Electric Planer is an indispensable tool for construction and repair of houses, as in any power tool, in his unit are consumables.In electroplane consumables appear knives with which and processed wood.Usually, knives are double-sided, complete with 2 pieces.Remember: if the planer shavings removes bad and you have dull knives, then it is time to change them.But in this case it is necessary to mention that some of them just to be sharpened.For this and need to know how to put electroplane knives after sharpening and how to conduct the procedure itself sharpening knives.

blades mounted on a rotatingelectroplane drum and intended to remove the top layer of the material during the procedure planing of wood products.If the casing is 1 or 2.
Blades come in the form: straight - are used for rebating and planing narrow workpieces;rounded - are intended for the treatment of wide areas because the transitions between the lines planing they do accurately;wavy - shaped knives electroplane suited to simulate "aged" surfaces.
Before using electroplane each time it is recommended to check whether the blades are installed.Their cutting edge should just act out and arranged in parallel with the bottom of the planer.To determine how to handle a knife, lift the instrument at eye level soles upward.
over sole 0.5 mm on average should act knife edge.In sherhebelem it is meant for initial coarse planing, cutting edge should be released no less than 1 millimeter.Adjust the position of the knife is very simple.Turn left and right consistently small and large adjustment screws, which are located behind the platform for electroplane blade until the cutting edge does not take the correct position.
Then set the knife in elektrorubanok and secure position by centering lever and the screw on the top plate.The new power planners usually have adjusted the position of the knife.However, after prolonged use setting will be off.Therefore, if you use the plane after a long break, you need to start to check whether all the case.Do not start treatment once the details have just adjusted an electric planes, without testing it on unnecessary board.
Classification knives electroplane
also knives electroplane separated by size.If you import plane, for example, the company Black & amp; Dekker or Skil, there are the traditional 82 millimeter blades, they are called by the people "plates."From the best value possible to advise knives manufacturer "Zubr" carbon steel.These knives are suitable for the majority of foreign planes, even for professional power tools Bosch and Makita.
Exact dimensions: length 82 mm, width of 5.5 mm and a thickness of 1.2 millimeters.On sale you can find knives of various manufacturers and price in this case depends on the company in the first place.If boshevskie purchase, the cost will be higher than 2 times than that of ordinary household - Bison, Stayer, Fit, Matrix.Of course, as the difference is quite pronounced.
There are knives that are specially designed for certain models of electric planers.For popular and planers Interskol Baikal designed special knives, they are wider than the "plate", and thicker.They are stronger, and when a plane with electric you raid on a twig or nail, the blade will not break and easy to remove notch on sandpaper.
width of these blades is always about 1 centimeter, they differ significantly from the others.These knives are electroplane different lengths: 82 and 102 millimeters for different models of Baikal and Interskol.If like dull knives, they can always hone their own.In contrast to the thin, they will sharpen sandpaper on at owning the skills and abilities to withstand sharpening plane.
And the third kind of knives for electric planers - wide and thick, with the presence of holes for fastening.These are very specific and are suitable only for certain models, such as planers producer Rebir, which have a capacity of 2000 watts.These knives are characterized by high capacity and thick, the width of up to 110 millimeters.

the knives electroplane imposed the highest demands.What they are dull, you can easily determine at a glance.Look for it in the light of the chamfer glands and turn around the cutting edge.The cutting edge blunted if at the end of the chamfer appears in the form of a strip of shiny thread in a position.The angle of the knife sharpening electroplane should be close to 30 degrees.
Today, there are knives for electroplane using a rotary cutter.If one of these blades blunted knife, a knife made on the first turn, and the next time - replacing a new sharp knife.
knives electroplane set in cutter bar, which is located in the conical transverse groove and clamped three nuts.At the height of the blades are regulated by two screws located on the edges.To get the knife from the cutter bar, loosen the screws, tighten the screws until the end of the screws, which will help to push the groove of the cutter bar.
You must then choose a drift that is suitable for the thickness of the blade, and using it to knock the knife in the transverse direction of the cutter bar.Then turn the knife or take a new one, if the former is not suitable, and gently pound it into place, putting the side.Keep the knife in the knife carrier went strictly parallel to it.
put on the new electric planer knives, should put them at the height of the screws and tighten the nuts.This is recommended for both blades exhibit the same clearance, otherwise the shaft imbalance will occur.

When planing to achieve a good surface quality can only be used in the planer sharp knife.If the cutting edge is a little blunt and chipping is not, it will sharpen by the changes.Dull or serrated knives is recommended to grind on the grinding wheel.
When grinding blade on the grinding wheel it freely placed on a flat supporting surface or clamped in the slide.When a piece of metal grinding on the need to move the grinding disc from side to side.Due to the friction with the heating of the parts is accomplished.It is therefore necessary to provide the processing products moderate pressure to the cutting edge does not lose its hardness and zasinela.
electroplane knife after grinding must be subjected to revision.Only through this manipulation he will get the desired sharpness.To manually adjust the blades electroplane use artificial or natural bars, called whetstones.Native image on a piece of iron can straighten lapping disk.
the Belgian touchstone edits can be made only with the addition of water.In the bars of Arkansas for editing on the contrary, a mixture of oil and kerosene.Artificial whetstones are available with varying levels of grinding.Many are fine-grained and coarse side.
-grain side is for pre-editing and fine-grain needed for fine editing.To edit the blades on artificial touchstone can use a mixture of oil or water.On dry bar can not rule in any case, because the blade will lose quenching (release) will be blunt.The bar from time to time need to wash, to hone not salted.
chamfer when dressing well balk at the bar and lead it until crosswise, until it becomes so shiny as a mirror, and all burrs disappear.The front side of the glands on the touchstone drive only up and down, and the procedure it changes over time lasts less.
honing lapping disc made of artificial material, which contains finely divided abrasive agent.With these discs you can edit knives electroplane in engine mode.
Sharpening knives electroplane
Before the procedure, the replacement knives electroplane first need to determine the need for its conduct.Learn it's easy if elektrorubanok worse passes on preparation than ever before, you need to start perezatocheniyu his knives.In addition, remember that Blunt blades can increase the risk of garbage apparatus in contact with rigid portions of wood, for example, knots.
first step in sharpening the knife electroplane is to put an abrasive stone for a few minutes in the water.Stone a must absorb as much moisture.This contributes to the avoidance of excessive dust and improves the quality of sharpening electroplane.It is important to keep track with the sharpening of knives, so that they touch the abrasive stone and at the same angle all the time.
second phase - lock knife in a special block.To sharpen the knife for quality electroplane, made use of a special device that will help prevent violations of geometry or balancing knives.Loosen the two nuts that secure the clamping plate pads, knives and insert fully into the device for sharpening knives electroplane.Then re-tighten the locking nuts.Make sure that the cutting edges of blades arranged in one plane.
third step - directly to the process of sharpening.Sharpening knives electroplane must be done by a special technology.Steel on regrinding knives is so high quality that it allows good resharpen knives and make them as sharp as a razor.However, make sure that the balance is not broken blades.As used in electroplane two knives, it is strictly a matter of balancing.
straight lined blade during sharpening check in using any straight surface.The entire length of the blade width of the chamfer must be exactly the same.Knives are usually sharpened on manual winepress.Sharpen recommended as the time until the blade appear the finest burrs that are difficult to distinguish by eye.Strive to obtain a flat facet, without concave and convex.Burrs must be removed.To do this, a knife sharpening knives electroplane placed flat on the other side of the bar and spend some time on it.
Assembly knives electroplane
After sharpening the knife in the first place, connect it to the plate.Lining the edge he must speak at 3 millimeters.Fully assemble a tool to adjust the correct position of the knife to its edge extends over the edge platform, as expected, at 0.5 millimeters.Knife and trim, connect with one screw.Loosen the screw, turn the knife 90 degrees and details of disconnect.
Please attach a knife to a bar bevel and move it into a position forward and backward at an acute angle of 30 degrees.When any burrs on the cutting edge, turn the knife, put the flat on the bar and move back and forth to remove burrs.The edge of the knife trim the edge should protrude 3 millimeters.The screw that holds the cover plate and the knife must be tightened properly, so that after prolonged use both parts to each other fit tightly.
Once sharpened knives electroplane immediately need to test the blade by removing some shavings.It is proved in practice that the tool blade, which was put into operation immediately after sharpening, blunts less.To avoid frequent sharpening knives on the winepress, watch carefully in the process of the state of the glands, and at the first sign of bluntness (brilliant strips) immediately edit them elektrorubanok on whetstone.
Now you know why it is important to constantly monitor the positions of the blades on the power planners, time to adjust them, remove and install a new piece of iron.In addition, you always have the opportunity to sharpen knives electroplane a special device and put it back.
