BASIC CONFIGURATION OF THE MACHINE

Machine column horizontal-longitudinal  X =  2.000 mm

Spindle stock slide vertical                               Y =  1.300 mm

Spindle headstock horizontal-cross                  Z =  1.300 mm

 

HYBRID FRAME X-AXIS

The hybrid frame is designed as torsion-resistant welded steel construction with mineral filling. Extensive foundation works are unnecessary. Due to the inherently rigid structure the hybrid frame serves as the basis for all other machine components.

 

At the rear of the base frame 3 hardened compact guides in gantry design connect the X axis to the machine column. This kind of construction grants high precision and rigidity during travel and ensures a dynamic and vibration-damped run of the machine column along the X axis.

 

The inner space with all-side steep walls is leading to a central opening. The interface of the machine table is positioned on top and accessible all around. This allows an ideal removal of chips and coolant in the central chip conveyor.

 

CENTRAL CHIP CONVEYOR

The slat-band chain conveyor is located in longitudinal direction (X axis) under the central opening of the hybrid frame. The spacious loading width provides optimum chip and coolant removal.

 

– Loading width               mm    900

– Ejection height              mm    1.140

– Ejection to the left

 

MACHINE STAND Y-AXIS

The column is a distortion-free welded construction. In longitudinal direction (X axis) 3 compact linear guides connect the machine column with the hybrid frame. Two additional linear guides, arranged vertically on the machine column, host the headstock slide with headstock (Y axis). Large-scale guide rail distances grant the transmission of high cutting capacities at a constant quality. A lamella curtain (vertical blinds) protects the column against chips and coolant water in direction of the working area.

 

HEADSTOCK SLIDE AND HEADSTOCK

The head stock slide and the headstock are GGG 60 cast iron constructions. In vertical direction (Y axis) the head stock slide is connected with the machine column by means of 2 compact linear guides.

 

The headstock disposes of two horizontally placed linear guides. Guides with holding strips (keepers) are guiding the headstock in the headstock slide.

 

In order to avoid a tilting of the headstock column, the Y and Z axes are arranged as closely as possible to each other. The large-scale guide rail distances grant highest transmissions of cutting capacities at a constant quality.

 

DRIVE SYSTEM

Digital feed drives for the X-, Y- and Z axes permit working at a high contour precision with constant torque. Feed and rapid feed range.

 

– Feed / rapid feed in all the axes: 2-30.000 mm/min

– Acceleration values in all the axes 2 m/s²

– Drive of the X axis by means of a ball screw Ø80 mm

– Drive of the Y axis by means of a ball screw Ø63 mm

  in connection with an hydraulic counterweight

– Drive of the Z axis  by means of a ball screw Ø63 mm

 

MEASURING SYSTEM

For a precise move of the three main axes, exclusively direct, absolute linear measuring systems of Heidenhain are used.

 

WORKSPACE CLADDING

The work space is completely closed to the outside. Two opposed angled sliding doors with large inspection windows are mounted in front. The large opening width offers an ideal accessibility for loading by crane. Another door with large window for the personnel is mounted on the hybrid frame. It allows the operator to directly view the process and to enter the work space if required. The floor inside the work space consists of a coarse mesh and anti-slip protective grid for best possible chip flow. The rear area in direction machine column is completely closed by means of a lamella curtain/vertical blinds, in which the tool change flap is integrated. Two lights mounted in the roof ensure a good illumination of the work space. An additional light for a good illumination of the operator platform is installed outside on top of the access door.

 

– Opening width of the doors for UniSpeed 2000                 mm     2.240

– Opening width of the doors for UniSpeed 3000                 mm     2.900

 

DESIGN VIEWING WINDOW SAFETY GLASS

The sight window in the front side prismatic sliding door and lateral operator’s access door are executed with safety glass. The side oriented to the working area (glass) offers, compared to screens made of polycarbonate, a  greater durability  against influence due to coolant emulsions and chips.

 

WORKSTATION / COMFORT PACKAGE (RIGHT)

The workstation on the right side offers much more than standard functionality of a platform. It combines ergonomics and functionality – it is a plus for the operator. The bench seat gives him the chance to program at the panel and to monitor the machining process in an ergonomic and comfortable position. For paperwork or minor assembly work he has a workbench at his disposal which offers additional storage space in the lower shelves. Drawings can be fixed at an integrated board – tools find their place in three laterally arranged storage locations. Sockets are available for external units. A Bluetooth radio with USB and speakers is also integrated. Summing up: this unit is a smart working station perfectly suited for the requirements of the operator.

INTEGRATED BALANCING MEASURING DEVICE

By means of a special accelerometer mounted securely at the base of the rotary table, any vibrations found, are registered. An electronic balancing system then informs the operator of the required counterweight, together with the angle and diameter where this weight is needed.  The operator has the possibility to adjust the given data and make further calculations.

 

Balancing quality according to DIN ISO 1940 for machine tool parts and tools: Dependent upon complexity G 6,3 > G3 is possible on the machine.

 

DOUBLE PALLET CHANGER

The Twin Pallet Changer is situated in front of the machine. In connection with a table, equipped with a pallet clamping station (separate position) integrated in the machine, alternatively two pallets (separate position) can be supplied to the machine.

 

Essentially consisting of:

–  Pallet transfer station

–  Shifting table with storage places

– Cover for the loading station

 

The pallet transfer unit bridges the distance between machine table and shifting table and carries out the transport of the pallet. For this the transfer unit is equipped with roller bars on which the pallet, by means of an integrated chain unit and a carrier bolt, is moved.

 

The shifting table has a linear axis arranged in a 90° position to the pallet transfer unit. On this linear axis there are two non-rotating tables with stationary roller bars. The deposit places are provided with a pallet locking mechanism. The linear axis positions the relevant storage place aligned with the pallet transfer unit, in order to start the pallet transfer.

 

The cover of the loading station includes a platform with integrated coolant trip pan which covers the complete area in front of the machine. By means of a pump the collected coolant is returned directly into the chip conveyor. Laterally the platform is surrounded by a fence. For free access to setting work, the front side is provided with a light barrier. In connection with the pallet changer the doors are electrically powered.

SHW UniScan

3D Crash and Vibration overload recognition

SHW UniSc@n provides a real time crash recognition in all axes. This is possible with a 3D acceleration sensor with a reaction time of less than a millisecond. An identified collision leads straight to a machine stop, thus reducing significantly consequential damages. A further function provides warning limits with regard to vibration overload. Potential damages due to excessive use of the machine are prevented.

 

Machine diagnosis:

A further function of the SHW UniSc@n is a machine diagnosis which gives direct indications as to the condition of the machine. Consequently a condition-based maintenance is possible, thus avoiding unexpected downtimes and helping to achieve a higher machine uptime.
