When you plan to purchase a metal-working surface grinding machine, you will have many questions about accuracy, performance, configuration and after-sales service. Knowing these key points will help you select the most suitable grinding equipment for your workshop.
1. What surface finish and flatness accuracy can this surface grinder achieve?
Accuracy is always the top concern for metal processors. Most buyers ask about flatness tolerance, parallelism and surface roughness Ra value. For precision mold steel parts, many customers expect Ra 0.4-0.8μm finish with good flatness over the full workpiece.
2. What is the maximum workpiece size the machine can process?
Customers need to confirm the table travel, magnetic chuck dimension and maximum grinding height. It is very important to check whether your parts can fit within the working range before ordering.
3. What brand are the spindle bearings and servo motors?
Spindle quality directly decides long-term stability. Buyers often inquire about motor power, spindle speed and main component brands. High‑quality bearings can reduce vibration and extend machine service life.
4. Can this grinder process stainless steel, alloy steel and tungsten steel?
Different metal materials require proper grinding wheels and parameters. Many clients want to know if the machine works for mold steel, carbon steel, hard‑alloy workpieces, and whether CBN or diamond wheels are supported.
5. Is it manual, hydraulic or CNC automatic feed?
Work‑table movement mode is another hot question. Hydraulic surface grinders are popular for mass production, while manual models fit small‑batch jobs. CNC grinders can realize automatic down‑feed and wheel dressing.
6. What voltage does the machine support? Can it match our local power supply?
For overseas buyers, power compatibility is essential. They frequently ask about 50Hz / 60Hz, 220V or 380V customized voltage to avoid installation problems.
7. What is included in the standard package?
Common accessories questions cover magnetic chuck, grinding wheel, flange, wheel dresser and tool kit. Clients also check optional attachments like dust cover, oil mist collector and fixture for non‑magnetic workpieces.
8. What about warranty and after‑sales support?
Nearly every customer cares about warranty period, spare parts supply, English operation manual and remote technical support. Reliable after‑sales service reduces long‑term operation risks.
