The external spray-type micro-lubrication is easy to install, as long as it does not affect the movement of machining and other components to meet the requirements.
Internal cold type micro-lubrication is that the lubricant is sprayed into the cutting area in the form of suspended oil mist particles. The key to this is to maintain the reliable flow of suspended particles. Therefore, the design of the machine tool should ensure the optimal transport and passage of suspended particles. The seal is reliable, and the matching jig and cutting tool are matched to ensure that the lubricant mist particles reach the cutting area.
Vertical lathes can be used either with internal cold type micro-lubrication or external cold type micro-lubrication. According to the specific conditions of the machine with a small amount of lubrication system. Many vertical vehicles do not have internal cooling channels. Therefore, peripheral nozzles are often used to convey MQL oil mist to lubricate the cutting area of ​​cutting tools. The following is a brief description of its features:
When the lubricating device receives the processing signal, the injection system enters the working state, and the lubricating oil is supplied by the micro-pneumatic lubrication pump at the set frequency, and the sprayed oil mist particles are formed at the nozzle to reach the surface of the workpiece. The compressed air at each lubrication point maintains the normal state. When the machining is completed, the lubrication device stops working at the same time. The adjustment of the oil supply frequency is based on the formation of an oil film in the injection area.
The low level monitoring of the system can give an alarm when the oil level is low, prompting the maintenance personnel of the lubrication system to require fueling, and the low level alarm signal can be linked with the machine alarm system.
External injection type lubrication adopts precise metering technology and saves oil consumption. Reliable oil is sprayed on the surface of the workpiece and the cutting tool in the form of tiny oil mist particles at the terminal to form a lubricant film.
1. Jet-type lubrication can save a lot of oil consumption without wasting.
2. Low consumption of lubricant medium, measured in ml/h units;
3, accurate measurement and accurate supply of oil;
4. The system has few moving parts, and the operation and maintenance are small;
5, oil and gas pipeline layout is simple, easy to install and maintain.
The main technical feature as follows:
(1) This product combined the controller and thyristor module,the connection of the users is simple and easy.Prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.
(2) Realize the best optimization of AC voltage control curve and DC voltage control curve.
(3) With the function of inching during operation, realize the accuracy.
(4) The electronic components adopt the imported industrial grade chip, on the control panel directly with power supply and direction indicator light.
(5) Adopt the coating treatment on the printed circuit board,enhance the dust prevention and anti-condensation capacity of the circuit board.
Application of micro-lubrication on vertical lathes
Micro-lubrication is applied to vertical lathes with two types of external spray and internal cooling.
