The high speed CNC machining center has large sliding contact surface of hard rail, good rigidity, strong seismic capacity and strong load-bearing capacity, suitable for heavy load cutting.
Hard rail belongs to dry friction, because of the large contact surface, so that the friction resistance is also large, the movement speed cannot be too fast.
Fengyuan hardware products factory can manufacture metal mold and plastic mold, in the mold manufacturing process is often used in high-speed CNC processing.
At the same time, it is easy to creep and there is a gap on the moving surface, which will lead to machining error.
The maintenance of the machine tool track is the top priority. Once the track is not sufficiently lubricated, it will cause the track to burn or wear transition, which is fatal to the accuracy of the machine tool.
The application of hard rails is suitable for heavy cutting, large molds, high hardness workpieces, and workpieces with general accuracy requirements.
At present, many machine tools run very fast, especially the space speed, which is largely dependent on the track.
The line rail can reach zero clearance and high precision after the pretreatment.
In terms of service life, line rails are much higher than hard rails.
The line rail bearing cutting force is smaller than the hard rail, just for the hard rail, in fact, now many machine tool line rail has greatly improved its bearing capacity.
The application of wire rail is suitable for high speed machine, it can be used for high speed cutting, suitable for processing products and small precision moulds.
More precision machining centers today use wire rails.
Cutting fluid is a kind of use in the process of metal cutting, cutting, grinding, used for lubrication and cooling cutting tool and the machined part liquid used in industry, cutting fluid by a variety of functional additives scientifically compound compatibility, and at the same time have good cooling performance, lubrication performance, rust resistance, degreasing cleaning, anti-corrosion, easy to dilute characteristics.
The main research contents of this paper are as follows :(1) establish the mechanical model of vertical machining center column, describe the calculation basis of cutting force under typical working conditions, analyze the load conditions of the column under various additional working conditions and the boundary conditions of different working conditions, so as to provide basic conditions for the analysis and design of the column structure.
It overcomes the defects of traditional soap-based emulsion, such as easy smell in summer, hard dilution in winter and poor anti-rust effect, and has no adverse effect on lathe paint. It is suitable for cutting and grinding ferrous metals, and belongs to the current grinding products.
Each index of cutting fluid is better than saponified oil, it has good cooling, cleaning, rust prevention and other characteristics, and has non-toxic, tasteless, no erosion to human body, no corrosion to equipment, no pollution to the environment and other characteristics.
