厨房和浴室升级的热门选择，抛光和密封花岗岩具有永恒的诱惑，耐用性和低维护少数其他材料可以匹配。但这种天然的石头昂贵，每平方英尺15美元至40美元，专业安装每平方英尺加入另外25％至35美元。节省可观现金的一种方法your dreamy update? Learning how to cut granite yourself.
花岗岩非常密集，很难，所以你必须继续耐心和正确的工具来完成工作。以下是您需要成功削减花岗岩板（通常为1¼“厚的所有指导，但为您的家庭改善项目提供最多1½”厚的“瓷砖（约3/8”厚）。

Cutting a Granite Slab
第1步
Choose either a standard circular saw or a wet-cutcircular saw切花花岗岩。要么工作，但湿式圆锯会产生很小的灰尘，感谢像你切割的小管子淋上水面上的花岗岩表面。如果可能，请切割花岗岩平板户外，以简化清理。
第2步
Position the granite slab on a sturdy work surface, and use C-clamps, attaching one every couple of feet along the sides of the slab, to secure it tightly. A designatedworkbenchworks well, but avoid placing the slab on a something that could shift, such as sawhorses. By securing the piece with clamps, you’ll reduce vibration and movement of the slab, both of which can lead to chipping.
第3步
穿着防尘罩，安全护目镜和耳保护来保护自己。切割花岗岩是响亮的，这是一个没有湿圆锯的尘土飞扬的前景。
STEP 4
Cover the section of花岗岩you intend to cut with painter’s tape. Because the tape will simply serve to protect the surface and reduce the risk of chipping, the placement of the tape needn’t be precise. Just place two or three strips along the topside in the general area where you’ll be cutting—you’ll be cutting right through it.

STEP 5
Measure carefully and make a cutline on top of the painter’s tape with a marker. The wise carpenters’ adage of “measure twice; cut once” applies here. Take your time and recheck your measurements to ensure you’ll be cutting in the exact place. When cutting granite, you’ll have only one chance to get it right.
STEP 6
适合标有用于切割花岗岩的金刚石刀片。然后，从切割的末端进行短暂的“后切”长约两英寸。这将降低风险花岗岩chipping as you cut from the other end and reach this spot.
Making the back-cut is a must because the granite material becomes very thin just before the sawblade breaks through the last bit of stone at the end of the slab. Without the back-cut, vibrations from the saw could likely cause chipping or even break off a chunk.
STEP 7
After making the back-cut, reposition the saw at the opposite end of the slab and cut slowly along the cutline. Focus on keeping the blade aligned precisely on the cutline and maintain light and steady pressure on the saw without forcing it, letting the blade do the work. Use the same light pressure until you’ve finished the cut. Depending on the length of the cut, this could take 15 minutes or longer.
STEP 8
Peel the tape from the granite and admire your smooth, clean cut. Allow the granite dust to settle and suck it up with a shop-typevacuum. If you used a wet-cut circular saw, you’ll find a thin wet slurry instead of dust; wipe this off the slab with a damp rag. Slurry left on a sidewalk or driveway can be easily rinsed away with a garden hose.

Cutting Granite Tile
第1步
Make cuts in granite tile with a wet-tile saw. Unlike a circular saw, which is handheld, a wet-tile saw is stationary and the tile rests on a sliding table. Wet-tile saws vary widely; some come with lasers to help align thetiles, adjustable guides, or the ability to make beveled cuts, but they all work on the same principle.
第2步
Fit the tile saw with a diamond blade labeled suitable for cutting granite. A blade designed tocut ceramic tile或大理石我sn’t adequate. Granite is harder than ceramic and marble—a blade designed to cut those types of tile will barely make a dent in a granite.

第3步
Carefully measure how much you need to cut from the tile and then make the cutline with an indelible marker. A regular marker can wash off while cutting granite. Any errant ink that remains on the tile post-cut can be removed with a bit ofrubbing alcoholon a rag.
STEP 4
用水填充湿瓷砖上的水库，然后用水填充“填充”线。
STEP 5
将瓷砖放在滑动台上，并将切割与刀片对齐。使用指南将其固定到位。（如果您对机器上的指南有疑问，请检查您的所有者手册。）
STEP 6
打开锯，仅在滑动台上使用光线向前压力;让刀片的旋转运动做大部分工作。当你削减花岗岩时，水就会在刀片和瓷砖上自由流动，消除dust, cools the blade, and reduces the risk of chipping.
STEP 7
在从滑动台上拆下剪切花岗岩瓦片之前，关闭锯。排出瓷砖锯储存器，用抹布擦拭任何溢出或喷溅的水或浆料。水管沿着常规的户外表面garden hose如有必要。
