Understanding bandsaw down-feed systems

When delving into the world of bandsaw machinery, a fundamental aspect to grasp is the relationship between the saw bow’s descent speed, the applied pressure and the resistance offered by the workpiece. This understanding is crucial for optimal operation and precise cutting, as a guide produced by Saws UK sets out.

Investing in a high-end bandsaw brings notable advantages, especially with sophisticated down-feed systems designed to fully harness the capabilities of the latest bi-metal and carbide-tipped blades. These enhancements substantially boost productivity. 

Down-feed regulation systems in bandsaws vary significantly. Some are straightforward, featuring an adjustable hydraulic valve in the guide system that responds to material resistance. More advanced systems include load detection on the blade drive motor, integrating an interface with a proportional down-feed valve in the hydraulics. Additionally, some machines employ a ball screw system connected to the interface for down-feed control. 

A pivotal feature in some bandsaws is blade deflection detection. This technology automatically slows the down feed to prevent crooked cuts when the blade begins to dull towards the end of its lifespan. 

Modern control systems often include a material directory, enabling operators to set reasonable down-feed rates based on workpiece size. However, this requires accurate data input and may not account for the annealed state of the material, where load detection systems can provide additional guidance during challenging cuts. 

The question arises: can a company justify spending up to £100,000 more for a bandsaw that fundamentally performs the same task? The answer lies in evaluating several factors, including expected service life, precision of cut, ease of use and speed of cut. Saws UK can provide advice in line with customer-specific applications.

How to maximise efficiency with cold saws

Cold saws are essential tools for numerous businesses needing clean, burr-free cuts on various metals. They also find widespread use in general fabrication and machine shops, as well as in structural steel fabrication, HVAC, automotive repair and shipbuilding. Cold saws offer a dependable and efficient method for cutting different solid and hollow metal sections. Dimakin offers a guide (tips and tricks) for improving the performance of cold saws.

It is important to consider the blade tooth count relative to the workpiece material. For example, if using too fine a blade for soft materials, the blade’s gullets will quickly clog, eliminating the machine’s ability to cut effectively.

For those likely to cut multiple materials or profiles over the machine’s lifetime, it might be worth considering a cold saw with the ability to vary speeds. Cold saws such as the CS-350-DM are ideal with their speed inverter dial, allowing infinite adjustment between 24 and 120 rpm. Another tip is to use the coolant system during operation. Coolant lubricates the blade, reduces heat build-up, improves cut quality and extends blade life.

A further important factor in cutting is clamping. Without securing material tightly, no blade will ever be able to achieve a good quality cut. Regular blade sharpening is a further contributor to optimal cutting performance. Dimakin not only offers brand new blades, but a blade resharpening service tool. Last but not least, it is important to maintain a clean a clean work area in and around the cold saw for cut quality. Regularly remove metal chips and debris to prevent them from hindering the cutting process or damaging the saw.

Dimakin offers a comprehensive line of cold saws, from basic single-speed models to feature-packed inverter-driven options with variable speeds.
