Furthermore, four chip grooves are formed in the side face of the cutter handle.

Further, the cutting angle of a cutter of the blade is 15-25 degrees, the thickness of the blade is 4mm, and the blade is made of hard alloy materials.

Further, the distance between the tips of the two blades was 105.3 mm.

To sum up, the utility model discloses following beneficial effect has:

1. the cutter adopts the design of integrally forming the blade, the cutter handle and the cutter mounting shaft, and the cutter mounting shaft is directly connected with the motor, so that the falling-off condition is less, the cutter integrally avoids the situation that the cutter head is thrown away, and the cutter is more stable and safer;

2. the chip removal groove is formed in the cutter handle, so that sawdust can be removed in time, the influence on the normal use of the cutter is avoided, unnecessary secondary cutting of the cutter caused by the sawdust is avoided, the passive abrasion of the cutting edge of the cutter is reduced, the service life of the cutter is effectively prolonged, operators in a wood factory need to grind the cutter at least four times every day before, the condition that the cutter is ground twice every day is improved, partial productivity is liberated, the time of work stagnation caused by cutter grinding is saved, and the production efficiency is improved by more than 15%;

3. cutter installation axle and handle of a knife are the arc structure, compare in general square structure cutter, can bear higher rotational speed, by every minute 8000 changes about improve to every minute 12000 and change, it is higher even, thereby the processingquality on wooden surface has been improved, the finish that timber was processed the surface has been improved, and all be superior to common square welding integrative sword such as stability, low noise, aspects such as whole equilibrium, the main shaft rotational speed of this kind of cutter at present is all at every minute 10000 changes, the utility model provides a cutter is through experimental back, and maximum rotational speed can reach every minute 12600 and change, leads current industry standard.

Detailed Description

Example (b):

the present invention will be described in further detail with reference to the accompanying fig. 1-2.

The utility model provides an integrative sword of carbide welding formula, as shown in fig. 1-2, includes cutter installation axle 1, and cutter installation axle 1 is arc foraminiferous axle, and cutter installation axle 1's both ends respectively have a handle 11, and handle 11 is the arc structure, and two handles 11 are set up about cutter installation axle 1's centrosymmetry, are equipped with a blade 2 on two handles 11 respectively, and the knife face 13 of blade 2 is the saw form, cutter installation axle 1, handle 11 and blade 2 integrated into one piece.

The outer diameter of the cutter mounting shaft 1 is 50mm, the main diameter of the cutter mounting shaft 1 is 30mm, and the length of the cutter mounting shaft 1 is 75 mm.
