1Scope
This Japanese Industrial Standard specifies the methods of running testand accuracy inspection of machining centres (vertical type) of the verticalmonoaxial type having automatic tool replacing devices (including the turrettype) and whose maximum travelling distance in the control axis direction iswithin 2000 mm.
The units and numerical values given in { ]in this standardRemark:are in accordance with the gravitational system of units andare appended for reference.
2，Method of Running Test
2.1 Function Test
2.1.1 Function Test without Use of Numerical Control The function testof machining centres (vertical type) without use of numerical control shall beperformed by operating the respective parts manually and according to theconditions specified in Table 1.
2.1.2Function Test by Use of Numerical ControlThe function test by useof numerical control of machining centres (vertical type) shall be performedby operating the respective parts by using test numerical control tapes () orother numerical control commands (3) according to Table 2.
2.2 No-Load Running Test In the no-load running test of machining centres(vertical type), the main spindle shall be operated by starting with the lowestspeed,then.at the speeds of respective stages ,and at the highest speed continuously for 30 to 60 min as a rule.During this operation, the respectiveitems specified in Recording Form 1 of Table 3 shall be measured [refer to 3.3of JIS B 6330].
The feed speed used shall be the lowest，intermediate,highest，andrapid traverse,and the respective items specified in Recording Form 2 ofTable 4 shall be measured for each speed.
In addition，vibration and noise shall be observed. Where vibrationand noise are particularly made the problem， inspection shall be made inaccordance with JIS B 6003 and JIS B 6004.
2.3 Continuous No-Load Running TestThe continuous no-load runningtest of machining centers (vertical type)shall be performed by running themachine continuously for about 2 h ($) by a test tape or other numericalcontrol command (3) covering various functions and examining for theoceurrence of abnormalities.
