SC 4MM High-Precision CNC Shearing Machine For Sale

SC 4mm high-precision CNC shearing machine for sale is a hydraulic guillotine shearing machine for CNC shearing metal sheets with a thickness of 4 mm (usually carbon steel plates). It uses a CNC digital control system and a hydraulic shearing mechanism to automatically position and control parameters such as blade gap, shearing angle, and shearing length, thereby improving shearing efficiency and accuracy. It is widely used in metal processing industries such as steel structures, machinery manufacturing, electrical cabinet panel processing, ventilation ducts, and stainless steel processing.

1. Main Technical Components and Functional Modules of High-Precision CNC Shearing Machine

1) 4MM High-Precision CNC Shearing Machine Main Structure

Welded steel structure body: Stress-free treatment after overall welding, high strength and rigidity, beneficial to shearing stability.
Hydraulic shearing system: Stable hydraulic transmission and stable shearing force, suitable for heavy-duty cyclic work.

2) CNC System and Positioning Device

CNC System: Programmable settings for shearing length, number of shearing cycles, repeated shearing, etc., with intuitive digital display.
High-precision back gauge positioning: Driven by ball screws and linear guides, achieving positioning accuracy up to ±05 mm and shearing straightness up to ±0.03 mm/m.
Automatic/manual adjustment of blade gap and shearing angle: Adjusted according to material and thickness to optimize the quality of the sheared section.

3) Other Auxiliary Systems

Ball bearing support table: Reduces friction, avoids scratching of the sheet metal, improves work efficiency and material protection.
Safety protection devices: Front guard, safety light curtain, emergency stop button, etc., to enhance operational safety.

2. Equipment Features & Highlights

1) High-Precision Shearing Control

CNC back gauge and high-precision positioning device achieve minimal repeatability, significantly improving shearing dimensional consistency and processing accuracy.
