Introduction

The COLMAL 30/8-10 hydraulic shear is an example of a high-quality used machine, equipped with advanced features that make it suitable for a variety of industrial applications. Manufactured by COLMAL, this used machine offers reliability and precision even after years of service. It was reconditioned in 2000 and comes with a warranty, ensuring that, despite its used condition, it maintains high standards of operation.

Construction and Components

The COLMAL 30/8-10 hydraulic shear is built with robustness and precision, combining high quality components:

• Frame : Reinforced steel structure to withstand the stresses of the cutting process and ensure stability during operation.
• Blade : Highly hardened steel blade designed for precise and long-lasting cutting.
• Hydraulic Cylinder : A large-capacity cylinder that generates the force required for cutting. This cylinder is responsible for moving the blade.
• Gap and Register : Managed by a numerical control (CN), they allow precise adjustments of the gap and position of the blade to adapt to different thicknesses and materials.
• Recess : 500 mm measurement, useful for positioning and processing larger pieces.
• Cutting Angle : Electric, offers fine adjustment of the cutting angle to achieve precise results.

Measures

The main dimensions of the COLMAL 30/8-10 shear include:

• Cutting Width : 3000 mm
• Max Material Thickness : 8 mm
• Gap and Register : Managed by NC, with a 500 mm gap.

These measurements make it suitable for working with medium-sized materials and considerable thicknesses.

Mechanical Characteristics

The COLMAL 30/8-10 has advanced mechanical characteristics:

• Cutting Force : High cutting capacity thanks to the power of the hydraulic cylinder.
• Precision : High cutting precision, improved by electronic management of the gap and cutting angle.
• Reliability : Rugged construction and quality components ensure long life and reliable operation.

Usage Procedure

To correctly use the COLMAL 30/8-10 hydraulic shear, follow these steps:

1. Preparation : Check that the machine is in good condition and that the hydraulic system is functional.
2. Adjustment : Use numerical control (CN) to set the gap and cutting angle according to the job requirements.
3. Positioning : Align the material with the 500mm recess and fix the position.
4. Making the Cut : Activate the hydraulic cylinder to make the cut. Make sure the material is stable and positioned correctly.
5. Inspection : Check the cut to ensure it meets the required specifications.

Matching accessories

The COLMAL 30/8-10 can be equipped with various accessories to improve its functionality:

• Support Guides : For greater precision and ease in positioning the material.
• Replacement Blades : To maintain cutting quality and extend the life of the machine.
• Vacuum System : To remove debris and improve visibility and safety while cutting.

Mathematical Formulas for Optimal Use

To determine optimal usage parameters, consider:

• Shear Force : The required force can be calculated using:

  $$F$$

  Where FF $F$ is the cutting force, PP $P$ is the applied pressure and AA $A$ is the blade area.

• Gap and Angle Adjustments : Make sure your electronic adjustments are set correctly to achieve even, precise cuts.

Workable Materials

The COLMAL 30/8-10 shear is designed to work with:

• Steel Sheets : Up to 8 mm thick.
• Aluminum : Suitable for cutting aluminum sheets of varying thicknesses.

Maintenance

To keep your COLMAL 30/8-10 in top condition, do the following:

• Lubrication : Apply lubricants to moving components and the hydraulic system.
• Checking the Blades : Check the blades periodically and replace them if they are worn.
• Cleaning : Remove debris and dust from the machine regularly to prevent premature wear.

How to Evaluate a Good Used Car

To purchase a quality used hydraulic shear, consider:

• General Condition : Inspect the machine for visible wear and damage.
• Operation : Test the machine to ensure that all functions are operational and that the hydraulic system is functioning properly.
• Maintenance Documentation : Request documentation regarding maintenance and any repairs performed.
