Knurling - Import export

Specification: There are 2 producion methods of producing the proflie of thread rolling dies: Cutting method: is the traditional way for producing the thread shape of thread rolling dies, the threads are cut by the lathe machine. The thread shapes are with flat tip and flat root. Grinding method: is the newly way of producing the thread shape of thread rolling dies, the threads are ground by the thread grinding machines, teh trhead shapes are with round tip and round root. Why we choose the grinding method for UNIFY thread rolling dies, please check the above for the reason. Currently, we have more then 10 units of REISHAUER thread grinding machines (Swiss made) in our factory. The thread rolling dies offered by UNIFY are always the grinding type. The higher level quality can be ensured!

In respect of rolling the serration type working pieces as the transmission shafts of autobobile/motor-vehicles, spline shaft, and manual tools. The grinding type serration spline rolling dies can be ensured for the precision, delicate and smooth surface, extending the life of the rollers.

For the mass production of fastener screws, it may also another good choice for the flat type thread rolling which may reduce production cost, applied to big-valume production. With the same named tool steel SKD11 (JIS) and SKH9, together with advanced heat treatment technology, and thread grinding CNC machien to offer the customer for another choice.

In feed (Plunge) thread rolling dies: There are multiple starts (helix angle) at the edge of thread rolling dies. The type of thread rolling dies are sutiable to thread rolling of shorter length. the thread rolling progress as: Place a work piece in between of thread rolling dies, the screws are formed by strongly pressing progress, when the right thread rollign die returns, take out the work piece. (the work piece stays at the same rollng point). Thru feed thread rolling dies: The threads are as the rings on the surface of thread rolling dies. The type of thread rolling dies are sutiable to thread rolling longer length of screws. (longer then the length of thread rolling dies) The threading progress as: Set the helix angle with the roller shafts of thread rolling machines first, and insert the thread rolling dies. 1. Place a work piece in between of thread rolling dies, make sure the work piece is clamped by thread rolling dies. 2. The work piece is moving

The knurling die: The knurling pattern with non-skid and attracting in appearance on manual tools (straight knurling pattern or diamond knurling pattern) by the knurling dies. The knurling pattern is formed by gear hobbing machine before the heat treatment process, the precision is less good as the grinding type, but, the straightness, and concertricity can be assured.

The superior tool steel is a very important element of thread rolling dies. SKD11 (JIS) and 1.2379 (DIN) are the named raw material which we have chosen for the past years. The blank of thread rollingd ies are heat treated by Japanese TECHNO vaccum & oil quenching furnace by heat treating dep. (TOYOGEN INDUSTRIAL CO.,) It will render the higher rigidity and higher wear-resistance of thread rolling dies. After the heat tratment progress, the thread rolling dies are ground by Swiss REISHAUER thread grinding machines. And another progress of tempering to reduce the grinding stress is necessary for thread rolling dies. The thread rolling dies are ready for sale after the quality exam. The good quality of thread rolling dies is able to offer higher precision, longer working life, and reduced the cost to customers. We also produce the thread rollingd ies for other brands thread rolling machines. Your special specifications and requirements are very welcomed.

SPIROL's FH200 Headed Straight Knurled Pin has the same body style as the KP200 Straight Knurled Pin, with the addition of a head. A Headed Pin is typically used to provide a positive stop or to retain a thin component to a thicker component within an assembly. FH200 Headed Straight Knurled Pins have a flat head, however they are available to order with a round head (RH200) to meet specific application requirements. Similar to the SPIROL Series KP200 Straight Knurled Pin offering, SPIROL's Series FH200 Headed Straight Knurled Pins are available in metric diameters ranging from Ø2.5mm to Ø6mm and inch diameters ranging from Ø.094" (3/32) to Ø.250" (1/4) in low carbon steel and austenitic stainless steel.

SPIROL's KP200 Straight Knurled Pins have straight knurls that span the full length of the pin. Straight Knurled Pins are commonly used in applications where the pin is subjected to rotational forces to transmit torque as well as to resist rotational movement of a mating component. KP200 Straight Knurled Pins are available in metric diameters ranging from 2.5mm to 6mm and in inch diameters ranging from .094" (3/32) to .250" (1/4) in low carbon steel and austenitic stainless steel.

SPIROL's Knurled Pins are manufactured with two different knurl types: straight knurls and helical knurls. Unlike a Straight Pin, where retention is provided by the uniform interference between the pin and hole, Knurled Pins are designed to cut into the host. The displacement of the host material into the valleys of the knurls yields more frictional contact area between the Knurled Pin and hole; thus resulting in higher retention. Solid Pins with retention features such as knurls and barbs allow for wider hole tolerances than Solid Pins without retention features (i.e. Straight Pins).

The knurled shaft of the blind rivet nut provides a locking device to avoid the turning of the insert in the component. These knurled blind rivet nuts are used preferably in components with lower regidity (component material is less "hard" than the material of the blind rivet nut).They are available with different heads (dome, countersunk and small countersunk) and as open and closed end versions.

Series RH600 Twist-Lok™ Pins replace costly screw machined pins and eliminate problematic installation of screws and rivets. The helical knurl minimises stress during installation by rotating as it engages the hinge. Corrosion-resistant material and a rounded burr-free head improve installed appearance. Axial and radial forces induced in the hinge eliminate the tendency for the pin to creep and maintain hinge tension.

SPIROL designs and manufactures specific types of Solid Pins to meet the performance and assembly requirements of common niche applications. These Solid Pins are variations of our standard product either manufactured from specific material, have a specific finish or undergo specific processing to meet performance, corrosion, compatibility and assembly requirements for the specific application. These pre-designed application-specific series of Solid Pins help companies shorten the design cycle to confidently launch their product quickly to the market with a pinning solution that has been tested and proven within their assembly.

SPIROL's FH300 Headed Helical Knurled Pin has the same body style as the KP300 Helical Knurled Pin, with the addition of a head. A Headed Pin is typically used to provide a positive stop or to retain a thin component to a thicker component within an assembly. FH300 Headed Helical Knurled Pins have a flat head, however they are available to order with a round head (RH300) to meet specific application requirements. Similar to the SPIROL Series KP300 Helical Knurled Pin offering, SPIROL's FH300 Headed Helical Knurled Pins are available in metric diameters ranging from Ø2mm to Ø6mm and inch diameters ranging from Ø.078" (5/64) to Ø.250" (1/4) in low carbon steel and austenitic stainless steel.

SPIROL's KP300 Helical Knurled Pins have helical knurls that span the full length of the pin. The 30° helical knurls cause the pin to rotate during installation into the hole. Helical Knurled Pins offer higher insertion and retention than Straight Knurled Pins. However, KP300 Helical Knurled Pins are not typically recommended when the pin will be subjected to rotational forces as the helical knurl will cause the pin to either "unscrew" itself from the hole or further imbed itself into the hole. KP300 Helical Knurled Pins are available in metric diameters ranging from 2mm to 6mm and in inch diameters ranging from .078" (5/64) to .250" (1/4) in low carbon steel and austenitic stainless steel.
