By using above-mentioned technical proposal, because the deadweight of wheel body is larger, therefore the inertia produced during wheel body motion is larger,
Wheel body is contacted with other objects in transportation can cause wheel body easily by gouge, and the anti-work that wheel body is subject to is buffered by chamfering
Firmly, the beneficial effect of protection wheel body is achieved.
Preferably, the work department is detachably connected with wheel body, the wheel body lateral wall is set to inclined to side
Domatic, the work department madial wall is set to coordinate the domatic of wheel body.
By using above-mentioned technical proposal, after the frosted layer serious wear on work department surface, diamond roller will be influenceed
It is normal use, the work department that now only need to more renew just can continue to ensure machining accuracy, and achieving reduces the beneficial of cost
Effect.
Preferably, being arranged with the spacing ring for fastening work department in the fixing groove.
By using above-mentioned technical proposal, work department is set on wheel body, spacing ring is set in fixing groove, just may be used
To play position-limiting action to work department, it is to avoid wheel body vibration can cause the problem of work department slides during processing, achieve enhancing
The beneficial effect of structural soundness.
In summary, stability when the utility model can effectively strengthen processing, just can now improve diamond
The velocity of rotation of roller, so as to reach the beneficial effect for improving operating efficiency.
