DISKUS DDS-L

Small – flexible – precise in the diameter range from 50 to 250 mm, maximum precision in spite of high speed. The module system for reducing unit costs. The modular N1 product platform unites applications from different machining technologies. The benefit for users goes beyond significantly reducing investment costs to include the declared intention of this development: Permanent reduction of unit production costs. PITTLER T&S GmbH, the traditional manufacturer of CNC lathes, has integrated operations such as drilling, thread cutting, counter-sinking, milling, grinding as well as final expanding and burnishing into the N1 platform in addition to turning. The offer is completed by our own integrated quality and process assurance modules as well as material flow components.

Highlights:

01
Parallel and turning machining

02
Flexible workpiece feed from the rear of the machine into the automation room

03
Loading via storage table for up to 45 minutes of standalone processing

04
Automatic part separation – no defined placing of the raw and finished parts necessary

05
NC lift-off holder for brake disc machining

The innovative solution for complete machining of rotationally symmetrical and cubic parts, based on proven designs. The modular concept allows the machine to be produced with 1 or 2 independent spindles and with one or two cross slides. The PV³ combines technologies such as turning, drilling, thread cutting, milling, skiving, grooving or grinding and gear hobbing as well as hard turning and grinding including integrated quality check in a monitored process, all in one machine. Unique, patented tool carriers allow this high application flexibility in the part diameter range from 400 to 1,600 mm.

The PRÄWEMA SynchroFine® XL gear grinding machine is laid out for profile grinding on internal and external gears, on disc and shaft-shaped parts. The machine is laid out in three versions and is suitable for generating gears for components up to Module 32 with an outer diameter of 2,200 mm. Naturally the machine offers an option for hobbing gears up to Module 8.The natural granite machine bed is your guarantee for the highest geometric precision as well as static and dynamic rigidity. The low heat expansion coefficient and high thermal capacity ensures maximum thermal stability. All values for long-term precision, rigidity and thermal stability are better than those achieved e.g. with steel, cast iron or polymer concrete.The motion stand (X1 axis) for the grinding unit also consists of natural granite. The Z1 axis (grinding stroke in axial direction of workpiece) is designed as a wear-resistant linear drive. This allows high feed rates with excellent precision. The pivot axis (B axis) for adjusting the workpiece helix angle is laid out as a wear-free torque motor. The axis can be clamped hydraulically for rough grinding. The stable shift axis (Y axis) allows optimum grinding wheel dressing, correction movements during the grinding process up to incorporation into five-axis grinding for corrections, scanning measurement of the teeth up to use of the grinding operation with revolving worm. The grinding spindle used for hob grinding has an automatic balancing system and structure-borne sound sensors for sparking in.
