Equipped With
NEW SHARP STB-60 CNC BIG BORE LATHE
This is a heavy duty precision CNC lathe that can function at full horsepower during low and high speeds.
The large spindle bore and wide bedways are ideal for big parts and large mold work pieces.
This machine is available with option of 6", 9", 12" or 15" spindle bore, 37.7" swing over bed and 59" to 236" distance between centers.
The hardend and ground bedways are made from high quality Meehanite castings.
The spindle drive has 4 steps to deliver full power at all speeds.
The bedways and ballscrews are centrally lubricated with low level alarm.
The headstock is equipped with a heat exchanger to disperse heat and maintain spindle accuracy.
A full length chip conveyer and enclosed splash guard are all standard accessories.
