NRP series Marine Azimuth Thruster (FP/CP)
Arranged in Z-Drive or L-Drive, the azimuth thruster transforms reliably the power of diesel engine, electic motor or hydraulic motor into best thrust and thus improves propulsion effeciency and maneuverability.

PERFORMANCE
Materials of propeller, bevel gear and drive shaft are supplied by alloy steel and bronze parts manufacturer.
Propeller blade of low RPM and large diameter is matched with the high efficiency nozzle to improve the thruster efficiency and lower down the noise and vibration.
Modularized rudder propeller structure simplifies the system and makes the components easier to interchange and maintain.
Bevel gears are designed and machined in house to high precision, strong loading capacity and long service life.
Clutch: Built-in hydraulic or air pressure controlled clutch, external hydraulic clutch with reduction gear.
The accurate remote system is simple to operate, sensitive to respond and reliable during navigation.
Steering type: Hydraulic or electric motor drive.

CONTROL SYSTEM
NRP6000 remote system is a follow-up propulsion control system based on PLC controller. The steering control and main engine speed control can be done through a combined control handle in the bridge console. Rotate the handle horizontally, and the rudder propeller can be rotated around 360° , and move the handle forward and backward to govern the speed of the main engine. In case of the follow-up system failure, you can actuate the back up control system quickly to control the rotation and main engine speed, or can transfer to local engine control and rotation control.

CNC Milling Machining

CNC milling machining is a CNC machine tool trajectory by means of computer controlled machine, using high speed rotating cutting tool if you want to shape the material. With the size of products have become increasingly demanding, machining from the original two gradually changed to 3 axis machining, 4 axis machining, 5 axis machining center, precision can reach 0.001mm. us the maximum machine processing size: 500mm * 1000mm *600mm, 800kg machine under the maximum weight of workpiece, Machine tool spindle speed 20000RPM to ensure that the surface of the workpiece is smooth and clean.we often processed material of aluminum,steel, copper, stainless steel, titanium, POM, Teflon and so on. At the completion of high quality, high dimensional accuracy of CNC milling machining parts process, we will divided into rough machining and processing method fine to get the best effect, the margin size coarse and finish machining is 0.5 * 1mm. after processing some of the products after surface treatment such as plating polishing surface passivation.Sand (powder), anodic treatment (aluminum common CNC anodized black red blue anode, anode, anode). CNC milling machining is widely used in aviation, automotive, communications, medical equipment, electrical appliances, drone.


In addition to,we also provide high precision machining and precision machined parts,supply custom machining services and cnc machining services for small batch.
