The benefits at a glance

High productivity

Optimized availability

High visibility

Flexible applications

Maintainable

Compact design

Optimized access

Round-the-clock service

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.

Pure technology in the smallest space

Disk-type tool magazine

Fast tool change through an intelligent magazine to motorized spindle arrangement

Horizontal motorized spindle

For meeting the toughest cutting requirements

Mill-turn table

Almost limitless machining potentials thanks to the largest possible swivel range

Chip disposal

Uninterrupted part machining with chip disposal by a slat band conveyor

Machine bed

Intrinsically stiff welded design for optimum machine rigidity

Machine control panel

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

Automation solutions

Draw on the experience we have garnered over several decades and benefit from the automation technology we tailor to meet your needs – from solutions with part storage systems to highly flexible manufacturing lines.

Rotary pallet storage system

Optimized view into the work area and towards the pallet storage positions
Parallel loading and unloading of the pallets during the machining operation
High storage capacity with small footprint
Pallet storage solution for small initial investment
Simple retrofit on existing machines

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)

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

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

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

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

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

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.
