What is used for knurling?
A knurling tool is a manufacturing and repairing tool used on lathe machines. A knurling tool is used to give the metal a criss-cross pattern shape, which helps the human hand to hold the knurled tool more firmly.
What type of operation is knurling?
Knurling is the operation of producing straight lined, diamond-shaped pattern or cross lined pattern on a cylindrical external surface by pressing a tool called knurling tool. Knurling is not a cutting operation but it is a forming operation. Knurling is done at a slow spindle speed (1/3 the turning speed).
What is knurling process lathe?
Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled or crossed lines is rolled into the material.
What is turning and knurling?
Centre Lathe turning operations – Knurling. Centre lathe turning operations – Knurling. Knurling is a process of impressing a diamond shaped or straight line pattern into the surface of a workpiece by using specially shaped hardened metal wheels to improve its appearance and to provide a better gripping surface.
Does knurling remove material?
Knurling is the process of creating a pattern on a workpiece to improve the visual appearance or to create a better grip on the part. Knurling uses the tool to displace material.
What materials can be knurled?
They are used on steel, brass, aluminum alloys and hard plastics. Knurls have V-shaped teeth that deform, displace or push the material rather than cut it. The embossed patterns can be decorative, but more often act as hand grips and are commonly seen on handles, knobs or rollers.
What are the different types of knurling tools?
According to the patterns produced, the knurled portions are called straight knurling, cross knurling or spiral knurling.

What is the speed used for knurling?
For convenience, Knurling is often performed at the same speeds used for turning operations when using high speed steel tool bits. But to prevent seizing of the rolls on the pin, we recommend a maximum surface speed of about 150 SFPM (Feet/Min) or 50 m/min.
What is the process of knurling on a Centre lathe?
The lathe is set so that the chuck revolves at a low speed. The knurling tool is then pressed against the rotating steel and pressure is slowly increased until the tool produces a pattern on the steel. The automatic control lever is engaged which starts the automatic traverse of the saddle.
