Paralled surface grinding machine — main view

Luoyang Songju is pleased to announce the successful shipment of a paralled surface grinding machine to our valued customer. This precision grinding solution is engineered for high-accuracy parallel face grinding of bearing components and industrial round parts.

Machine Overview

The paralled surface grinding machine is a specialized piece of equipment designed for grinding two parallel end faces simultaneously. It is primarily used in the bearing manufacturing industry for processing the inner and outer rings of small and medium-sized bearings. Beyond bearing applications, the machine excels at grinding piston rings, valve seats, valve plates, and various other round components that require precise parallel end faces.

This machine leverages a dual-face grinding principle that ensures both end faces are ground simultaneously under identical conditions. This simultaneous processing guarantees exceptional parallelism and uniform thickness across the entire workpiece — a critical quality requirement for high-performance bearing assemblies.

Technical Specifications

The machine delivers outstanding precision across all workpiece sizes. Below are the key performance specifications verified during factory acceptance testing prior to shipment:

Parameter Workpiece Diameter Specification
Parallelism ≤ 50 mm 0.002 mm
Parallelism 50 – 100 mm 0.004 mm
Parallelism 100 – 180 mm 0.006 mm
Thickness Error All sizes 0.02 mm
Surface Roughness All sizes Ra 0.32

Quality Assurance

All specifications were validated through rigorous factory acceptance testing prior to shipment. Each machine undergoes a comprehensive inspection protocol including parallelism measurement, thickness uniformity verification, and surface finish analysis using calibrated metrology equipment traceable to national standards.

Applications

This paralled surface grinding machine is ideally suited for manufacturers producing:

  • Bearing rings — inner and outer ring end face grinding for small and medium-sized bearings
  • Piston rings — achieving precise parallelism required for combustion sealing
  • Valve seats — ensuring flat, parallel mating surfaces for leak-free operation
  • Valve plates — high-precision grinding for compressor and pump components
  • General round parts — any circular component requiring parallel end faces with tight tolerances

Shipment & Delivery

The machine has been carefully packaged with moisture-proof protection, securely fastened to a reinforced pallet, and dispatched via our trusted logistics partners. Full shipping documentation, installation manuals, and operation guides accompany the shipment to ensure smooth installation and commissioning at the customer's facility.

As with all Luoyang Songju equipment, this machine is backed by our comprehensive after-sales support, including remote technical assistance and on-site commissioning services as required.
