Vh
– precision boring heads are used for precision boring of cylindrical holes in the given range of
diameters. The range is Ø6-225 mm and with special tools can be up to 400 mm. These heads
can be used for boring and milling machines, NC-machine tools, etc. Taper shank type VK360
(for Vh70) and taper shank VK801 (for Vh 110, Vh 140) are exchangeable – taper shank
isn't part
of the head's body, it must be ordered separately.
These heads are composed of a body (1) and of an exchangeable taper shank
type VK360 and VK801 which is attached to the head by four screws (11). In the body is slide (2).
Slide movement depends on operating screw (3). When there is started bolt (10) is accuracy of
adjustment lower – by turning operating screw for 1 division is slide shifted for 0,01 mm (boring
diameter is bigger for 0,02 mm). By tightening of the operating screw is accuracy of adjustment
in function where 1 division = 0,0025mm/Ø (slide is shifted for 0,00125mm).
For enlargement of boring possibilities can be delivered set of boring tools
VDSK 16 (for Vh70), VDSK 25 (Vh 110 and Vh140).

Frequently asked questions (FAQ)
|
|
|
|
Mainly with an accuracy of IT7 and higher, only boring head 205 with an accuracy of IT6
up to IT5. |
|
|
Minimum
diameter of boring slot is around 6mm. For smaller
diameters firm NAREX MTE does not deliver tools. We
can say that the minimum diameter depends on tool
not on the head. Head is restricted by revolutions
and this way is restricted cutting speed on the
tool. |
|
|
All except universal boring heads Vhu which need direct staff.
There are operation during buttoned shog on Vhu. All other operations - boring can be realized on NC
and CNC machines. |
|
|
1.500 RPM by Vh 70, 800 RPM by Vh 110, 500 RPM by Vh 140. |
|
|
Boring head is designed only for boring of cylindrical slots.
Universal boring head is for operations which need cross tool movement during head turning.
This makes possible spotface slots faces and bore taper slots. |
|
|
Usually
to the deepness according to heads accessories.
There are bars, holders and boring tools. Their
length you find in relevant catalogue or
here (Basic operations with boring head
Vh). |
|
|
Boring head needs spindle machine rigidity, table rigidity and
clamping of the part. Furthermore needs machine feed with possibility of its switch-off in needed place.
If the rigidity is insufficient the boring result is not reliable. |

Taper shanks VK360 have flange diameter 70mm.
Shanks VK801 have flange diameter 110mm. VK360 are designed for Vhu 36, Vh 70, Vhs 50,
and Vhs 10-125. Taper shanks VK801 are designed for boring heads Vhu 56 to Vhu 160, Vh 110,
Vh 140 and Vhs 40-180. There is also type VK800 R8 but it is designed only for head Vhu 56 and
especially for North American market. |
