CNC Gantry Boring & Milling Machine

CNC gantry boring & milling machine has boring, drilling, milling, slotting and other machining functions; with right-angle milling heads and other attachments, it can achieve five-sided machining, making it ideal equipment for large parts such as steam turbines, generators and heavy machinery in metallurgy, energy, power and other industries.

Mainly Applicable:

  1. Complex shapesMachining Accuracy高,Parts that cannot be processed by general machine tools or where quality is difficult to guarantee;
  2. During the machining process,Must performMulti-processmachining,such as must be completed in oneSetupcomplete milling in、镗、Countersinking & Reaming或Tappingand other processes;
  3. Difficult-to-measure、Difficult-to-control feed、Housings or box-type parts with difficult-to-control cavity dimensions。

CNC Lathe

CNC Vertical Lathe

CNC vertical lathe is used for machining heavy workpieces with large radial dimensions and relatively small axial dimensions, complex shapes. Such as cylindrical surfaces, end faces, conical surfaces, cylindrical holes, conical holes of various discs, wheels and short shaft workpieces. Additional devices can also be used for thread turning, spherical turning, profiling, milling and grinding. Compared with horizontal lathes, workpiece clamping on horizontal lathes is more difficult. The vertical lathe spindle axis is vertically arranged, and the worktable surface is in a horizontal plane, making workpiece clamping and alignment more convenient. This layout reduces the load on the spindle and bearings, allowing vertical lathes to maintain working accuracy for a longer time.
