In response to demand from the medical device manufacturing sector, Kistler has developed a new, compact version of its NCFT joining module with the stroke length increased to 250mm and the overall length reduced to 482mm.
This has been achieved by moving the drive motor from the end of the module to the side. In all other regards, the new compact version retains all the capability of the original, straight version. Both types consist of a robust housing with a piezoelectric tension/compression force sensor and an absolute encoder integrated in the drive motor for precise positioning.
The compact mechanism, integral piezoelectric force monitoring in the spindle and two predefined measuring ranges from 0.05 kN to 1.5 kN, make both the straight and angular modules ideal for use in assembly and joining processes monitored by force-vs-displacement. The new version delivers complex drive profiles with a maximum speed of 400 mm/s and displacement repeatability of better than 0.01 mm combined with easy selection of the ideal measuring range, high overload factor and modest user spare parts inventory.
Both Type 2157B servo press modules provide ultra-high precision measurement of extremely small forces directly on the tool holder under actual process conditions, without the need to additionally mount a sensor on the drive spindle. This eliminates any possibility of the measurement signal being impaired by dynamic characteristics of masses or moving cables.
Both versions of the NCFT joining module are certified for ISO 14644-1 Class 8 cleanroom use with Class 7 available as an option. As well as medical technology product testing and production, such as inhaler or diabetic pen assembly in automatic production systems or manual workstations, the joining modules are suited to other precision manufacturing applications.
Every NCFT joining system installed will save 2,000kg of CO2 per year and lower the total cost of ownership (TCO) by 90% compared with hydraulic and pneumatic systems.
