Quick change pallet system for AM
- September 18, 2019
Schunk has introduced the sealed quick-change VERO-S NSE-AM mini 78-20 pallet system.
The new system is designed to reduce setup times and improve productivity specifically in additive manufacturing. The new module is based on the proven metal-cutting idea of raid setup of machines for laser sintering (SLS) and laser melting (SLM).
At a maximum operating temperature of 200° C it is specifically prepared for systems with active heating. Its compact dimensions (ø 78 mm (3.07 in.), height 20 mm (0.79 in.) above the machine table) ensure an optimal heat flow to the substrate plate, so that after the fast change process the required target temperature for 3D printing is quickly achieved, and production can start as quickly as possible. The module can also be used for works in an inert gas atmosphere – and it can be operated with this gas. The VERO-S NSE AM mini 78-20 can be fully integrated into the machine table and can be combined with further modules.
A uniform interface provides for a continuous process chain. Insertion radii facilitate the loading process. For the use as a single-acting clamping module Schunk has a version with anti-twist protection in their program. A turbo function is integrated by default and the pull-down force per module is 1,500 N. The actual clamping takes place without any external energy supply via spring force and locks form-fit and self-retaining. Even in the case of a sudden pressure drop the substrate or base plates stay safely clamped. The repeat accuracy amounts to < 0.005 mm.
For opening the module, a system pressure of 6 bar is sufficient. Since the interface of the module corresponds to the one of the VERO-S NSE mini 90-25 clamping modules for machine tools, generatively manufactured components including the base plate can be directly changed on the machine tool with the VERO-S NSE mini interface. This means a continuous process chain can be implemented from three-dimensional printing to the machine tool up to the measuring machine.
