Frame Built and Painted now Electrics time !!! - Cha-Am Thailand
Hello all
My name is Stein-Erik and I’m from Norway but live now in Thailand Have read in this forum for over a year now but still not sure on everything involved to finish the maschine,hope i can ask if i get in trouble Started my first cnc machine last year and now I’m starting on the MM Table: 3000x2000 mm 4 motor: OM PK 299-F4.5A Unipoler? Spindle: china 2,2kw with HY 02D223B VFD waiting for the laser part made in Thailand, this have been my biggest problem to find a company for making the laser part but now i found it. The steel was also difficult to find the right dimension so for x beam i have 200x80x8cm for the table i have 78x40x5 and the y car 98x48x2.2cm have the most of cables and electric but cannot find a toroid transformer so i have to find a regular on but not sure what type, so far i have cut the most of the steel and working on howe to build the control box ,have no date for finishing the machine but will work on it as a daily basic if I’m not on a motorbike trip or cooling down at the pool or have trips around Thailand. For over a year now i have been to china Town in Bankok looking for parts in the town that never sleep and that is fun and luckily i have manage to find the most of the part for the machine and cheap too. Oops tried to upload some picks but i cant find ut hove |

Welcome to the club.
You can use E-I core tranny, or any type of core for the matter. just stick to the same specification. I'm sure you can get them custom wound in Bangkok too. |

Thanks for that yes iv seen in bankok but at that time i look for toroid tr, is the spec the same as 25x25v?

I think so, Voltage depends on motor phase inductance & your motor driver max voltage capacity. I'm not familiar with OM motor, I'm using 86HS9801 chinese motor w/o the gear head.
The are more then enough info here, use the search button & keep reading. |

i talk to the company that sells rack and piniong and they sad that a 24 teeht gear have a pitch diam. of 24mm and the rach teeth to teeth is 3mm on ther modul 1 is this rigth?

|

Module 1 means 3.14mm between middle of teeth slope so its simply teeth distance. and yes its ok

Thank you for quick reply Danilo
Then i can order my racks and piniongs today, i go for one set of 24 teeth and one set of 30 teeth i plan to build a gearbox 3.3:1 and have a 60 teeth gear and a 18 gear teeth give me a holding torque of 2046 if my calc are rigth and wierd my motors half coil unipoler with a transformer 35VAC,800VA if this is to mutch i hope somone can correct me |

35VAC will give you after capacitor and rectifier an 49.5V DC if my calculation is correct,
OM PK 299-F4.5A have 2.5mH inductance and if you calculate 32*sqrt(2.5) its 50Volts maximum, I would run them a little lower if possible. Someone using PK 299-F4.5A would give a better opinion, or just search the forum there are plenty of posts about power supply |

|

ok so if i go for antec 220v,, 25+25v it will give me 39V rectified

i try to figure out what bob i need some say the the PMDX-122 is the safest and i look at the PMDX-125 with Geko drive 203V becaus i want to have 4 axes at the end of building my machine any coments on that?

now i have order the bob and drivers from Steve
also order the rack and piniongs for my machine i need 9mbut the company says that they only have 4pcs of 2000x15x15mm but they have plenty of 1000x12x12mm so i order what they have on 15x15mm and one met of 12x12mm for the z slide or i have to wait for 6mnds. hope that i can use the 12x12mm and to day i found my toroidal transformer and they promis i have it in one week and it is 10 mm shorter than the spec on AN-8225 The cabelchain i order take abouth 4 weeks to arrived and the brand name is KODUCT 40x25mm inside |

Something looks wrong with the water connections to that spindle - like someone cut them off. Is it obvious to you how to connect hoses to the spindle?

I assumed he photo'd and worded it like that because of the bad fittings there. I hate when expensive things come obviously defective. Maybe an easy out and some new fittings will take care of it quickly.

Selbuss, is that how you planned to cut all your steel? You must be a real tough guy! With the nerve of steel & armored skin! Those Muitai practice sessions sure pays off!

Nice wheels, does Thailand charge tax based on the size of the size of the engine? In Taiwan, we would have to pay a king's ransom annually to keep plates on a beauty like that. Looks like you are off to a good start. Good luck with you build!
