Why use tungsten steel screw cutter
Because of the unique nature of tungsten steel cutting tools. Tungsten steel screw tool trimming quality is the best of all available design tools, in addition, tungsten steel shavings in a variety of shavings machine under the highest speed feed rate can produce excellent trimming effect.
Straight knife
For the straight edge without screw blade design, because the cutting edge and the workpiece when the contact surface is large, there will be a greater friction resistance and make the blade easy to wear. Its service life relative to the screw knife is shorter, suitable for cutting soft material.
Spiral knife
The design of the helical blade can reduce the resistance to contact with the workpiece when cutting, in addition to high-speed cutting can be done, but also improve the processing efficiency. Relative to the straight knife, its longer life than the straight knife, suitable for cutting hard material.
On the knife
The so-called "rotary knife" refers to the "right" spin cutting combined with the "right" spiral groove. The cutter will cause the sawdust to be spirally discharged at the time of cutting, which is particularly useful in the case of milling or non-chip removal. In some cases, cutting the workpiece will be pulled on the situation. An additional fixture may be required or the depth of cut may be done in stages.
When the cutter is used for the cutting of the cutting, the cutting effect at the bottom of the workpiece is fine and smooth. And in the cutting of certain specific materials, it is easy in the top of the processing of rough edges.
On the knife can do a direct vertical down the infeed or drilling action, but the vertical feed prone to chipping the phenomenon, less recommended. We recommend mining slash trajectory feed, slash trajectory feed mode is to gradually increase the axial depth of cut to the set of axial depth of cut, the milling force is gradually increased, so the impact ratio of the tool and the spindle Vertical knife is small, can significantly reduce the phenomenon of knife down the knife.
Under the knife
"Lower Knife" refers to the "right" spin cutting combined with the "left" spiral groove, which is the wood from the bottom of the processing material. The lower cutting method can be used to assist in cutting the workpiece at the same time. The cutting results are opposite to the upper blade, the top is fine and smooth, and the bottom has a rough hairy edge.
Falling chips can sometimes cause problems with clogging, especially in the case of concealed milling troughs.
The use of the lower blade in the use of the prior to the completion of the processing of cutting, this can greatly enhance the lower knife when the trimming processing stability. The lower cutter is less suitable for vertical downward feed, this is easy to cause broken knife or chip problems.
Complex knives
The compound-type screwdriver is a combination of the upper cutter blade and the lower cutter blade on the same tool. The upper and lower edges simultaneously cut the compressible workpieces to avoid the occurrence of debris or burrs at the top or bottom of the work.
The complex-type helical tool is widely used in cutting double-sided laminated laminates, but can also be used on natural wood which will have burr problems.
End milling
The blade for the smooth design, cutting results for the smooth, can be applied to a variety of requirements of the surface of the degree of processing.
Rough milling
Its blade for the waveform design, processing will produce fine lines, cutting results than the end of the cutter rough, and more for the processing does not emphasize the degree of detail, there will be 2 times the processing of the action. Rough milling is not suitable for low feed rates.
Rough milling
The blade is a jagged design, intended to cut the wood generated when cutting, cut into smaller pieces, which can reduce the energy consumption of cutting and tool swing, while more conducive to the removal of wood chips. In the tool without offset swing state, can be completed once the rough milling and detailed processing action. It is generally recommended to use this tool at high feed rates when cutting hardwood or high density materials. Is between the end mill
And rough cutter between the good compromise tools.
Fineness: end milling> rough milling> rough milling
Chip breaking effect: rough milling> rough milling> end milling
Mountain type drilling tail / V drilling tail
Mountain drilling tail: for non-penetrating drilling
V-type drilling tail: for penetrating drilling
The above provides some basic information as a reference for selecting tool and tool applications.
