HIGH PRECISION
» Precision NSK and SKF bearings installed on spindle to ensure accuracy and rigidity for heavy cutting.
» Maximum cutting depth can be 8mm and roundness reaching 3 micron (200mm long).
DURABILITY
» Heat treated and precision ground alloy gears.
» Wear-resistant phosphor bronze lead screw nuts.
» Cone clutch overload device in apron to ensure safety when operating.
» Heavy clamping tailstock -- Increased rigidity through greater clamping surface.
LUBRICATION
» Bedways of cross slide and bed are automatically lubricated with a lubrication pump that lubricates as the carriage moves.
» Oil bath lubrication for cross feedscrew & nuts provide extra degree of protection and prolong service life.
MEEHANITE CASTING
» Heat treated Meehanite casting bed. Hardness of bed reaching HS70 (approx. HRC 53)
» One-piece base combines high rigidity and good vibration dampening characteristic.
CONVENIENCE
» Universal gearbox for both inch and metric threading — conversion table is also included.
» High-capacity coolant system with 1/8HP coolant pump offers ample coolant output.
