The downward force required to deform the rivet with an automatic riveting machine is created by a motor and flywheel combination, pneumatic cylinder, or hydraulic cylinder. Manual feed riveting machines usually have a mechanical lever to deliver the setting force from a foot pedal or hand lever.

Spin riveting machines can be sub-divided into two broad groups —radial riveting machines and orbital riveting machines.

Radial riveting is subtly different from orbital forming. Radial riveting lightly peens (hammers) the rivet head into the desired shape whereas orbital forming spreads the rivet head in one, continuous contact, motion. While orbital forming is the superior process in most applications, spiralform riveting can produce better results when very small rivets are involved.

The motor drive main spindle by connected coupling,meanwhile the main spindle transfer the movement to Spherical kinematic pair by Gear planetary mechanism, the high pressure hydraulic system drive piston moving down and powerhead contact with the rivets, powerhead turn circles following 11 disc plum trajectory around the center line of spindle to perform riveting.

Radial riveting machine adopts the most advanced 11 disc plum rolling technology , the rivet material deformation along diameter direction, and form a cellulosic surface that is tangent to the working load, thus improving the ability to resistance load. This technology of static riveting ability is perfect. It may apply to process electric plating rivet without damage the coating, also it can be used to rivet plastics and ceramic materials if the appropriate feeding and pressure adjustment. In addition the riveting stability is very good, generally it can also complete riveting smoothly even if the rivet misalignment or non-clamping. Due to the radial riveting force is smaller than that of orbital riveting, thus riveting effects is no bad deformation (rod bending, pier thick), smaller internal stress, no crack, zero rejection rate.

Orbital riveting machine adopts the technology of the cold pendulum grinding forming, riveting quality is slightly lower than the radial riveting. Riveting material deformation is along the circumferential direction, form a round cellulosic flow, resistance load is a bit lower than that of radial riveting machine. Generally it can complete riveting under the conditions of rivet relatively alignment and tightly clamping, it will produce a little bit of internal stress.

Radial riveting can produce better results when very small rivets are involved.Radial riveting machine can be used in a wide range of applications that not only cover the scope of Orbital riveting machine, but also can be used for processing semi-enclosed workpieces, static locking type workpieces,larger length worpieces,even plastics material and ceramics material.

Orbital forming is the superior process in most applications, It is more applicable for larger size work pieces, Orbital riveting machines are used in a wide range of applications including brake linings for commercial vehicles, aircraft, and locomotives, textile and leather goods, metal brackets, window and door furniture, latches and even mobile phones. Many materials can be riveted together using orbital riveting machines including delicate and brittle materials, and sensitive electrical or electronic components.

The advantages includes safety devices, good riveting quality ,smooth surface, non-deformation, low energy consumption. high efficient and reliable operating.

The advantages includes safety devices, good riveting quality, low energy consumption,high efficient, and reliable operation, low noisy( a little bit higher than radial riveting machine).

The Radial riveting machine price is around 2% more than Orbital riveting machine, however its performance price comparison is higher by 10% than that of Orbital riveting machine.The rivet head and mould cost only 18-40USD per piece while it could be used more than 2 years.

The cost is lower than radial riveting machine
