Schunk lighter steel version Rota NCL lathe chuck secures acceleration and power saving benefits
1 min read
The steel version of the Rota NCL lathe chuck weighs about 35% less than conventional power chucks of the same size, says Schunk, so faster acceleration and reduced energy consumption are possible. A new type of double cylinder guidance of the base jaws ensures that the forces are evenly distributed on the chuck body.
Schunk development engineers have rigorously reduced all possible dispensable weight on the Rota NCL lathe chuck. Its very flat design incorporates three striking flanks in the interests of lightness, optimum accessibility and design. Numerous holes inside the chuck additionally also reduce the unit's weight.
All the components in the force flow are made of very strong hardened steel to safeguard the chuck's clamping force, rigidity and precision. A double cylinder guidance system, which is being patented, ensures the forces are evenly distributed on the chuck body. The Schunk Rota NCL is suitable for inside and outside diameter clamping due to the optimum jaw support. Integral permanent lubrication supports constant clamping forces, and thus for a constant efficiency, underlines the company.
The Rota NCL lightweight lathe chuck is hermetically sealed against dust and coolant and is mostly maintenance free. Its compact height leaves plenty of space in the machine envelope. The interface between base jaw and top jaw is tongue and groove, for which numerous standard chuck jaws from the world's largest Schunk chuck jaw programme can be quickly and precisely exchanged. The 185, 225 and 260 lathe chuck sizes available offer clamping forces between 75 and 140 kN.
