Gantry milling machine operating procedures
Gantry milling machine, referred to as gantry milling machine, is a milling machine with a portal frame and a long horizontal bed. The gantry milling machine can use multiple milling cutters to machine the surface at the same time, and the machining accuracy and production efficiency are relatively high. It is suitable for machining the flat and inclined surfaces of large workpieces in batch and mass production. CNC gantry milling machines can also process space curved surfaces and some special parts.
Whitney created a horizontal milling machine in 1818; in order to mill the spiral groove of a twist drill, American Brown created the first universal milling machine in 1862, which was the prototype of a lifting table milling machine; around 1884, a gantry milling machine appeared ; In the 1920s, a semi-automatic milling machine appeared, and the worktable could use the stopper to complete the automatic conversion of "feed-fast" or "fast-feed".
The following is the process that the gantry milling machine needs to follow when operating
1. The work object should be clamped with pressure plates, screws or special tools. Do not use a general wrench to add a casing, so as not to slip off and hurt people.
2. The tool should be clamped firmly, otherwise it is not allowed to drive to work.
3. Before working, check the operation of the transmission part of the machine tool, and install the baffle of the machine tool before it can run.
4. When milling various workpieces, especially rough milling, slow cutting should be performed at the beginning.
5. When moving the worktable and the tool rest, the fixing screws should be loosened first.
6. When loading and unloading knives, a copper hammer or a mallet should be used to lightly strike to prevent knife fragments from flying out and hurting people.
7. During cutting, it is not allowed to change speed and adjust the tool, and it is forbidden to touch or measure the workpiece by hand.
