Exsys Tool, the North American supplier of pL Lehmann rotary tables, has introduced the space-saving TAP five-axis rotary table for small, high-speed VMCs. The table enable users to increase productivity without buying a new machine.

The rotary table effectively creates a five-axis machining center for small and medium-sized workpieces as large approximately 5.9" (150 mm) cube. It is well-suited for automotive suppliers as well as the medical, watch/clock and precision mechanical parts industries, as well as contract manufacturing.

The table expands the company’s 500 series of modular multi-axis rotary tables. Adaptable to nearly any workpiece or production situation, the tables can be assembled into as many as 240 different configurations. More than 20 different clamping methods and behind-the-spindle accessories including rotary unions, special clamping cylinders and angular position measuring systems extend the system’s adaptability.

The compact tables use minimal space in the machine work envelope, easing tool access to the workpiece. The tables and spindles are designed to offer strong resistance to pull-out torque and axial force while providing high levels of clamping torque. Engineered for low power consumption, the tables also feature IP67-rated enclosures.

The series includes both single- and multi-spindle tables that are available in four-axis and four/five-axis versions. Swiveling bridge-style four-axis tables employ the Roto-Fix clamping yoke for machining of multiple parts. The tables’ backlash-free preloaded gear drives provide high torque and rotation speeds, with spindles capable of 47 to 111 rpm and cycle times for 90 degrees of 0.34 sec. The five-axis tables operate in simultaneous machining or productivity-enhancing 3 + 2 positioning modes.

  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
