CARLTON 4A is a professional Grade Machine Tool, manufactured by CARLTON Machine Works Inc., and specially designed for precision CNC machining and production of intricate parts. The machine bed is made of high-grade cast iron, which is especially durable and resistant to shock. The box way construction ensures flat and square alignment throughout the bed, and the Y-axis is fully supported for heavy-duty machining operations. The integral rib bed has extensive stress relief which reduces vibration and maximizes accuracy. Built atop the machine bed is the Ram Assembly; which allows for greater rigidity when machining heavy stock. It also houses the spindle, which provides optimal power and accuracy for its maximum speed of 12,000 rpm. To reduce resonance, the spindle is dynamically balanced which ensures a smooth cutting experience. The spindle is also fitted with a high-precision, double-row angular contact bearing which ensures protection against vibration and overloads. The drive systems are also of high quality and robust build. The X- and Y- axis feature an AC servo motor and an AC Servo Drive, both from Yaskawa, and the Z-axis is equipped with a Ball Screw/Nut Assembly. These drives allow for maximum accuracy and repeatability when machining intricate parts. The control system on 4A is what sets it apart. Fitted with the latest Fanuc 0i-T Control, the CNC system offers intuitive programming and motion control. It also boasts features such as 20 Spindle Speed Presets, Eight Programmable Tool Paths, Sixteen Tool Setups, and Auto Tool Setups on the Control Panel. CARLTON 4A also features a comprehensive operator's manual, which includes illustrations, component location, and maintenance guides. It is thoughtfully designed to be lightweight and ergonomic, and it is complete with all necessary accessories for optimal performance. Overall, 4A is an ideal choice for precision CNC machining and production of intricate parts; its robust design and top-notch components make it an exceptional machine tool for a wide range of applications.
