The thread cutter is located on the underside of a needle plate where there is a needle hole that cuts needle and bobbin threads located between a piece of cloth and a rotary hook.
Thread tension dial
The thread tension dial is used to regulate the tension discs to tighten or loosen at the time of sewing. This dial helps to stitch properly by maintaining the proper tension level.
Face plate is used to cover the oiling points of the needle bar, presser bar, and thread take-up lever. This project is from the unwanted contact of needle bar, pressure bar, and any other foreign particles.
