Product Description

1. JG

JG type manual adjustment scraping and rolling combination cutting tool


The skiving and rolling is equipped with a new manual expanding and shrinking cutter mechanism. The matching gap between the cutter and the guide sleeve can be effectively controlled by adjusting the size of the ball. It does not need to be equipped with pneumatic or hydraulic device. And it has wide applicability, which can be used on all common deep hole machine, and it is easy to operate.  The floating boring block adopts the special coating fine boring blade, which has the advantages of light and rapid cutting, large single rotary feed, smooth chip removal, good abrasion resistance, convenient and reliable replacement and so on.


The scraping tool is a newly developed tool by our company's technical staff. It adopts a brand-new expansion and contraction tool mechanism. The floating boring block adopts a special coated fine boring blade, which has the advantages of light cutting, large feed rate per revolution, smooth chip removal and wear resistance. Good performance, convenient and reliable replacement, etc.

Features of JG type scraping tool:

1. Reduce the precision requirements for the machine tool guide sleeve. The adjustable ball size can effectively control the fit gap between the tool and the guide sleeve, reduce the requirement for the dimensional accuracy of the inner hole of the guide sleeve, and avoid the thread appearing in the processed inner hole when the conventional TGG boring roller head and the guide sleeve are too large. The situation. Can effectively improve the quality of inner hole processing.

2. The operator's technical requirements are reduced. For workpieces with unsatisfactory dimensions, the secondary processing can be carried out by adjusting the rolling amount, which can effectively control the rejection rate.

3. Fine boring adopts machine-clamped coated blade, which is stable and reliable in size. It is convenient and quick to replace the blade.

4. Low requirements for machine tools, no pneumatic or hydraulic device is needed compared with similar foreign products. All ordinary deep hole machine tools can be used. Easy to operate.

5. The floating precision knife and the ball part can be adjusted arbitrarily within the range of 1mm without changing any accessories, which can realize the renovation and repair of the old cylinder. Adapt to the aperture of different tolerance levels.

6. Due to the structure of the floating precision tool, the force of the tool is more even, which can achieve large feed, and the processing efficiency is increased by 2-3 times compared with the ordinary TGG combined boring and rolling head.
