Product Description

Ultra-Heavy-Duty Precision Chuck System (350/360/450 Series) -  Product Introduction

This series of high-performance chucks (350/360/450 specifications) is tailored for large-scale, heavy-load laser tube cutting machines, covering circular/square pipes, I-beams, channel steel, and special profiles. With ultra-high load capacity (600-1500kg), ±0.05mm precision, and multi-profile adaptability, it meets the core needs of heavy-duty industrial scenarios such as large steel structures, heavy machinery manufacturing, and infrastructure projects.

Core Selling Points
Ultra-Heavy Load Bearing: 360-series heavy-duty square chucks support up to 1500kg total load, 450-series circular chucks handle 1100kg, ideal for thick-walled large-diameter pipes and heavy profiles.Wide Profile Compatibility: Covers round pipes(φ10-φ450mm), square pipes (250x250-360x360mm), I-beam/channel steel (≤32#), angle steel (≤22#), and special profiles (circumscribed circle <φ450/=360x360mm).
Industrial-Grade Precision: ±0.05mm clamping accuracy (350/360 series) and ±0.1mm (450 series), ensuring stable cutting quality for high-precision large-scale components.
High-Stability Drive System: Front chuck (4kW high inertia) + rear chuck (3kW high inertia) + 10:1 flange ratio, minimizing vibration during high-speed rotation of heavy loads.
Dedicated Model Configuration: Clear classification of circular/square/heavy-duty types (MK/KDN series), matching
different processing needs without secondary modification.

Application Scenarios
350 Series: Medium-heavy industrial processing (e.g., φ350mm thick-walled carbon steel pipes, 250x250mm square tubes for mechanical frames). 360 Series (Precision/Standard): Large-size precision components (e.g., 360x360mm square tubes for steel structures, 22# angle steel for bridges). 360 Heavy-Duty Series: Ultra-heavy load production (e.g., 1500kg super-thick-walled pipes, large I-beams for industrial workshops). 450 Series: Super-large diameter pipe processing (e.g., φ450mm municipal engineering pipes, 32# channel steel for heavy machinery)
