In the diameter range from 100 – 630 mm customers frequently have additional requirements - such as high unfinished part allowances for machining - high degree of complexity of parts - high part weights. The PV SL 2 / PV SL 3 machine platforms take such requirement profiles into consideration. The sturdy, high torque and high performance design ensures efficient production of parts even with high allowances or allowance variations. Various sizes of operating chambers are available for processing. This ensures sufficient space for auxiliary operations such as drilling, milling and grinding. In practice this means fewer chucking operations.High performance reliability In the diameter range from 100 – 630 mm customers frequently have additional requirements - such as high unfinished part allowances for machining - high degree of complexity of parts - high part weights.

If you want to accelerate progress, you need better brakes.

Progress in automotive development always pushes the limits of what is technically feasible. Increasingly, however, there are also additional requirements today, such as efficiency, sustainability and environmental compatibility, as demonstrated by the new Euro7 standard.

Combining the demands of top technical performance with those of environmental compatibility is a challenge in itself. To implement the whole thing efficiently and economically is clearly a case for DVS UGrind.

• Double-sided machining in the double surface grinding process
• extreme dimensional accuracy due to in-process measuring method
• fast loading and unloading by robot systems

In order to machine the latest generation of brake discs using the double surface grinding process, we have equipped a DVS UGrind with two opposing grinding spindles. We ensure dimensional accuracy by means of in-process measurement. In the machine, the position in the Z-direction and the thickness of the brake disc are determined before machining. On this basis, the brake disc is ground to size on both sides.

The DVS UGrind 800 is designed for workpieces with tip widths of up to 1,200 mm, while the DVS UGrind 1500 is recommended for larger ones of up to 1,800 mm. Both workshop machines for universal hard finishing feature the same advantages and reduce machining times by up to 80%.

DISKUS WERKE Schleiftechnik‘s double face grinding machines are noted for their tremendously fast cycle rates and, thus, their high capacity. In order to optimally utilise this potential, all DISKUS automation solutions are tailored to specific process needs and customer requirements. The DDS-L automation series ranges from simple stacking magazines to fully automatic loading by robotic arms.

In DDS - XR series machine, a transfer disc moves the workpieces through the grinding zone. This method allows the coplanar grinding of workpieces of very different shapes. Depending on the machine confi guration, four different grinding methods are available. This makes the DDS - XR series the ideal candidate for machining a broad range of workpieces at top-level quality in a fl exible and economic manner. Its small footprint and an operating panel on just one side facilitates an automated setup of the grinding machine while leaving the option of manual loading for small batches.

The new type of machine DDW 1060-1600 is an high-precision grinding machine. Its double face grinding operation allows for n economical production of plane parallel surfaces. This process creates high parallelism tolerances, flatness and surface quality.

A side face grinding machine with two vertically installed grinding spindles. These build in motor grinding spindles have variable r.p.m. and are mounted onto two cross slides. Each of them can move individually in vertical and horizontal direction. With help of the 600 mm diameter grinding wheels and the cross slide movements, the machine can be set to the geometry of the work pieces. This machine is mainly used to grind the small and the big end of connecting rods, no matter if these are for passenger cars or for truck engines. For example, the small end and big end of coplanar or non coplanar connecting rods of commercial and passenger vehicles can be machined on both sides and the trapezium as well.

CNC 335 G Female thread grinding machine The natural granite machine bed on the CNC 335 G female thread grinding machine guarantees high precision.
