Window Liner / Wear Plate Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A precision-engineered plate component designed to protect the structural integrity of mill housing window openings by absorbing abrasive wear from metal chips, coolant, and debris during machining operations. It serves as a sacrificial barrier that extends the lifespan of the mill housing.

Working Principle

Acts as a sacrificial wear surface that absorbs abrasive contact from machining byproducts, distributing impact forces and preventing direct damage to the mill housing's structural surfaces through material erosion resistance.

Materials

High-carbon steel (AISI 1045/1050), hardened tool steel (AISI D2/D3), or tungsten carbide composite plates with surface hardness of 45-65 HRC.

Technical Parameters

Thickness 10-50 mm
Surface Finish Ra 1.6-3.2 μm
Surface Hardness 45-65 HRC
Flatness Tolerance ±0.1 mm/m
Mounting Hole Pattern Standardized grid (e.g., 50x50 mm)

Standards

ISO 2768, DIN 7168

Frequently Asked Questions

How often should window liners be replaced in mill housing?

Replacement frequency depends on operating conditions, typically every 6-24 months based on material abrasiveness, coolant type, and production volume.

Can wear plates be resurfaced instead of replaced?

Limited resurfacing is possible for certain materials, but replacement is generally recommended to maintain dimensional accuracy and protection effectiveness.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
