Five factors affecting the service life of woodworking CNC band saw machine
1. The selection of high-quality band sawing machine, correct operation and adjustment of the machine tool are the most important factors to ensure the service life of the band saw blade. Good machine rigidity and working performance can prevent the huge impact of vibration and various stress on the band saw blade.
Second, correctly select the band saw blade you will use. No band saw blade can meet all the requirements of sawing, and various types and characteristics of saw blades have different utility. This choice includes appropriate blade width, tooth shape and pitch.
3. Correctly use the sawing parameters, which mainly include saw blade linear speed, feed rate, saw blade tension, etc. The ideal chip when sawing the material should be tightly rolled, silver and have a warm hand. If sintering, brownish blue, thick or powdery chips appear, relevant parameters need to be adjusted.
Fourth, the correct use of cutting fluid and its mixture can lubricate and cool the band saw blade, and timely clean off the attachments on the saw teeth.
Fifth, "run-in" the new band saw blade correctly, "run-in" is through the natural wear of the saw teeth to remove the burr of the tooth edge, so that the band saw blade gradually enters the normal sawing state, to avoid prematurely causing the collapse of the saw blade and the cutting edge, especially It is especially important when it is a profile, pipe and profiled material whose cross-section changes rapidly. During the “run-in”, the machine parameters should be adjusted to about 50% of the normal sawing efficiency. The sawing area is generally 200-600 cm2. After there are no abnormal conditions, gradually adjust the machine parameters and enter the normal sawing state.
