1. Which machine parts need replacement?

① Cutting tools (milling cutters/drill bits): Most prone to wear; replace periodically based on the material being processed, the intensity of the work, and the operating time.

② Guide rail slider seals: Prevent dust and debris from entering; replace after wear.

③ Transmission components:

1) Synchronous belt: May develop tension or cracks after prolonged use; replace.

2) Lead screw nut: Wear will affect accuracy; replace.

④ Cooling system components:

1) Spindle water cooler coolant needs periodic replacement.

2) Water pipes and pumps may age and become clogged.

⑤ Electrical wear parts:

1) Limit switches and proximity switches may fail due to impact or dust.

2) Relay and contactor contacts may burn out.

2. What materials can it process? What are the minimum and maximum thicknesses?

① Processable Materials:

Non-metallic materials: Acrylic, PVC, ABS, wood, medium-density fiberboard (MDF), two-color board, rubber, plastic, epoxy resin board, etc.

Soft metals: Aluminum, copper, brass, etc. (requires low depth of cut, high speed, and proper cooling).

Others: Composite materials, artificial stone, wax molds, etc.

② Thickness Range:

Minimum thickness: Theoretically, it can process foil-level materials (e.g., 0.1mm), but in practice, it is affected by the flatness of the fixture and the rigidity of the material. It is generally recommended to be ≥1mm.

Maximum thickness: Limited by the Z-axis travel. The Z-axis travel of the 6090 model is usually 100-200mm. Actual processable thickness = Z-axis travel - clamping height - tool length.

For example, if the Z-axis travel is 150mm, and the fixture and tool occupy 50mm, then the maximum processable thickness is approximately 100mm. When machining excessively thick materials, spindle power and tool rigidity must also be considered.

3. What are the dimensions and diameters of the end mills used?

End mill diameters: 3.175 mm, 4 mm, 6 mm, 12.5 mm.

Tool length generally does not exceed 100 mm.

4. What are the installation requirements for the electrical panel?

Environment: Install in a dry, well-ventilated area with low dust, no oil mist, and no vibration. Keep away from coolant and splashing chips.

Heat Dissipation: Ensure sufficient space around the panel for heat dissipation (usually ≥10cm). Avoid direct sunlight.

Power Supply: Independent power supply, stable voltage (220V±10%), reliable grounding (grounding resistance ≤4Ω). A voltage regulator or isolation transformer is recommended.

Wiring: Separate power cables (spindle, stepper/servo motors) from control signal lines to avoid interference. Cables must be run in conduits or protected by cable chains.

Safety: The panel housing must be reliably grounded, equipped with an emergency stop button, and clearly marked with operating instructions.

What types of maintenance are required? How frequently?

A. Routine Maintenance (before and after each shift):

Clean the table, guide rails, and lead screw of chips and dust.

Check the spindle cooling system (air-cooled/water-cooled) for proper functioning.

A. Weekly/Monthly Maintenance:

Lubrication System: Add the specified grease or oil to the guide rails and lead screws (weekly to monthly, depending on usage frequency).

Check drive belt tension: Prevent excessive looseness or tightness.

Clean electrical cabinet filter: Prevent dust accumulation that affects heat dissipation.

Check all connecting screws and nuts for looseness.

C. Quarterly/Semi-annual Maintenance:

Comprehensive Inspection of Electrical Connections: Tighten terminal blocks, relays, and contactor contacts.

Calibrate Machine Tool Accuracy: Check and calibrate the perpendicularity, parallelism, and repeatability of each axis.

Replace Coolant (for water-cooled spindles): Clean the water tank and water circuits to prevent microbial growth and blockage.

Inspect and replace worn limit switches, seals, and other vulnerable parts.

D. Annual Maintenance:

Professional Comprehensive Inspection: Recommended to be performed by a professional technician.

Check spindle radial runout and axial movement: Adjust or repair by a professional if necessary.

Control system backup and update: Back up parameters and check the status of the control system software and hardware
