Chapter 1 Product Overview

1.1 Product introduction

This product is equipped with the shear machine dedicated numerical con trol device which
is applicable to various users. Based on ensuring work precision, the cost of numerical control
shearing machine is reduced significantly.

Features and functions of this product are as following:

 Back gauge can be controlled.

 Cut-angle can be controlled.

 Cut-gap can be controlled.

 Stroke time can be controlled.

 Intelligent positioning control.

 Unilateral and bidirectional positioning which eliminates spindle clearance effectiv ely.

 Retract functions.

 Automatic reference searching.

 One-key parameter backup and restore.

 Fast po sition indexing.

 40 progr am s s torage space, each program has 25 steps.

 Power-off protection.
