IMTS 2016: German Machine Tools of America (GMTA) (N-6924)

Rasoma Machining Centers 

Now available from German Machine Tools of America (GMTA), a full line of Rasoma machining centers, including vertical turning centers, 4-axis shaft turning centers, end machining, double spindle and various special purpose machining centers with full automation is offered. 

Rasoma machining centers offer high rigidity, due to separate X and Z slides plus the machine head is designed as a monoblock with polymer concrete fill. Thermal stability is enhanced by cooled motor spindles and the rapid traverse on these centers ranges up to 60m/min at high acceleration, with feed and removal speeds up to 120 m/min, less than six seconds from part to part and turret indexing typically under one second.

Full option packages include robotic handling and part articulation, integrated metrology onboard, working inside or outside the work envelope, full tool measurement and monitoring systems and driven tool packages, all controlled by a single Siemens CNC.

Samag Machining Centers

Now available from German Machine Tools of America (GMTA), a full line of Samag machining centers, including multi-spindle, horizontal machining centers, deep hole drilling machines and combination milling/drilling machines, is offered for the North American market.

Samag builds a variety of multi-spindle machines, including the MFZ Series for large workpieces, the smaller, modular WBM Series for up to six spindle deep drilling and the combination TFZ Series, which offers users the ability to bore and mill complex cubical workpieces on four sides with a single clamping. On the largest standard machine, large scale moldmaking is possible, with a maximum drilling depth of 2300mm (over 90"), 65mm (over 2-1/2") bore and a 50-ton capacity work table.

The company also supplies complete turnkey operations, including robotic articulation, parts handlers and transfer mechanisms for high-production work such as connecting rods and complete machining of differential housings.

BvL YukonDAK Cleaning System

The BvL cleaning system is the continuous system "YukonDAK". It uses workpiece carriers to transport the goods on a chain conveyor. A light barrier ensures positioning accuracy for the exchange with the automation system.

The system carries out two steps: cleaning through spraying and drying through blowing. The items to be cleaned are crankshaft covers which are produced for a German automobile manufacturer. The parts are washed with a cycle time of 12 seconds and at a temperature between 50 and 55 °C.

The "exhaust air management" developed by BvL reduces the volume of exhaust air which consumes the most energy in a continuous cleaning system. To achieve this, the system measures the moisture content in the drying zone and extracts only as much air from the process as necessary. This creates the best possible moisture level in the system and the volume of hot exhaust air - and therefore energy - blown out of the system is kept as low as possible. The warm and most air and with it the energy remains in the system .Overall the system uses 28 percent less energy - which corresponds to savings of 14.4 kWh - and produces about 5 dB(A) less noise emissions.

In addition to the energy saving measures, the cleaning system is equipped with a 50 μm dual changeover filter, an air-cooled steam condenser and a mist eliminator.
