Frequently Asked Question

FAQS For the Servo Press Industry

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

Which Press is right for your needs?

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.

Feature	Servo Press	Hydraulic Press
Precision	±0.01mm (JIS Grade 1)	±0.1mm (lower due to fluid compressibility)
Speed	High (up to 1200 SPM)	Low to medium (typically 10-60 SPM)
Energy Efficiency	30~60% energy savings	High energy consumption
Flexibility	Programmable stroke,speed,and force	Limited motion control
Maintenance	Low (no hydraulic oil or seals)	High (frequent oil and seal changes)
Noise Level	Quieter (10~15dB lower)	Louder (pump and fluid noise)

Servo Press vs Mechanical Press

Our servo press adopts direct servo motor drive technology, offering the following advantages over traditional mechanical presses:
