WEISSER vertical and pick-up lathes

WEISSER is a German manufacturer whose roots go back to 1830 and which has built machine tools in St. Georgen (Black Forest) since 1856. It specialises in high-precision turning of rotational parts in series production, above all for the automotive industry: single- and twin-spindle vertical lathes that load and unload the workpiece themselves (pick-up), hard turning, multi-process turning platforms and automation solutions.

Brake discs

Safety-critical: must be produced in high volumes with short cycle times and process reliability. With Euro 7, hard-coated low-emission discs join grey-cast-iron discs in series production.

Gears and ring gears

As transmission output grows, gears, disc carriers, shafts and planet gears must be made in larger volumes, with high precision and flexible processes.

AlsoMarking · Nill + Ritz

Car and truck pistons

Critical for clean combustion and long engine life, with ever more complex shapes. Very tight outer-contour tolerances; aluminium and hardened-steel pistons of different types and sizes on one machine.

Vertical turning; non-round skirt profile · WEISSER
AlsoMarking · Nill + Ritz

Electric motor rotor shafts

Solid small-diameter shafts in electric motors; the lamination stack makes the rotor heavy, and every extra gram reduces an EV's range. Machined in complete cells with robot or gantry loading.

Automotive Electrical

Shaft turning and complete machining · WEISSER

Differential housings

An indispensable, complex-shaped connecting element of the drive train. Needs high volumes, error-free processes and short cycle times; turning is split into several sub-processes.

Automotive

Multi-stage vertical turning · WEISSER

Planet carriers

Modern automatic transmissions contain up to three planetary gear sets; the planet carrier holds their gears. Increasingly common thanks to high efficiency, compact design and high power density.

Yoke shafts

A drive component in commercial vehicles, agricultural and construction machinery. Yoke eye and cross holes are machined in few setups; bearing seats are pre-turned before hardening and ground afterwards.

Technologies

WEISSER technologies

These technologies are integrated into the machine and can be combined in one setup; most of them were developed by WEISSER.

Rotational turning

Developed and patented by WEISSER: workpiece and cutting edge rotate simultaneously, producing twist-free finished surfaces that can replace grinding. Machining time is up to 77% shorter than hard turning.

Out-of-round turning (HOT)

Three times the capacity with the WEISSER HOT system: high-output turning of combustion-engine pistons, camshafts, multi-edge profiles and polygon shaft-hub connections.

Universal machining

Turning and milling from bar in parallel with machining time: six-sided complete machining up to 105 mm diameter and 1,200 mm length. Fewer re-clampings, shorter machining times, lower unit costs.

End machining of shafts

Deburring, facing, milling, drilling and centring at the shaft ends; contour machining at the ends, from one or both sides.

Gear cutting: power skiving

An integrated skiving module cuts internal and external gearings with different helix angles and directions in one machine, combining hobbing and shaping in one continuous high-feed process.

Internal and external cylindrical grinding

Internal and external cylindrical grinding in one machine: hard finishing of rotationally symmetrical parts, combined with hard turning or rotational turning for optimum cycle times.

Whirling

Solid brass cages for heavy-duty bearings, replacing milling, drilling and broaching. For planetary gearboxes, wind-turbine gears, railway axles and construction machinery; concave pocket shapes let the rollers snap in.

4-axis machining

Simultaneous machining with two powerful disc turrets (4 axes): two tools work at once and machining steps are combined, cutting machining time and unit cost.
