PREZISS Tooling solution for machining of turbo chargers

A Turbo Charger is a turbine device that increases the combustion efficiency and power output of engines. This complex aluminium component requires the engagement of accuracy and reliability in production as a Key takeaway point in a balanced compromise to success. At Preziss have the Knowledge and know how to achieve the comprehensive production of turbo Chargers with engineered PCD tooling solutions.

A preliminary rough boring tool that acts in one shot pass to finish the committed mesurements with a full integrated profile PCD fine boring tool capable to finish in tolerance and roughness. An optimized cutting geometry for a belt machining tool for the efficient circular milling external areas and a full PCD drill for a high performance hole making. All cutting tools are delivered for internal cooling and fine balanced.

Machining Steering Knuckle

In automotive suspension, a steering knuckle is that part which contains the wheel hub or spindle, and attaches to the suspension components. The wheel and tire assembly attach to the hub or spindle of the knuckle where the tire/wheel rotates while being held in a stable plane of motion by the knuckle/suspension assembly. Steering knuckles come in all shapes and sizes. Their designs differ to fit all sorts of applications and suspension types. However, they can be divided into two main types. One comes with a hub and the other comes with a spindle.

We developed a highly effective production tooling system that ensures the machining process is of excellent quality surpassing all accuracy and roughness requirements hoped in the fine boring housing as the hight performance achieved in the milling operations where configured an engineered by multi-tasking milling trains capable of machining in one pass and the optimized rough and drilling sequence that avoid downtimes by tool changes and unforeseen events during the component machining.

Tooling solution for aluminium cylinder head

Cylinder heads need to be robust. They have to withstand huge pressures and very high temperatures, while retaining their shape and form to seal the cylinder block via the head gasket. They’re key to controlling air flow in and out of the cylinders and fuel deployment. The inside of the cylinder head contains a number of passages – known as ports or tracks – and the air mix travels along these to the inlet valves. Other tracks inside the cylinder head are the route by which the exhaust gases travel when leaving the main engine block.

Precision Fine boring tools for the machining of the valve guide and seat. The seat cutting tool element ensures gas tight seals and  achieve the dimensional stability of the valve seats. the PCD reaming tools produce a perfect and accurate valve guide, thanks to its double entrance and multiple cutting edges reducing cycle time processes.
The Line Boring cylinder head camshaft housing with the piloting tool and the line boring reaming tool must have high accuracy to meet the requirements needed to achieve the diameter in the head casting and one half in a separate cap or carrier.

Machining Transmission Housing

A transmission is a machine in a power transmission system, which provides controlled application of the power. Often the term transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device. The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted.

Spot face, profiling, back boring and reaming all operations that can be mixed in one tool to optimize the machining process with advanced cutting parameters that reduces cycle time.
