FAQs
Common Questions About Bridge Single Head Stone Polisher
What is a bridge single head stone polisher?
Bridge single head stone polisher uses 15KW motor with automated grinding head for precise stone surface finishing. The bridge structure provides stable platform for processing granite, marble, and natural stone slabs up to 3000×2000×120mm. PLC programming controls longitudinal, transverse, and wave grinding patterns automatically adjusting pressure and speed.
How does bridge granite polishing equipment work?
Granite polishing equipment operates through air cylinder-controlled grinding head with diamond tools rotating at 560 r/min. System automatically adjusts grinding patterns based on stone hardness, using 0.35-0.5 MPa pressure for optimal material removal. Integrated water cooling at 4m³/h prevents overheating while maintaining surface quality.
What materials can bridge stone polishing machines process?
Stone polishing machines handle granite, marble, limestone, travertine, and quartzite materials efficiently. Different stone types require specific grinding parameters - granite needs higher pressure, marble requires gentler speeds. Universal design accommodates varying hardness levels from soft limestone to dense quartzite through programmable settings.
What's the difference between single-head and multi-head polishers?
Single-head polishers excel at precision work and custom shapes, while multi-head systems optimize high-volume production. Bridge single head offers maximum flexibility for varied thicknesses and specialty applications. Multi-head machines suit continuous slab production, single-head handles monuments, countertops, and architectural elements requiring individual attention.
What are the technical specifications of the Bridge Single Head Stone Polisher?
QDMJ series offers four models: 900/1200/1800mm standard models and 2000mm heavy-duty version. All models feature 15KW main motor, 560 r/min grinding speed, and 3000mm processing length. Feed rates range 0-4300mm/min longitudinal and 0-5600mm/min transverse with 3-120mm thickness capacity.
What applications suit Single Head Stone Polisher best?
Machine excels at tombstone production, kitchen countertops, bathroom vanities, and architectural panels requiring precision finishing. Ideal for custom projects and medium-volume production where surface quality matters more than speed. Perfect for monuments, specialty stones, and detailed work needing individual attention.
What maintenance and support are DINOSAW provided for Single Head Stone Polisher?
Regular maintenance includes grinding head inspection, water system cleaning, and component lubrication every 200 operating hours. DINOSAW provides comprehensive technical support, spare parts availability, and installation training. Robust design minimizes downtime with easily accessible service points and 24/7 technical assistance.
How does pricing compare to alternatives?
Bridge single head offers lower initial investment than multi-head systems while delivering superior flexibility for custom applications. Operating costs average 30% less than comparable equipment due to efficient water usage and reduced maintenance. ROI typically achieved within 18-24 months for specialized stone processing operations.
