Techno machines come standard with a multi-zone, high flow, phenolic vacuum T-slot table.  The table includes electro-pneumatic valves to control the zones.  The table is ported throughout the full process area, thus allowing the air to move evenly under the MDF scavenger board.   This ensures a superior vacuum hold down.  The T-slots add additional mechanical clamping capability when vacuum hold down is not suitable for the particular part you may want to process.  This design gives companies the maximum flexibility.
