The N20TB and N30TB Crankshaft Turn-Broachíng Machínes have been conceived for turning and turn-broaching operations on truck and passenger vehicle crankshafts with lengths of up to 1,800 mm.
The two machine sizes are based on robust machine beds in composite construction. The machine construction design is identical and only differs in size and technical performance. Symmetrical work spindles are designed as motor-driven spindles and are synchronized electronically. For this process,
the work spindles are equipped with optimized bearing supports. Standard spindle noses (A8 for N20 and A11 for N30) according to DIN 55026 are used.

CNC-Turning-Milling-Drilling Centres MC-Series
The MC Seríes Horízontal Turning-Míllíng-Dríllíng Centres have been conceived for universal complete machining of rotationally symmetrícal work pieces. Using the sízes N20MC through N60 MC, various work pieces with lengths of up to 8,000 mm and swings of up to 1,500 mm can be roughed and finished in a complex manner.
Typical applications in the automotive sector are machining of one-offs and small batch productíon such as prototyping and spare parts manufacture.
On the MCM Mu1tí-S1íde Machíning Center, the universal turning, milling, and drilling head is combined with a powerful crankshaft milling unit for complete machíníng of crankshafts. This
combinations permits efficient prototyping of passenger vehicle and truck crankshafts and small lot
production of crankshafts for stationary engines. An essential advantage here is the powerful external milling unit, combined with the universal turning, milling and drilling head. This modular design enables
the combination of heavy duty roughing processes for heavy stock removal rates during the machining of bearings and counterweights of crankshafts combined with high-precision processes such as oil
hole drilling, gear milling, hard turning and hard turn-milling. The possible applications covered, range from complete soft machining up to semi-finishing or hardened crankshafts.

Deep-Rolling and Roll-Straíghtening Machine
The preparation of fillet radii on main and pin bearings of crankshafts is a decisive criterion for their durability. To enhance fatigue strength, Hegenscheidt successfully introduced a newly developed technology, the deep-rolling process, into crankshaft manufacture. Using this process, compressive residual stresses are induced in the fillet radii of crankshaft bearings to enhance the fatigue life. Usíng
the Models 7893R and 7895 Deep-Rolling and Roll-straíghteníng Machínes manufactured by HEGENSCHEIDT, higher engine power output can be achieved in the automotive industry worldwide.
This technology became innovative due to the angle dependent deep-rolling and subsequent roll- straightening. Right from the development up to the current state of the art, the NSH Group was
granted several patents for technologies and machine designs. Thanks to the use of this crankshaft machining process for compact engines in the automotive industry, material savings are achieved, quality is improved and durability considerably increased.

■ Flexible machine layout for deep-rolling and roll-straightening of crankshafts with different
strokes, bearing pitches and quantity of bearings
■ High in-process reliability due to monitoring of all machining parameters
■ Ang1e dependent deep rolling to minimize the radial run-out
■ Intelligent roll-straightening program
■ Gauging of radial run-out on all main bearings

HEGENSCHEIDT has developed the model 7794U-1NC for fine-turning and roller-burnishing of
thrust walls. Thanks to the fine-turning operation, the parallelism of thrust faces is considerably enhanced due to the high machining precision and machining tolerance. The successive rollerburnishing operation decisively increases the contact ratio of thrust faces along with excellent
running properties.
Short cycle times and high tool lives for both fine-turning and roller-burnishing tools were in
the foreground for the NSH Group to develop these machines. Using the model 7794U-2NC,
the flange face, reluctor ring and other features can be machined by means of an additional
NC-driven cross slide. Because additional machining takes place in the same setup, optimal axial
machining tolerances can be achieved.
