(1) the A of 　 of the 　 that connect a line, wire that must use the provision in this manual or function more the lead of actor. B, forbidden be together this machine tool power source and join of tall electromagnetism equipment. Be like: High frequency quench machine, arc welding. The C, eligible electric professional that should have experience by arrangement is in charge of wiring. (2) the ground wire that ground connection should use 14mm2 of cross section ＞ . Wire gauge case should be more than AWG (American line standard) 　 　 NO.

5 or SWG (British line standard) NO.

6. Machine tool of ordinary numerical control should join with separate ground connection staff, if do not have a condition to be able to press the following preparation: A, get on one alone conductor join to earthing terminal, can avoid the trouble that ground connection electric current causes so. B, when if use rod of concrete reinforcing steel bar,be being nodded as ground connection, notice all the more please, undertake by the following requirement when join: Ⅰ , do not use rod of collective ground connection reinforcing steel bar with other equipment, the wiring terminal of earthing terminal or other equipment, be like electric welder, high frequency quench machine. The Ⅱ , wiring terminal that should make appliance has enough and electric property. The C, ground wire that should use depart, length should as far as possible short. Measure resistance of examination ground connection D, actually, be like only when a machine tool and ground connection lever are linked together, resistor should be less than 100 Ω . The requirement should become independent ground connection CNC Milling CNC Machining
