Frequently Asked Questions (FAQ)
What types of metal materials can this CNC horizontal band saw cut?
This series of band saws is designed to cut various types of metal materials, including carbon steel, alloy steel, stainless steel, and non-ferrous metals. It efficiently cuts both solid rounds and square shapes up to the designated max capacity of each model.
How does the gantry double column structure benefit the cutting process?
The stable gantry double column design provides high structural rigidity and strength. This ensures smooth operations, lowers vibrations during heavy metal cutting tasks, increases overall cutting accuracy, and extends the operational lifetime of the saw blade.
Can the saw blade speed be adjusted during operation?
Yes. These models feature controllable stepless speed regulation or gear adjustments (27/45/69 m/min) to meet different material hardness parameters and optimized sawing operations.
What brands are used for key electronic and mechanical components?
The machine uses highly reliable international components including an Omron PLC system (Japan), Schneider / Delixi electrical systems (Germany/China), and NSK bearings (Japan) to guarantee stable machine performance and longevity.
What is the function of the hydraulic vise system?
The hydraulic vice system operates automatically to ensure secure clamping force. This prevents workpieces from slipping or shifting during the heavy sawing process, ensuring precise cuts and optimal operator safety.
Is there a cooling system built into the machine?
Yes, standard models are equipped with two sets of cooling devices that automatically run during operation. The cooling flood system prevents the bimetallic blade from overheating and flushes waste metal debris from the cutting path.
