D type is a general-purpose probe with a broad applicability range. | |
|
DC Type is a shortened version of D type，good for testing in a limited space. | |
|
D+15 type is another modified version of D type with an extended probe in length of 15mm； suitable for testing slots and gear surfaces. | |
|
C type with low impacting energy for testing small,light,and thin specimens as well as the shallow surface of a hardened layer. | |
|
G type with high impacting energy for testing large，thick，or heavy specimens and some rough surfaces of cast or forged specimens. | |
|
D type device is the typically provided as a standard accessory；other types are optional and can be supplied at additional cost. | |
 |
系列化冲击装置 | |
|
|
D型为基本型，适用范围很宽。 | |
|
|
DC型为D型的超短改造型，适合空间高度受限的场合（长度86mm）。 | |
|
|
D+15型为D型的加长改造型，它有一个15mm的细长端部，适合于沟槽、齿面的测试 | |
|
|
C型的冲击能量很小，于测试小、轻、薄部件及深度较浅的表面硬化层。 | |
|
|
G型冲击能量很大，于大、厚、重及表面较粗糙的铸锻件。 | |
|
|
本机标准配置为D型冲击装置，其它冲击装置可根据需要选用。 | |

 |
The special supporting rings can be selected while the radius is less than 30mm. 当被测工件的曲率半径小于30mm时，可选配异形支撑以保证测试精度。 |
