Knurled shaft
 I produced a variety of precision knurled shaft, includes a knurled shaft / shaft core / Pin/step shaft products:I imported automatic lathes, good at processing all types of shaft parts, And the axis of the core used on various electronic products, plug rotary shaft. Material by the customer first choice. Welcome to plans to order. The left picture shows a copper and stainless steel PIN pin with knurl applied to plastic. There are two kinds of material. One is brass C3604, the other is stainless steel SUS303, the largest knurling outer diameter 8MM, total length 50MM. The top is a sharp cone angle the role of the thimble. Below this page is an enlarged view of two knurled shafts of the same size in different materials. A custom copper positioning pin Material: copper C3604 Specifications: 6.2*25.9 Knurled shaft with edge milling Material: 11L44 medium carbon steel Surface treatment; quenched HRC50, trivalent chromium environmental nickel plating Product Application Electronic Equipment Rotary Shaft Used for embossing small shafts and knurling axes Features: One end pressure netting pattern. Anti-slip function after embedding in plastic pieces. The left figure is 12L14 fast cutting steel, galvanized surface. The knurled shaft acts as a mechanical part that supports the rotating part and rotates with it to transmit the movement, torque or bending moment. Generally round metal rods, each segment can have different diameters. Parts that make a rotary motion in the machine are mounted on the shaft. Material plus chrome embossed small shaft Material: C3604 fast cutting brass Surface treatment: color (left), chrome plating (right) to prevent appearance and rust Size: 5.0*20 inner hole 2.0*10 Application: The lower part with pressure lines is injected into the plastic part, and the upper part of the bare rod is exposed. Slender shaft  The left picture shows a slender shaft with grooved milling and threads, and an elongated shaft with knurls. hardened stainless steel material, HRC50 ~ 55, after the vacuum heat treatment centerless grinding, so that the bright surface, and straight and high.One end has a thread M3 and the other end is notched and a facet is milled in the notch. Precision turned parts, smooth surface without cutting marks, toy shaft. Material: Stainless steel Slotted at both ends or grooved at one end and threaded at the other end. The surface is ground to an accuracy of 0.8um Can produce various types of step parts, knurled shaft, shaft core, computer shaft, toy shaft, micro-motor shaft with threaded shaft. Widely used in toys / electrical surface / electronic / computer / assembly industry. Surface treatment: fast cutting steel is generally electroplated, copper is generally nickel-plated, stainless steel generally do not have to electroplating According to the different axis shapes, the pin axis can be divided into two types: crankshaft and straight axis. According to the bearing condition of the shaft, it can be further divided into: spindle shaft and transmission shaft, When the work is both bending moments and torque to bear, it is the most common mechanical axis. The mandrel is used to support the rotating parts and only withstand the bending moment without transmitting the torque. Some of the mandrels rotate, such as the mandrel of the flip phone, and some mandrels do not rotate, such as the shaft supporting the pulley. |
Ball head Screws
 The head is a round or spherical screw, as shown on the left, it is made of hexagonal rods, and the middle is hexagonal to facilitate the use of wrenches. The head ball is made by molding knife turning. Smooth Surface Effect (Spherical Visible Reflector)Specifications to the left: Thread M3* Hexagonal edge H6* Total length 12mm Left Material: Quick-cut steel, nickel-plated Production of Ball Screws Specifications: Threads from M2 to M12, products are within outer diameter H17 Available ball screw materials: carbon steel (usually we use fast cutting steel), copper, aluminum, stainless steel, etc. Ball head screws (head hex socket)  The Ball head Screws on the left are not the same as the Ball head Screws on the figure above. The above figure shows the installation of the hexagon wrench. The left figure corresponds to the hexagon in the figure above, which is a circle, so a hexagon hole is designed on the ball head to facilitate the installation of the Allen wrench.Left figure material: aluminum Its spherical surface is as smooth as the surface Note: We did not use post-processing (such as polishing) for the effectiveness of these conditions. This is a one-time completion of automatic turning with a forming knife. We just grind the knife edge while making the forming knife, producing beautiful products. |
