Production Pain Points It Solves
Workshops processing thick cylindrical ring stock frequently struggle with two core issues when using general grinding equipment. First, low rigidity spindles produce uneven flatness after long runs, failing tight parallelism checks required for assembly. Second, limited table travel restricts how many cylindrical parts can be set per cycle, forcing constant re-fixturing that introduces thickness deviation across batches.
This cylindrical surface grinder is calibrated exclusively for cylindrical blanks ranging 18-50mm thick. Its separated motor layout and extended table travel cut manual repositioning work while locking in ultra-fine geometric tolerances without frequent parameter readjustment.
Measured Machining Precision Benchmarks
All tolerance data captured under consistent full-load production cycles. Minor variation may occur based on raw blank material hardness:
- Parallelism deviation: 0.005 mm
- Flatness tolerance: 0.005 mm
- Cross-batch thickness variance: 0.01 mm
- Achievable surface roughness: Ra 0.32 μm
Uniform dual-plane geometry eliminates uneven axial contact when cylindrical rings fit onto mating shafts, reducing vibration and premature wear in finished mechanical assemblies.
Segmented Hardware Parameter Breakdown
1. Machining Thickness Range and Travel Layout
Tailored for medium-thick cylindrical ring workpieces, fixed processing thickness window covers mainstream component sizes:
- Minimum blank machining thickness: 18 mm
- Maximum blank machining thickness: 50 mm
- Horizontal table travel range: 500 mm
- Vertical grinding head stroke: 120 mm
The 500mm extended table travel supports multi-piece fixture stacking, letting operators load multiple cylindrical blanks to finish in one continuous cycle. The 120mm vertical head stroke leaves clearance for custom ring fixture tooling, accommodating slight variations in blank outer diameter.
2. Reinforced Spindle and Micro Feed Control
- Main spindle shaft diameter: Φ100 mm
- Minimum incremental feed adjustment: 0.001 mm
The solid Φ100 spindle resists rotational deflection under steady cutting load, the core component maintaining consistent flatness on thick cylindrical surfaces. The 0.001mm micro feed step allows incremental stock removal: operators complete bulk rough grinding then switch to delicate finishing passes without re-clamping cylindrical blanks.
3. Independent Multi-Motor Drive System
Three dedicated motor groups handle separate machine motions to isolate cutting vibration and thermal load:
- Twin spindle drive motors: 15 kW each, deliver balanced torque for simultaneous dual-face grinding on thick cylindrical stock
- Dual grinding head feed motors: 1.8 kW each, regulate stable vertical travel speed for uniform stock removal
- Independent horizontal table feeding motor: 2.2 kW, maintains steady table movement during full batch cycles
Splitting drive functions prevents single motor overload during multi-shift operation, extending service life of core moving assemblies and cutting unplanned downtime.
Real-World Production Advantages
1. Optimized 18-50mm thickness window eliminates wasted grinding capacity when processing medium-thick cylindrical rings, speeding cycle times vs oversized general grinders.
2. 500mm long table travel raises single-cycle workpiece count, lowering labor spent on repeated clamping and alignment between batches.
3. Φ100 rigid spindle suppresses runout during continuous grinding, holding the tight 0.005mm flatness and parallelism tolerance critical for cylindrical transmission components.
4. Three independent motor sets disperse heat and vibration separately, avoiding geometric drift that ruins precision on thick cylindrical blanks over long production shifts.
5. Micro 0.001mm feed resolution unifies rough and fine finishing in one setup, removing the need for secondary polishing steps on finished cylindrical parts.
Client Common Questions
Q1: What types of workpieces match this cylindrical surface grinder best?
A: It targets medium-thickness cylindrical ring blanks such as transmission bearing sleeves, hydraulic sealing rings and motor magnetic ferrite cylinders that demand strict parallelism and flatness on two planar faces.
Q2: Why separate table feed, grinding head feed and spindle into independent motors?
A: Combined single-drive systems transfer vibration between table movement and spindle rotation, causing uneven surface marks on thick cylindrical stock. Segmented motors isolate each motion source to preserve consistent micron precision through back-to-back production runs.
Q3: Is this machine suited for continuous daily batch production of cylindrical parts?
A: Yes. The reinforced spindle structure and split power layout stabilize dimensional output during extended shifts. The long table travel also supports semi-automatic loading jig integration for high-volume cylindrical ring production lines.
