The quality of aluminum alloy saw blade sawing and whether the feed drum rotates synchronously, whether the felt is intact and clean, and whether the aluminum chips on the profile surface are cleaned are all factors that have a great relationship, as follows:
1, before the boot to check whether the feed drum is synchronized rotation, to protect the felt is good and clean.
2, machine table is clean, check the material frame or frame, to protect the felt is intact, the material frame bottom and both sides have no screw loose.
3, lifting material to the frame, lifting material height above the frame 10cm or more, put on the frame, to avoid the profile and frame collision, and should be done to gently put.
4, sawing a number of saws to clean the aluminum chips on the platform, and then carry out sawing of the next batch. Many saw cutting mainly pay attention to the press device, to ensure that the pressure and saw cutting are stable, and many saw cutting have corresponding requirements for the number of teeth and angles of the saw blade, and a single saw cutting is different.
During the framing process, the profile should be kept at a certain distance from both sides of the frame. There must be a certain gap between the profile and the profile or be separated from the branch by a high temperature felt branch. Avoid rubbing or touching. After sawing, the profiles must be arranged neatly, with no burrs at both ends, no deformation of the saws, and no traces of oil; Aluminum chips on the surface of the profile should be blown clean to prevent aluminum chips from secondary abrasions of the profile.
6, profile frame must follow the long material in the next, short material in the upper, thick material in the lower, thin material on the placement principle.
In sawing profiles, the latest cooling system is a micro-lubrication system, which can control the amount of oil sprayed and the time between injection, and is controlled by time relays. Ensure that the cut surface of the sawing material is smooth and hairless.
