FAQ
Q: What stone profiles can this machine process?
A: It can process mainstream styles including straight edge polishing, 45° bevel chamfering, front & back bright edges, anti-slip grooves, water retaining grooves and full side polishing. Special-shaped line profiles can also be customized with dedicated abrasives.
Q: Is it applicable to both granite and marble?
A: Absolutely yes. Equipped with frequency conversion speed regulation, it flexibly adjusts processing speed to suit hard granite and soft marble simply by replacing polishing pads of corresponding grain sizes.
Q: What is the working principle of automatic grinding head compensation?
A: The machine monitors pad wear in real time via current induction. When abrasives are worn out, the grinding heads automatically feed forward to maintain even pressing force stably with no manual adjustment needed, ensuring consistent polishing quality all the time.
Q: What is the power requirement of the machine?
A: The standard model adopts 380V three-phase industrial power with total power of 15KW. Different voltages and frequencies can be customized according to local power standards.
Q: How long is the warranty period?
A: We offer 12-month warranty and lifelong technical support.
Q: Can this machine perform grooving processing?
A: Yes. The No.1 grinding head can be directly fitted with grooving wheels. Grooving depth and width are freely adjustable via one-click parameter setting on the touch screen for easy processing of various functional grooves.
Q: What is the delivery lead time?
A: Standard delivery time is 30 days upon receipt of advance payment.
