The CNC gantry milling machine has the functions of a milling machine, a boring machine, and a drilling machine, so that the process is highly concentrated.
When replacing a workpiece, only the processing program, clamping tool and adjustment tool data stored in the CNC device can be called, thus greatly shortening the production cycle. Improve production efficiency.
Different types of CNC gantry milling machines differ in composition. The main difference comes from the types of components and their design and assembly methods. For this reason, let's understand what types of CNC gantry milling machines are:
The first is the parts used for precision structures. Precision mechanical equipment has high requirements for the stability of the fit. It is required that the wear limit of the parts does not exceed 10% of the dimensional tolerance value of the parts during use or after multiple assembly. This is mainly applied to the surface of precision instruments, meters, precision measuring tools, and the friction surface of important parts, such as the inner surface of cylinders, the main journal of precision machine tools, and the main journal of coordinate boring machines.
Sub-precision structure parts have higher requirements for the stability of the fit. The wear limit of the parts is required to not exceed 25% of the part's dimensional tolerance value, and a well-closed contact surface is required. It is mainly used in machine tools, tools, The mating surface of the rolling bearing, the taper pin hole, and the contact surface with higher relative movement speed, such as the mating surface of the sliding bearing, the tooth working surface of the gear, etc.
In addition, there are some general parts, there is no contact surface of relative moving parts, such as box cover, sleeve, surface that requires close contact, key and keyway working surface.
