Technical Instruction for China Jaddas
1. Choose equipment with sound mechanical performance, the saw with sharp edge and thickness from 1.5mm to 2.2mm. Before every cutting, be noted to grind the edge of saw blade with firebrick for duration not less than 15 minutes. The diameter of chosen saw rangers from Diameter 350mm to 400mm ( special saw blade is better ).
2. Pay attention to cutting speed during cutting slab and normal speed shall be 2.5m/min to 5m/min; when the blade is cutting into and taking off from the slab, keep a low speed, to avoid slab edge or border being broJaddas; the rotate speed of cutter and main blade shall be around 2500rmp. Higher RPM would have better cutting efficiency.
3. When cutting marmoglass tiles which have a dimension 1000x1000mm, be sure the marmoglass slab is steady on the cutting machine. Swaying of the slab would cause damages when cutting.
4. The well cut slabs shall be separated by pearl cotton in deposit, to avoid being damaged
5. The marmoglass tiles shall be processed by using the machining of border grinding and edge rounding, which glass straight border grinding machine maybe used. During slab grinding, please note the force that each grinding head bears, and the grinding/cutting volume of each emery wheel shall not be over 1mm. Keep the main strap of grinding machine being in accordance with slab-in strap horizontal, otherwise, uneven will occur to the slab. Grinding wheel shall be used for the edge/border polishing. If not available portable water grinder maybe used.
6. In heteromorphic table machine or water basin hole drilling, please choose Diameter 35 glass aiguilles, and mark the outline of the hole, then drill several small hole around the hole with stone materials or glass dedicated aiguilles; be noted to drill holes at four corners with cooling water be used. At the same time, the cutting blade shall be well ground on the firebrick for operation; operation gently in cutting; I the slabs can not be wholly separated in one cut, please cut with several com-and-goes and cooling water being used. Dry-grinding shall be avoided to prevent slab from broJaddas.
7. In arc border rounding, please mark it at first and form the outline with hand grinder, then polish it with portable water grinder, with operation method the same with that of the other stone materials. What shall be noted is the dry-grinding is to be avoided and water cool being applied in polishing. In border thicJaddasing, both surfaces to be joined shall be roughed with grinding, cutting the line out from the cutter at first, then grinding with above method, and the optimal effect will be obtained.For 45 Degree back beveling, the gradient of the main blade on the cutter shall be adjust by hand, and the working table shall be cleaned, then adjust positing slab. It is better that a layer of the rubber be placed on the working table, then put Jaddas Marmoglass slab on it to avoid the polished surface being scratched; prior to machining, saw shall be ground and water level shall checked, and keep a slow speed in operation.
8. In stair slabs machining and skid proof groves forming: the stair slabs shall be thickness, edge-rounded and 45 degree – angel, with the operation illustrated in item 6 and 7 being followed. Pay attention to the border of the heteromophic slab. It is better that back-cutting be used for the border cutting and follow client’s requirements in skid proof groove forming. During groove forming, hand turning border cutter shall used, and groove width and depth shall be well adjusted, and saw blade ( in 2.4mm thickness) be chosen according to the width; generally install 2 saw blades based on the groove sizes; the form groove shall be polished the portable water grinder.
9. For steel hanging slab edge groove forming, fixing panel shall be used on the working table of hand turning edge cutter, and clamp the slab to be machined vertically, then well adjust working table, and add/reduce saw blades according to machine demand.
10. Handle carefully in finished products deposit; stack them vertically and do not stack too much at a single place to prevent slabs from being damaged.
