MadVac CNC - home made 4'x8' cnc precision gantry router The design objectives for MadVac CNC: General purpose 4 axis (two Z axis) production machine capable of 2D and 3D routing of material within 7" x 52" x 99" envelope Milling wood, plywood, plastics, all grades of aluminum and softer metals 3D mold making Repeatability and precision of movement to 0.0005" and better Heavy, relatively rigid structure Easily accessible open table Small footprint base Modular design for disassembly, moving and reassembly Repeatable and accurate assembly Upgradeable to servo motors Compact Y gantry with Z and W axis both of which can work in 52" x 99" envelope Mobile controller console that can move to any point around the machine Complete mechanical, electronics, software system under $16,000. A few random thoughts and reflections about the project: The research, design and planning of every component, materials and aspect of this machine took about one full year and the construction itself started in Jan 2004 and was 95% finished in July 2004.

A cycloidal drive or cycloidal speed reducer is a mechanism for reducing the speed of an input shaft by a certain ratio. Cycloidal speed reducers are capable of high ratios in compact sizes. [1] Theory of operation[edit] Parts of a 10:1 cycloidal speed reducer mechanism The input shaft is mounted eccentrically to the ball bearing, causing the cycloidal disc to move in a circle.

untitled William L's Scratch Built CNC Machine Here is a scratch built machine (from the plans or book) that exhibits great workmanship, but more importantly, how some of the construction of the CNC machine was done. William L. used sound techniques to make sure the machine would be constructed as intended, knowing that some of the machine would have various size differences within the sub assemblies that would make some of the measurements within the plans not work. It is important to note that the video process for constructing a CNC machine on this site should be watched as a minimum requirement for constructing the CNC machine from the plans or the book. This will provide you with a good understanding of a few techniques to make sure that the measurements for certain parts will work. unnamed pearl

boring head boring head 9. Engraved lines have been filled with a marker pen to improve contrast. Note that the micrometer dial has 25 divisions and the micrometer thread has a 0.5 mm pitch. Thus, a complete turn of the dial moves the boring head 0.5 mm, and adjusting the dial one increment moves the boring head 0.5/25 = 0.02 mm. An Allen head set-screw is fixed in the center of the micrometer head with Loctite, medium strength.
Betrachtungen zur Leistung von Schrittmotoren « SCHRITTMOTOR-BLOG DIPL.-ING. THORSTEN OSTERMANN SCHRITTMOTOR-BLOG DIPL.-ING. THORSTEN OSTERMANN Da mich immer wieder Anfragen zur Auslegung von Netzteilen für Schrittmotor-Steuerungen erreichen, habe ich vor einigen Jahren angefangen, mich etwas intensiver mit dem Thema auseinander zu setzen. Eine Anfrage bei verschiedenen Herstellern von Schrittmotoren, wie denn die Leistungsaufnahme von Schrittmotor und –Endstufe zu berechnen sei, stieß überwiegend auf Achselzucken. Die einzigen Aussagen zum Thema waren, dass so etwas normalerweise nicht berechnet, sondern in der jeweiligen Anwendung gemessen würde. Das mag für Serienanwendungen sicherlich die einfachste Lösung sein. Für den Sondermaschinenbauer, der nur eine Anlage baut, ist diese Herangehensweise aber nicht befriedigend.

Welcher SM ist der richtige für meine Anwendung? Hat ein Motor mit höherer Spannung mehr Kraft? Woher bekomme ich (preiswerte) Schrittmotoren? Warum verliert der SM bei hohen Drehzahlen Schritte? Warum soll ich die SM-Karte mit 24Volt oder mehr betreiben, wenn auf dem Motor 5,1 Volt steht? schritt schritt

CNC Mill Servo Spindle Conversion One of the last major modifications to my mill that I have wanted to make is replacing the 3 phase spindle motor, vfd, and vari-speed drive with a servo motor. Several years ago I had picked up a 3.5kw Mitsubishi MR-J2S series servo motor when one popped up on ebay for a couple hundred bucks. The plan was I would use that motor to replace the 2kw servo motor in the 10EE with this once I found a drive for it and then move the 2kw motor to the mill. Well, in the two years that it took for the correct drive to show up on ebay I got that injection molding press and used the 5kw motor and drive in there to replace the 2kw in the lathe. So that left me with the 3.5kw.Now that I am out of work and have some time on my hands and no projects I need the mill for I figured I would give this project a try.

Photointeruptors come in a lot of different flavors, some costing under US$ 1.00Some have lenses over the LED and some do not. Some have wires attached and some have only bare pins. Some have polycarb housings and some use much cheaper plastic. Success! Mini Machining Center under Mach3 control - Video link
Backlash, a clearance between mating gear teeth, is built into speed reducers to let the gears mesh without binding and to provide space for a film of lubricating oil between the teeth. This prevents overheating and tooth damage. On the other hand, the same clearance causes lost motion between reducer input and output shafts, making it difficult to achieve accurate positioning in equipment such as instruments, machine tools, and robots. For these applications, there are three basic ways to reduce or eliminate backlash: precision gears, modified gears, and special designs that use components other than gears.
