Counter Pressure Casting (CPC) machines have been developed to utilize the counter pressure casting process. With more than 40 years of experience using counter pressure, we are able to exceed our customers’ requirements for efficient production of aluminum castings in permanent, sand or combined molds.

Our equipment produces castings that exceed the highest requirements for mechanical properties, structural strength density, surface smoothness and dimensional accuracy. Each machine is designed to control all parameters of the CPC process while providing simple and reliable operation with minimum maintenance.

With the ability to operate in counter pressure or low pressure mode, the CPC 1303 is the most versatile machine available on the market.

Drake Manufacturing is committed to producing precision CNC machine solutions and providing legendary service for global customers in the thread grinding industry.

The GS:DS combines the grinding capabilities of two machines into one. Depending on application, machine can be equipped with two external grind spindles, two internal grind spindles, or one of each. This not only eliminates changeover, but also reduces takt time while maintaining tight tolerances. A programmable B-axis allows for the wheel to grind both straight and taper sections in one set-up providing excellent concentricity.

The fully automatic CNC-controlled P 100 / P 100 L precision measuring centers are designed as compact units for the workpiece diameter range up to 1000 mm and 1250 mm respectively. The machines are used to inspect cylindrical gears, pinion type cutters and shaving cutters, worms and worm wheels hobs, bevel gears, general dimension, shape, and positional deviations of axially symmetrical workpieces., cam and camshaft measurement and rotor measurement.

The fully automatic CNC-controlled P 26 precision measuring center is designed as a compact unit for the workpiece diameter range up to 260 mm. The machine is used to inspect cylindrical gears, pinion type cutters and shaving cutters, worms and worm wheels, hobs, bevel gears, general dimension, shape, and positional deviations of axially symmetrical workpieces, cam and camshaft measurement and rotor measurement.

The fully automatic CNC-controlled P 65 precision measuring center is designed as a compact unit for the workpiece diameter range up to 650 mm. The machine is used to inspect cylindrical gears, pinion type cutters and shaving cutters, worms and worm wheels, hobs, bevel gears, general dimension, shape, and positional deviations of axially symmetrical workpieces, cam and camshaft measurement and rotor measurement.

After chamfering with the patented ChamferCut technology, no additional machining is necessary. There is no need for a second cut, which is often required during the deformation-based deburring process for the removal of build-up material. With the chamfering process, the exact chamfer form is produced. In contrast to deformation-based processes, the material structure is not affected. An optimal starting point is created for the subsequent finishing of hardened gears, particularly gear honing. The quality of such chamfers defines a new standard – with maximum repetitive accuracy.

Chamfered edges of gears prevent damage during workpiece transport, heat treatment cracks and gear wear. They facilitate the assembly process and improve the tool life. Chamfering with ChamferCut delivers a high-quality chamfer with repetitive accuracy – and is more cost-effective compared to press deburring and deburring with end mills. Chamfering is very popular among car and commercial vehicle manufacturers, as well as in gear and engine manufacturing. The process can also be integrated into existing production systems.

With the machines LS 80 – LS 180 Liebherr is introducing a new series of production gear shaping machines. The performance and flexibility of these machines are optimized for high production requirements.

The machines are based on a common modular platform with proven components from the hobbing machine platform. Especially noteworthy are the direct table drive and the thermo-symetric, liquid-circulated machine bed.

For small face width parts, a RAPID version with max. 3000 strokes/min. is available. For tapered gears all models can be equipped with a swivel-type column for up to 12 swivel angle.

For the dry machining process, efficient and fast chip separation is a major prerequisite. The process energy involved and the disposal of hot chips should not adversely affect the geometry of the machine. The redesigned work area with stainless steel lining improves the chip discharge.

The extremely short cutting times require short loading and unloading times. Modular automation systems are available for various types of workpieces, supplemented by integrated and peripheral workpiece storage systems.
