High-speed precision punching precision detectable amount of maintenance cylinder return

Steel cylinder for use on high-speed precision punch detection rules with a small base area, measured in any direction Jieke, cheap, can bring advantages to the customer site, and the other can be re-polished surface coating abrasion and precision error when it, detection accuracy standard can reuse, avoid adding new costs for items purchased.
Precision cylindrical gauge, according to CNS 8093-B6059 specifications, the vertical axis direction of the diameter difference must meet 2 + (L / 200) um standards, and L refers to the length of the cylinder gauge. So punching cylinder common rules, which permit the difference calculation accuracy up as follows:

Because measuring cylinder classified as testing standards in the use and maintenance needs special care, otherwise the cylindrical gauge damage, caused by the error of the measurement. Since it is a cylinder measuring gauge, regularly check for the important projects necessary, can be taken when inspectors use more direction than the right, to ensure measurement accuracy.
SAMHOOR mechanical explain in detail here, focusing on the use and maintenance of cylindrical gauge should be noted:
1, the measurement precision punching process should be handled with care
Cylindrical gauge due to the small base area, it is easy to lapse or when dumped by collisions. Although most of the cylindrical gauge is hollow, but still has a considerable weight, tipping cylinder will regulate itself in addition to damage outside or bottom of the workpiece under test platform shall likewise hit, so be sure to be careful.
2 wipe clean to the bottom of the first weight,
Cylindrical gauge bottom area is small, but if the bottom does not clean as well as placement of the cylindrical gauge platform surface is not wiped clean, it will cause an error verticality. The longer the length of the cylindrical gauge, vertical error arising due to the bottom of the dirty will be greater.
3, after punching accuracy test is completed to fully rustproof
After using steel cylindrical gauge to have to do rust treatment, to prevent rust. Human hands will inevitably have hands sweat, perspiration in with the salt, it is easy for metal rust. Even after the cylindrical gauge chrome plated, strong antirust ability, antirust effect work still can not be ignored.
4, long-term collection to erect upside down
When the cylindrical gauge collections, preferably upside down, placed at the bottom of the upright cylindrical gauge is very important, in order to avoid abrasion or bruise dirt, so simply placed upside down, it is safer. The case of recumbent collections, in addition to the more space, the cylindrical gauge is also easier to roll, collision, scratches and other accidents.
5, stored in the warehouse to use padded protection
To avoid cylindrical gauge scroll down or damaged, the best way is to do storage protection with upholstered or wood. As far as possible with the characteristics of the special wooden box, but if the absence of a wooden box, it is recommended to place lined with padded or wooden floor area, and then coated with a bubble bag or cushion, it would be more secure.
Note: (1) refers to an air consumption per minute of air to be consumed when the clutch intermittent operation.
(2) In order to ensure stable performance punch and punch safety, punch with a pressure switch, when the air pressure is lower than 0.4MPa, the punch will not boot
