M7650B Horizontal Spindle Surface Grinder
Who It's For
This machine targets mid-sized precision component workshops, miniature bearing manufacturers and automotive sealing part producers. Facilities running mixed low-to-medium batches of thin circular metal blanks will benefit most, especially teams aiming to combine rough grinding and fine finishing on a single unit without expanding floor space.
Core Performance
All tolerance data is collected under continuous full-load operation; minor variations depend on workpiece material hardness and geometry:
- Parallelism deviation: 0.002 mm
- Flatness tolerance: 0.003 mm
- Batch thickness variation: 0.01 mm
- Surface roughness finish: Ra 0.32 μm
Consistent planar geometry reduces assembly gaps and secondary manual polishing work for small mechanical parts.

Operational Benefits
1. Horizontal spindle design delivers full uniform contact across thin blanks, avoiding surface warping common with vertical spindle models on delicate small workpieces.
2. Two independent adjustable speed ranges support both fast stock removal and ultra-fine finishing within one fixture setup, cutting part transfer time between processes.
3. Synchronized dual motor layout evenly disperses operating vibration, stabilizing micron-level accuracy through multi-hour daily production.
4. Compact 5-ton cast frame fits standard factory flooring without reinforced foundation requirements, simplifying production line layout planning and installation.
FAQ
Q1: What types of workpieces is this horizontal spindle grinder designed to process?
A: It matches thin, small-diameter circular blanks including miniature bearing races, metal sealing washers and compact hydraulic valve discs that demand strict flatness and parallelism.
Q2: Is it possible to switch between rough grinding and precision finishing without retooling?
A: Yes. The wide adjustable feed speed range lets operators tune cutting depth freely, completing both rough stock removal and surface refinement in a single machine cycle.
Q3: Does the compact frame compromise long-term machining stability?
A: The solid one-piece cast base suppresses micro-vibration during continuous operation. Combined with balanced twin motor drive, it retains consistent geometric tolerance through full daily production shifts.
