A kind of timber grinding and polishing method
Technical field
The invention belongs to timber grinding and polishing technical fields, and in particular to a kind of timber grinding and polishing method.
Background technology
In timber process, the wood surface by preliminary working can remain the flaws such as jagged, overlap, it is necessary to wood
Material surface is polished and is polished, and timber grinding and polishing equipment is exactly to be used for carrying out polishing to wood surface with polishing.Grinding and polishing is set
Standby to be above provided with grinding and polishing main shaft, the main the tip of the axis of grinding and polishing is provided with emery wheel or polishing wheel, and the material used in grinding wheel surface is mainly
Nylon or wire, and be all vertical, existing timber grinding and polishing equipment has for the plane grinding and polishing of some tablet timber
Preferable grinding and polishing effect, but it is unsatisfactory for the grinding and polishing effect of convex-concave surface of some board surfaces with decorative pattern.
Grinding and polishing for this kind of convex-concave surface, during grinding and polishing, the grinding material of grinding wheel surface is due to always in compression
Deformation state is not easy to touch concave bottom, and the chip under grinding can be remained in concave surface, be not easy to discharge, this is resulted in
The grinding material of emery wheel can not more act on concave surface.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of timber grinding and polishing method, this method can be big
The big grinding and polishing effect promoted to timber convex-concave surface.
The present invention is achieved by the following technical solutions:
A kind of timber grinding and polishing method:During grinding and polishing, workpiece is generated laterally with emery wheel (i.e. parallel to workpiece surface side
To) relative motion while, make to generate longitudinal clutch campaign (i.e. perpendicular to workpiece surface direction) between emery wheel and workpiece, pass through
Longitudinal clutch campaign enables in the recessed joint of the grinding deep enough workpiece of silk of emery wheel, and the sawdust in recessed joint is taken out of, so as to be promoted
To the grinding and polishing effect of recessed joint.
In the above-mentioned technical solutions, the grinding silk of grinding wheel surface is along emery wheel radial distribution, during grinding and polishing, when emery wheel and work
After part separation certain interval, the grinding silk of emery wheel becomes erectility again, so when emery wheel presses workpiece again, emery wheel
In the recessed joint of the deep enough workpiece of grinding silk energy of erectility.
In the above-mentioned technical solutions, timber grinding and polishing method uses a kind of new emery wheel, and emery wheel includes emery wheel core and mill
Silk is thrown, the grinding and polishing silk is arranged on along emery wheel is radially upstanding on emery wheel core;The grinding and polishing silk is helical structure, and grinding and polishing silk is preferred
For nylon yarn, surface has larger roughness, and the grinding and polishing silk of helical structure is compared to traditional linear pattern grinding and polishing material, Neng Gouzeng
The contact area of big grinding and polishing silk and work piece, and helical structure can promote to take sawdust out of concave surface, so as to promote grinding and polishing
Effect.
In the above-mentioned technical solutions, timber grinding and polishing method use a kind of new emery wheel, the emery wheel include emery wheel core with
And grinding and polishing material, for emery wheel core for grinding and polishing material to be driven to roll, grinding and polishing material is used to remove the burr and overlap of wood surface;
The emery wheel core is cylindrical metal core, and the through hole of left and right ends is provided through in emery wheel core.
Further, the both ends of the surface of emery wheel core are provided with multiple screw holes, convenient for the installation and replacement of emery wheel.
Further, the madial wall of the fixed hole is provided with keyway, the keyway and main shaft on fixed hole on emery wheel
The axle center of end be mutually buckled, the combination for making emery wheel and main shaft is more secured.
Further, the grinding and polishing material includes the first grinding and polishing material and the second grinding and polishing material;The first grinding and polishing material
For planar, the first grinding and polishing material is covered in the side of emery wheel core;The second grinding and polishing material banding, the second grinding and polishing material is from mill
One end of core is taken turns to the other end, spiral wrap is in the surface of the first friction material.When emery wheel works, the first grinding and polishing material fills
Point with workpiece table plane contact, to workpiece table plane carry out grinding and polishing.For bump existing for workpiece surface, the second grinding and polishing material
In banded structure can effectively to bump carry out grinding and polishing, so as to improve grinding and polishing quality, avoid excessive to workpiece surface
Abrasion.
Further, the first grinding and polishing material is nylon or wire.
Further, the second grinding and polishing material is woollen, and the first grinding and polishing material and the second grinding and polishing material are not restricted to above-mentioned
The material, such as soft material cotton material, fiber.
The advantages of the present invention are:
The timber grinding and polishing method of the present invention generates laterally (i.e. parallel to workpiece surface direction) grinding and polishing in workpiece and emery wheel and transports
While dynamic, extensional vibration is generated using oscillation drive driving workpiece so that generated between emery wheel and workpiece longitudinal direction from
Resultant motion (i.e. perpendicular to workpiece surface direction) enables the recessed joint of the grinding deep enough workpiece of silk of emery wheel by longitudinal clutch campaign
In (the grinding silk used in grinding wheel surface is mainly nylon or wire, and these grinding silks are radially set along emery wheel, work as emery wheel
After separating certain interval with workpiece, the grinding silk of emery wheel becomes erectility again, so when emery wheel presses workpiece again, mill
In the recessed joint of the deep enough workpiece of grinding silk energy of the erectility of wheel), and the sawdust in recessed joint is taken out of, so as to be promoted to recessed joint
Grinding and polishing effect.
In addition, timber grinding and polishing method uses a kind of new emery wheel, emery wheel includes emery wheel core and grinding and polishing silk, the grinding and polishing
Silk is arranged on along emery wheel is radially upstanding on emery wheel core;The grinding and polishing silk is helical structure, and grinding and polishing silk is preferably nylon yarn, surface
With larger roughness, the grinding and polishing silk of helical structure can increase grinding and polishing silk and quilt compared to traditional linear pattern grinding and polishing material
The contact area of workpiece, and helical structure can promote to take sawdust out of concave surface, so as to promote grinding and polishing effect.
