Hwacheon Machinery America, Inc. (Lincolnshire, IL), a full-line builder of machining centers and CNC lathes as well as a key supplier to the automotive industry, offers its VT-450/VT-650 single spindle and VT-450/-650-2SP twin spindle vertical CNC lathes designed for mass production, reducing cutting times for automotive parts such as brake discs, brake drums, hubs and valves. The rigid tool turret offers high speed indexing, providing consistent and stable machining performance, ideal for high volume cutting of automotive castings and forgings.
These turning centers can be provided with the spindle on the left or the right side or as double machine where the operator can work on two machines with one control, the VT450/-650-2SP. The machines can also be provided with a turnmill option with 3,000 rpm spindle to provide even greater machining flexibility for machining more complex large parts complete. Additionally, the unique Lathe Tool Load Detection System software constantly detects and diagnoses the tool load during machining to reduce tool wear and prevent damage and optimize tool life.
These machines, respectively, provide 24 in and 35.3 in swing over the bed and handle cutting diameters to 18 in and 31.4 in. with 12 in and 18 in chuck sizes. The maximum turning diameter zone is designed to provide interference-free operations, providing same maximum diameter at full length even on larger workpieces.
A rapid feed (X/Z) of 787 ipm and 630 ipm permits quick tool positioning. An 8, 10, or 12-station servo-type tool turret on the VT-450/VT-650 series carries tools up to 2.5 in diameter offers indexing time of just 0.2 sec or less, helping to reduce overall cycle time. 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 do not affect the spindle motor. For the VT-450, maximum spindle speed is 2,500 rpm generated by an 18.5 hp oil-cooled spindle motor. The VT-650 spindle speed is 1,500 rpm.
The Hwacheon clean room assembly facility, where the super-precision, super-rigid spindles are manufactured, maintains optimal temperature and humidity, resulting in spindles that meet the toughest quality standard in the industry. The integrated 45 deg angle, one-piece machine bed design limits thermal distortion and absorbs vibration effectively and it guarantees high surface quality and precision at high speed. 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.
The fast and effective chip disposal and the environment friendly oil-water separation design contribute to production efficiency
Hwacheon Machinery, the largest of the Hwacheon group of companies, was founded in 1952. The fully vertically integrated builder is unusual among machine builders in that it casts its own bases and columns, hand scrapes box ways, and provides a full suite of software for each of its machines. Uncompromising quality and machine tool durability are essential for this company.
