Multiscene SKD61 Auto Turned Parts Knurled Nuts Black Oxide Finish
Processing & Inspection Machine List.pdf
A nut, a part that is screwed together with a bolt or a screw for fastening. It is a kind of original that must be used in all production and manufacturing machinery. There are many kinds of nuts. We commonly have national standard, British standard, American standard, Japanese standard. Standard nuts. Nuts are divided into carbon steel, high-strength, stainless steel, plastic steel and other types according to different materials. According to the product attributes corresponding to different standard numbers in different countries, they are divided into ordinary, non-standard, (old) national standard, new national standard, American-made , British, German standard.These standards can be found on the website or in mechanical manuals, or can be found using mechanical design software.
Hua Bao has very rich experience in the production of non-standard screws, bolts and nuts. We can produce various types according to customer requirements, need knurling or not, material is aluminum or steel, need heat treatment or not, need electrochromic treatment or black treatment, we can all produce. For some standard fasteners, we also have corresponding suppliers to provide cooperation. We welcome customers to provide drawings and samples to inquire.

FAQ:
Q1: Can knurling be done by hand?
A: Knurling can be done either by machine or hand. Hand knurling uses a rolling roll that creates the desired pattern on the workpiece.
Q2: What is mechanical knurling?
A: Knurling is a mechanical process of rolling patterns on the knobs of metal products or other working surfaces, mainly for anti-skid purposes. And used in many hardware, mold, and mechanical components.
Q3: How is knurling measured?
A: For diagonal knurl wheels, the *TPI is measured perpendicular to the teeth or helix angle. The circular pitch measurement in inches, is derived from 1 inch divided by the number of Teeth per Inch with the exception of 14, 21, and 33 TPI.
Q4: Is knurling a turning operation?
A: The variation of tool ends and a kinematic relation between the tool and workpiece results in different operations on a lathe. The most common lathe operations are turning, facing, grooving, parting, threading, drilling, boring, knurling, and tapping.
Q5: What is knurl size?
A: Knurls can be supplied in various types, in either circular or diametral pitch, to suit individual requirements. The four diametral pitches available are 64, 96, 128 and 160. A large variety of knurl blanks are regularly carried in stock, insuring fast delivery on special knurls made to customer's specifications.
Q6: How deep should a knurl be?
A: How “deep” to knurl? A fine knurl is 0.010-0.015 inch, a medium knurl 0.015-0.025, and a coarse knurl 0.025-0.035.
Q7: Can you knurl aluminum?
A: Knurled finishes on aluminum are one of our most popular metal finishes. Knurling is a visually attractive diamond shaped pattern cut or rolled into metal. This pattern allows you to get a better grip on the knurled object than would be provided by the original smooth metal surface.
Q8: What is straight knurling?
A: Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled or crossed lines is rolled into the material.
