Review VT840 for your part

For parts with drilled holes or tapped features, compare this model’s table, travels, spindle and tool interface with the fixture and hole pattern. Confirm the hole or thread size, depth, material and required cycle. A machine-family name or spindle speed alone does not establish a particular tapping capacity, cycle time or loading arrangement.

What is the Tiezheng VT840?

The VT840 is a vertical drilling and tapping center with a source-listed A/B configuration structure. The A configuration uses a BT30 drilling and tapping spindle. Both configurations use direct-drive spindles, with speed and power specifications shown below. The final machine configuration remains controlled by the signed quotation and technical agreement.

Which VT840 work envelope is documented?

The reviewed source records a 1000 x 400 mm table, 800 x 400 x 350 mm X/Y/Z travel, a 100-500 mm spindle-nose-to-table range and 350 kg maximum table load.

How do the VT840 A and B spindle configurations differ?

The A configuration is listed with a BT30 direct-drive spindle, 20000 rpm speed and 3.7/5.5 kW power. The B configuration is listed with a direct-drive spindle, 12000 rpm speed and 7.5/11 kW power. Confirm process suitability against the part drawing.

How should buyers compare the VT840?

Use the published values for model screening and RFQ preparation. Compare table size, travel, spindle variant, tool capacity, utilities and machine dimensions, then confirm control, electrical standard, workholding, tool package, chip handling, automation interfaces and acceptance criteria.

What should be sent for a VT840 RFQ?

Send the part drawing, material, critical tolerances, annual volume, target cycle time, required spindle variant, preferred control, workholding or automation requirement and destination country.

Does this specification table define the final supplied configuration?

No. Source-verified rows support comparison. The signed quotation, technical agreement and acceptance record control the final supplied configuration.
