Twin-spindle HMCs increase productivity
In production machining projects, the use of twin-independent spindle horizontal machining centres can reduce the total of machining centrres required by 30-40%.
EMO 2005 saw the world launch of the Mach 1-500 Syncro, designed and built by Honsberg Sonderwerkzeugmaschinen in Remscheid, Germany The new Mach 1-500 Syncro, a consistent further development of the proven Mach-1 concept, is a dual spindle horizontal machining centre which basically combines 2 single-spindle machining centres in one machine

Spring maker diversifies into CNC machining
The foresight to move into new products and new markets, based on acquisition of machining centres, has ensured the continued growth of a former spring maker.
Customised CNC with wizard screens used in VMCs
A customised CNC is believed the most user-friendly, reliable and highly specified CNC on the market, and is available with a range vertical machining centres.
The machine, designed for simultaneous machining of two parts, is equipped with two independent spindles and tables, with 2 linear axes in the spindle and one linear axis in the table.
The large spindle spacing enables synchronous machining of large workpieces.
A special feature is the individual compensation of all NC axes in real time, guaranteeing precise and fast machining of workpieces with tight tolerances.

VMCs can be tailored for specific purposes
New cast iron structure features a range of vertical machining centres, available in four model designations and three performance packages, to tailor machines to different applications.
Five-axis VMCs feature high precision tilt head
A range of 5-axis fixed table VMCs has a high precision spindle head that features up to +/-95 deg tilt in the A-axis and full 360 deg contouring in the C-axis - ideal for machining complex parts.
VMC offers full 5-axis/5-sides machining
Vertical machining centre with a 5-axis rotary table comfortably machines workpieces up to 400mm in diameter and 300mm high, and has up to 150 deg tilt capability.
This also reduces the cycle time compared to DUO machines with shared X and Y axes.
With these features, the Mach 1-500 Syncro fully satisfies customer requirements in terms of productivity, flexibility and high quality.
Thanks to the machine's unique construction and functioning, its installation area is considerably smaller than that of single-spindle manufacturing systems.
Project calculations have shown that the number of Syncro's required is 30 to 40% lower than that of single-spindle machines.
The three linear axes with their rapid traverse rates of 60m/min also offer excellent acceleration of 1G.
The standard Syncro version is equipped with a motorized spindle with 16,000 rpm.
As an option, high-torque motorised spindles with a speed range up to 10,000 rev/min as well as rapid spindles with up to 24,000 rev/min are available, ensuring a high cutting capacity and maximum flexibility.
All spindles come equipped with temperature monitoring and internal cooling.
The two NC rotary tables can manage pallets of 500mm x 630mm diameter and fixture sizes of up to 800mm height and 710mm diameter.
The machine's common double-H type pallet changer can perform a simultaneous change of all four pallets for both machining positions in only 10s.
Machine loading, carried out during the machining time, can be both manual through the operator and automatic with different loading concepts.
This makes the machine suitable for both stand-alone solutions and flexible manufacturing centres.
Each spindle of the Mach 1-500 Syncro has its own, laterally arranged tool magazine which can accommodate 33 tools as a standard with a maximum weight of 15kg.
Magazines with 44 pockets are available as an option.
Tool change time is less than 1s (cut-to-cut time 3s).
Ergonomic ground-level loading eliminates the need for tool lifts or platforms.
Ease of operation and maintenance is our top priority.
All operation and maintenance elements are therefore easily accessible and clearly laid out, guaranteeing fast and easy access for all maintenance tasks to be handled.
Special features are the decentralised fluid installation with valve terminals located close to the consumers as well as the reduced hydraulic system due to the electromechanical design of pallet and tool changer.
Swarf is evacuated by a transverse conveyor integrated into the machine base and running parallel to the X-axis, followed by a longitudinal conveyor inside the machine guard for transporting the chips towards the rear side of the machine.
This contributes to the low space requirement of the machine.
Other concepts can be realised as an option, e g, direct swarf discharge from the transverse conveyor into a flushing channel provided by the customer or a backpump station.
The sturdy design forms the basis for the machine's high-speed capacity and stability.
The machine base is of single-piece compact design.
The Mach 1-500 Syncro is equipped with a powerful Siemens Sinumerik 840 D control with the control panel integrated into the control cabinet.
All essential operator functions can also be carried out by remote control.
The machine is driven by a Simodrive 611D with 1FT6 servomotors.
As the machine can be transported as one unit, transport and installation costs are considerably reduced.
Thanks to the three-point levelling system, commissioning time at the customer's site is shortened significantly.
With its combination of proven elements and new concept features, the Mach 1-500 Syncro offers outstanding flexibility, maximum productivity, highest quality and precision as well as user-friendly operation, while at the same time providing an excellent cost-effectiveness.
