A. The machining accuracy of the usual horizontal lathe is as follows:
Roundness: 0.015mm, cylindricality: 0.02/150mm, flatness 0.02/¢150mm, surface roughness: 1.6Ra/um.
B. The machining accuracy of vertical lathes is as follows:
Roundness: 0.02mm, cylindricality: 0.01mm, flatness 0.03mm.
The above processing accuracy is only a relative reference value, does not mean that all lathes are compliant, many lathe equipment according to the specific requirements of the manufacturer and the specific conditions of the assembly have a certain amount of up and down floating, but no matter how large the floating amount is, its processing accuracy value must meet the requirements of the national standard for this type of equipment, if the purchase of the equipment, its processing accuracy requirements do not meet the requirements of the national standard, the purchaser has the right to refuse acceptance and payment.
