What should be paid attention to during the installation and debugging of the high-speed driller center machine?

The installation and debugging of high-speed driller center machine should focus on basic stability, accuracy calibration, system coordination and safety protection, which directly determine the subsequent processing accuracy and operation safety of equipment.

First, the installation stage: build a stable foundation.

Foundation construction: Before the installation of equipment, special concrete foundation shall be poured to ensure that the flatness error of the foundation is ≤0.1mm/m, and the bearing capacity of the foundation shall be more than 1.5 times the weight of the equipment to prevent resonance during operation.

Equipment in place: when lifting with lifting equipment, it is necessary to strictly follow the lifting points marked in the equipment manual to avoid deformation of the fuselage; After being in place, use a level to calibrate repeatedly in the X, Y and Z axes of the lathe bed, and fix and lock it with anchor bolts.

Environmental control: the installation environment should be kept clean and dry, with the temperature controlled at 15-25℃ (temperature difference ≤5℃/ day) and humidity ≤60%, and at the same time, it should be far away from seismic sources (such as punching machines and air compressors) to avoid dust and oil pollution.

Second, the debugging core: focusing accuracy and coordination

Electrical system debugging

Line inspection: Check whether the main power supply, servo motor and control system (such as FANUC and SIEMENS) are connected correctly, and the grounding resistance should be ≤4Ω to prevent leakage or signal interference.

Function test: after power-on, test the safety functions such as emergency stop button, travel limit and alarm device one by one to ensure sensitive response; At the same time, check whether the servo driver parameters match the motor to avoid overload.

Mechanical precision calibration

Geometric accuracy: use laser interferometer to detect the positioning accuracy of X, Y and Z axes (required to be ≤0.005mm/100mm), repeated positioning accuracy (required to be ≤0.003mm) and the verticality between the spindle and the workbench (error ≤0.002mm/m).

Spindle debugging: start the spindle, test the running stability at different speeds (from low speed to rated high speed), and use a dial indicator to detect the radial runout of the spindle (it needs to be ≤0.003mm) to ensure that there is no abnormal vibration or noise.

System collaborative debugging

Tool system: after installing the tool magazine, debug the accuracy of the tool changing mechanism to ensure the smooth tool changing action and the tool clamping accuracy (tool handle jumping ≤ 0.002 mm); Simulate the automatic tool changing cycle during the trial run, and check whether there is any tool sticking or wrong tool.

Coordinate setting: Set the coordinate system of the machine tool through the edge finder and dial indicator, and repeatedly verify the consistency of the coordinate origin to ensure that the coordinate deviation is ≤0.002mm during machining.

Third, safety and trial operation: avoiding risks

Safety protection inspection: confirm that the interlock device of machine tool protective cover and safety door is effective, and the high-pressure cooling system and chip removal system are well sealed to avoid coolant leakage or chip splashing; At the same time, safety warning signs are posted to clarify the operation specifications.

No-load test run: Under no-load condition, let the equipment make full-stroke reciprocating motion along X, Y and Z axes (at least 3 cycles), and observe whether the running speed and acceleration of each axis are stable, and whether the servo system has abnormal sound or overload alarm.

Load test: select standard specimens (such as 45# steel) for trial cutting, test basic functions such as drilling and tapping, check the dimensional accuracy and surface roughness of the machined parts (which must meet the requirements of the equipment manual), and fine-tune parameters (such as feed speed and spindle speed) according to the results.
