UV235 Impact Sample Notch Broacher
Impact test is the important experimental method of mechanical
properties of materials. Processing of the impact specimen notch
generally adopts the special broaching machine and special broach.
This machine is referred to the latest foreign impact specimen
notch broaching machine design and has the following
1. Design of structure is compact and component processing is
precise; the machine adopts the linear guide and precision ball
screw transmission structure, ensure the motion parts running
precise and reliable and the broach operation state stable and
accurate. Mechanical movement is exempt from the hydraulic
transmission maintenance inconvenience and the risk of oil spills.
2. It adopts the broach precision positioning structure and ensures
the geometric accuracy of incision; and the trimming specimen
positioning device can realize the fine turning of depth of notch
processing and ensure the gap size precision.
3. It has the advantages of rapid tool change and free adjustment.
This machine adopts unique broach installation and fixed mode, not
only with convenient replacement of broach (each tool change only
need 1 minute), but also without any adjustment after change. The
advantage of rapid free adjustment tool change make need not use
double knife structure.
4. The broach has the advantages of simple structure and small
size; reduce the cost of cutting tool.
5. It has multiple-safety protection device. In addition to the up
and down stroke limit protection of broach, the broach can action
after open table cover and it avoids misoperation. After open the
table cover, it can be as an extension of working table
(additional), to place the tool and specimen, rated load 5Kg.
6. The working noise is extremely low, quiet environment for
