Hwacheon Machinery offers its VT-950/1150 series of vertical CNC lathes, ideal machines for large-part turning, with 43.3 and 53-in. swing over the bed and cutting diameters to 52 in. with chucks sizes from 24 in to 40 in.
Precision hand-scraped and polished guide ways in all axes and rigid one-piece machine bed design mean the VTLs from Hwacheon are designed to absorb vibration and provide optimum stability in hard turning applications.
A rapid feed (X/Z) of 944 inch/min permits quick positioning of the tools. A 12- or optional 24-station servo-type tool turret, carrying tools up to 2.5" dia. offers indexing time of just 0.2 sec, helping to reduce cycle time.
The machines can include a turnmill option to provide even greater machining flexibility for completing more complex large parts complete.
The machines also may include Hwacheon's Lathe Tool Load Detection System software which constantly detects and diagnoses the tool load during machining to reduce tool wear and prevent damage, optimizing tool life.
VT-950/1150 range has an integrated 45-degree angle bed frame to minimize heat distortion. The unique bed design absorbs the vibration sufficiently, to ensure high degree of precision at hard turning.
The VT-950 and VT-1150 spindles provide powerful chucking for stable, precise machining. The Hwacheon clean room assembly facility, where these super-precision, super-rigid spindles are manufactured, maintains optimal temperature and humidity, resulting in spindles that meet the toughest quality standard in the industry. All Hwacheon spindles are oil-cooled.
The geared drive system allows for high-torque turning at low speed and also high speed turning. The transmission and the spindle motor are designed separately so that the heat and the vibration generated from the transmission don't interfere with the spindle motor. For the VT-1150, maximum spindle speed is 630 rpm generated by a 73.5 hp motor. The VT-950 achieves 1125 rpm with a 40-hp drive.
