Grinding and polishing is one of the most important process in metallographic preparation. So grinding machine or polishing machine are always needed in metallurgy.
Features :
• This polishing machine is powder painted without toxicity
• Precise rotational balance will not deviate even highly pressed
• Steady machine design does not waver during operation
• Stable body design to prevent machine from shaking while in use.
• Designed with double waterproof lids, safe and easy grinding,
wich makes the workpiece unease to fall
• The main shaft is anti-leakage designed, which makes running smooth
• The replaceable grinding disc can be changed quickly
• Double stainless steel water pipes can be adjusted
• The sample is fixed to rotate, fast grinding surface is even.
• Noise level: below 55 decibels (close to machine for 1.5m).
• When current is overloaded, current output will be reduced automatically to protect motor.
• Grinding/polishing sizes can be set.
