Commissioning of machining centers

The purpose of machine tool debugging is to check whether the machine tool installation is stable, and whether the transmission, manipulation, control and other systems are normal, sensitive and reliable.

The commissioning and trial operation is carried out according to the following steps:

Add oil to a lubricating point according to the requirements of the manual, fill the hydraulic oil tank with hydraulic oil that meets the requirements, and connect the air source.

Power on, each component is powered separately or each component is powered on and tested once, and then fully powered. Observe whether each component has an alarm, manually observe whether each component is normal, and whether each safety device works. Even all aspects of the machine tool can be operated and moved.

After grouting, after the initial operation of the machine tool, the geometric accuracy of the machine tool is roughly adjusted, and the relative position of the disassembled main moving parts and the host is adjusted. Align the manipulator, tool magazine, exchange table, position alignment, etc. After these tasks are done, the anchor bolts of the main engine and each accessory can be filled with quick-drying cement, and the reserved holes for the anchor bolts can be leveled.

For debugging, prepare various testing tools, such as precision level, standard square feet, parallel square tubes, etc.

The level of the machine tool is finely adjusted so that the geometric accuracy of the machine tool can reach the allowable error range, and multi-point pad support is used to adjust the bed to the level in a free state to ensure the stability of the bed after adjustment.

Adjust the position of the manipulator relative to the main shaft by manual operation, and use the adjustment mandrel. When installing the maximum weight tool holder, it is necessary to perform automatic exchange of the tool magazine to the spindle position for many times, so as to be accurate and not collide.

Move the worktable to the exchange position, adjust the relative position of the pallet station and the exchange worktable to achieve a smooth automatic exchange of the worktable, and install the maximum load of the worktable for multiple exchanges.

Check whether the setting parameters of the numerical control system and the programmable controller plc device conform to the specified data in the random data, and then test the main operation functions, safety measures, and the implementation of common instructions.

Check the working conditions of accessories, such as machine tool lighting, cooling shields, various guards, etc.

After a machining center is installed and debugged, due to its many functions, after installation, it can run automatically for a long time under a certain load to check whether the functions of the machine tool are complete and stable. The running time can be 8 hours a day for 2 to 3 days or every 24 hours for 1 to 2 days. Continuous operation can use the test program.

Acceptance of machining center

The acceptance of machining center is a complex inspection technology work. It includes the comprehensive performance detection of the machine, electricity, hydraulic and gas parts of the machine tool and the detection of the static and dynamic accuracy of the machine tool. There is a special organization in my country, namely the National Machine Tool Product Quality Inspection Center. The user's acceptance work can be carried out in accordance with the acceptance method of the institution, or the above-mentioned institutions can be invited for acceptance. Mainly focus on two aspects:

Machining Center Geometric Accuracy Check

The geometric accuracy of the machining center is the geometric error after assembly, and the inspection contents are as follows:

• Flatness of the table

• Mutual perpendicularity of movement in each coordinate direction

• The parallelism of the movement in the x-axis direction to the table surface

• The parallelism of the movement in the y-axis direction to the table surface

• The parallelism of the movement in the x-axis direction to the sides of the upper and lower grooves of the table

• Axial play of the main shaft

• Radial runout of spindle bore

• The parallelism of the spindle box moving along the z-coordinate direction to the spindle axis

• The perpendicularity of the axis of rotation of the main shaft to the working table

• The straightness of the headstock movement in the z-coordinate direction
