Using MJ3210A band sawing machine with carriage, aiming at the common lever press type automatic tensioning system, according to the method of L25 orthogonal test, the main shaft speed of saw wheel, the weight of press block, the distance between top and bottom sawing cards, and the feed speed were taken as the factors.The transverse vibration displacement signal of the intact saw blade was collected and measured, and the test data were analyzed.The main factors affecting the transverse vibration displacement of band saw blade were the speed of the sawing wheel, the feed speed, the weight of the tub, and the distance of sawing card from big to small.The influence law of each factor was not monotonous, there was certain reasonable range. Through the data analysis, it is concluded that the optimal combination is A2B4C4E1, which makes the transverse vibration displacement of the saw blade smaller. That is, the spindle speed of the band saw wheel is 760 r/min, the weight is 95 N, the distance between the saw and the card is 600 mm, and the feed speed is 12 m/min, the transverse vibration displacement is 1.239 mm.
