BT-150HS PCD end mill tool grinding machine is economically
manufactured
and grinding PCD, PCBN and CVD tools; manufacture and grinding
carbide
and high speed steel non-standard blades.When grinding standard or
non-standard welding inserts, clip blades, boring inserts, grooving
insert, and
other types of tools, it is easy to grind angle and arc transition
blades on these
tools.I. Machine tool characteristics of PCD end mill tool grinding
machine:Our Advantages
1. Mechanical structure of the machine tool: the machine tool bed
body (base)
adopts high-quality integral casting, and the main components
weight of 1.6
tons, which can meet the requirements of any super hard material
grinding.
2. Electric spindle of machine: grinding head adopts high-precision
frequency
conversion and speed regulating electric spindle, adopts
circulating water
cooling, grinding head spindle rotation accuracy: end jump: 0.002
mm; radial
beat: 0.003 mm.
3. Pneumatic feed mechanism: the machine tool adopts the "constant
pressure
grinding" technology, that is, in the tool grinding process, the
tool always bears
a constant air pressure, so that the grinding process is balanced
and stable,
and the overall grinding efficiency is high.
4. Auxiliary work: the tool approaches the grinding wheel, and the
tool returns
to the loading position after grinding. These two actions are fast
forward and
fast retreat through the pneumatic feed device, which can save the
auxiliary
time up to 70%.
5. Grinding head reciprocating servo swing: the servo motor
realizes the
reciprocating swing of the grinding wheel, and the range is
randomly adjusted
between 0 and 30 mm, so that the grinding wheel is evenly consumed,
timely
self-sharp, to ensure the grinding precision and roughness.
6. Online CCD measurement: using optical microscope and CCD camera
amplification technology, magnification between 25~80, used for
alignment
line is generated by software, after calibration as a benchmark,
ensure the
alignment accuracy, make the machine can accurately detect the
sharp arc,
Angle line and graphics import function, non-standard tool
alignment
measurement.
7. Radial axial locking of grinding wheel: the radial locking
technology of
grinding wheel spindle makes the concave and convex phase of the
two
circular arc guide rail hold the brake tight, achieves the smooth
contact without
gap, and greatly enhances the rigidity of the equipment.The
adjustment of the
grinding wheel elevation (which determines the rear corner of the
tool) does
not change the position of the center line of the grinding wheel,
so the coarse
fine grinding does not need to adjust the grinding wheel height.
8. Grinding head lifting adjustment shaft: the grinding point
vertical lifting
device developed for non-standard tools (such as V-cut tool, dense
tooth
milling tool and tool front blade, etc.), lifting distance of ±
75cm, easy operation.
II.Technological breakthrough points of PCD end mill tool grinding
machine:
1. Optimization of vertical axis: the slightly adjusted vertical
axis lifting is
integrated on the fixture of the workbench, which greatly enhances
the stability
and rigidity of the equipment.
2. More stable feed: PCD is a hard and brittle material that cannot
withstand
the impact force (especially cyclical), so our company's improved
machine tool
has designed a "flexible feed" device with air pressure, making the
tool blade
has the impact, effectively improving the roughness of the blade.
3. Our company uses a large screen to display the tool image,
located directly
in front of the operating station, without having to frequently
turn the head and
head, as long as the "eye lift" can cooperate, improve the
production efficiency
by about 50%.
4. Equipped with grinding head lifting adjustment shaft, the
grinding point
vertical lifting device is developed for non-standard cutting tools
(such as
V-cut tool, dense tooth milling cutter and tool front cutting
surface, etc.), with a
