direction.  If  the  red  mark  in  the  turn-over  button  (21)  points  upward,  the  micro-active 
hand-wheel may turn. The micro-active hand-wheel has a large transmitting ratio to make 
the  spindle  move  extremely  slowly.  The  circumferential  motion  of  the  handwheel  is 
converted into the axial motion of the spindle through the friction device. This system is 
used  to  measure  a  hole  during  using  the  electrical  measuring  accessories.  During  using 
the system, the inner/outer tension force dragline shall be relieved, so is the locking screw 
of the measuring spindle. 
 
4.3 Tailstock (See Fig.2)   
The spindle of the tailstock is used to fix the datum (location plane). Its sliding carrier (31) 
may  move  on  the  base  right  track  and  to  be  locked  at  any  position  with  the 
handwheel(16).  The  measuring  rod,  which  is  equipped  with  cap-shaped  measuring 
accessories,  can  be  adjusted  by  screws  (28  and  29)  to  make  the  spherical  measuring 
accessories  concentric  or  the  plain  cap-shaped  measuring  accessories  parallel  with  each 
other. 
 
4.4 Electrical measuring accessories (See Fig.4, 5 and 12) 
It  includes  an  insulting  worktable  (Fig.5)  with  an  infrared  light  emitting  diode

 

(34),  the 

measuring accessories (Fig.4), and a measuring rod with a ball at its end. This device is 

mainly  used  to  measure  a  hole  with  a  diameter  within(1

60)mm.  It  can  be  used  to 

measure  a  hole  with  a  diameter  within

The  surface  (35)  of  insulting  worktable  (Fig.5)  is  separated  by  insulting  block  (36)  to 
make  it  insulate  with  the  worktable  base  (37).there  is  a  notch  in  the  surface  to  let  the  a 
measuring ball end rod insert into the hole to be measured. The workpiece is put on the 
insulting  worktable.  Small  size  parts  can  be  placed  on  the  insulting  worktable  with  a 
central ring (38 crossing through the hole. 
 

The  insulating  worktable  is  mounted  on  the  universal  worktable  and  fixed  in  the 

wedge  slot  with  screws  (39  and  40).  The  long  level  meter  on  the  insulating  worktable 
base(37),  is  used  to  adjust  accurately  the  worktable  level.  The  insulating  worktable  is 
powered by a 6V transformer. The press plate, fixed on the workpiece to be measured, is 
put  into  the  slot(41).  When  the  probe  contacts  with  the  workpiece,  the  infrared  light 
emitting diode will light. The measuring accessories are mounted on the spindle (Fig.12) 
and  locked  with  a  button  (43).  ball  end  rod  is  fixed  in  the  hole  (44)  of  the  measuring 
accessories  and  locked  with  screw  (45).  Both  ball  end  rod  (46  or  47)  and  the  electrical 
measuring accessories are used to measure a hole. The scale on the measuring rod shows
