In turning processing components (aluminum, stainless steel, copper, titanium, alloy), especially for finishing, how to choose a tool? Summary of experience of CNC masters:
1. First, determine the entering angle of the tool
In a blink of an eye, I have been operating CNC lathes for more than ten years, and have accumulated some machining skills and experience of CNC lathes. Including turning of different materials (stainless steel, aluminum, copper carbon steel, titanium, cemented carbide, etc.). Due to frequent replacement of processed parts and limited factory conditions, for ten years we have been programming ourselves, setting tools ourselves, debugging and finishing parts processing ourselves. In summary, the operating skills are divided into the following points.
The processing technology of CNC lathe is similar to that of ordinary lathe. However, because the CNC lathe is a one-time clamping, continuous and automatic processing to complete all turning processes. Therefore, the following aspects should be paid attention to:
1. Reasonable choice of cutting amount
Four kinds of standard threads can be turned on the CNC lathe: metric, inch, modular thread and diameter controlled thread. No matter what kind of thread is turning, a strict movement relationship must be maintained between the lathe spindle and the tool: That is, every time the spindle rotates (that is, the workpiece rotates once), the tool should move evenly by a lead distance. The following analysis of ordinary threads will strengthen the understanding of ordinary threads in order to better process ordinary threads.
In the early years, the cutting force test during high-speed turning was carried out. As shown in Figure 1, when turning 45 steel (normalizing, HB187), when the turning speed is increased from 100m/min to 270m/min, the main turning force is reduced by about 7%. As shown in Figure 2, when turning cast aluminum alloy ZL10 (HB45), when the turning speed is increased from 100m/min to 720m/min, the main turning force is reduced by about 50%.
machining of revolving parts
The development of turning center has a considerable part of rotating parts (someone estimates that it accounts for about 1/2). In addition to turning, operations such as milling, drilling, and tapping are also required. In addition, the processing time for each process of the rotating body is relatively short. Therefore, it is urgent to perform multi-process compound processing on the rotating body under one clamping on a machine tool, and finally a compound turning center was developed in the 1970s.
This article analyzes the process settings for turning hardened steel, high temperature alloy, titanium alloy, chilled cast iron, and thermal spray material parts. And the characteristics of these difficult-to-cut materials, cutting quantities, turning fluids, and turning tools.
This article introduces several CNC turning technologies for very specification materials: products include turning of soft rubber, turning of grinding wheels, turning of cemented carbide, turning of ceramics, turning of composite materials. For different materials, choose different tool materials, tool geometric parameters, cutting amount, and cutting fluid.
