standard lathe

Better standard lathe. There are national standards, industry standards, such as factories, as well as internal control standards for the use of corporate standards, the two sides of supply and demand in the contract provided for in terms of technology and special requirements are also based on the test.

Turning to the corresponding standards, professional standards and complete product classification standard. The main criteria: GB6477.3-86 "metal cutting machine tools terms", GB5268-85 "turret lathe knife mounted high slot", ZBJ53019-90, JB/T5598-91 "instrument parameters lathe and family-spectrum", JB4135 -85 "Instrument precision lathe", JB/T4136-96 "instrument lathe technology", JB4138-85 "precision fine-bed vehicle", JB3754-84 "single-axis longitudinal automatic lathe parameters", JB1464-94 "single-axis vertical Automatic precision lathe cut ", JB/T54012-93" single-axis longitudinal automatic lathe technology ", ZBJ53010-89" single-axis automatic lathe technology ", JB3644-84 ,4321-84" horizontal multi-axis precision automatic lathe, Technical conditions ", JB/T5762-91, JB/T5597-91" turret lathe with the parameters of family-spectrum ", GB4683-93, ZBJ53011-89" turret lathe accuracy, technical conditions ", ZBJ53009-89, ZB/Z123 -76 "Vertical lathe with the parameters of family-spectrum", JB4116-96 "single-column double-column vertical lathe accuracy", JB/T3317-93, JB/T6590-93 "multi-tool lathe chuck and the parameters of family-spectrum" , ZBJ5307-90, ZBJ53018-90 "chuck more precision lathe knife, technical conditions", GB1582-93, JB/T6085-92 "horizontal lathe with the parameters of family-spectrum", GB/T4020-97 equivalent ISO1708: 1989 , JB/T2322-93 "horizontal precision lathe, technical conditions", JB/GQ1125-88, JB/GQ1126-88 "Jane CNC lathe horizontal accuracy, technical conditions", JB4369-86, JBn4368-86 "number Horizontal control precision lathe, technical conditions ", JB4117-85" heavy-duty horizontal lathe accuracy ", JB/T3849.1 ~ 3849.2-94" profiling precision lathe, technical conditions. " When tested, but also in the light of JB2670-82 "metal cutting machine tools General test."
Exports may not be lower than first-class goods.

3. Test project
Test, except in accordance with the relevant standards and technical requirements for acceptance to create the appearance of inspection, should be the main accuracy and performance testing. The design of precision machine tools is reflected in the quality of the assembly is to ensure that the performance of equipment, various types of precision lathe test project has about 20, can be summarized as follows:
(1) the geometric precision, that is the basis of pieces of precision machine tools, it is the decision of the basic conditions for processing performance. Include: the rail bed in a straight line, the axis of rotation accuracy, slipped boards, Tailstock, and other moving parts and guide the direction of the movement, the main axis of rotation parallel or perpendicular and so on.

(2) transmission accuracy, refers to the transmission system in conjunction with both ends of the chain pieces of the relationship between movement of the accuracy of the main lathe is the main transmission chain between the screw and accuracy.
(3) positioning accuracy, is the moving parts of a machine from one location to another theory is scheduled to arrive at the location and movement up to the actual location of the margin. CNC machine tools for high positioning accuracy.
