Machine features
Whether machining simple or complex precision parts – whether 5-axis positioning or 5-axis simultaneous milling – the FEHLMANN VERSA 645 linear excels at any challenging task – precisely and reliably.
The fact that only two axes on the tool side are used for cutting ensures high rigidity and precision and thus a flawless surface finish.
The tilting rotary table is integrated into the machine concept in the longitudinal direction, thus guaranteeing a swivel range that is independent of the linear axes (without kinetic coupling effects).
It is also equipped with direct drives with cooled torque motors and high-precision angle measuring systems, which ensure maximum dynamic accuracy even during simultaneous multi-axis machining.
Features and highlights
The FEHLMANN VERSA 645 linear was designed for maximum precision throughout. Cooled sliding components as well as the cooled machine design constantly prevent unwanted heating.
The X-axis with tilting rotary table is supported over the entire length of the bed for perfect stability. The stable slewing bridge with counterweight also contributes to high rigidity.
Excellent access and optimal overview of the machining area. Manual loading of parts is done from the front. The door extends directly into the machine roof, allowing comfortable loading by crane from above.
The tool changer with chain magazine has a capacity for 50 tools in the basic version and can be upgraded to 86 tools.
The additional rack magazine holds up to 400 additional tools, is scalable and can be easily and economically installed on the left side of the machine.
High rigidity with minimal thermal growth and optimal vibration absorption thanks to the machine base made of gray cast iron with three-point support system.
Perfect dynamic precision thanks to the weight-optimized moving parts made of spheroidal cast iron.
Standardized or even individual automation with a robot can be upgraded at any time, as the right side of the machine remains accessible.
Can also be easily combined with the FEHLMANN VERSA 825 automation system at any time – thanks to the intelligent symmetrical concept, which leaves the right side of the machine accessible for automation.
Perfect control from the front with ergonomic configuration of all controls.
Wide selection of pallet types for individual custom solutions.
Parts Handling - automation without limits
Thanks to its sophisticated and compact design, the FEHLMANN VERSA 645 linear can be automated at any time.
Since the automatic loading door is located on the right side of the machine, an automation system can be easily connected. The processing area has free access from the front for setup and process control work, regardless of the machine configuration.
Depending on the number of pallets and the variety of parts, the system can be operated and monitored by the pallet management system integrated in the control unit or via the flexible FEHLMANN MCM™ (Milling Center Manager).
The FEHLMANN VERSA 645 linear can therefore be adapted to a wide range of automation concepts – even if you decide to upgrade your machine later.
When an 8- or 16-hour shift per day is not enough… Increasingly, “time to market” is one of the most important “survival” criteria for modern tool shops and parts manufacturers.
New products are developed and produced in extremely short periods of time. With the latest information technology FEHLMANN MCM™ (Milling Center Manager), parts can be loaded and unloaded quickly and reliably – in an operator-friendly manner.
In addition to high part quality, key factors are unlimited availability, system availability during day shifts, and process safety during ghost shifts (unattended work, with or without a small number of personnel).
FEHLMANN MCM™ offers you valuable support – proven many times over – that meets modern automation requirements and is based on open industry standards. Since the MCM software is an in-house FEHLMANN development, you can trust us to support the entire system.
Almost limitless possibilities – discover FEHLMANN MCM™!
Fehlmann Milling Center Manager
The milling center control system – an in-house development by Fehlmann – controls the machine and the robot. The machining sequence, zero points, etc. are entered in a simple and clear work table (Windows interface).
With a click of the mouse, the operator can change the machining sequence or individual parameters while the system is running.
Maintaining flexibility even in automatic mode: the part can be set up without any problems. Thanks to the high operator comfort of the machine and the MCM, the Fehlmann solution is not only suitable for series production, but is already effective when only a few parts are manufactured.
Tool breakage monitoring, CNC program control, system event logging and telephone alarm (optional) via SMS sent to a pre-selected mobile phone number are just a few of the functions that allow unattended operation at night or on weekends.
Complete system from a single source
The systems are commissioned and tested with a configuration that meets the customer’s needs here in our workshop.
We develop and manufacture the machine and the MCM™.
We use standard robots for the processing of the parts.
With the above systems, we offer proven solutions.
We owe the practicality of our solutions to a large extent to the many suggestions and ideas of MCM™ customers, many of which have been used in the standard solution.
Options
Our machines are already equipped with all the functions required for high-precision machining.
Various options are available, such as:
- High-pressure coolant system with spindle feed and chip conveyor.
- Various tools and part measuring systems (probe systems, laser …)
- Integrated minimum lubrication for HSC machining
- Integrated zero-point clamping system and automation solutions
