    Designed to accurately control thickness and parallelism of thin and delicate parts during lapping and polishing operations, the Hyprez WTD is capable of accepting a variety of product configurations. In addition, it can be used in conjunction with a parts carrier to process multiple parts in a single cycle resulting in decreased manufacturing costs.

    Key Features
    •  A vacuum chuck with a hardened steel support ring and digital indicator to monitor part thickness.
    •  A powerful vacuum system featuring a dial gauge to monitor pressure along with a quick-connect for fast changeovers, maximizing ease of operation.
    •  In addition, the free weight platform can be used as a device stand.

    Robust and durable, the WTD is portable and easy to use. Upon request, Engis can provide wear resistant contact surfaces or customized sub-fixtures to accommodate your specific parts handling requirements.
