Maintenance of CNC horizontal drilling and milling machine

Supertime Technology

WZ series CNC horizontal drilling and milling machine, also known as CNC deep hole drilling, pipe and plate deep hole drilling. According to the function, structure and system of CNC horizontal drilling and milling machine, the contents and rules of maintenance are also different. Specific should refer to the specification requirements, formulate and establish the necessary regular, grading and maintenance system. Here are some common, common daily maintenance points.

I.Maintenance of mechanical parts of CNC horizontal drilling and milling machine

A.The maintenance of the main drive chain

1. Adjust the tightness of the spindle drive belt regularly to prevent the phenomenon of loss caused by slipping;
2. Check the lubricating oil tank of the main shaft, adjust the temperature range, add oil in time, and clean the filter;
3. After the long time use of the tool in the spindle, the gap will be produced, which will affect the clamping of the tool, and the displacement of the piston of the hydraulic cylinder should be adjusted in time

B.The maintenance of ball screw pair

1. Regularly check and adjust the axial clearance of the screw thread pair to ensure the accuracy of reverse transmission and axial stiffness;
2. The regular check screw and bed connection is loose.

II. Maintenance of CNC system of CNC horizontal drilling and milling machine

A.To strictly abide by the rules of operation and maintenance system;

B.It should be as little as possible to open CNC deep hole drilling numerical control cabinet and electric cabinet doors, in the machining workshop in the air will generally have oil mist, dust and metal powder, once they fall the circuit board or electronic devices within the NC system, easily lead to decreased insulation resistance between components and circuit components, and even lead to plate damage.

C.Some users in the summer in order to make the numerical control system can overload the long-term work, take the door to open the numerical control cabinet to heat, this is an extremely undesirable method, which will eventually lead to the acceleration of the numerical control system damage.

D.The ventilation system cleaning regularly drilling numerical control cabinet, each cooling fan to check whether the normal numerical control cabinet.

E.Check once every six months or a quarter of the air duct filter clogging phenomenon, if the filter is too much dust accumulated on the Internet, do not clean up, will cause the temperature is too high.

F.The regular inspection of DC motor brush drilling and replace the DC motor brush wear transition, will affect the performance of the motor, and even cause motor damage. To this end, the motor brush should conduct regular inspection and replacement.

How to choose the angle notching machine?

Supertime Technology

Hydraulic angle notching machine: steel tower processing auxiliary equipment designed and manufactured according to the processing technology of the iron tower.

The machine used for cut angles, to solve the problem of collision angle and other components. Cutting angles including small angle cutting, cutting angle, cutting the body.

According to the working force of oil cylinder and the classification of processing specifications:

According to the working force of the main cylinder and the processing specifications are divided into 100T, 125T, 160T three specifications.

1.     100T is generally used for 140mmX140mmX12mm following cutting angle processing;

2.     The 125T is generally used for 180mmX180mmX16mm following cutting angle processing;

3.     The 160T is generally used for 200mmX200mmX20mm following cutting angle processing.

As the transmission of power transmission tower to improve the level of 160T, angle cutting machine has become a mainstream product in the market, because the nominal force, more reasonable structural design, a large area of cutting angle and highly favored tower processing factory.

Rules and precautions for CNC tube sheet and baffle stack drilling machine

JXZ0818/2 type gantry moving type double spindle set box of high-speed CNC tube sheet and baffle stack drilling machine is mainly used for boiler industry set header pipe drilling and welding processing of basin shaped hole. Can use twist drill can be used in cold hard alloy cutting tools for high speed drilling processing, no need manual scribing and improve the position precision of the holes and drilling efficiency, realizing the automation of drilling.

Use procedures and precautions:

1.        It is strictly prohibited in high speed CNC header drilling and welding operation (if the welding work is needed in the maintenance and need to disconnect the servo line before the operation).

2.        due to equipment for high speed drilling machine, is strictly prohibited in the unattended operation, operation personnel should remain in operation platform, in order to observe the processing condition. If main, auxiliary processing at the same time, each side of the table are should be operating personnel guard (and equipment operation irrelevant personnel prohibited within the range of move devices to stay to watch).

3.        Operator of the numerical control set box drilling machine is strictly prohibited to wear gloves operating equipment.

4.        To promptly clean up the iron inside the machine, especially the V-shaped slide rails on both sides of the part, if too much, will affect the recycling of cutting fluid, and caused a built-up edge leakage.

5.        Check the level of hydraulic pressure station before boot, if the liquid level is too low, it should be timely to add hydraulic oil, and check whether the equipment has hydraulic oil leakage.

6.        Check the oil level automatic lubricating pump, if too low to replenish.

7.        Check the level of the cooling water tank before boot, if the liquid level is too low, add the cooling water and cutting fluid in time.

8.        When the power is switched on, the power supply is in the order: first, open the cabinet main switch, and then open the system key to control the power supply.

9.        No matter what kind of work, be sure to start the hydraulic unit in the header of a drilling machine side (auxiliary side start hydraulic function).

10.    Hydraulic system, cooling system and chip removal system must be started before the automatic operation of CNC high speed drilling machine.

11.    If the move V support, you need to quickly plug the hydraulic connector loose, move to the target position to connect the corresponding fast plug, the plug is absolutely not allowed to dock errors, can refer to the non move stent. After the completion of the move and rotation test for supporting a shaft is in the a axis rotation rise jointly rotating end common fall. If not, the corresponding plug swap.

12.    If the NC high speed set box drilling machine system, the reference point is lost, the system does not allow automatic operation, the missing reference point of the shaft back to the parameter, the return to the parameters are as follows:

13.    X axis: the move chuck to rear limit position, back to the parameters of the model, "X", the X axis will automatically back to the reference process (back to the reference before can be in manual mode will be the X axis moved to close to the reference point, can be saved back to time reference, because back to the reference is slow)

14.    Z axis: in the return mode, the point on the "Z", the Z axis will automatically complete the return process;

15.    A shaft: because a axis configuration for absolute value encoder, in machine tool debugging after need not return to the reference, if there are special circumstances, chuck lock tight side holes are aligned automatically lock the bolt tightening device, open a shaft parameters will P34210 is set to 1, back to the parameters of the model, "a positive turn, back to participate.

Build a working program, must be under the MDA inspection within the range of the rotation angle of the minimum margins hole whether and the chuck claw conflict. Drilling subroutine in borehole completion retracted position must be higher than the minimum margin hole chuck claw height and preventing chuck rotation of the tool spindle damage.
