High rigidity one-piece bed The high rigidity one-piece bed supports heavy duty cutting with the adoption of Finite Element Method (FEM) analysis.
High productivity and reliability The NHP Series rapid traverse rate has been further increased with the adoption of a high speed axis drive system. The servo driven automatic tool changer (ATC) and automatic pallet changer (APC) improve parts durability and maintainability. The increased APC cycle time also improves productivity. The APC system provides an optional increased pallet size on the NHP550 and 6300 models.
User-friendly functions Various new user-friendly functions have been introduced to reduce the operator's work load.
Step guide-type high-rigidity bed supports even-higher productivity.
The main body is designed as a double-wall structure to prevent coolant leakage and achieves excellent maintainability.The step-guide bed structure supporting the column realizes high rigidity.
All the axes are fitted with roller-type LM Guideways and low-noise, high-precision ball screws to enhance durability.
All the axes are equipped with roller-type LM Guideways and 3-row angular thrust bearings at both ends to improve structural reliability.Low-noise, high-precision ball screws support high-accuracy axis feed.
The high-speed spindle is designed to minimize vibration and thermal error while offering the fastest acceleration and deceleration, thereby guaranteeing superior cutting performance compared to the competitors.
Designed to minimize vibration and thermal error while offering rapid acceleration and deceleration, the spindle guarantees excellent cutting performance from steel to nonferrous metal parts. Thanks to its increased rigidity, the spindle supports various machining from high speed cutting to low speed heavy cutting. In addition, the high-torque, high-speed built-in spindle delivers increased torque.
An oil cooler system is provided as a standard feature for long-term, continuous operation at high speed. The oil is cooled down in the cooler before circulating around the spindle bearings and built-in motor to minimize thermal error and deliver high-precision cutting.
Tool rigidity is enhanced by firm clamping by the spindle, while tool life cycle and cut-surface roughness are improved due to reduced vibration realized by 2-face locking.
The servo-driven ATC provides high reliability and reduces tool change time.
The ATC is capable of handling pot-type tools weighing up to 25kg(25lb) and chain-type tools weighing up to 30kg(66.1lb) at high speed using a servo motor, and fast tool indexing and spindle positioning.
The distance between the spindle and the center of the pallet has been reduced for heavier-duty cutting with shorter tools.
40 tools as a standard feature, in addition to various options.
The NHP Series provides 40 tools as a standard feature, and up to 376 tools as an option.
The servo-driven APC boasts high reliability with its stable, accurate performance and reduced rejection ratio.
APC system achieves increased productivity with fast and accurate pallet change. In addition to its excellent reliability, the improved APC has more space for the operator's convenience.
As a mechanism designed for precise pallet position repeatability, the air blower injects high pressure air into the location cones connecting the table to the pallet. This removes chips from the locating surfaces and ensures highly accurate pallet positioning.
The NHP Series provides more space for heavier and larger workpieces.
The NHP Series realizes excellent machining performance thanks to its improved structure and comprehensive tooling system.
High-rigidity machining can be carried out with precision accuracy and diverse functions.
Diverse optional devices and features are available to meet every customer’s specific requirements.
Chip disposal is very important to productivity and the work environment. To meet this requirement, the NHP Series enhances chip disposal performance and improves the work environment.
We offer a wide range of solutions that can be optimized to suit each customer’s needs.
The following hydraulic and pneumatic fixture options are available for setting up workpieces:
Doosan's linear pallet system (LPS) and multi-pallet system (MPS) provides users with maximized productivity, rapid installation and commissioning, and easy maintainability.
Designed to provide users with an optimised system, the LPSII linear pallet systems designed and constructed by Doosan, offering outstanding flexibility, including system extension and layout change.
Compared with standard machines that use 2-pallet type APCs, the MPS can automatically handle 7 to 9 pallets for an extended period. This function enables small quantity batch production using machining scheduling.
Ergonomic design guarantees users’ convenience and safety.
Internal footings and an anti-door-lock function are provided to prevent the operator from being locked in the machine and to guarantee the operator’s safety. The centralized service unit and screen panel enhance the operator’s convenience.
User convenience has been significantly enhanced with a new operation panel.
The operator’s panel has been redesigned and integrated for better usability. Additional, customized function switches (option) can be provided to maximize the operator's convenience.
Doosan's Easy Operation Package (EOP) supports the user with tool, help desk, operation, and pallet magazine functions among others.
Doosan's EOP supports the user with tool, help desk, operation, and pallet magazine functions among others to maximize operational efficiency and user convenience.
