Unique machine concept
Horizontal spindle position

The horizontal spindle position permits the longest possible Z-travel path and optimum chip fall.

Maximum stability

The unique arrangement of the three linear axes minimizes the distance between the guides and the machining point (TCP), lending the machine considerable stability.

Tunnel concept

The tunnel concept allows the largest possible component – even in the case of with extremely long tools – to be swiveled and machined within the work area without collision.

Large swivel range

Three linear and two rotary axes permit 5-sided machining, 5-axis simultaneous interpolation as well as GROB TRAORI turning. With a swivel range of 230 degrees in the A-axis and 360 degrees in the B-axis, these machines offer the greatest possible positioning flexibility.

Machine control panel

GROB4Pilot

GROB4Pilot is your powerful machine control panel. A multi-functional user interface offers the machine operator a convenient working environment. The entire production process – from the CAD model through to the NC simulation – is digitally mapped on the GROB4Pilot control itself. GROB4Pilot is available for the control systems SIEMENS 840D sl and HEIDENHAIN TNC 640.

Features:

 

  • 3D display of parts and their clampings
  • Read out of dimensions or product characteristics (PMI) on the 3D model itself
  • Touch keyboard within the display
  • HTML5-compliant web browser
  • Custom user interfaces
  • Activation of remote maintenance via switch

 

Advantages:​​​​​​​

 

  • Enhanced user comfort with simplified and intuitive machine operation
  • CAD/CAM programming on the machine itself
  • Access to the GROB-NET4Industry platform
  • Extended applications for increased efficiency
  • Paperless production facility
  • Time saving by use of applications parallel to machine operation

Customer-specific automation solution
Customer-specific automation solution

The tougher requirements in the automation sector call for individual solutions tailored to the customer's specific needs. GROB offers such solutions, from customized part handling through to flexible manufacturing lines with multiple machines and centralized tool supply.

Software options

Use the GROB software solutions to optimize and analyze the machine kinematics of the G350T and minimize deviations down to the finest detail.

GROB swivel axis calibration (GSC)
GROB swivel axis calibration (GSC)

For highly precise machine calibration and control-specific kinematic cycles. The GSC achieves a much higher level of accuracy than standard calibration cycles without using swivel cycles.

GROB kinematic measurement inspection equipment set

In addition to the kinematic measuring cycles, all measuring instruments are supplied in an inspection equipment set.

Interpolation turning PLUS
Interpolation turning PLUS

The interpolation turning PLUS software solution enables any turning operations on the G350T. Because both new and standard tools can be used, it remains economical at all times and is the ideal solution for prototype and small series production.

Energy efficiency package
Energy efficiency package

For efficient use of energy by reducing the power consumption of the G350T (with SIEMENS control system).

Gear hobbing
Gear hobbing

For individual corrections and block entry at any cut, gear hobbing is a suitable process for external gearing and gearing on shafts.

Gear skiving
Gear skiving

For perfect external and internal gearing with power skiving machines. Frontal part access required for hob peeling.

GROB TRAORI turning
GROB TRAORI turning

GROB TRAORI turning leads to a dynamic alignment of the tool cutting edge to the contour of the turned part in consideration of tool length and tool radius. Consequently, a significantly longer service life is achieved and short tools can be used.
