Guhring modules 6x6 and 4x4• quick and simple setting for perfect concentricity• cooling lubrication delivery without loss and turbulence• optimal for MQL and conventional cooling lubrication

Guhring modules

Spot-on tool setting
Whilst Module 4x4 is the market compatible solution the
Guhring Module 6x6 is providing further opportunities formodular technology to satisfy the highest demands. On
Guhring’s Module 6x6 the setting screws for radial andaxial setting sit much closer to each other than on conventional modules. This allows the elimination of errors inclose proximity to the measuring point – even with 6-fluted
tools with pinpoint accuracy!

Guhring modules 6x6 and 4x4 are the perfect solution fora quick, simple and µ-accurate setting of tools in highly
precise manufacturing areas such as fine machining.
The advantages for the user:• up to 70% time saving in tool pre-setting• cost reduction• highly accurate, wobble-free tool setting• an extremely solid and rigid connection• cooling lubricant delivery without loss orflow disruption

1

Length setting screw with axial force damping
For conventional cooling lubrication the new length setting
screw with axial force damping can be applied in both
modules. It ensures accurate, tension-free shrink fittingby preventing the tool shank deflecting through the axialpressure on the setting screw. It also ensures a perfectlength setting of the tool.

cutting edge. It is in alignment with the first setting screws
for the radial and axial setting of the module. This enables

holder-module-tool system.

Setting screws
Whilst the market-compatible module 4x4 possesses 4 setting screws
each for the axial and radial setting, the respective 6 setting screws of
the module 6x6, thanks to being positioned closer together, provide
an even more precise setting of the module relative to the cuttingedges of the tool. They enable a quick, simple and highly accurate
concentricity adjustment. Setting to 2 µm can be achieved with a timesaving of up to 70%.
The marking of the setting screws from 1 to 6 or 4 respectively simplifies the orientation of the first tool cutting edge in consideration of
the positioning bore.

4

Location bore for balancing screw
The module 6x6 as well as the module 4x4 possess 6 balancing bores.
Thanks to being close to each other they enable a quick balancing inclose proximity of the imbalance. The positioning of the balancing
bores having a large effective diameter and thread depth provides ahighly effective balancing capability.

Modules3Guhring modules

Optimal cooling lubricant delivery
The modules 6x6 and 4x4 have both been designed forconventional cooling lubrication as well as minimal quantity lubrication. Whatever type of cooling lubrication theuser decides on, the delivery system components requiredare 100% compatible. Subsequently, it is possible to convert any modules in stock without a problem.

Delivery unit
The delivery unit feeds the cooling lubricant through thetool holder without dead areas. For this, it is fitted withan O-ring and a special sealing lip. Particularly with MQL
machining, a loss-free coolant delivery in this area isdecisive for an optimal delivery to the cutting edges.

MQL coolant delivery set,
Guhring no. 4939 or 4940
A loss-free cooling lubricant delivery between spindle andtool holder is provided by MQL coolant delivery sets 4939
for automatic and 4940 for manual tool change.
Coolant delivery set for conventional cooling lubrication,
Guhring no. 4949
Alternatively, for conventional cooling lubrication the coolant delivery set 4949 is applied, that is 100% compatible
with MQL coolant delivery sets.

Guhring modules

MQL without loss
Particularly with minimal quantity lubrication (MQL) the
loss- and flow disruption-free delivery of minimal coolinglubrication quantities to the cutting edge of the tool is ofvital importance for an optimum and reliable machining
process.

Guhring’s delivery system: MQL length setting screw and intermediate sleeve
The cooling lubricant is supplied in a straight line without restriction or turbulence from the machine through the tool
holder to the cutting edge. Guhring‘s delivery system can also be retro-fitted to other tool holders!

ModulesGuhring modules

Loss-free conventional cooling lubricant delivery
The benefits of Guhring‘s Modules are not only the quick,simple and highly-accurate tool setting. But the optimalcooling lubricant delivery without restriction or turbulence

ensures a perfect machining result thanks to loss-free cooling and lubrication of the tool‘s cutting edges.

Guhring’s delivery system for conventional cooling lubrication with intermediate sleeve
The cooling lubricant is supplied in a straight line without restriction or turbulence from the machine through the tool
holder to the cutting edge.

Market conventional configuration without delivery system
The cooling lubricant deflects in the tool holder and the coolant exits into and from hollow areas in the holder. In addition, the cooling lubricant exerts force on the piston surfaces due to the high pressure of ≈ 80 bar resulting in hydraulictension and concentricity errors.

p ≈ 80 bar

Guhring modules

Module 6x6 - the advantages at a glance• quick and targeted µ-accurate setting thanks to theclose proximity of axial and radial setting screws to theerror measuring point. Ideal for 6-fluted tools with aperfect fit to the cutting edge.
• quick and targeted balancing thanks to 6 deepbalancing bores and threads providing a high balancing
capacity.
• optimal setting results with multi-flute PCD/CBN finemachining tools or Guhring’s HR 500 high performancereamer with 6 cutting edges.
• especially rigid connection thanks to 6 fastening
screws.
• accurate wobble setting and optimal rigidity thanks to ahigh pre-clamping torque.
• minimal ‘settlement behaviour’ offering highest
accuracy over a long application period.
• universal and modular designed system with hydraulicchucks, shrink fit chucks or HPC clamping chucks as wellas HSK or SK interface.
• available in combination with monolithic special tools.

Perfect fit:
With module 6x6 the error measuring pointis a max. 30º away from the next positioning
bore. The same applies to the balancing
bore.

Setting and handling instructions
GM 300 module 6x6 and 4x4
1. Assembly and radial alignment of module flange
1.1 Clean spigot diameter and plane faces of module flange and alignment adapter.

1.2 Insert module flange

Sealing lip
Intermediate tube
incl. O-ring and sealing lip
TiN-coatedInsert intermediate tube into themodule flange bore up to the shoulder

1) Lightly lubricate the sealing lip2) Carefully insert the sealing lip in centre oflocation bore in order to prevent damage.
Then fit the module flange into thealignment adaptor.

1.3 Tighten the fastening screws to 50 % of the specified tightening torque (see “tightening torque” table)

1.4 Position dial gauge at the concentricity check point (ground module collar diameter). Record highest measuring pointand “zero” the dial gauge.

1.5 Roughly align module flange (approx. 0.01 mm). Loosen the adjustment screws again following procedure.
1.6 Tighten fastening screws to specified torque. Then set the concentricity with the adjustment screws then loosen theadjustment screws again following procedure. Repeat the procedure until the concentricity error is ≤3 µm. When theconcentricity has been adjusted lightly tighten all the adjustment screws and check the concentricity again.

Angular alignment of module flange

2.1 For the angular alignment the dial gauge is positioned at the front concentricity check point, at the cutting edge
guiding pads or at a suitable position. Use the alignment screws to perform the angular alignment. Following theabove procedure do not loosen the alignment screws.
2.2 When the angle alignment is adjusted to ≤3 µm, check the radial alignment at the concentricity check point on themodule collar again and correct if necessary. If the radial alignment has to be corrected, the angle alignment will haveto be checked again.
