| .(1).
Technical specification |
| |
This machine tool is the key manufacturing
installation for graphite electrode. We research
and develop the high-efficiency special NC system
& software by ourselves as the control part
of the equipment. Japanese AC actuating motor
drives the machine tool and the key elements
are products of famous manufacturer. Combined
with the unique mechanical structure, it works
with NC single-end carding machining of electrode
inner cone

thread,
and has functions as follows: Float positioning
of length, auto or manual sharpening of the end
surface, pneumatic clamping of workpiece and auto
centering of support, etc.
With advanced functions, simple & reasonable
structure, convenient operation & adjustment,
adding its high automaticity and low cost, the
machine tool has reached the international advanced
stage in technology and processing accuracy..
