Honing

Product catalog summary

Introduction
PCI-SCEMM presents an innovative honing process designed for machining centers, specifically targeting the finishing operations of cylinder blocks using standard horizontal CNC machines. This process leverages PCI's extensive experience in traditional honing and fine boring.

Expertise and Service
The document highlights PCI's expertise in fine boring and honing, emphasizing a single contact approach. Key features include numerical expansion with continuous drive and wear compensation, ensuring precision in fine boring with specified diameters (ISO code) and cutting edge retraction to avoid striking the liner.

Process Overview

Historic Process: Suitable for production over 300,000 units per year (KUPY) but lacks flexibility and requires specific honing skills.
Standard Process: Combines machining centers with honing machines, suitable for production under 200,000 KUPY. It offers an optimized honing process with reduced tool and abrasive consumption, flexibility, and standard machine benefits like spare parts and standard skills.
PCI Honing: Utilizes only a machining center with one clamping fixture, eliminating misalignment issues. This process integrates fine boring and honing in one setup, providing a single point of contact for operations.

Technical Specifications
The document details the technical specifications of the PCI honing technology, featuring the HSK100 PCI Spindle, which is ideal for cylinder block finishing due to its high torque and rigidity. It includes an automatic tool changer for honing and fine boring tools, a U Axis for expansion-driven tools, and a honing cycle that ensures a perfect cross-hatch pattern on finished surfaces. Key specifications include:

Max speed: 12,000 RPM
Power: 40 - 65 kW (S1 - S6)
Torque: 200 - 310 Nm (S1 - S6)
Spindle taper: HSK100-A
Lubrication: Lifetime grease

Conclusion
PCI-SCEMM's honing process offers a streamlined and efficient solution for cylinder block finishing, combining fine boring and honing in a single machining center setup, enhancing flexibility, and reducing operational complexity.
