Silent-Power® helical planer spindle makes the difference when investing in a thickness planer and straightener

The Silent-Power® helical spindle offers technical and economic advantages that make the difference every time. Perfect planing results, quiet operation, 20 times longer knife life and low energy consumption are just some of the advantages it offers to furniture manufacturers worldwide.  

The Silent-Power® shaft is a Felder Group innovation, unique in the world.

In more than 60 years of experience and tradition in the production of furniture manufacturing machinery, the Felder Group has proven not only that it can produce quality machinery, but that it is also one of the most innovative companies in the industry. Numerous patented and award-winning innovations over the years are a testament to the commitment of Austrian engineers to delivering quality solutions for quality furniture.  

Recognized by manufacturers around the world for its machining precision and long service life, the Silent-Power® helical Silent-Power® flap spindle has become one of Felder Group's best-known innovations for the classic machine segment.  

Felder engineers have created a solution unique in the market that not only offers machining accuracy, but also time savings, low maintenance costs, low operating noise and long tool life. It is no coincidence that Silent-Power® comes with a 3-year warranty.  

Silent-Power® is a Felder Group patented innovation found only on the Felder Group's portfolio of thicknessing and straightening machines.

The Silent-Power® helical Silent-Power® helical machining spindle offers the technical and economic advantages that make the difference every time:    

• Get perfectly flat surfaces, without any veiling effect thanks to the helical knife arrangement. 
• Save money and time with 4 cutting edges that last 20 times longer than conventional knives. 
• You'll have less noise in the workshop because the spindle generates 50% less noise than conventional planing spindles.  
• You have a low volume of sawdust collection due to the small size of the chips resulting from processing. 
• You have lower energy costs thanks to shear cutting action.  
• Benefit from a 3-year warranty through the G+ extended warranty program.  

⇒ Get perfectly flat surfaces: helical arrangement of knives

The helical arrangement of the knives on the spindle means that chipping is done gradually, and this prevents the appearance of veeling on the surface being planed. With the Silent-Power® spindle you get the results you need when straightening and thickness planing, so you invest less time and effort in the sanding stage.

⇒ Save money and time: 4 cutting edge knives with 20 times longer lifetime 

The Silent-Power® shaft knives have a longer life cycle because they are made of a very strong material (tungsten carbide) and have 4 cutting edges, which gives a life 20 times longer than that of classic knives (standard HSS blades). When one of the cutting edges of the knives wears out, you have three more cutting edges to use before replacing the knives completely.

⇒ You benefit from quiet operation: noise reduced by 50% compared to conventional shafts

The Felder Group's patented helical shafting does not bear the name Silent-Power® by chance. It generates 50% less noise than conventional shafts. With noise in carpentry workshops and furniture factories being a risk factor for occupational health and safety, the reduced noise level contributes to improved working conditions for operators. 

In the video below you will see a comparison between machining with the Silent-Power® spindle and machining with a classic 4 cutter spindle, including decibel level demonstration.

⇒ Savings from day one: smaller chips, higher collection volume 

Another advantage of the helical arrangement of knives with 4 cutting edges is that the contact surface of each individual knife with the material to be processed is reduced, resulting in smaller chip sizes than when machining with a conventional spindle. The smaller chips are easier to vacuum and take up less space in the exhaust bag. This saves processing time by changing the exhaust bags less often and saves storage space for the sawdust.

⇒ Lower costs: reduce energy consumption by 20%

Among the major advantages of the Silent-Power® helical spindle is its low energy consumption. The cutting action is shearing, which results in 20% less power consumption than other machining spindles. 

See in the video below a demonstration of the energy consumption of the Silent-Power® shaft compared to a regular shaft.

⇒ Simple knife change: quick and easy tensioning 

Changing the knives is simple with a screwdriver. You can use a torque screwdriver for faster and more secure fixing. This includes a precisely adjusted ratchet system for optimal tightening of the knives without damaging the fixing screws.
