MGR Super Rotary Table Surface Grinder
The MGR super series is a moving column type, and there is no inertia change due to the weight of the workpiece. It can grind the inner diameter and outer diameter, suitable for medium and large-sized, large-diameter or heavy-duty parts requiring high-precision verticality or cylindricity. Compared with the horizontal grinding machine, this machine has more advantages for large workpieces. The processing parts can overcome the weight of the workpiece, and it is easier to load and position when placed vertically.
Machine Structure
High-rigidity box-type cast body, movable column type movement, without the influence of workpiece weight.
Axial
• X-axis, hydrostatic guideway and linear motor achieve nano-level high-precision movement and high-precision grinding surface.
• Z-axis, high-precision linear slideway and ball screw. Hydrostatic guide rail + linear motor. (optional)
Spindle
Optional
• Hydrostatic spindle with high damping and high vibration resistance makes grinding more stable.
• Direct motor drive, high efficiency and low vibration.
Rotary Table
The static pressure bearing is used to support the axial and radial directions, which has high vibration resistance, high rigidity, high rotation accuracy, and can carry high weight.
Roller dresser
High efficient dressing rate, long service life.
MGR Super Advantage
Linear Motor Precision Control
Conversational Interface
Clamping without workpiece weight issues
Rotary table capable of heavy loads
Micro feed
Flatness and concentricity are easy to control
Suitable for Medium and Large Workpiece Grinding
The MGR super series is specially designed for precision grinding of medium and large workpieces. The vertical structure can overcome the problem of horizontal clamping due to weight sagging. All models of this series are equipped with HRT hydrostatic rotary tables as standard, which can carry heavy-duty workpieces, run smoothly and with low vibration, and have excellent performance in geometric flatness, verticality and concentricity. The X-axis and Z-axis guide rails use HGW fully enclosed hydrostatic guide rails, with ultra-low friction coefficients, and there will be no "Stick-Slip" phenomenon during low-speed motion, the drive unit uses a linear motor, greatly improving the positioning accuracy.
CNC Controller System
The CNC controller system can process more complicated operations. The CNC control system has a conversational man-machine screen developed by us, which reduces the time for programming.
Increase Productivity
Vertical workpiece clamping does not have the problem of horizontal weight drooping, which shortens the time for workpiece correction. A single clamping can complete inner diameter, outer diameter and end face grinding.
Tool magazine - increasing productivity
The number of ATC customized 4 – 8 tools. Tool form can be arranged according to the process Reduce manual tool change time.
Rotary Table
Hydrostatic bearings are used to support the rotary table, axial and radial, and the table can be floated. It has high vibration resistance and can maintain long-term operation. The rotation accuracy is higher than that of ordinary bearings.
Transmission Configuration
The front, rear and lifting adopt precision grade linear slide rails, and cooperate with precision grade ball screws for precise positioning and linear motion.
Full Casting Design
The standard grinding machine spindle is equipped with a low-vibration high-horsepower motor, and the optional hydrostatic spindle has high damping and high anti-vibration characteristics, making the grinding process more stable. It is equipped with a direct-coupled oil-cooled motor for excellent driving efficiency.
