USEDSCM PRATIX 48 NST NESTED BASED MACHINING CENTER:

 

BASE DESIGN AND CONSTRUCTION:

High quality, fast precise machining thanks to:

- monoblock steel base and mobile upright that is normalized to ensure stability,

  increase structural integrity and provide maximum working precision

- prismatic section of the frame with a large support surface to guarantee

  high machine stability and ensure easy cleaning  of the working area

PANEL SUPPORT AREA:

- The multifunction worktable is made completely of aluminum alloy to provide a perfectly flat machining surface over the life of the machine even if there are significant humidity and temperature variations.

- The worktable is directly fixed to the machine base for strength and to prevent vibrations

- Integrated internal piping for the vacuum system

- Along the entire surface there are holes set 120 mm apart for the vacuum and grooves running 40 mm apart for fixing the workpiece using simple rubber seals

- Retractable reference stops controlled by NC for fixed references during workpiece positioning and for the program origin.

MOVEMENT OF OPERATING UNIT:

Maximum working precision thanks to:

- The use of prismatic linear guides and preloaded recirculating ball bearings for the X, Y and Z axes.  These provide higher performance in terms of movement quality and longevity.

- Movement through very high precision recirculating ball screws with

  preloading system with zero backlash for maximum positioning precision.

- Easy and quick movements without any vibrations through the computerized

  control of acceleration by means of digital brushless motors and

- Balancing system for the "Z" axis movement.

OPERATING UNIT:

- Routing unit fitted with a power electrospindle and automatic tool changer.  The unit is fixed directly to the machine mobile upright

- The operating units are complete with a dust extraction system to ensure the

   maximum cleaning of the working area.

- inverter size according to the power of the installed electrospindle

- protection of operating group and devices in conformity with 

  international safety regulations

- pneumatic system and electrical installation in conformity with USA safety

  regulations

Photocells and Protective Cage

Due to the increased speeds of today’s machining centers, the  Pratix 48 NST is equipped with two photocells.  The photocells allow for  safe loading/unloading of the machine.  The sides and rear of the machine are also surrounded by a protective cage to prevent intrusion during operation.
