How to maintain the large cnc turning?

May 28, 2018


Turning is Cnc lathe machine , lathe processing,Large cnc machine is a part of mechanical processing.Lathe machining mainly USES turning tool to turn the rotating workpiece.Drilling bit, reaming drill, reamer, tap tap, die and knurling tool can also be used in the lathe.Big lathe machine are mainly used for the processing of shafts, disks, sleeves and other workpieces with rotating surfaces. They are the most widely used machine tools in machinery manufacturing and repair plants.

 

 

Process feature of Used cnc machines

1. Easy to ensure the position accuracy of all machining surfaces of the workpiece

A for example, easy to ensure coaxial requirements

The rotary axis is the spindle axis of the lathe

The rotating axis is the central connection between the two centers

B is easy to ensure that the vertical degree of the end face and axis requires the guide rail of the horizontal slide plate and the vertical degree of the rotating axis of the workpiece

2. The smooth cutting process avoids the inertia force and impact force, and allows large cutting amount and high-speed cutting, which is conducive to productivity improvement.

3. Suitable for precision machining of non-ferrous metal parts

The surface roughness of non-ferrous metal parts requires a small Ra value, which is not suitable for grinding.High quality can be achieved when diamond tool is used for fine car.

4. Simple tool

Turning tool manufacturing, cutting and installation are more convenient.

 

 Maintenance of Cnc milling machine

1. Matters needing attention when mounting and correcting workpieces

Before installing the workpiece, it is necessary to remove impurities such as carbon in the workpiece sand and mud, remove impurities and insert them into the sliding surface of the towing plate, so as to aggravate the soft wear or "bite" guide rail.

In the clamping and correcting some school large size, complicated shape and the clamping and product of minor artifacts, should be placed on the surface of the workpiece under the lathe bed in advance of a wooden bed plate, or loose with press plunger to resist the workpiece at the same time, to prevent it falls bad lathe, such as found that the position of the workpiece is not correct or skew, hitting of avoid by all means, so as not to affect the precision of lathe spindle, must first to grip, linking piece or plunger slightly loosen, then correction step by step.

 

2. Installation of tools and tools

Tools and tools should not be placed on the bed to avoid damaging the guide rail.Cover the bed cover if necessary and place the tool and tool on the bed cover.

(1) when sanding the workpiece, cover the bed surface under the workpiece with a bed cover plate or paper;After the sand is clear, clean the bed carefully.

(2) in the cast iron work of the vehicle, the rail cover shall be installed on the choke plate, and at the same time, the lubricating oil on a section of the bed surface where the chip can be sprayed.

(3) when not in use, the cleaning and maintenance work of the lathe must be done to prevent chips, sand particles or impurities from entering the sliding surface of the guide rail of the lathe, and "bite" the guide rail or aggravate its wear.

(4) before using the cooling lubricant, it is necessary to remove the garbage in the guide rail of the lathe and the plate of the cooling lubricant;After use, dry the cooling lubricant on the guide rail and add mechanical lubrication.
