Hello all, first my user name is because my shop is located in Fox Alaska. I have been doing machine work for over 30 years. I have also worked in many associated industrial fields.
My shop is mostly populated with manual machines, we make complete machines, and short-run production parts, generally 6-200 parts per run. My website is ugly, but You can see some of our older machine builds at howeesmachine.com. The last time I programmed a CNC machine was 1979, of course that was punch tape & I remember the concept, but will need to learn the rest again. I have Solidworks, and Turbocad, and also Autocad 2000, but I do not use the Autocad, I mostly use Solidworks.
Summer before last I purchased 2 MH800C, 5 axis mills from York at European Machine Tools. Currently I machine mostly alloy steel 6150, 4140. I envision using one machine to work with the daily customer stuff, and the other for a rifle manufacturing project I have started, so it would make aluminum molds (for wax injection, to produce shell mold castings), and milling on smaller steel & bronze parts.
Both machines had old memory batteries, and hence lost the constants, I have the constants on paper, and CD. I have the factory operation/maintenance, and the electrical. One is a swivel/rotary table with 432-10 control serial #85354, the other is a rotary table with swivel head control is 532-600? or was it 6000? Serial #85700
My initial hold-up in getting the machines running, has been both the "pesky customers" wanting their parts, and also my desire to install the wiring the way I wanted it.
I currently have both machines hard wired to a 380v 150A 3ph transformer & sub panel with spots open for other machines, including an older Agie 200 wire-cut EDM that I bought a few years ago.
The shop is supplied by 2 meters, one 480v 3ph & the other 240 1ph. Shop is 5000 sq. ft. has a 5 ton overhead crane, good lighting, and is way too crowded.
After much searching, I found out about the N80 C not = 0 setting to allow setting other constants, and slowly loaded the constants in the 432 machine. Before loading the constants, the hydraulic pump would come on & not stay latched, after the constants, the hydraulics have latched on for up to 40 seconds twice. Currently the hydraulics will not come on at all, errors sometimes I01, and always I05. I do not know if this is coincidence, but just before the hydraulic quit coming on, I had manually closed the coolant pump contactor to test, and cycled all the breakers (I have seen these same style Siemens breakers cause problems with manual machines many times before). I find the Maho schematics hard to use, I do not have a full grasp of the hydraulic pump contactor coil chain of supply. I will study the diagrams more, but for now, I will start putting the constants into the 532 machine. The 532 is better for a current job as it has the larger table, but I thought the 432, with fewer constants might be easier to get going.
Does a true repair manual exist? Something that lists the full function/range of each of the constants would be nice?
What is the hydraulic pressure supposed to be?
I have purchased many new Cat40 holders, but I need to know what pull studs to buy? Neither machine has any of the blocking pins in the tool chain, nor the spindle.
Thank You, John Howe
