Hwacheon TTC-10

Twin spindle turning center

TTC Series

Built to order. Ask for lead time.

Overview

10 + 10 in. twin spindle lathe, two 12-station turrets, Ø400 x 203 mm

The TTC-10 is a twin spindle turning center with two 10 inch spindles side by side, each with its own Z axis and 12-station turret, built for flanges, wheels, brake discs and similar parts. The two sides run independently, work passes easily from the left spindle to the right, and Hwacheon designs the machine for gantry loader, loader or robot automation. Each side swings 500 mm, cuts up to 400 mm in diameter and 203 mm long, and runs an A2-8 spindle to 2,000 rpm (3,500 rpm optional) on an 18.5 / 15 kW motor. Box ways, 30 m/min rapids and a 0.4 second turret index run on a two-path FANUC 0i-TF.

Features

01Independent twin spindlesTwo A2-8 spindles sit 460 mm apart, each on its own Z axis, and run independently so work passes from the left spindle to the right. Spindle bearings are grease lubricated for life.
02Two 12-station turretsColumn-type turrets with hydraulic index motors index in 0.4 seconds per step and take 25 mm square OD tools and 50 mm boring bars.
03Box ways, direct-coupled ball screwsX and Z run on Turcite-lined box ways, with servo motors coupled to the ball screws without intermediate gears, at 30 m/min rapids.
04Built for automationHwacheon lists the 460 mm spindle spacing and the 350 mm from the machine front to the chucks as its structure for automation, with easy fitting of a gantry loader, loader or robot. Twin automatic doors are an option.
05Simultaneous roughing and finishingIn Hwacheon's cutting test, roughing on one spindle while finishing on the other held 1.5 µm roundness on a 90 mm diameter, 100 mm long part.
06Separate coolant tank and chip coverThe coolant tank and chip cover stand apart from the bed to keep heat out of the machine and ease cleaning. Chip conveyors can be laid out to the back, left or right (option).
