Explaining The Universe on Instagram: "In machining, lubrication—often provided through cutting fluids or coolants—plays a vital role in controlling heat, friction, and tool wear during cutting operations. As the tool shears material, it generates significant heat, which can cause the tool to dull quickly or the workpiece to distort. Lubricants create a thin film between the tool and the chip, reducing friction and preventing material from welding onto the cutting edge. Coolants help carry heat
