The hairline finishing machine is used to create hairline scratches on the surface of metal workpieces, enhancing the aesthetic appearance of the product. Learn more about this equipment in the following article
1.What is a hairline finish, and why is a hairline finishing machine used?
A hairline finish consists of fine, hair-like scratches on the surface of metal sheets, such as stainless steel or steel. These lines enhance the aesthetic appeal and give the product a more refined, premium appearance. Today, stainless steel products such as elevator panels, sinks, medical equipment, and kitchen cabinets are commonly processed with a hairline finish using specialized machinery.
Hairline finishing machine for creating linear scratches on metal surfaces
Instead of leaving the product surface smooth, manufacturers create visual highlights by applying hairline scratches. Hairline finishing produces fine, linear scratch patterns on stainless steel surfaces. This process is carried out at the final stage, after all rough, intermediate, and fine polishing steps have been completed.
There are two basic types of hairline stainless steel: fine short line hairline and long line hairline. Long line hairline stainless steel is commonly referred to as No4. Fine short line hairline stainless steel can be processed manually; however, to achieve higher productivity and better consistency, manufacturers typically use automatic and semi automatic hairline finishing machines.
2. What components does a hairline finishing machine include?
A hairline finishing machine includes equipment such as double spindle machines, surface grinding machines, and sheet type grinding machines. In addition, hairline scratches can also be created using abrasive belts on belt grinding machines with two or three rollers, or on multi station grinding machines equipped with abrasive belts.

Among these, surface grinding machines and sheet type grinding machines are specifically used to create hairline finishes on large stainless steel sheets, such as elevator panels. These machines are automatic types that operate based on pre programmed settings. Double spindle machines and belt grinding machines are semi automatic mechanical grinding machines. Both types require human operation and control.
The primary consumable used for creating hairline patterns is the felt wheel. Felt wheels are composed of felt fibers, abrasive grains, and industrial adhesives. The felt fibers and abrasive grains are arranged in multiple mesh like layers, then compressed at high temperature together with adhesives and premium additives.
Through direct friction with the metal surface, the felt wheel produces fine hairline scratches. This abrasive material is used at the final stage, after the metal workpieces have achieved the required smoothness and brightness.
Abrasive belts can also be used to create hairline finishes when fine grit sizes of approximately #400 or higher are applied.
