In recent years, the design of advanced industry, manufacturing and biomedicine has become increasingly similar and gradually presents high-precision processing, which urgently requires the production of high-precision parts to realize these designs. New product design and development have stimulated people's interest in machining, a traditional production process with a long history.
As we all know, the precision and performance of Swiss lathes have been widely recognized around the world. This is mainly because the high precision and high quality of Swiss machine tools can meet the needs of various precision processing. The realization of this high precision and high quality is due to Switzerland's long-term accumulation and superb technology in the field of machine tool manufacturing.
From a technical perspective, machine tools achieve precision on extremely small parts by minimizing the forces generated by turning or grinding as the workpiece passes through a sliding headstock and guide bushings . Now developers at a European company are introducing a design element that will further improve the machine's accuracy.
Company executives point out that over the past three decades, the company has been working to minimize heat transfer in its machines . Now, with the use of a new carbon fiber grinding and adjustment roller, the company has solved the last hurdle . Developers claim that by minimizing thermal cycling in the grinding sequence, consistently high-precision production can be guaranteed .
According to the executive, the introduction of carbon fiber spindles fulfills a decades-long development . Their machines have been using linear motors for 30 years. Twenty-five years ago, machine beds made of solid natural granite were adopted; due to their size and inertia, these beds retained very little heat . Later, the grinding roller slide was designed as a granite block, and the vertical stop surface of the spindle further reduced heat transfer.
How carbon fiber materials react to heat has a major impact on precision manufacturing. Carbon fiber has a particularly high temperature resistance. Carbon fiber rollers can therefore prevent thermal expansion of the machine and reduce heat transfer to an absolute minimum . They have greater dimensional stability and increased bending stiffness , which means they can be operated at higher feed rates, which in turn means higher cutting performance . In a series of tests, carbon fiber rollers were 10% to 20% more efficient than steel rollers . Roller made of carbon fiber have several advantages, the first and foremost of which is minimal thermal expansion . Specifically, depending on the type of fiber and the fiber orientation, carbon fiber rollers can be produced with different properties to meet the customer's process requirements.
