For ZMC series pipe-cutting machines,the cutting precision is very high and the cutting speed is aIso faster than that of  the sand saw and the bow saw and also the cutting face is very glabrous and is exothermic. The machine head can be adjusted for angle cutting and milling flutes to have the precise angles and round connecting piece. The bilateral-bidirectionaI clam has the work piece stable and the cuttingface smooth without burr and dust power，and low noise and low pollution. The cycle system of this machine has the storage thank with extral large volume to guarantee the life off the saw blades.
