QM Systems Q-MAC3  Automatic Variable index system

QM Systems can tailor our Q-MAC range to suit your mechanical and software requirements.

The seat assembly line transfers several variants of seats originating from 3 common base frames. The production line takes the product from a steal frame through to a complete squab. The bespoke fixtures can accommodate all ranges of seats without tooling changes. The fixtures on mounted on the G2 Gimbalator. This provides the customer with 180° of movement once in station to allow the operator to perform a series of dressing, finishing and testing processes.

As certain processes have varying takt times, the system will buffer them accordingly to provide optimum throughput and a balanced line.

The system is made up of 30 station spanning 30 meters with an additional 3 buffer stations.

There is 1600mm between workstations and buffer stations in between that giving a pitch of 800mm.


The system allows our customer to build a series of automotive seats for a variety of high end motor vehicles.

It allows flexibility in build processing to allow our customer to manufacture to line side ordering.

The QMAC-3 achieves this by balancing the the transfer of seats from station to station whilst linking into and MES system providing a no fault forward operator build recipe via an RFID tagging system located on the G2 Gimbalator.

When the seat has completed its build process, it is released from the fixture and manually transferred onto the mating line where the squab is assembled to the seat. The system provides our customer with full flexibility to a variety of build patterns spanning across a series of models.

Product Variants

The range of products spans across a multi vehicle platform. There are there core ranges of seats of which there are 20+ variants within.

Integrated to the pairing line via a MES system. It also is integrated to a variety of external processes such as DC tools for tightening various fasteners all at differing pre-determined limits.

The system has been optimised to run at a set speed but should production requirements change in the future the inverted drive a can run quicker
