Product Introduction
STC series punch press machine are produce by Qiaosen machine factory, which built to meet or exceed JIS Class 1 accuracy standards. Qiaosen punching machine adopt forced Lubrication system with default monitor ensures the operation reliability.User-friendly design and all-function electric control system provide high automation compatibility.
Gap press frame made of high strength steel frames and Quenching & Grinding Process for Slide-Guide，which can make the press machine have minimizing deflection and high accuracy and provide increased tool life.
The material of presses crankshaft are forged 42CrMo alloy，precision-machined gears and other drive train components are designed for smooth power transmission, quiet operation and long life. STC series double crank press machine are dry clutch system，which has longer service life of the clutch system ，high single stroke rate and high torque outputs performance.
Siemens based control platform and user-friendly touch screen operation interface are standardized in all QIAOSEN’s precision press machine, make the puching machine provides ease of operation and expandable capabilities. Easy to integration with other automation system（Such as press transfer and robots）. Other brands of control can be furnished upon request.
