Frequently Asked Question

FAQS For the Servo Press Industry

When should consider the NB-EX series?

NB-EX is optimized for small-to-medium batch production (e.g., electronics, household appliances) with a tonnage range of 25–300 tons. Its compact design and energy efficiency suit workshops with space or budget constraints.

What are the cost-saving features of NB-EX?

Lower energy consumption and noise levels due to optimized servo motor control.
Simplified mold height adjustment and ergonomic controls reduce operator training time.
Standard stepless speed regulation allows flexible adaptation to diverse materials.

Can NB-EX be upgraded with automation?

Yes, Automation tools (e.g., quick die change devices) are optional. The series focuses on core affordability while supporting basic add-ons like preset counters and knockout devices.

Is NB-EX suitable for high-precision tasks?

Absolutely. It meets Grade JIS 1 standards and offers practical electric lubrication as standard, ensuring smooth operation and consistent accuracy for small-part stamping.

What is a Servo Press?

A servo press (also called an electric servo press) is a high-precision stamping machine powered by a servo motor + control system. It directly drives the crankshaft or linkage mechanism without traditional components like flywheels, clutches, or brakes, enabling programmable control over stroke, speed, and force for energy-efficient and flexible operations.

Servo Press vs Hydraulic Press

Choose a Servo Press if: You need high precision, energy efficiency, and flexibility for tasks like blanking, bending, or progressive stamping.
Choose a Hydraulic Press if: You require high force for deep drawing or heavy forming where speed is less critical.
