Hi-Tech 750A YMC Pre-
cisely Turns Large Parts
—Hwacheon
Hwacheon’s newly introduced Hi-Tech 750A YMC is designed to machine high-precision, heavy-duty parts. The machine’s extensive range of specifications can benefit numerous industries.
The turning center was designed to easily handle large parts, so whether users are machining hefty oil and gas parts or sizable heavy transport com- ponents, it is said to maintain precision and accuracy throughout the entire machining process. The company reports that accuracy is enabled by a high-torque, built-in, gear-driven
spindle that can reach 1,800 rpm. The gear-driven spindle not only reduces machining time, it also enhances pro- ductivity when combined with the machine’s y-axis and live tooling functions.
While the Hi-Tech 750A YMC is equipped with an 18” chuck, the Hi- Tech 750 B series comes with a 21” chuck. Both the A and B series can handle chucks as large as 24”, with maximum cutting lengths ranging to 4,250 mm and a maximum cutting diameter of 760 mm. Other features of the Hi-Tech 750A YMC include a wide door window for better visibility when machining large parts, rigid built-in tailstock, wide disc turret and milling function.
