CORMAK BS370H

CORMAK BS370H Semi-Automatic Metal Band Saw

The CORMAK BS370H is a robust semi-automatic band saw designed for precise cutting of tubes, profiles, and solid materials.

The latest version is equipped with an upper clamping system for bundle cutting and variable blade speed control via an inverter, adjustable from 20 to 90 m/min. These enhancements increase the machine’s versatility and make it easier to adapt cutting parameters to different types of materials.

The upper clamp stabilizes stacked workpieces and minimizes movement during cutting. This allows for more efficient cutting of bundles of profiles, tubes, and other repetitive components.

Key Advantages
Upper material clamp – stable and efficient bundle cutting.
Variable blade speed (20–90 m/min) – speed adjustment via frequency inverter.
Semi-automatic operation – hydraulic material clamping, saw head lowering, and automatic return.
Mitre cutting from -45° to +60° – wide range of cutting applications.
Hydraulically operated vise – fast and repeatable workpiece clamping.
Infinitely adjustable downfeed rate – greater control over the cutting process.
Blade guides with carbide inserts and bearings – precise blade tracking and improved cutting accuracy.
Closed-loop coolant system – cools the cutting zone and dissipates heat effectively.
Blade tension indicator – convenient monitoring of correct blade tension.
Automatic shut-off in the event of blade breakage – enhanced machine protection and safety.
Efficient Bundle Cutting

The integrated upper clamp allows multiple workpieces to be securely held in place when stacked on top of each other. This is particularly beneficial for serial cutting of profiles, tubes, and other materials with repetitive dimensions.

The material is secured both by the hydraulic vise and the upper clamp, reducing movement and lifting of individual pieces within the bundle as the blade passes through the material.

Variable Blade Speed Control

The blade speed can be continuously adjusted between 20 and 90 m/min. The inverter enables precise adaptation of cutting parameters according to the material type, cross-section, and specific cutting requirements.

Semi-Automatic Operating Cycle

Once the material is positioned and the cutting cycle is started, the machine automatically performs the following operations:

The hydraulic vise clamps the workpiece.
The saw head lowers at the preset feed rate.
The blade performs the cut.
A limit switch detects completion of the cutting cycle.
The saw head is hydraulically raised back to its starting position.

The swiveling saw head enables cutting angles ranging from -45° to +60°. The material remains stationary while the operator adjusts the required cutting angle by rotating the saw head.
