Q The hydraulic system is responsible for the longitudinal lifting and lateral pushing actions of the clamps. What are the common causes of insufficient clamping force or slow movements?
A Possible reasons include: low hydraulic oil level or high oil temperature, pressure drop caused by worn oil pumps, leakage in the hydraulic valve group or incomplete switching of the electromagnetic valve, and aging of the cylinder sealing ring. It is recommended to first check if the pressure gauge reading is within the set range, then check if there are obvious leaks in the pipeline, and replace the hydraulic oil and filter element if necessary.

Q How many tools can the selected automatic tool changing system (ATC) accommodate? How long does the tool changing process take approximately?
A The specific tool storage capacity can be customized according to customer requirements. It is common to have 8 to 12 tools. The tool changing action is automatically completed by the system. The time from issuing the command to the main shaft restarting usually takes 5 to 10 seconds. It is recommended to clean the tool claws and main shaft taper holes regularly to avoid tool changing failure due to iron filings residue.

Q The maximum rotational speed of the spindle is 3000 rpm. Is it necessary to pre-drill holes or use segmented feed when using carbide drill bits?
A Usually, pre-drilling holes is not necessary, but it is recommended to adjust the feed speed according to the thickness and material of the steel plate. For thick plates (≥20mm) or high-strength steel, a segmented drilling method can be used to facilitate chip removal and reduce cutting temperature. The mist cooling lubrication system needs to ensure sufficient flow to prevent the drill bit from overheating and wearing out.

Q Can this equipment drill holes on all three surfaces of H-shaped steel simultaneously? How can the consistency of hole positions be ensured?
A Yes, it can. The equipment uses 7 CNC axes and can automatically complete precise feeding and positioning. The drilling units on the three surfaces can be processed simultaneously, and with the closed-loop control of the feeding trolley, the hole position accuracy can be ensured to be consistent. It is recommended to regularly calibrate the relative positions of each spindle and check if the workpiece clamping is firm.
