The milling cutter of the small milling machine is usually the main movement of rotation, and the movement of the workpiece (and) the milling cutter is the feed movement. It can process planes, grooves, and various curved surfaces, gears, etc. A small milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads and spline shafts, small milling machines can also process more complex profiles, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.

Daily maintenance of small milling machines needs attention
1. Cleaning of bed and parts, cleaning iron filings and surrounding environment, cleaners, clamps, measuring tools
2. Check the oil level, not lower than the oil mark, add lubricating oil to each part
Routine maintenance of small milling machines should pay attention to:

1. Cleaning of small milling machines
1. Disassemble and clean the oil felt pads of various parts
2. Wipe the sliding surfaces and guide rail surfaces, wipe the table and the horizontal direction, lift the screw, wipe the knife transmission mechanism and the knife rest
3. Wipe the dead corners of all parts.

2. Lubrication of small milling machines
1. All oil holes are clean and smooth and filled with lubricating oil
2. Fill lubricating oil on each guide rail surface, sliding surface and each screw rod
3. Check the oil tank body and oil level of the transmission mechanism of the small milling machine, and refuel to the elevation position

3. Tighten the small milling machine
1. Check the small milling machine and tighten the pressure plate and insert screws
2. Check and tighten the fixing screw of the slider, the knife transmission mechanism, the hand wheel, the screw of the table bracket, and the fork top wire
3. Check and tighten other loose screws

4, small milling machine adjustment
1. Check and adjust the tightness of belts, pressure plates and inserts
2. Check and adjust the sliding block and lead screw

5. Anti-corrosion of small milling machines
1. Remove the rust of each part, protect the painted surface, do not collide
2. The small milling machine is deactivated, the guide rail surface of the spare equipment, the sliding screw handwheel and other exposed parts that are easy to rust are coated with oil and anti-corrosion

The correct and good maintenance of the small milling machine plays an important role in its life and machining accuracy. Therefore, we must pay attention to the status of the small milling machine before, during and after daily processing.
