Five-Axis Gantry Machining Center PM-U Series
Features
This series of products is a self-developed fixed beam five-axis gantry machining center with compact structure, excellent performance, high speed, high precision, high rigidity, etc. It is suitable for machining parts in a variety of industries such as aerospace, engineering machinery, rail transportation, precision molds, wind power, etc.
PM-U Series
It adopts high-speed and high-precision A/C double swing head and is equipped with a high-power and high-torque electric spindle, which has strong cutting ability.
A/C double swing head
Gantry type CNC milling machine adopts imported high-precision, high-dynamic double swing heads and is equipped with a high-speed, high-torque electric spindle, meeting the high requirements for component precision, surface quality, and processing efficiency.
High rigidity structure optimized design
Finite element design methods are used to conduct static and modal analyses of various parts of the CNC gantry machining center to further optimize the product structure and achieve high-rigidity and lightweight structural design.
Screw auxiliary support structure
The long-travel lead screw is equipped with a floating support, which can effectively improve the limit speed of the lead screw and the stability of high-speed rotation.
Tool magazine
Various types of tool magazines, 24/32/40/60, are available to effectively shorten auxiliary machining hours.
High rigidity support
The machine bed is equipped with three large-size guides, which provide sufficient support rigidity and precision retention.
Humanized safety design
The sheet metal labyrinth design at the bottom of the worktable prevents iron chips from entering the CNC gantry milling machine bed. The integrated chip removal trough fundamentally eliminates the problem of water leakage.
