though it is very good,

dth hammer, it also causes losses to users due to a wrong construction
method of cracks along nail holes. Therefore, drilling in PC endurance board is
a very important technology. Considering that the raw material of the
polycarbonate solid sheet will show thermal expansion and shortening, and thus
its fixing time has a significant effect, the possibility of quality problems
after the item is very high if the nails fixed on the board are not opened
directly. It is necessary to pull the extension to reduce the failure rate of
the solid board. So, how to process the PC endurance board-drilling operation?
The simple way is to use the solid piece piercing bit directly, which can pick a
thicker bit. ? Larger or wobbly holes. The diameter of the hole diameter is
about two thirds larger than the left and right of the nail being drilled. The
rear number is preferably larger. Return to Sohu to see more Responsible Editor:
(function() { function getBrandHtml() { var brands = [],
down the
hole bit, html = ''; for(var i = 0; i < brands.length; i++) { var brand =
brands[i]; if(brands.length i+1) { html+= '
'+brand.name+''; } else { html+= '
'+brand.name+'、'; } }
return html; }; if(document.getElementById('linkBtn')){
document.getElementById('linkBtn').onclick = function() {
$('#brands').removeClass('brand');$ ( '# tipInfo').text ( 'Real name

document.getElementById('brands').innerHTML = getBrandHtml(); }; })();。
