PCD end mill tool grinding machine
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:
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
lifting distance of ± 75cm.
