How Does an Ordinary CNC Lathe Transform High-quality Machinery?

If the ordinary lathes used and the lathes used for a long time are not modified, only new CNC turning lathes are purchased, which will increase the cost of equipment for many manufacturers. Therefore, it is the only way for manufacturers to carry out numerical control transformation on ordinary lathes and lathes that have been used for a long time.

Since the transformation of CNC turning lathes is complicated and messy for the transformation manufacturers, how to carry out quality control on the transformed CNC turning lathes is a problem that we have always needed to discuss. Here we will talk about how to carry out the quality control of the transformed CNC turning lathes.

Ordinary lathe CNC transformation is divided into new machine transformation and old machine transformation. The new machine transformation is that the user purchases an ordinary lathe or an ordinary optical machine (referring to a lathe with only a bedside box and vertical and horizontal guide rails), and the transformation manufacturers carry out numerical control transformation according to their requirements.

Retrofitting of old machines means that the user refurbishes the ordinary lathes or CNC turning lathes that have been used and performs numerical control transformation. Among them, the transformation of old machines includes the transformation of overhaul lathes and the transformation of old machine parts of users.

Here is a brief discussion on the quality control method, focus on control points and inspection process of the transformation of CNC turning lathes in terms of machinery.

1. Both the new machine transformation and the old machine overhaul CNC turning lathe transformation must undergo the same transformation as follows:

(1) Replace the X-axis, Z-axis screw, bearing and motor.

(2) Add electric tool post and spindle encoder.

(3) Increase the driving device of the axial motor, limit the limit switch of the running process, install the frequency converter (customer needs) and the electrical parts required for processing and safety.

(4) Scraping of the support surfaces at both ends of the X-axis and Z-axis, the scraping of the ball screw sub-bracket and the saddle, and the scraping of the bed and the saddle guide rail pair.

(5) Add protective facilities as needed, such as protective covers for screw rods in all directions, safety doors, and protective devices for travel switches.

2. The difference between the new machine transformation and the old machine overhaul CNC turning lathe transformation:

(1) The main shaft and tailstock of the new machine have not been modified, and the main shaft and tailstock do not need to be rebuilt.

(2) The guide rail of the old machine overhaul lathe has been worn out due to long-term use. In order to ensure that it can continue to be used for a long time without deformation after the overhaul, it must go through the quenching process, and then grind the guide rail. After grinding the guide rail, the hardness of the guide rail must be ≥ HRC47.

(3) The old machine overhaul lathe should modify and adjust the spindle part and tailstock part according to the customer's needs.
