5-axis simultaneous machining
The 5-axis simultaneous machining on a 5-axis machining centre enables highly precise and highly efficient machining of complex cubic workpieces in only one clamping.
Blasting pistols are used to clean workpieces by blowing with compressed air outside the workspace of a machining centre. They also enable a precise cleaning of workpieces and clamping devices of the entire workspace. The blasting pistols are fed via the compressed air connection of the machine. At the HEDELIUS machining centres, the blasting pistols are located outside the workspace to prevent contamination by chips or coolant and to enable the use of additional devices such as deburring tools or pneumatic screwdrivers.
CELOX-integral motor spindle
CELOX-integral motor spindles are special water-cooled motor spindles, powerful and high-torque, with hybrid bearing technology. This special motor spindle ensures thermostable precision in the HEDELIUS machining centres.
CNC is an abbreviation for Computerized Numerical Control. CNC is an electronic method to control or regulate machine tools, which are also often referred to as CNC machines for this reason. There are various CNC control systems from different suppliers. Here you will find information on the CNC control systems used in HEDELIUS machining centres.
The cutting edge of the rotating tool moves counter to the feed direction of the workpiece in the contact area in this procedure and forms a chip which thickens from the entry point to the exit point of the cutter.
The machining process of drilling is used for realising holes in workpieces. Depending on the depth of the drilling and the diameter of the drill, chips must be flushed out of the borehole using compressed air or coolant. HEDELIUS machining centres therefore have a compressed air nozzle at the spindle head and external coolant supply. Additionally, they can be equipped with an internal supply of compressed air and coolant through the spindle.
Feed speed refers to the speed of the tool for milling the material in the feed direction. HEDELIUS has developed an innovative feed technology to substantially enhance the performance of the moving column machining centres: the FORMINGSTAR® 3D feed technology. High-end servo motors with obliquely grooved ring magnets, in combination with liquid-cooled CELOX® motor spindles, ensure even quieter running.
The full enclosure is a a hood which covers the top part of the machine to provide a totally enclosed workspace. Thus, chips and oil mist are prevented from getting out of the machine during work. For unrestricted crane loading the full enclosure is equipped with a roller-shutter door. Full enclosure is available for the HEDELIUS C, BC and RotaSwing machining centres ranges.
The hand wheel is an electronic aid to facilitate direct work on the workpiece. By moving the hand wheel, the axis carriages of a machining centre are moved.
Heavy-duty machining means large, heavy workpieces made of solid and highly resistant materials such as cast iron, steel and various steel alloys. An efficient heavy machining makes special demands on the machining centre: machine tables with extremely high load capacity, high torque main spindles for high feed speeds (high-speed milling). HEDELIUS offers with the BC series innovative machining centres which meet all requirements of heavy-duty machining.
The high feed milling is a special milling strategy for machining tasks with very high removal rates. The result is a high cutting performance with low energy consumption. With special high-feed milling tools, the time of roughing can be reduced significantly even in the case of hard workpieces and the service life of the tool can be increased.
High-speed cutting (HSC)
High-speed cutting is performed with extremely high tool speeds and feed rates, which means that material is quickly removed, with low chip thickness. In tool and mould-making this cutting method is mainly used for pre-finishing and finishing.
The term “machine tool” refers in principle to all machines which machine workpieces by using tools such as drilling or milling heads. CNC machine tools are used, for example, for metal processing in mechanical engineering, tool making and vehicle construction. In order to ensure a quick tool change with simultaneously high accuracy, the tool holders are standardised.
A machining centre is a CNC controlled machine tool which allows the complete machining of workpieces without repeated clamping. This has the advantage that accuracy is improved and at the same time unnecessary and cost-intensive set-up are eliminated. For automated operation, a machining centre can be equipped with with peripheral devices as for example a pallet changer. Here you will find the HEDELIUS machining centres.
The term manufacturing centre is sometimes used as a synonym for machining centre.
Milling is a machining process. Workpieces are manufactured by removing material, using tools with geometrically determined cutting edges. The tool performs a circular cutting movement at any feed movement. The HEDELIUS milling machines of the Tiltenta range can achieve feed rates of 40 m/min in the X, Y and Z axes as well as a cutting performance of up to 550 cm³/min in steel materials.
A milling machine, commonly also called “cutter”, is the generic term for a large number of different cutting tool machines. This also includes the machining centres produced by HEDELIUS.
Moving column design
A moving column machining centre is a machining centre with a fixed work table and a moving column that performs all axis movements.
NC rotary table
In the generous workspaces of the HEDELIUS machining centres, an NC rotary table for 4-sided machining can be integrated. The NC-rotary table has a vertical rotation axis around which the table with the workpiece rotates. That is, machining of various positions needs only one clamping.
A pallet changer is a module for the automation of machining centres. The pallet changer changes the workpiece pallets in the workspace of a CNC machine tool automatically. One pallet is machined in the workspace, while on other pallets tool changing or clamping work can be carried out. The unproductive downtime is reduced significantly. The ACURA 65 EL by HEDELIUS can be equipped with a pallet changer.
In order to keep unit labour costs as low as possible, there is a further rationalisation potential in addition to five-axis machining which reduces frequent re-clamping. By means of parallel work (clamping and setting) using pendulum operation or a pallet changer in combination with a large tool magazine, throughput times can be reduced.
By inserting a workspace partition wall into a HEDELIUS machining centre with an X-Travel > 1,500 mm, two separate workspaces are created. In the one workspace a workpiece is being machined, while the next workpiece is already being clamped in the other workspace. By machining in pendulum operation, unproductive times are minimised and spindle run time is enhanced considerably. Thus much more workpieces can be manufactured in a shorter period of time.
Pick-up magazines are additional magazines for large tools or angled milling heads. HEDELIUS machining centres can be equipped with a pick-up magazine with a moving carrier plate. Flexibility in machining is increased, tool changing times are reduced.
Pivotable-spindle machining centre
A pivotable-spindle machining centre is a five-axis machining centre with an infinitely pivotable main spindle (B axis). Here you will find the pivotable-spindle machining centres of the Tiltenta range. They machine long and heavy workpieces as perfectly as cubic workpieces.
A rotary/tilt table enables efficient 5-sided machining of a workpiece. On rotary/tilt table integrated in a machining centre even complex cubic workpieces can be machined in a maximum of two clampings.
The semi-gantry design with its heavy-duty overhead roller guides on the Y-axis, which was developed by HEDELIUS, is the perfect design for vertical machining centres. The short flux and the solid machine bed guarantee perfect milling results. The semi-gantry design is the basis of the machining centres of the C, BC and RotaSwing ranges by HEDELIUS.
A standby magazine is a great tool magazine which can be provided in addition to the tool magazine of the machine. The magazine is connected to the main magazine of the machining centre. The HEDELIUS standby magazines can include up to 190 additional tools and transfer them fully automatically to the main magazine of the machining centre. Manual search and tooling times are avoided nearly completely.
The cutting edge of the rotating tool in the contact area moves in the direction of the vector of the workpiece feed direction.
Using a threaded drill, an inner thread is cut into a drilling. HEDELIUS machining centres are able to drill threads without the use of length compensation chucks.
The trochoidal milling the tool uses a circular feed movement. The cutter immerses deeply into the workpiece. The milling paths overlap in elliptic circles. This milling strategy is often used to cut slots or trim edges.
Workspace partition wall
Through the use of a workspace partition wall, one workspace can be turned into two separate workspaces for efficient machining in pendulum operation. Most HEDELIUS machining centres can be equipped with such a workspace partition wall. It takes only a few minutes to insert or remove it in order to change from pendulum operation to the machining of longer workpieces.
Zero-point clamping system
With a zero-point clamping system can be the idle time of a CNC machining centre can be reduced significantly. A zero-point clamping system fixes the workpieces to be machined on the machine table in a few seconds. This is particularly useful when different workpieces are machined one after the other. While the first workpiece is being cut, further workpieces can be clamped outside the machining centre and then placed in the machine in no time at all.
