AC-1800

DESCRIPTION
• Spindle auto speed shifting (3 steps) and CNC controlling.
• All casting are made of high tensile Meehanite cast iron which are annealed treatment to eliminate internal residual stress.
• Wide bed and box constructed, bed ways are high frequency heat treated, precision ground etc., to provide stability at high speed running or deep cut.
• Spindle & gear are made of CR-MO alloy steel which are carburizing & precisely ground, forced lubricating & oil bathed combined in headstock which can be prolonged servicing life.
• Three point support on the spindle with two taper roller bearings and one roller bearing to assure the accuracy & rigidity.
• High precision ball screw.
• CNC & Manual operation
• Tool radius & geometry compensation
• Constant surface speed for model with infinitive variable speed
• 8 bit bus, 32K RAM
• Serial port (RS-232 communication)
• Teach-in mode
• Semiautomatic, automatic (Cycle) and part program modes
• Rapid travels
