Description
Technical Field
The utility model relates to a grooving cutter field especially relates to an inner hole groove machining cutter with adjustable.
Background
The length of the blade exposed out of the cutter of the existing inner hole groove processing cutter determines the maximum processing depth of the cutter. The longer the cutting edge is exposed out of the cutter bar, the greater the maximum processing depth is, but the torque borne by the cutter bar is increased during processing; conversely, the shorter the cutting edge is exposed out of the cutter rod, the smaller the maximum processing depth is, but the torque borne by the cutter rod during processing is reduced.
The length of the cutter blade exposed out of the existing inner hole groove machining cutter is generally not adjustable, namely the maximum machining depth of the cutter is not adjustable. The length of the blade exposed out of the cutter bar is the conventional length, so that the blade can adapt to most machining conditions, but can not machine deeper grooves with special designs, and the application range is limited to a certain extent. If the length of the blade exposed to the cutter bar is simply increased, the strength of the cutter bar must be increased or a smaller amount of cutting work must be performed during machining because the torque applied to the cutter bar is increased. Increasing the strength of the tool holder requires increasing the tool holder size or improving the tool holder material, resulting in increased tool holder cost or a tool holder that is too large to machine the inner bore slots of smaller bores. The use of smaller cutting quantities during machining reduces the machining speed and affects the efficiency.
ZL201120210803.1 discloses an inner hole grooving cutter, wherein the cutter rod and the cutter blade are designed into a whole, namely, a cutting edge is ground on the cutter rod. Obviously, the maximum processing depth of the inner hole slotting cutter is not adjustable.
ZL201611204828.4 discloses an inner bore groove cutting tool, wherein the blades are detachably mounted on the tool bar, but the length of the tool edge exposed out of the tool bar is not adjustable, and the maximum processing depth is not adjustable.
