SPECIAL FEATURES
One piece construction is superior to our competitor's 2 piece. Our design uses a splined pinion shaft which is much stronger and more rigid than the keyed shaft. Our standard spring type micrometer adjusting nut provides quick and easy movement for setting spindle depth.
Gaskets are used to prevent grease and oil leakage. One pieces quill housing ensures precise alignment, eliminates vibration, and prevents premature bearing failure. Dynamically balanced pulley with special bronze key attached with 2 screws prevents premature breakage.
Our special power down feed parts are so strong, they can be used over 3,000 RPM spindle speeds. Our 1 piece cluster gear is superior to the much used 3 piece design. The splined shaft is much stronger and provides greater safety than the keyed shaft. Willis 3HP inverter drive milling head - EV.

Powerful Conversational CNC retrofit System for Knee & Bed Mills

Boosting Productivity is Now Poweful Easy

Faster set-ups, shorter run times and a major boost in productivity are just one "powerful easy" retrofit away. The new ACU-RITE MILLPWRG2 control and retrofit kits can turn just about any knee mill into a powerhouse money-maker.

USB and Ethernet compatible, the new G2 features a bright 12.1" high resolution display, 1 GHz processor
and plenty of programming capabilities - estimated runtimes, expanded tool/datum offsets. enhanced tool paths, a dxf converter - plus much. much more.

The MILLPWRG2 is a contouring control that enables you to program conventional machining operations
right at the machine in an easy-to-use conversational programming language. It is designed for both knee mills and bed mills with up to 3 (three) axes.

MILLPWRG2 was developed specifically for machinists where manual and automated operation are both useful and needed. It's designed to maximize throughput by significantly reducing set-up time, scrap, and
other non-productive operations. thereby increasing your efficiency, productivity and profitability.

A closed-looped system with positioning feedback provided by ACU-RITE precision linear encoders (lµm/0.00005" resolution). MILLPWRG2 also includes Position-Trac™. an advanced, unique feature that enables you to easily, quickly and accurately re-establish work piece zero after shutting down, or power loss.



Easy-to-Master Programming Improves Efficiency, Profitability

Standardized menus make it easy to program common features like lines, arcs, custom pockets, bolt hole patterns, and islands. To add a feature to your program, simply press a function key and then follow the prompts. MILLPWRG2 also includes an "engrave" option for engraving alphanumeric characters vertically, horizontally, diagonally or along an arc.

Common machining features are now as simple as press and go.



USB CONNECTIVITY - FRONT & BACK
Loading and off-loading programs, importing data via USB is now a plug-and-play convenience, with USB ports located on both the front and the back of the new G2 control.





3D Graphic System Improves Programming Efficiency & Accuracy

Intuitive navigation menus eliminate the need for multiple screens.

Programming cycles use a simple, easy-to-understand set of machinist language prompts, accompanied by content­specific "help" graphics. Here is a step-by-step look at the new G2 graphical interface. as a simple bolt hole circle and pocket are entered:

Fagor CNC 8055
With the User in Mind - More Powerful Than Ever

Fagor Automation has been providing Automation solutions to the Machine Tool market for over 30 years with the emphasis on large batch production, small production runs and prototype applications which requires a versatile, yet powerful CNC solution.

The 8055 CNC provides perfect solution to both types of machining as it offers ISO G-code language highly suitable for high speed production based machining and the intuitive ICON key conversational programming language for small series or unitary work pieces where programming/set-up time is a crucial factor in determining the productivity of the machine.

The flexibility of 8055 CNC allows the possibility to combine both of these programming methods, thus increasing operator efficiency in addition to providing him with expanded capabilities.


Fagor Automation has engineered and produced it’s CNC, Servo & Feedback products to work together as a unified system thus providing optimum performance and ease of operation.

When utilizing multiple different brands within a system, integrating them together in reliable harmony becomes cumbersome and often complicated.

Fagor Automation allows the integrators to have a single source for all vital Automation components with the confidence that all of these products have been designed & engineered with the direct intent of optimum performance, efficiency and reliability, thus greatly simplifying the Integration process.



Machining - High Speed Machining

During high speed machining operations, the 8055 CNC is in control of assuring smooth & accurate tool path without sudden accelerations or decelerations in order to obtain the most stable machining speed possible, thus avoiding part surface irregularities.

Easier Machine Set-Up
Graphically assisted set-up user interfaces, such as the oscilloscope function mode or the geometry test help ensure the CNC makes up for the possible lack of performance of the mechanical system by considering the particular dynamics of the machine.

Operation With the User in Mind

The ICON based operations of the 8055 has been specifically designed for operators of conventional machines who lack prior programming knowledge such as ISO G-code language.

Preparation Help

Tool Management
Tools are managed before and during machining through simple intuitive operations that make the operator’s job easier.

Part Preparation
In serialized part production, in order to obtain repeatability in the positioning process of the new parts, the 8055 CNC helps the user run these operations fast, accurately and efficiently.
