  • Rebuilt X-Y Table
  • Refurbished Optics

PTR 60 kV CNC EB Welder

This EBW 700 is a PTR-Precision Technologies 60 kV machine originally built in 1992. It is a 96" x 192" palletized EBW system that has the unique capability of both horizontal and vertical column mounting positions. This unit is not in fully operational condition, some level of modification will be required to start production welding.

CHAMBER SIZE:

43.3" Long x 29.5" Wide X 35.4" High (with Chamber Extensions available)

POWER SUPPLY:

7.5 kW output (60 kV at 125 mA maximum). Solid State SCR Controller for controlling high voltage. 

SYSTEM CONTROL:

*Allen Bradley CNC (*to be retrofitted with Fanuc CNC)

BEAM CURRENT CONTROL:

Solid State Beam Current Regulator (Closed Loop)

BEAM DEFLECTION:

Manual X and Y D.C. Offset plus a Digital Deflection Generator. Amplitude, frequency, pattern (16 available) and pattern rotation are controlled by the CNC or manually.

X-Y WORK TABLE:

Variable Speed D.C. servo motor driven ball screw actuator for each axis.

TABLE RUNOUT SYSTEM:

Powered by X-axis drive

PTR 150 kV CNC EB Welding System - No Longer Available

This electron beam welding system was built in 1987 and operated by PTR's job shop department. Some features include a diffusion pumping system, IKE fast beam current control, nude filament illuminator, manual sliding door on both ends of the chamber, high resolution eyepiece optics and X, Y, & rotary axes electronic handwheels for precise positioning of the workpiece.

The system is in running condition and is available as-is or we can modify it for your specific part and process requirements.

CHAMBER SIZE:

52" Long x 36" Wide x 40" High

POWER SUPPLY:

15 kW high voltage power supply with SCR control of primary voltage. 

SYSTEM CONTROL:

Allen-Bradley Series 8200 CNC for control of X, Y, tilt and rotary axes and beam current and focus current beam parameters.

BEAM DEFLECTION:

Digital deflection generator programmable by the CNC.

X-Y WORK TABLE:

CNC controlled precision X and Y table assembly 25.5" long by 17" wide with strokes of 23.5" in the X-axis and 16" in the Y-axis. This table is capable of supporting 500 pounds.

TABLE RUNOUT SYSTEM:

Manually operated runout capability with platform on the right side of the chamber.
