D. NC joint processing machine tool

......1. CGK-21 Joint Double-thread Carding Machine Tool
 
(Patent No. ZL 99 2 29426.6)
 
(1). General
 
This machine tool is key device to process graphite electrode joint, as well as key equipment of automatic NC joint machining line. It controls itself by using high-efficient four-ax NC system and software made by us. With unique open mechanical structure and axial positioning of workpiece, the join double external taper thread chasing cutters can work at the same step.

With advanced function and good structure, precise positioning, this machine tool is simple to operate & debug, and its technology, precision and efficiency reach international advanced level.

It is confirmed to be '2001 High-tech Product of Jiangsu Province by authorities.'

(2). Technical description
 
  • Overall numeric controlled by software, this machine tool eliminates the error caused by mechanical driving chain Pitch of screws and taper precision is good. Numeric control feed in X-direction can make fine adjustment on diameter size and guarantees the size consistency.

  • Two cutters can automatically cut large-scale joints so that quality is assured.
(3). Main technical parameters
 
  • Join diameter:120 ~ 408 mm

  • Join length: 160~584 mm (Corresponding electrode dia.200~750 mm)

  • Single pitch error: 0.015 mm

  • Accumulated pitch error: 0.03 mm / 152.4 mm

  • Thread taper error: 9o 27' 44.5" 0.5'

  • Thread form half angle error: 30o10'

  • Axiality of double-end thread: < = 0.04 mm

  • Thread diameter error: - 0.05~0 mm

  • Pulse equivalent of Z direction: 0.001 mm / pulse

  • Pulse equivalent of X direction: 0.0005mm / pulse

  • Net time for each workpiece: < = 2 min/ pc
