CNC Drilling Machine
January 31, 2017 CNC Machine
CNC drilling machine is mainly used for drilling, reaming, reaming, tapping and other processing. It is the first choice for the drilling of large-sized parts, such as super-long stacking plate, stringer, structural steel, pipe-shaped parts and other porous systems, such as Fuyuan Chenghai, in the automobile, locomotive, shipbuilding, aerospace and engineering machinery industries.
Table of content
1, the coordinates of mobile use servo motor drive, easy to operate, flexible, precision and stability.
2, the basic layout: the slide in the bed length of the whole through the movement, unilateral open, simple structure, easy to install the workpiece up and down and clean after get off work hygiene, easy maintenance, small footprint, suitable for long parts Processing and production.
3, the slide on the column and the same general radial drilling column cylindrical column, the rocker arm can be up and down movements, easy to work with different height of the workpiece.
4, spindle 16 speed, cutting torque to expand a few times, for the Mohs taper hole, you can directly install the drill.
5, the bed for the casting structure, can be extended section, the user can choose or customized.
6, X-axis movement of the slide using the German imports reducer, gears, racks, to ensure that the movement of the stiffness and movement accuracy.
7, bed rails do not pull the board to ensure that the rack, grating and electrical and mechanical switches from the outside world pollution.
8, X-axis using imported original grating to ensure that the X-axis positioning accuracy.
9, the use of Siemens 802D CNC system, AC servo and rare earth permanent magnet motor, high performance, high reliability, safety and durability.
10, ultra-thin LCD display, anti-oil keyboard, the appearance of fine and generous.
1, low-frequency torque, the output is stable
2, high-performance vector control
3, the torque dynamic response fast, stable high precision
4, deceleration stop fast
5, anti-interference ability
1, work carefully check the grid voltage, oil pump, lubrication, oil is normal, check the pressure, cooling, tubing, tools, tooling fixture is intact, and make regular maintenance of the machine work.
2, the machine power to start, the first mechanical zero return operation, and then test run 5 minutes to confirm the machinery, tools, fixtures, workpieces, numerical control parameters such as correct before they can begin normal work.
3, carefully check the program preparation, parameter setting, action sequencing, tool interference, workpiece clamping, switch protection and other links are completely correct, so as to avoid accidental processing cycle, damage to tools and related components. In strict accordance with the operating procedures for the trial cut knife, after the completion of debugging to do a good job of program protection.
4, automatic cycle processing, should be closed to protect the sliding door, the spindle rotation while the need for manual operation, be sure to make their bodies and clothing away from the rotating and moving parts, so as not to cause the accident involved in clothing.
5, the spindle or turret knife loading knife operation must be in the state of mechanical movement to stop, and pay attention to coordination and cooperation between the staff, so as to avoid accidents. In the manual tool change or automatic tool change, pay attention to the turret, knife library, mechanical arm rotation and the installation of tools such as the location of the body and the head away from the tool swivel, so as not to bumps. On the machining center machine tools, but also should pay attention to check the tool magazine tool number and the corresponding relationship between the tool number to prevent confusion caused by tool change knife knife knife interference or processing accident knife collision.
6, the workpiece clamping to clamp, so as not to fly out of the workpiece caused by the accident, the completion of clamping, the attention should be taken out of the chuck wrench and other adjustment tools removed, so as not to spin the spindle after the accident caused by thrown.
7, the machine operator should be able to handle the general alarm failure, if a serious failure, power should be quickly and protect the scene, timely reporting and make records.
8, the work is completed, the machine guide rails, table clean, and carefully fill out the work log.
Extend the life of components and components of the wear cycle to prevent a variety of failures and improve the average CNC drilling machine working hours and service life.
4.2 CNC drilling machine should pay attention to the use of the problem
(1) the use of CNC drilling machine environment: the best for CNC drilling machine placed in a constant temperature environment and away from the vibration of the larger equipment (such as presses) and electromagnetic interference devices.
(2) power requirements
(3) CNC drilling machine should be operating procedures: the regular maintenance, maintenance, failure to pay attention to record the scene of protection.
(4) NC drilling machine should not be long-term storage
(5) pay attention to training and equipment operators, maintenance personnel and programmers
4.3 CNC system maintenance
1, strictly abide by the operating rules and routine maintenance system
2, to prevent dust from entering the numerical control device: floating dust and metal powder easily lead to insulation resistance between components decreased, resulting in failure or damage to components.
3, regular cleaning CNC cabinet cooling ventilation system
4, often monitoring the grid voltage of the numerical control system: grid voltage range of 85% to 110% of the rated value.
5, regularly replace the memory battery
6, the NC system when not in use for a long time to maintain: often to the NC power system or CNC drilling machine run temperature program.
7, the backup circuit board maintenance.
4.4 Maintenance of mechanical parts
1, Screw and guide rail maintenance
① regular inspection, adjust the axial gap screw nut to ensure the accuracy of reverse transmission and axial stiffness;
② regularly check the screw support and bed connection is loose and whether the support bearing damage. If the above problems to tighten the loose parts in time to replace the support bearings;
③ The use of grease ball screw, once every six months on the screw cleaning the old oil, replace the new oil. Lubricated with the ball screw, the machine work every day before refueling;
④ Note to avoid hard dust or chips into the screw shield and work during the impact on the protective cover, protective equipment to be replaced in a timely manner.
2, The maintenance of the main shaft
① regularly adjust the spindle drive belt tightness;
② to prevent all kinds of impurities into the tank. Replace the oil once a year;
(3) Keep the connection between spindle and tool holder clean. Need to timely adjust the displacement of the hydraulic cylinder and piston;
④ to timely adjust the weight.
4.5 Maintenance of pneumatic systems
1, the removal of compressed air impurities and moisture;
2, check the oil mist system in the oil supply;
3, to maintain the system sealing;
4, pay attention to adjusting the work pressure;
5, cleaning or replacement of pneumatic components, filter.
