Here are a few things to keep in mind when buying a grinding machine:
1. Workpiece specification and grinding wheel size: select the appropriate grinding machine size according to the expected workpiece specification to ensure that there is enough contact area. At the same time, consider the size of the grinding wheel that can be accommodated, which is related to machining accuracy, rigidity and machine stability.
2. Power and speed: The torque power of the spindle directly affects the grinding efficiency. For applications that require high material removal rates, a powerful grinding machine should be selected. In addition, it is important to adjust the rotational speed according to the needs of the workpiece.
3. Brand and quality: understand the basic knowledge of the brand, such as the stability of the fuselage, the origin of parts and components, and precision data. Make sure that the grinding machine you choose is suitable for your machining needs.
4. Test run and feel: bring the actual workpiece for test grinding and observe the working state of the machine tool. No vibration, low noise, light operation and stable up-and-down movement are the hallmarks of a high-quality grinding machine.
5. Legitimacy and invoice: check whether the enterprise is operating legally and can provide formal VAT invoices.
6. Delivery date and payment method: clarify the delivery time and agree on the payment method to ensure the smooth progress of the transaction.
7. Quality of key components: The quality of components in key parts is very important to the overall processing quality and stability.
8. Appearance wear and function test: check the appearance wear and tear of the machine tool and ask about its use history. During the trial operation, pay attention to whether the hydraulic table, stroke feed, spindle runout, etc. are normal.
When purchasing a grinding machine, taking these factors into account will help you choose the right equipment for your needs and consistent performance.
