Manual Cylindrical Grinding Machine M1350

Primary product details

• Max. length ground (O.D): 1500 / 2000 / 3000 / 4000 mm (model dependent)
• Dia. Ground (O.D): 25–500 mm
• Center height: 270 mm

Key Features

• High Precision and Efficiency: Engineered to maintain tight roundness and surface finish tolerances; supports external cylindrical and tapered grinding with high repeatability on workpieces up to 4 m.
• Independent Drive System: Grinding wheel, oil pump, and coolant pump operate via separate motors to minimize mechanical interference and improve thermal stability and vibration control.
• Precision Grinding Wheel Compatibility: Compatible with CBN, ceramic, and conventional abrasive wheels. Optional dressing units available to maintain wheel condition.
• Stable Mechanical Structure: Bed and headstock constructed from high-quality cast iron, heat-treated and stress-relieved for superior rigidity and vibration damping.

Recommended Configurations

• Spindle and grinding wheel system: High-speed spindle / fixed-speed spindle motor / fixed or adjustable grinding wheel options
• Worktable and tailstock system: Manual tailstock adjustment / adjustable T-slot worktable
• Feed system: High-precision ball screws, linear guideways
• Cooling & lubrication: Coolant injection system, automatic lubrication system
• Clamping: Standard fixtures, pneumatic fixtures, U-shaped fixtures
• Optional accessories: Rotary chuck, centers, follow rest, measuring instruments, grinding wheel dressing fixture, HMI, protective covers, lighting and blower system

Application Case

• Client: Automotive component supplier (example)
• Component: Steel shaft for commercial vehicle transmission (φ80 mm × 3000 mm)
• Setup: M1350-3000 with CBN grinding wheel, magnetic chuck, and paper-filter coolant system
• Results: Roundness Accuracy ≤ 0.004 mm; Surface Finish Ra ≤ 0.6 μm
• Operator Feedback: "The M13 grinder provides excellent stability during long part grinding, and its simple, robust design makes it perfect for daily production runs."
