High Precision Lathe
July 1, 2014
Knuth Machine Tools USA offers its new Servoturn high precision, non-CNC, high production lathe. According to the company, the Servoturn lathe incorporates features previously only found on CNC lathe machines.
"The Servoturn's mineral cast base is capable of reducing harmonic vibrations six times more effectively than fine grain (GG-25) cast iron and 10 times more effectively than steel," said a company spokesperson. "The heavy casting allows for improved piece part finishes at increased feed rates.
"The Servoturn is equipped with precision linear profile guide rails designed to provide stable and accurate load distribution. Typical maintenance is virtually eliminated with this linear guide rail. If the rails ever need to be replaced, the repair is simple and the replacement parts are readily available.
"Recirculating preloaded ball screws reduce backlash to zero. This zero backlash improves piece-to-piece accuracy, thereby reducing the scrap rate due to out of tolerance parts. Reduced friction between the moving parts helps minimize heat. There is no stick-slip found on the Servoturn's carriage."
Both axes are driven by a servo motor featuring electronic hand wheels. This lathe also has a teach in function enabled by buttons on the carriage. At any point in the machine's range of movement a button can be activated to set a fixed stop. Knuth's Servoturn incorporates a control feature that allows the threading operation to be conducted without a thread dial as that function is now controlled by the main motor for feed start and stop. Threading is optimized for easy operation.
The Servoturn lathe lineup includes the Servoturn 410 x 1000 with a maximum swing diameter of 16" over the bed and a center distance of 40". This lathe has a variable speed 3,000 RPM spindle with a 7-1/2 HP main motor. Also available is the Servoturn 560 x 2,000 and the 560 x 3,000, both featuring a variable speed 1,600 RPM spindle with a 10 HP main motor. These lathes feature a 22" maximum swing over the bed and a center distance of 80" and 120", respectively. Standard equipment includes 3-axis DRO, 3-jaw chuck, quick change tool holder and a coolant system.
