NC Tungsten Carbide Bar Chamfering Machine With position detection

Product introduction

The chamfering machine is a special designed machine for cylindrical chamfering

grinding of large-sized cemented carbide rods. The equipment uses the clamping

spindle and the precision air pressed chuck to push the rod forward and backward to

right position and to rotate the rods. The angle between the X axis and the clamping

axis is 45 ° , and the grinding wheel finish chamfering of the rod through the

synchronous movement of the X and Y axes. At the same time, through the automatic

feeding mechanism, the material is fed synchronously, and the finished rod is pushed

back in a straight line, so as to realize the full automation of the processing process.

NC Tungsten Carbide Bar Chamfering Machine with Position Detection: Revolutionizing Precision Grinding for Industrial Applications

Introduction

The NC Tungsten Carbide Bar Chamfering Machine represents a pinnacle of engineering innovation, specifically engineered for cylindrical chamfering grinding of large-sized cemented carbide rods. Combining German precision components with advanced automation, this machine delivers unmatched accuracy (±1°) and efficiency for industrial-scale operations. Ideal for sectors like tool manufacturing, aerospace, and automotive engineering, it streamlines the production of high-tolerance carbide components while eliminating manual intervention.

Core Technology & Operational Excellence

1. Precision Grinding Mechanism

• Utilizes a 45°-angled X-axis relative to the clamping axis, synchronized with Y-axis movements. This geometry ensures consistent 45° chamfers on rods ranging from Φ8–Φ20mm.
• German Schopperlin Precision Chucks (Φ8/Φ10/Φ12) provide zero-slip clamping, maintaining radial accuracy within 0.02–0.03mm during rotation.

1. Fully Automated Workflow

• Servo-Driven Feed System: An automatic feeding mechanism advances rods linearly (400mm max schedule) while the PLC-controlled spindle pushes finished rods backward, enabling uninterrupted batch processing.
• Position Detection Sensors: Real-time monitoring adjusts grinding depth (50–120mm length range), compensating for material inconsistencies.

1. Robust Construction

• Heavy-duty cast-iron frame (1350kg weight) dampens vibrations, while the Φ200×31.75×20mm grinding wheel ensures longevity under high-load operations.
• Oil-cooled servo motors (5kW total power) sustain table speeds of 3–23mm/min without thermal drift.
