X Axis base and table top ::
For anyone who need to know how to drill big hole for mounting step motor , how i do?
Big hole ::
How to drill big hole like picture above, it was easy to drill that hole without sending your part to lathe shop.
1. Drill 38mm with hole saw , deep about 2mm
2. Drill 35mm with step drill , then you will get same as picture abouve
Finish build Z-Axis.
I used cheap power drill that i have , it not accuracy and not precision but i can make it more precision and accuracy by process of drilling but some hole will have +- 0.2-0.5mm and how to make it still fit when mounting that was simple. OK how? if need to drill 3mm hole then just drill 3.3mm or 3.5mm hole then 0.3-0.5mm of hole will use for adjust aluminum plate when mounthing.
Just got Water cooled spindle + Inverter + Spindle clamp. So today i do wiring and add Potentiometer to Inverter and then test them to make sure everything work fine and correct wiring.
Item arrive ::
Start wiring ::
Note :: For single phase power use “R” and “T” but for Three phase power use “R” and “S” , or “S” and “T” , both will work fine.
After finish wiring then test run ::
Note :: Before start run it VFD need to parameter setting.
– PD005 = 400 (Hz)
-PD004 = 400 (hz)
– PD003 = 400 (hz)
– PD008 = 220 (220volt)
– PD072 = 400 (hz)
– PD144 = 3000
This parameter need to set up before start run spindle. Other parameter see document.
After test , It work correctly and everything good so next i need to add potentionmeter to font panel of inverter , it already have socket for putting potentionmeter into it.
Done !!! lol
