The division of filter press manufacturing processes into distinct stages must consider the entire production system, not just individual surface treatments or specific operations. For instance, positioning datums often require precision machining during semi-finishing or even roughing stages, while drilling operations (typically rough machining) may occasionally appear in finishing stages.

Process Concentration vs. Dispersion
1.1 Process Concentration
Characterized by fewer operations with more extensive machining content per operation.

1.1.1 Advantages:

Enables high-efficiency dedicated equipment utilization including multi-tool/multi-edge machines, multi-spindle CNC equipment, and machining centers, leading to significant productivity gains.

Reduces total process steps, shortens technical routing, and simplifies production planning/organization.

Lowers resource requirements with fewer machines, reduced labor and floor space.

Minimizes workpiece repositioning, decreases auxiliary time, and enhances relative positional accuracy between surfaces.

1.1.2 Disadvantages:
5) Higher specialization costs with complex tooling systems, significant capital investment, and difficult product changeovers.

1.2 Process Dispersion
Features numerous operations with limited machining content per step.

1.2.1 Advantages:

Simplified equipment requirements with easier machine adjustment and lower operator skill thresholds.

Optimized cutting parameters for reduced machining time.

Enhanced production flexibility for faster product transition capability.

1.2.2 Disadvantages:
 Increased resource deployment requiring more machines/operators and larger production area.

Process Strategy Selection
The optimal approach depends on:
2.1 Production scale:
Small-batch: Typically concentrated.
Mass production: May employ either strategy including concentration via high-efficiency machines or dispersion for assembly line production.

2.2 Component characteristics:
Structural complexity.
Technical specifications.

Current industry trend shows progressive shift toward process concentration for modern manufacturing efficiency.

Note: Manufacturers should conduct comprehensive cost-benefit analysis when designing process flows.
