As a kind of integrated transfer machine, the spindle of hard rail CNC machine tool is a unit structure, and the main servo motor can achieve a higher speed. The workpiece is installed with hydraulic chuck, which makes the installation more convenient, higher precision and less effort.

The main shaft bearing structure adopts a total of 5 angular contact bearings in front 3 and after 2, which is both high speed and high rigidity. The machine adopts 30° inclined sliding saddle, linear guide rail, strong rigidity, fast feed and easy chip removal. X, Z screw are arranged in the middle of the drag plate, the drag plate uniform force, smooth movement, fast speed.

Any mechanical equipment is in need of maintenance, the same is true of hard rail CNC machine tools, machine tools occupy an important position in metal processing, the machine tool maintenance in order to play the ideal benefit in production. For the maintenance of CNC machine tools, machine lubrication is indispensable. Lubricating oil can not only reduce the friction of the machine, but also cool down, seal leakage, prevent rust, shock buffering and cleaning and other functions, increase the service life of the machine tool, all kinds of benefits show that the role of lubrication maintenance is great.

There are many ways of machine lubrication, the common are manual refueling lubrication, drop oil lubrication, oil rope lubrication, oil pad lubrication, self-priming lubrication, centrifugal lubrication, oil bath lubrication, oil ring lubrication, splash lubrication, scraper lubrication, roller lubrication, jet lubrication manual pump oil lubrication, pressure circulation lubrication, automatic timing quantitative lubrication, oil mist lubrication and so on.

integrated transfer machine lubrication precautions:

1, the main parts in the machine tool serialization degree is high, such as plain bearings, rolling bearings, gears, worm gear pair, rolling and sliding guide rail, spiral transmission pair (screw nut pair), clutch, hydraulic system, CAM, etc., lubrication conditions are different.

2, the use of the machine tool environmental conditions: hard rail CNC machine tools are usually installed in the indoor environment, the summer ambient temperature is 40 ° C, winter temperature below 0 ° C when the heating method is taken, so that the ambient temperature is higher than 5-10 ° C. However, due to the high precision requirements and high degree of automation of many machine tools, the requirements for the viscosity of lubricating oil, oxidation resistance (service life) and oil cleanliness are stricter.

3, the working conditions of the machine tool: different types of different specifications and sizes of the machine tool, even in the same machine tool due to the different conditions of the workpiece, the working conditions are very different. Requirements for lubrication vary.

4, the adaptability of lubricating oil and lubricating coolant, rubber seals, paint materials, etc. : in most machine tools, lubricating coolant is used. In lubricating oil, it is often mixed with coolant to emulsify and deteriorate the oil, rust the parts, etc., so that the rubber seals expand and deform, and the paint coating on the surface of the parts bubbles and spalling.

Therefore, consider the adaptability of oil products and lubricating coolants, rubber seals, paint materials, and prevent oil leakage. In particular, with the increase in the degree of automation of hard rail CNC machine tools, lubrication/cooling universal oil is used on some automation and CNC machine tools, which can be used as lubricating oil or lubricating coolant.
