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.
Flat face mask machine accessories, embossing shaft, press wheel, mask machine roller, roller
The roller is the main part of the rolling mill. It is subject to a certain impact during actual use, and the surface is rubbed by high-speed, high-temperature red steel. The surface is required to have good abrasion resistance, and at the same time, it must have sufficient toughness to prevent it from being broken by impact.
KN95 Mask Machine Roller, Stamping Shaft and Press Wheel
1. The embossing roller cart of the mask machine is made of seamless steel pipe, and then processed by CNC. Processing is divided into turning, milling and welding.
The milling cutter directly mills the groove in layers, but it needs to use the additional fourth axis of the machining center or the C axis function of the turning center to achieve. This article uses a turning center machine tool. The focusing tube was discovered after being processed with a simple fixture. Because the groove is processed through the wall and the groove shape is longer, the axial clamping is only used, and the width of the groove cannot be guaranteed due to the deformation of the clamping during processing.
