Because too much friction can damage the simple machines that make up the compound machine.
Reducing friction on a machine can lead to smoother operation, less wear and tear on moving parts, and reduced energy consumption. However, it can also reduce the stability or control of the machine in some cases.
No, an ideal machine is usually considered to be frictionless to simplify calculations and convey fundamental concepts. In reality, all machines have some level of friction, which can reduce efficiency and introduce energy losses.
If I'm not mistaken, there is no machine that can reduce friction. The machine is intended to change the distance the input force is applied over or to multiply the output force. The moving parts of the machine will always increase friction. In order to reduce the extra friction (but not completely remove it), one would use a lubricant or reduce the roughness between two surfaces. Hope it helps.
You could add lubricants like oil or grease to reduce sliding friction on the moving parts of a machine. Additionally, using materials with lower coefficients of friction or adding bearings or rollers can help to minimize sliding friction. Regular maintenance and cleaning of the machine parts can also help prevent friction buildup.
While a well-oiled machine may experience reduced friction compared to a dry one, it will still have some level of friction. Friction is inherent when two surfaces come in contact, even with lubrication. The goal of lubricating a machine is to minimize this friction and reduce wear on the moving parts.
Oil it

I think it would a lubricant not a part...

Friction force oppose motion between two bodies that are in contact. This force is important in machines and pulley systems in that it enables the gears to have grip and there is no unnecessary sliding.
Because some energy is expended in overcoming the friction and not applied to performing the task which the machine is meant to do.
Yes, a well-oiled machine can still have some friction, but the oil helps to reduce it. Friction occurs when there is resistance between moving parts, and the oil acts as a lubricant to minimize this resistance. Regular maintenance and lubrication are essential to keep friction to a minimum in a well-oiled machine.
You can reduce friction by using lubrication, like grease for bearing, sewing machine oil etc.
Friction creates heat. Heat could melt machine parts if it becomes too high. That's why many machines use lubricants while they're drilling or shaping metal.
