How long do milling apprentices usually study?

I'm afraid it will take more than a year to operate completely independently. From basic operations, such as machining plane, drilling and sharpening. There are no steps, grooves and special-shaped surfaces with high machining accuracy in a year. Even if someone teaches you, it will take months to practice.

Milling machine mainly refers to the machine tool that uses milling cutter to process various surfaces of workpiece. Usually, the milling cutter is mainly rotating, and the movement of the workpiece and milling cutter is feeding. Can process planes and grooves, as well as various curved surfaces and gears.

Milling machine is a machine tool for milling workpieces with milling cutter. Milling machines can not only mill planes, grooves, gear teeth, threads and spline shafts, but also process more complex contours, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.

Safe operating procedure

First, you must wear work clothes when entering the workshop. Gloves are not allowed to be worn during operation (to prevent gloves from hanging on the cutting knife and causing accidents), and female students must wear working caps (to prevent the hair from being caught in the machine because it is too long).

Second, before driving, check whether the handle position of the machine tool and the tool clamping are firm and reliable, and whether the tool movement direction and the feeding direction of the workbench are correct.

Three, the oil hole, idling test (winter must first drive the local train) for more than 2 minutes, check the oil window and other parts, and listen to the sound is normal.

Fourth, when cutting, start the car first If you stop halfway, you should stop feeding first, and then stop after withdrawing.

5. Concentrate, stick to your post, stop when you leave, and the machine tool is not allowed to be overloaded.

Six, the workbench is not allowed to accumulate too much iron filings, tools or other objects are forbidden to be placed on the surface of the workbench and railings, and tools should be placed in the designated position.

Seven, cutting, it is forbidden to use the brush in the same direction as the cutter to clean iron filings or add coolant.
