When I decided to invest in a shearing machine, I realized that choosing the right one was crucial for my operations. In my journey of understanding how to select the best shearing machine, I discovered several key factors that made all the difference. From blade quality to machine durability, each aspect plays a significant role in performance and efficiency. In this article, I’ll share my insights and tips on how to select the best shearing machine, ensuring you make an informed decision that meets your specific needs.

Overview

Functions：The shearing machine applies moving top blade and fixed bottom blade ,with proper knife gap to any-thickness metal plate (such as mild steel , stainless steel, galvanized steel and aluminium sheet etc.),which can exert shear forces  to disintegrate metal sheet according to the size required. 

Types: Pedal shears , mechanical shearing machine, electric shears, swing beam shearing machine, guillotine shearing machine.

Pedal Shears

Principle：Pedal shears is a shearing machine sliding fixed fulcrum  to abate two-thirds of operating force. Partial machine tools equipped with pressure feeding has been proved to be of high quality , light weight and flexible movement , and are widely applicable to manual cutting in sheet metal industries. 

Features: No manpower or electric power , proper structure, automatic reset, portable pedal, cutting stopper and folding pedal installation, cutting quality : clean cut, no burr , to ensure the cutting accuracy . Power saving , convenient manipulation, economical and practical.

Mechanical Shearing Machine

Principle：Having been rotated by the connecting rod driven by the rack which is by through of electric engine ,eccentric wheel connected to rotation axis drives knife rest in seasaw motion to cut the sheet materials.

Model：Q11

Features：Simple structure , only foot control 、The whole mono-block cast structure、The backguage manual adjustment.

Electrical Shearing Machine

Principle：Having been rotated by the connecting rod driven by the chain which is by through of electric engine ,eccentric wheel connected to rotation axis drives blade adapter in seasaw motion to cut the sheet materials.

Model：Q11D

Features：Single and inching、Foot switch control、Better cutting velocity、The whole mono-block cast structure、The back guage manual adjustment.

Swing Beam Shearing Machine

Principle：The top blade is fixed on the knife rest, the bottom one is fixed on worktable . Knife rest moves round a fixed axle in to-and-fro motion ,curvilinear motion to achieve vertical cuttings over and over again. 

Model：QC12K/Y

Features：Top blade with two cutting edges and bottom blade with four cutting edges、Knife gap adjustment、Unadjustable shearing angle、A sort of bad performance when cutting thick material、Simple structure , low maintenance 、Knife rack returns by Nitrogen cylinder.

Guillotine Shearing Machine

Principle：Oil cylinders are installed on the both sides of the machine , driving knife rest in to-and-fro motion vertically , to achieve the linear cutting.

Model：QC11K/Y

Features：Top and bottom blades with four cutting edges、Knife gap adjustment、Shearing angle adjustment electrically、Knife rack returns by Nitrogen cylinders(or hydraulic return、Achieving a sort of good performance when cutting thick metal sheet.

Ⅲ、Parameter System

NC system：E21S（guillotine/swing beam）

Functions：Single/Cycle、Concession function 、40 programs stored, 25 steps per program、Work-piece counting、Control common motor or inverter.

NC system：DAC-310（angle function or gap function），DAC-360

①Knife gap adjustment

②Shearing angle adjustment

③Better performance with front feeder

④Shearing stroke control

⑤Back guage controlled by servo motor

Note:

Shearing angle：an angle formed by downward moving top blade and bottom blade.

Knife gap ：the distance between two blade sides.
