Used SECURITY ENGINEERED MACHINERY / SEM LK-1 #9251422 for sale

SECURITY ENGINEERED MACHINERY / SEM LK-1 is a flexible machine tool designed specifically for small volume production and short run operations in the job company environment. SEM LK-1 is designed to handle high speed machining, milling, drilling and boring operations that are common in production shops. The machine is configured with a vertical spindle, horizontal spindle and a low profile spindle for both heavy duty and precision machining operations. The spindles are powered by servo motors and driven through a feed screw equipment to ensure accurate positioning. SECURITY ENGINEERED MACHINERY LK-1 is equipped with rapid traverse, two-axis digital readout, and digital pallet changer for automatic tool changing. LK-1 incorporates a rigid cast iron base, with hardened and ground ways, ensuring maximum accuracy and longevity of the machine. A high speed two-speed, low inertia spindle motor powers the spindles. The motors are powered by frequency inverters, ensuring smooth and consistent acceleration and deceleration. The spindles are cooled with liquid cooled circulating oil system. SECURITY ENGINEERED MACHINERY / SEM LK-1 is equipped with a hydraulic power unit which maintains constant consistent control over the spindle motors. A PC-based CNC control unit is integrated with the machine. It is equipped with a 12" digital color LCD display, keyboard, mouse, and jog wheel, for easy access to all machine functions. SEM LK-1 has good acceleration and deceleration rates to ensure quick cycle times. The rapid traverse speed of the machine is 2400 IPM (inches per minute) at three axes and a max RPM of 7000. The maximum load capacity of the spindles is up to 3.5kW and the allowable load radial and axial forces are up to 437NM and 529NM respectively. For added protection, SECURITY ENGINEERED MACHINERY LK-1 is built with an alarm unit and safety sensors which can detect and stop the machine if an unsafe condition is detected. Additionally, the machine features a spindle-sensing machine which provides feedback to the operator indicating if the spindle is running correctly or not, and a built-in lubrication tool for the spindles which can be adjusted for extended life. Overall, LK-1 is an efficient and highly reliable machine that can be used in small production runs and job shops. With its high speed spindle motors, rapid traverse speeds, and easy to use CNC control unit, SECURITY ENGINEERED MACHINERY / SEM LK-1 is a great choice for short run production jobs. The integrated safety features of SEM LK-1 make it a safe and dependable piece of machinery that can handle a variety of cutting and milling operations efficiently and accurately.
