Our grinding machines have the following features:
Movements
Large twin V is adopted on the machine base and work-table railways, allowing rock-steady table movements, as well as maintains best alignment with equilibrium.
The grinding head movements (vertical & longitudinal travel) are guided by high precision grade ball-screws, and driven by Baldor AC servo motors (PNC type). These features facilitate accurate positioning and micron-precise feeding.
Moving on high density strength steel (S55C), with ultra precision grade linear roller bearings, the grinding head has firm and smooth cross travel with exceptional and accurate cutting ability.
Angular turn on the vertical grinding head is driven by AC servo motor on worm shaft transmission. Numerical insert on desired angle with accuracy to 0.1 degree allows swift angle forming grinding with excellent results.
Spindle & Motor set
High precision in-house assembled cartridge type spindle set uses 6 super precision CP4 grade angular ball bearings, sealed with permanent lubrication. This structural superiority empowers the spindle to grind with low noise, low heat rise, and high precision.
Japanese brand V3 grade high torque spindle motors are utilized on all double column models. They are thoroughly tested with kinetic balance inspections, capable of remaining low noise, low vibration, and high stability movements even after long period of operation.
V3 grade motor is integrated with spindle set via couplings for direct transmission, to obtain maximum torque and reduce vibration.
Lubrication
Force coverage lubrication (oil streams down from upper to lower machine base railways) avoids impacts from lubricant oil pulsation pressure, and allows smooth movements.
The detecting sensor will disable table movement to protect the railways when lubrication oil pressure is not normal.
Hydraulic system
Employs precise electrical circuit to control the proportional hydraulic valve.
The operator can adjust work table speed directly via control panel, increasing work efficiency.
Hydraulic tank temperature is maintained by Habor Coolant system. The coolant stabilizes oil temperature after long hours of operation to guarantee grinding precision and protect hydraulic system parts.
Control System (PNC type)
Our own design of DSC based NC control system integrates all functions & movements of a large machine into one panel.
Numerical Control system that utilizes AC servo motors on both vertical feed & cross feed.
LCD screen display with digital inputs on panel allows easy operation on various grinding applications.
Easy maneuver and user-friendly design make the machine operation simple, without having to learn complex programming.
