Overview
8 / 10 in. box-way lathe with standard Y axis, Ø420 x 1,273 mm
The Hi-TECH 350 is the Hi-TECH built around a Y axis: every version is YMC or YSMC, with live tooling, a C axis and 120 mm of Y travel. It is a box-way lathe with hand-scraped guideways, aimed at parts like valve bodies, connectors and flanges that need turning and milling in one setup. The 350A runs an 8 inch chuck at 5,000 rpm with Ø65 mm bar on 18.5 / 15 kW (22 / 18.5 kW optional), and the 350B a 10 inch chuck at 4,000 rpm with Ø76 mm bar on 22 / 18.5 kW. Max turning diameter is Ø420 mm and max turning length 673 mm, or 1,273 mm on the long bed.

Features
- 01Y axis standardY travel is 120 mm (±60 mm) at 10 m/min, with spindle indexing in 0.0001 degree steps, so turning and milling happen in one setup.
- 02Hand-scraped box waysAll guideways are box way, hand-scraped and polished to reduce vibration and hold precise feed during heavy cuts.
- 03One-piece bedThe single-frame bed is built to resist heat distortion and absorb vibration. Swing is Ø700 mm over the bed and Ø550 mm over the saddle.
- 04Sub spindle (YSMC)YSMC versions add an A2-6 sub spindle with an 8 inch chuck, 4,000 rpm and 7.5 / 5.5 kW, synchronized with the main spindle for first and second operations.
- 05Close loading positionThe spindle center is 474 mm from the operator and 1,160 mm off the floor, and the Z axis keeps way oil and coolant fully separated.
