Lapping rods M.M.®

Immediately shape your rods in all form, from patented M.M.® preliminary shape containing no abrasive.
lamplan rodagepolissage supports rodoirslapidoirsApplications

For internal and external lapping, and super finishing of spherical, conical and cylindrical parts and many other shapes.

The solution

LAM PLAN offers an original, functional and adapted solution; it responds to the requirements of surface conditions difficult to attain with tools or grinding wheels. LAM PLAN delivers its rods in preliminary shape condition. The user finalises the form of his choice.

A fast machining using common tools (never a grinding wheel) allows adapting the rods to the shapes of the parts to be lapped and then proceeding with the lapping- polishing ion machines or manually in some cases. This technique is possible thanks to the LAM PLAN M.M.® which combines rods and free diamond abrasives.

The technique

The LAM PLAN M.M.® rods consists of two different materials in terms of mechanical, physical and resistance characteristics. The composition and arrangement of the two components associated with the usage of specific diamond abrasive is the base of the patented LAM PLAN M.M® system and its effectiveness.

The advantages of the LAM PLAN M.M.® system associated with Bio DIAMANT®

The LAM PLAN M.M.® system uses special abrasives. A chemical binder allows homogeneous, stable distribution of calibrated diamond grains, while preventing any settling phenomenon. As soon as the rod starts rotating under the effect of the applied pressure and the passage on the two different materials, the diamond grains move and fix alternatively. This causes a phenomenon of significant acceleration of these particles ensuring a high stock removal. Penetrating very low and for a very short time in the rod’s metal mass, each diamond particle always presents an edge opposite to the part to be machined.

All the cutting edges work under an over speed. The abrasive’s efficiency is therefore better and more sustainable.
In addition, thanks to the use of diamond, the rod coating does practically not wear out (good behaviour in terms of shape or inherent flatness).
The LAM PLAN type M.M.® lubricant vaporised in a very small quantity allows cleaning the diamond’s cutting edges loaded with metal waste and operates cooling action.
The small quantity of lubricant significantly reduces the “machining sludge” volume. The work is cleaner and produces less waste.

Qualities

In order to obtain surface conditions varying from 0.2 to 0.01 micron/Ra, LAM PLAN proposes various types of rods. The distribution of the 2 materials which make up the patented bi-component rods type M.M.® remains constant, regardless of the shape given to them. The rods type 2000 are mono-components. They benefit from the quality of bi-component materials, but their efficiency is lower and their wear more rapid.

Rods M.M.® shape B

Our Shape B rods are composed of a 5 mm active part fixed to a steel* ensuring great rigidity. Please contact us for dimensions above 200 mm. To machine the rods and use them, the shapes A or B must be tightened in a mandrel one turn mounted on a metal rod (by tapping or gluing).

NOT: The tapping must always remain below the steel* thickness in the case of shapes B.
In any case (shapes A or B), the centre of the coating has to be cleared to avoid the dead point. During shaping, it is recommended to recover the chips and dusts to reduce the cleaning time.

Expandable cylindric rods

The formula for the accuracy of borings.

The set is composed of:

  • A conical shaft to be mounted on the mandrel.
  • A cast iron rod with pinched structure. A helical slot allows the expansion while maintaining its geometric shape. The rod’s interior is conical in order to receive the shaft.
  • A tube-shaped pushrod is here allows driving the rod on the shaft.
Procedure

The abrasives to be used with the rods is selected according to their tasks:

  • Important stock removal: diamond dosing stick M.M.132
  • Super-finishing : diamond dosing stick M.M.142 or 144

Lubrication thanks to the M.M.712 fluid.
