1. Basic data: 1 machine spindle speed, 2
workpiece thickness and material, 3 blade saw outer diameter and aperture
(shaft diameter);
2. Selection basis: Calculated by the
spindle rotation number and the outer diameter of the mating saw blade. Cutting
speed: V=π×outer diameter D×number of revolutions N/60 (m/s) The reasonable
cutting speed is generally 60-90 m/ second,
Specific recommendations(for example):
Material cutting speed
Cork 60-90 (m / s)
Hardwood 50-70 (m / s)
Particleboard, plywood 60-80 (m / s)
The cutting speed is too large, the machine
tool has large vibration, large noise, reduced saw blade stability, reduced
processing quality, too small cutting speed, and reduced production efficiency.
The same feed speed, the amount of cutting per tooth increases, affecting the
quality of the machining and the life of the saw. Because the saw blade
diameter D and the spindle rotational speed N are power functions, in practical
applications, it is most economical to increase the rotational speed reasonably
and reduce the saw blade diameter.
3,The price ratio:
As the saying goes: "It's not cheap,
good goods are not cheap." It may be true for other goods, but it may not
be true for tool tools; the key is matching. Many factors on the job site: such
as equipment sawing objects, quality requirements, personnel quality, etc.
Conduct comprehensive assessments, rationally choose the best use of materials,
just right, to save money, reduce costs, and participate in industry
competition. This depends on mastery of professional knowledge and
understanding of similar product information.
Second, the correct use:
In order to make the saw blade perform its
best performance, it must be used in strict accordance with the specifications;
1. Saw blades of different specifications
and uses have different cutter head angles and base forms, so try to use them
according to their corresponding occasions;
2. The size and shape accuracy of the
spindle and the clamp of the equipment have a great influence on the use
effect. Check and adjust before installing the saw blade. In particular, the
factors affecting the displacement and slippage caused by the contact surface
between the splint and the saw blade must be eliminated;
3. Pay attention to the working condition
of the saw blade at any time, abnormalities, such as vibration, humming, and
the surface of the processing surface, must be stopped and adjusted in time,
and repaired in time to maintain the peak profit;
4. Repair the saw blade must not change its
original angle, to avoid partial hot flashing of the cutter head, it is best to
professionally repair the grinding
5. The saw blades that are not used for a
long time should be hung vertically, avoiding the flat lay for a long time, and
should not be placed on the object stack. The cutter head should be protected
from collision.
