the ground, so that e.g. working pieces can be clamped in strong bench vices and belabour them. An alternative can be to place the complete machine onto a big housing in the dimension of e.g. 1x2x3 meter and mill a breakthrough etc. All this is no problem with the High-Z.  We no not have the aim to design a machine with utopian express speeds, but to focus specially on  criteria which is important for the customer like reliability, high quality components as well as stability and cost/performance ratio. With a working area of x-400, y-300, ( at this construction, therefrom results an actual working area of 400 x 300 mm ! ),  z-110 mm and a passage height of 100 mm as well as a repeat accuracy of 0,01-0,03 mm and a maximum positioning speed and a working spped of 3000 mm/min. it is for almost all milling and engraving works in plastics, wood as well as easier chipping in aluminium or messing etc. particularly suitable. Of course, this CNC- machine may also be used for blank drilling, insulation milling or even for cutting of plastic films . Another possibility: use the machine for plasma-burn and build a holder for a mobile plasma-burner.   The tool necessary for cutting plastic films ( Knife Holder, normal sales price 149 Euro ) are given additionally with this bid free of charge! The machine slides are guided in all 3 axes on highly precision 62 Rockwell hardened and grinded  linear guide ways with a diameter of 22mm  ( Z-Axis: 16mm ). This leads to a very high twisting rigidity and allows even milling works in massive aluminium  Please also watch our videos hereto. The threaded spindles are of course running in ball bearings on both sides, so that no power can affect the motor mountings and supports. In 99,9% milling works up to a material depth of 5mm maximum thickness can be executed. Only seldom 80, 90 or 100mm thick working pieces have to be belaboured. Most machines of our competitors use a construction, with an Y-Axis center is  of approx. 300mm minimum height above the machine base.  Of course, such constructions   bring about high leverages and breakdown torque during belabouring of thin material. This has not only an impact on the accuracy of the working pieces, but also on the long life cycle of the machine , if not parts of high quality are implemented in the machine. The sketch shows the red force distribution line of a machine construction which some competitors make use of.          Construction of most machines As to clamping of working piece materials: For clamping of flat or even complex working pieces, you may fix an MDF-Board easily to the base plate, to mill it one time smoothly and affix them easily with e.g. thread inserts for wood and with the help of mounting links. For flat materials or for engraving, you only fasten a further, but plastics coated board on the MDF-Board. It is very easy to fasten safely flat and thin material with double-sided adhesive tape. A downholder for engraving works will additionally be delivered free of charge, providing that the thin engraving material always is laying flatly on the base, so that different engraving depths can be avoided.         Base construction of the High-Z   In   the sketch you may recognise with the force distribution line how warp resistant our machines are constructed.
