What is the Tiezheng VT840?
The VT840 is a vertical drilling and tapping center with a source-listed A/B configuration structure. The A column identifies a BT30 drilling and tapping spindle, while the B column identifies a BT40 spindle configuration. 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 BT40 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 the source matrix define the final supplied configuration?
No. Source-verified rows support comparison. The signed quotation, technical agreement and acceptance record control the final supplied configuration.
