Definitions

• Carrier tool for inserts with fine adjustment elements
• the invention relates to a carrier tool for cutting plates in a cutting tool according to the preamble of claim 1.
• the invention is based on the object of significantly improving a carrier tool for cutting inserts with fine adjustment elements according to the preamble of claim 1 with regard to the setting accuracy and the handling.
• the fine adjustment element consists of a rotatable adjusting bolt with a lateral surface designed as a conical surface, that the conical surface forms a plate seat wall, and that the adjusting bolt is arranged in a guide bore and this guide bore extends at an angle b to the plate seat wall.
• the outer surface at the largest radial extent of the conical surface merges into a cylindrical surface with the same radial extent and the diameter of the cylindrical surface on the adjusting bolt is equal to the diameter of the guide bore.
• This cylinder surface absorbs the cutting forces during machining.
• the adjusting bolt has an external thread or a threaded bore for precise adjustment at one end.
• the conical surface expediently has a cone angle a of 1 ° to 30 ° and the angle b is approximately half as large as the angle a.
• the adjustment bolt has a slot, hexagon socket, Torx or screw drive on one end.
• the adjusting bolt preferably consists of hardened steel, hard metal or industrial ceramics.
• FIG. 1 shows an adjustment bolt 30 according to the invention for fine adjustment.
• the adjusting bolt 30 has an external thread 31 for fastening in the carrier tool 29.
• This adjusting bolt 30 is the conical surface 32 with a conical angle a of approximately 1 ° to 30 ° and the subsequent cylindrical portion or the cylindrical surface 33.
• FIG. 2 shows a simplified top view of a cutting plate 28 in a carrier tool 29.
• the position of the adjusting bolt 30 can clearly be seen, which is installed as a special feature at an angle b behind the cutting plate 28.
• This angle b is adapted to the angle a of the conical surface 32 and usually has half the value of the cone angle a.
• the taper surface 32 is in contact with the insert side surface 34.
• a rotation of the adjusting bolt 30 clockwise about its axis would move the cutting plate 28 to the left due to the guide bore 35 arranged at an angle ⁇ and the conical surface 32 parallel to the cutting plate 28.
• the cylindrical portion or the cylindrical surface 33 is pressed against the wall of the guide bore 35 and also later absorbs the cutting forces in the cutting operation.
• the cutting plate 28 is of course fastened in the carrier tool 29 by suitable means, such as clamping wedges.
• a hexagon socket 36 is arranged on its end face.
