ZRAT is a company specialising in the provision of precision CNC machining for aerospace metal components. The company's services support the production of high-reliability parts used in fluid systems and other critical applications.
The primary focus of the company's machining capabilities is the production of aerospace tubing system components, with a secondary capacity to manufacture a range of custom machined parts and complex geometry components based on customer drawings.
This flexibility enables the company to manufacture both specialised fluid system hardware and general aerospace machined parts within the same controlled manufacturing environment.
The production environment is characterised by its integration of multiple CNC machining technologies, thereby ensuring both high precision and repeatable manufacturing.
The typical machining capabilities encompass:
CNC turning
CNC milling
Turn-mill machining
Multi-process machining centers
Precision drilling and tapping
Complex contour machining for irregular parts
These capabilities facilitate the fabrication of small precision components, which are frequently employed in aerospace assemblies and fluid systems.
Machining processes are designed to meet the tight tolerance requirements typical in aerospace applications.
Typical machining tolerance:
±0.01 mm
With optimized machining parameters and process control, equipment capability can achieve:
±0.005 mm
Maintenance of stable tolerance control is ensured via the implementation of controlled machining processes, inspection verification procedures, and the continuous process optimization.
Precision machining facilitates the production of tube fittings, connectors and other aerospace machined components, including custom parts manufactured according to customer drawings.
A substantial proportion of machining operations are dedicated to supporting tubing system hardware, with supplementary capacity available for complex geometry and irregular components.
A range of aerospace-grade metallic materials are utilised in machining operations.
Stainless steels
Aluminum alloys
Titanium alloys
Nickel-based alloys
Other customer-specified aerospace metals
Among these materials, steel, aluminum and titanium alloys represent the most frequently processed materials.
Precision machining processes operate within the company’s certified aerospace quality system.
Process control includes:
Controlled machining procedures
In-process inspection
Coordinate measuring machine (CMM) verification
Surface roughness inspection
Additional dimensional verification as required
The implementation of these measures guarantees the dimensional accuracy and reliability of the machined components, thus ensuring their suitability for aerospace applications.
