New product launch!!!
Handle with cold floating hinge
Precision hinge hole floating guide with floating tool handle with floating tool handle
 In the process of reaming, do you suffer from the following problems:
The size of the hole is enlarged and the dimensions cannot meet the processing requirements
The middle of the hole is big, the two small, the cylinder is not able to meet the requirements
The inner hole surface roughness does not meet the requirements
The reamer is not durable
The straightness of the hole is poor
The consistency of aperture size is difficult to ensure in mass processing

The "floating hinge shank" can be automatically centering to ensure the quality and precision of the processed hole. The use of "floating hinge handle" can effectively reduce the cumulative error, eliminate the radial runout of spindle, the reamer center in the whole process of ream machining always keep up with the processing hole center, make the process more smoothly, thus improve the reaming processing accuracy, extend the life of the reamer. At the same time economize on the calibration, changing the knife and other auxiliary working hours, improve production efficiency, greatly reduce the production cost.
The floating knife handle series produced by our company is of high precision, high stability, high price and high cost performance compared with similar products of various brands at home and abroad. Through customer use verification, processing precision and service life are consistent with the same products of famous foreign brands.


Process analysis
1. Traditional reaming process, the spindle and reamer of machine tool are rigidly connected, and the accumulative error is large. The coaxial degree error of reamer cutting edge and spindle is inevitable. In the process of rotation and centrifugal force of spindle, there must be many undesirable consequences:
1. The actual rotational trajectory of the reamer cutting edge is larger than the reamer diameter and cannot be controlled, so the actual size of the processed hole is large and irregular.
2, as feed, gradually deep hole reamer, reamer and the alignment error of the spindle, rotating centrifugal force was tied to workpiece aperture and degrees of freedom into a direct ratio decreases, and thus the hinge aperture reduced gradually. Form commonly known as "trumpet mouth".
3, under the effect of alignment error and common rotating centrifugal force, reamer point contact such as turning tool, boring tool, cutting tool, the bulge on the trajectory round is only a small blade cutting operation, less than the rest of the blade is cutting the hole wall. This must produce vibrations that shorten the life cycle of the reamer.
4, due to the cumulative error of the rigid connection, rotating centrifugal force, part of the blade cutting vibration, and many other adverse factors work together, so be hinge aperture size precision and shape tolerance and roughness are to reach the ideal effect.
Second, use the "floating hinge handle" reaming process, "floating hinge handle" special structure which can realize continuous internal axial and radial deflection translation, have always been able to cause the clamping reamer center around the spindle center, 360 degrees of easy floating in the vertical plane. Effectively make up for the center of reamer and the deviation of machining center hole, to eliminate the radial runout of spindle rotation due, reamer center in the ream machining process is consistent with the processed hole center:
1. Enable the holding reamer to automatically find the center of the processing hole, automatically adjust the spindle, ensure that the center line of the reamer is parallel to the center line of the processed hole.
2. The spindle of the machine tool can be transferred to the rotating reamer through a floating hinge handle.
A. The reamer completes the hinged task in a flexible, smooth and uniform way throughout the process of reaming, so that the diameter of the hinge aperture, the diameter of the cylinder reaches 0.002 mm, and the roughness reaches Ra0.2 um.
B, main shaft and clamping reamer center in setting the floating range is always keep coincidence with work piece hole center, reamer blade all full uniform and no vibration, which makes the reamer at least can prolong service life of more than 5 times;
C, processing deep holes, the reamer is not wear under the condition of continuous ream, all roundness and cylindricity and roughness of the hole processed honing, grinding of high precision, and can maintain a high consistency. It has achieved the standard of ultra-precision machining, which has removed honing process, improved production efficiency and reduced investment in fixed assets.


Operation method to eliminate the above deviation:
Tighten the adjusting nut. And then we're going to slowly rotate back. Until completely eliminate the axis error of the tool axis and the preprocessing hole center.
When tightening the adjusting nut, the cutter axis will not float Angle. Adjust the adjusting nut, cutter axis can be within the scope of the axial maximum 1 ° to float, Angle varies with the extent of the radial floating floating range increases.
