Product Description
JD10A Projection Length Measuring Machine

The Projection length measuring machine is a high precision optical instrument for measuring length. It can be used to determine the size of workpiece by means of direct and differential measurements. The chief uses of the machine are as follows:
. Differential measurements of the gauge block of 4th and 5th grade over 100 mm;
. Direct measurements of the calibration rods of the micrometer calipers, inside calipers micrometer and self-made measuring rods; Internal measurements of calipers gauge and bore diameter; Measurement of external thread pitch diameter. It can be used in inspection department of various factories and mines, scientific research institutes and the state metrological organizations.

CX11A The Cutter detecting instrument

It adopts rotatble worktable to inspect workpiece by pressing. The rotatable worktable with accurate reticule marking value can measure the parameters of cutter rapidly and is suitable for inspection of small cutters.
It adopts ergonomics 45° Image inspection method.
The light source is LED cool light source illumination.
The X direction is V shape precision line guideway and adopts optical lever transmission. And the Z direction uses precision line slide guideway and adopts precision lead screw driving and gear transmission.
The side handwheel saves labour for the up and down.

The instrument is a new product developed accoring to the urgent need of the tool factory. It's main application range is
The precision workpiece that is not inspected with common gauge (such as the vernier caliper and micrometer).
Workpiece by large batch production, especially suitable for measuring all kinds of parameters of cylinder cutters (milling, cutters, wring cutters and aiguiles) produced by tool factory.
The instrument has the advantage of compact structure, convenient operation, rapid inspection, digital display and convenience. Therefore, it is an applied inspecting instrument with high efficiency.
