Headstock gears are made of Cr-Mo (Chrome Molybodenum) steel that underwent heat treatment and ground machining. Proper backlash value are adjusted to ensure high accuracy, high strength and low noise.
The spindle is mounted on three-point support, which consists of high precision taper roller bearings to endure radial and axial load. The spindle is designed with optimum bearing span analysis and proper preload arrangement to maintain spindle stiffness and lower thermal displacement.
No need to replace change gears when switching between inch system and metric system.
Rigid tailstock structure and clamping mechanism are the result of design emphasis on heavy duty cutting load. Dual speed feed is suitable for various thrust force from different axes.
The over-travel limit device prevents tailstock quill from falling.
Slide ways of saddle and cross-slide are applied with “Turcite B” coating and hand scraped; slide ways of bed are treated with ground and induction hardening to assure high accuracy and lower wear rate.
Bed width of 400mm(16 1/8”) and wide front slide way increase contact area to distribute cutting stress and reduce wear rate.
