Maintenance Of Turning Milling Compound CNC Machine Tool

1. Instructions for use and maintenance of ball screw of turn milling compound machine tool

● The ball screw is a moving pair of parts, which must be fully lubricated to avoid oil loss and dry friction damaging the ball screw. When the machine tool adopts large flow cooling, pay attention to increase the lubrication frequency and flow of the ball screw to avoid water rust of the screw.

● For ball screw, pay attention to avoid debris, dust, impurities and other particles entering the auxiliary working area of the screw, resulting in damage to the screw.

● Strictly prevent collision, resulting in displacement damage of ball screw nut returner, affecting accuracy and generating noise.

● Do not allow the nut to exceed the travel limit.

2. Maintenance instructions for motor of turn milling compound machine tool

● The main motor (variable frequency motor or two speed motor) and drive motor (stepping motor or servo motor) shall be protected from moisture. If the motor is flooded, it will cause phase to phase short circuit and burn the motor; The servo motor shall be protected from collision, which will cause damage to the encoder of the servo motor.

● When equipped with servo motor or variable frequency speed regulation, it can find out the cause of the alarm and the method to eliminate the alarm according to the alarm information (alarm number) of servo driver or frequency converter, or call the manufacturer directly.

● When using frequency conversion, after cutting off the AC power supply and before the indicator light of the digital operator of the AC motor driver goes out, it indicates that there is still high voltage inside the AC motor driver, which is very dangerous. Do not touch the internal circuit and parts and components, and operate after 5 minutes of power failure.

● When the machine tool is not used for a long time, the main power supply shall be cut off, and the machine tool shall run continuously for 2 ~ 3 hours at least once a month.

 

3. Maintenance instructions for spindle of turn milling compound machine tool

● In order to ensure the long-term smooth operation and service life of the spindle, please warm up the machine after handover with the machine to ensure the service life of the spindle

● When the temperature difference between spindle and bushing is too large, it is easy to burn out the spindle bearing The temperature of the oil cooler must be set according to the temperature in winter and summer

● The daily extreme speed operation time shall not exceed 1 / 4 of the daily processing time.

● It is recommended to maintain the spindle running speed at the normal running speed (85% of the spindle Zui high speed).

● The continuous operation time of the spindle under normal operation speed shall not exceed 8 hours. Every eight hours of spindle operation, the spindle needs to slow down to low speed for 1 hour.

● The outer ring of the main shaft is blown, and the pressure standard is set at 1.2kg/cm2-1.5kg/cm2.

● When the spindle is not equipped with a tool / tool handle, be more careful when blowing iron filings with an air gun. Iron filings powder / water cannot enter the conical hole of the spindle, which is easy to cause poor precision or even damage of the spindle.

● When the spindle of turn-milling compound machine tool is in normal use, the parts are guaranteed for 1 year and the bearings are guaranteed for 1600 / hr. Note: when running the spindle every day, you must first determine whether the air blowing of the outer ring of the spindle is normal.

Advantages and Applications of Rolling Machines

图片
Rolling machines , also known as roll forming machines, are a crucial component in the manufacturing and fabrication industries. These machines utilize a continuous bending process to shape metal sheets or strips into desired profiles. The process involves feeding the material through a series of rolls, which gradually shape it into the required form. Advantages of Using Rolling Machines Cost-Efficiency and Material Savings Rolling machines offer significant cost advantages over traditional fabrication methods. The continuous process reduces material wastage, leading to material savings. Moreover, the streamlined production process minimizes labor requirements, further reducing operational costs. Versatility in Material Selection One of the key advantages of rolling machines is their versatility in handling various materials. Whether you need to work with steel, aluminum, copper, or other alloys, a well-designed rolling machine can adapt to different material thicknesses and properties...

Introduction to Facing and Centering Machines: A Comprehensive Overview

图片
Facing and centering machines   are essential tools in the field of machining and manufacturing. They play a crucial role in achieving precise and accurate results by preparing workpieces for subsequent machining operations. This comprehensive overview will provide an introduction to facing and centering machines, including their functions, types, operation, and applications. Function of Facing and Centering Machines: Slanting Facing and centering machines  are primarily used to ensure the proper alignment and positioning of workpieces before machining. These machines perform two fundamental operations: Facing: The facing operation involves removing material from the surface of a workpiece to create a smooth, flat surface that is perpendicular to the rotational axis of the machine. This process helps achieve parallelism, flatness, and desired surface finishes. Centering: Centering refers to aligning the rotational axis of the workpiece with the spindle axis of the machine...
