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

accessories are applied.

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
