Specifications
- High-strength cast iron (HT300) with tempering treatment ensures rigidity, stability and long service life for the double-column frame.
- A fixed cross-beam integrates beam and columns into a rigid door-shaped structure to maintain machine solidity and alignment.
Movements
- Large twin V guides on the base and worktable provide steady table travel and long-term alignment stability.
- Vertical and longitudinal travels use high-precision ball screws driven by Baldor AC servo motors (PNC type) for accurate positioning and micron-level feed control.
- Grinding heads run on high-strength S55C steel rails with ultra-precision linear roller bearings for smooth cross travel and precise cutting.
- Vertical head angular positioning is driven by an AC servo on a worm-shaft transmission with numerical indexing to 0.1° for fast, accurate angle grinding.
Spindle & Motor set
- In-house assembled cartridge spindles use six super-precision CP4 angular contact bearings with permanent lubrication for low noise, low heat and high accuracy.
- High-torque Japanese V3-grade spindle motors are fitted on double-column models and dynamically balanced to minimize vibration and noise during extended operation.
- Motors are directly coupled to the spindle for optimal torque transmission and reduced vibration.
Lubrication
- Force-coverage lubrication (oil flows from upper to lower railways) prevents oil pulsation impact and ensures smooth sliding movements.
- A sensor monitors lubrication pressure and disables table movement if oil pressure is abnormal to protect the railways.
Hydraulic system
- Electronic control circuits manage a proportional hydraulic valve for precise hydraulic functions.
- Operator can adjust worktable speed directly from the control panel to optimize productivity.
- Hydraulic oil temperature is stabilized by a Habor coolant system to protect components during long operations.
Control System (PNC type)
- DSC-based NC control integrates machine functions and movements into a single panel for centralized operation.
- AC servo motors are used for both vertical and cross feeds under numeric control for repeatable precision.
- LCD display and digital panel inputs provide straightforward operation for various grinding applications.
- User-friendly design reduces the need for complex programming during typical production tasks.
