Production automatic sawing machine
- Published: March 10, 2017
BLM Group USA has introduced the CM602 automatic CNC sawing machine that can handle tube and bar up to 102 mm (4 in.) in diameter, depending on the material and can achieve blade speeds up to 5,000 rpm.
BLM says it is ideal for cutting short and medium length steel, copper, brass and aluminum tubes, as well as solid bars and custom profiles. Its compact layout, rugged construction and precise handling of the material during the entire cutting process makes it a good choice for continuous production operations.
The CM602 is an operator-friendly machine. The operator is assisted with detailed step-by-step instructions via icons on a touchscreen panel. By entering the tube shape, material thickness, the cut length and the material type, the machine selects the appropriate blade from its library, calculates the stroke, the cutting head feed rate, the blade speed, and then monitors the chip load to prevent the blade from being over-loaded and developing damaging excessive heat.
The material is loaded into the cutting area by a servomotor carriage, providing highly repeatable positioning and accuracy of the cut lengths. At the end of the cut, during the return movement of the head, the bar is retracted to enable its detachment from the blade which preserves the material’s end finish and increases the saw blade’s lifetime.
The cutting head is positioned at 45° to the tube surface. Its linear movement across the tube provides a uniform load on the blade resulting in reduced noise and less scrap.
