Pure water cutting does not require a pool of water common to abrasive configured machines.
Adding Multiple Cut Heads
The standard machine has a single cut head assembly  directly mounted to the primary linear powered carriage car.   Multiple carriages can be added to the gantry Y axis as unpowered or powered.   The unpowered is a slave carriage having a tie rod connection back to the primary powered carriage.  The distance between the primary and slave carriage is then manually adjusted.   Adding a second linear powered carriage allows each to move in sequence with pitch distance between carriages software controlled. Dual powered carriages provide best acceleration for multiple cut head configurations. 

Each carriage has one cut head directly mounted or by adding a mounting plate can accommodate two cut heads per carriage.    PST can assist in reviewing the cut patterns to optimize your cutting needs.  Buyers of multi head machines need understand the distance adjustments between cut heads including cut envelopes for single or multi cut heads.

2 4 2 heads common mount plate / carriage 18" - 60" software controlled
High Gantry Option
The standard table is designed for 8 inch clearance under Gantry.  Therefore operators can stack soft materials for cutting to this max height.  As an option PST offers a high Gantry design yielding maximum clearance at 12 inches under Gantry.  As to not induce cut head vibration this higher Gantry design reduces machine maximum cut speeds and accelerations be roughly 15%.  In combination with this feature the Z Axis motion range can also be increased from 6 inch standard to 12 inches.
Park Zone Option
The optional Park Zone provides a storage location for the secondary carriage when not in use.   Machines designed for multiple cut heads may have times requiring a single cut head travelling the  full tables cut envelope.    This feature eliminates having to remove the secondary car.

The Park Zone adds length to the Gantry to accommodate the second carriage car, therefore must be ordered at time of machine fabrication.
Material Handling Features
Soft materials are commonly sold in sheet form, stacked or as rolled material.  These soft materials are typically light weight, flexible to handle, and in some cases will not lay flat without assistance.  PST offers several material handling options to increase machine productivity.  The ability to cut parts and stage materials greatly increases production capability.
Shuttle Work Bed System - optional
Single or Dual Shuttles Offered

Gantry Material Clamps - optional
Pneumatically clamps grap roll stock then uses Gantry Drive to pull / advance roll stock into the Water jet cut envelope.
Servo Z Axis Software Controlled - optional
A “Servo Z Axis / Float” feature is optional providing software control of the cut head.   The Z movements are programmed within the cut file to accommodate for materials at an angle or changes in heights.
Collision Avoidance - optional
This feature moves the cut head up after completion of each cut part prior to X or Y axis movements.  This avoids possible cut head collision with completed parts that may have tipped after cutting.   This feature is more common for  hard material cutting and only certain cases with soft materials.
Digitizing Camera / Software - Standard Feature
All PST tables are equipped with a digitizing system consisting of software and a cutting head mounted video camera.  This enables one to place a flat irregular pattern on the machine’s cut bed and trace an outline of the pattern yielding a DXF file.  This file can then be input to the Post software to create a cut ready file.  This system is quick and accurate enabling the user to establish cut files from odd shaped templates that would otherwise be difficult and time consuming to draw.   Operator can mount camera and be ready to digitize in less than two minutes.
Remote Pendent Control - Standard Feature
A remote pendant is standard equipment providing the operator bidirectional motion control of the cutting head and gantry positioning.   This hand held controller is ideal during material setup plus control override during cutting routines.
Cutting Head - up and down control ( z-axis )
Independent X and Y control
Simultaneous X and Y control - diagonal movements
