High-Precision Grinding Manufacturer: Used High-Precision Surface Grinder with ASD Control Panel

High-precision grinding A second-hand high-precision surface grinder is a type of grinding machine. It primarily uses a rotating abrasive wheel to polish workpieces, achieving the required surface flatness. Depending on the shape of the worktable, it can be classified into two types: rectangular‑table and circular‑table models. So, are you familiar with how to operate the ASD control panel of a high‑precision surface grinder and what specific maintenance procedures should be followed? In the following discussion, a manufacturer of precision grinders will explain the proper use of the ASD control panel on second-hand high‑precision surface grinders.

High-precision grinding The manufacturer introduces the ASD control panel for high-precision surface grinders:

1. The vertical movement of the Y-axis is driven by a high-speed lifting mechanism powered by an AC motor, while a separate stepper motor performs precise downward machining and grinding, providing a slow, controlled lowering motion; the position feedback is rapidly re-validated via an encoder.

2. Displays the position of the spindle head relative to the upward/downward value window. Panel settings allow you to configure the grinding point, coarse‑grinding feed rate, fine‑grinding point, fine‑grinding feed rate, target point, pick‑up point, intermittent spark grinding, and dry grinding.

3. The Z-axis saddle features automatic lateral feed, driven by a DC servo motor; it supports both internal and external inch‑type grinding, continuous-feed polishing, and four‑wheel trimming, with speed adjustable via stepless variable‑speed control on the panel.

4. The four‑wheel automatic feed allows for a minimum increment of 0.001; this model can be programmed to set the rise point, start point, fine adjustment step, target point, four‑wheel rebound point, and includes digital display and a button panel for learning and operation.

High-precision grinding Manufacturer’s tips on maintenance precautions for high-precision surface grinders:

1. Adjust the grinding wheel balance before grinding.

2. Select a grinding wheel carefully based on the material and its hardness.

3. Apply a thin layer of oil to the spindle end and the wheel flange to prevent rusting.

4. Pay attention to the spindle’s direction of rotation.

5. The use of cleaning tools and machinery is prohibited.

6. Check whether the oil passage in the oil sight glass is unobstructed.

Surface grinding and polishing are virtually equivalent to grinding hard‑alloy blanks and hard steels, and are typically divided into several stages: pre‑polishing treatment, rough grinding, semi‑precision grinding, and fine grinding. However, due to the exceptional hardness of cemented carbide materials, micro‑polishing machines must employ different abrasive selections. In this regard, precision‑grinding manufacturers recommend that pre‑polishing be carried out using green silicon carbide wheels or tungsten carbide wheels. During rough grinding, polishing powders made from boron carbide are used. Semi‑precision and precision grinding, on the other hand, are performed with diamond polishing powders.

Surface polishing can be performed in various ways as a preparatory step before grinding hard‑alloy workpieces. For example, conventional grinding, electrochemical grinding, abrasive‑free grinding, and ultrasonic machining can all serve this pre‑processing purpose. Among these, grinding combined with boron carbide abrasives is often chosen for rough grinding. However, due to its relatively low material removal rate, boron carbide abrasive powders are frequently employed in large‑scale production to finish coarse surfaces.

The above is a detailed introduction to the user manual for the ASD control panel of used high-precision surface grinders. The manufacturer of precision grinding equipment hopes this information will be helpful to you.
