<h3>Technology of partial high-speed project is like this:</h3>
<p>1.Ultrahigh part of the precast and cast beam can be pointed out the area by ruler to find the general area, marked with chalk or paint the error value.</p>
<p>2.Grinding coarsely with a small milling machine, motor gasoline milling is also ok, which depending on the site power conditions.</p>
<p>3.A small milling machine can milling (grinding) the girder around 3-5mm, repeated milling can grind down 1-2 cm.Of course, you can buy bigger one for beam surface with too big difference, for example, a milling depth about 10mm.
</p>
<p>4.Measure after milling machine roughed, continue milling if the depth is not enough.Accurate grinding and lighting by grinding machine after the elevation measurement qualified .</p>
<P>Other fraternal units use shot blasting machine for treatment , but higher construction costs, efficiency may not be faster than the milling machine, but the treated surface is relatively flat.</P>
<P>Treatment effect of bush hammer and milling machine is similar, but bush hammer is vertically to beam surface, which is easy to damage the internal structure of cement concrete, and the need for external air compressor and trachea, not as easy as the milling machine, nor as good as high-efficiency milling machine.</P>
<p>It need to attention, since some small milling machine is very light weight, small number of blades, the power is not large, the effect is almost same as the grinding machines.</p>
<P>Recommended the milling machine with self weight at least 200 kg, engine power 9-13 horsepower, 100pcs or more for blades. There are several manufacturers of small milling machine is mature in recent year. Price compared with similar imported milling machine is nearly 50%.</P>
