CNC front-loaded turning machine HEYNUMAT FD 180-1-2 with BTS tooling system Block Tool System. CNC front-loaded turning machine with twin spindles driven independently of each other and two slides version. This version has the advantage of permitting sequential machining of a chuck-held workpiece, simultaneous machining of two workpieces, and turning of two different workpieces.

Easy operation and maintenance - friendly environment In the development of new machine tools, the fact that users expect more operating convenience has led to a situation where the machine peripherals are given appropriate attention even at the fundamental DIN machining, basic adaptors for flexible tooling systems and/or drilling/milling heads. This is a trend which has been consistently followed in the FD range. Apart from the primary functions such as high productivity, accuracy, and reliability, ergonomics are also an important factor.

Total enclosure of the machine provides safety far beyond existing regulations. Guarding doors with armored glass windows on both sides feature double-panel construction and slide into the side enclosures. After opening the doors, there is thus no nuisance effect through dripping coolant. The danger zone of the loading system is protected by Perspex windows. Workpieces are always made available in a second plane above the enclosed working area. For the actual changing sequence, a loading door automatically opens/closes during the loading cycle. The sliding control panel contains all instruments and controls required for headstock, slide, CNC, and supplementary equipment such as loading system, workpiece/tool gauging, chip conveyor, etc. A noise suppression hood over the main drive and headstock ensures that noise levels stay within acceptable limits. However, numerous doors provide ready access to mechanism, hydraulics, and electrics of the machine.

2 or 4-axis machining on twin and multi-spindle machines. CNC front-loaded turning machine with two spindles and four slides. This HEYNUMAT FD 250-2-4 with automatic loading system LF-5-2-2. The workpiece is transported by a chain conveyor above the held workpieces. The utilization of two slides for each spindle leads to a reduction of idle and cutting time. A common loading and transfer system station brings the workpieces into position as loaded into the chuck.

Heynumat FD with taiistock for machining short shaft-type workpieces By simultaneously applying two slides and equipping the machine with a stationary tailstock, unusually economical machining of short shaft-type workpieces becomes possible. The disposition of the two slides opposite each other also permits simultaneous parallel machining without any collision risk. Unrestricted chip disposal and the employment of automatic conveyor systems make certain that chips are removed rapidly. The workpiece is supported by a stationary tailstock with hydraulic quill movement. Tailstock thrust can be set in infinitely variable increments. The clamping action is controlled by a pressure and traverse monitor. Quill retraction while the main spindle is running is prevented by safety interlocks.

The LF loading system is a free- standing longitudinal gantry of double beam configuration. To- gether with the newly developed front-loaded turning machine, the loader provides a compact unit not only in design terms but also in its functions. The loading carriage has one or two swivel arms and travels above the working zone, headstock and main drive parallel to the ma- chine Z axis. Each swivel arm has a swivel unit in turn carrying one each gripper for blank and finished part. Starting at the meeting point of work- piece transfer and loading system, the loading carriage travels above the enclosed working area into a waiting position. A loading door auto- matically opens for the changing cycle. Subsequently, the swivel arm plunges into the working area. When the swivel unit has completed the changing sequence, the loading carriage returns the machined work- piece to the transfer system. The standard version is capable of handling workpiece weights up to 15 kg. The loading carriage is driven by electric motor also NC-control- led and cogged belt. Swivel arm and swivel unit are hydraulically actuated. The gripper heads can be individually adapted to any particu- lar application. Simultaneous loading/unloading of two spindles. Guarding doors open. 10 Automatic tool and workpiece handling Loading system LFS The LFS loading system is also a free-standing longitudinal gantry with double girders designed for front-loaded turning machines but also suitable for other machine tools such as grinding machines . In contrast with the LF loading sys- tem, the bogie has no swivel arms and features, instead, one or two vertical loading arm depending on the machine version. Each vertical ram carries a swivel unit with one each gripper for blank and finished part. In addition, each ram can accommodate a tool changer. In this way it is possible to change the tool heads external, internal machining, driven tools of flexible tooling systems automatically see page 12 . However, this requires that the two axes travel to different posit- ions. For this reason, the bogie Z axis is driven by cogged belt and the vertical ram under numerical control by recirculating ball screw. Equipping this system with NC drives also provides for economical loading of machines carrying out the complete machining of parts families.
