Developed on well-known and proven technological bases, this equipment will perfectly respond to your needs in terms of double-side lapping or polishing of parts with a diameter between 5 and 30 mm.

Capable of integrating LAM PLAN lapping plates, this machine will be the solution when obtaining a geometry and precise dimensions are key factors. In parallel, the possibility of associating the M.M.2380 to polishing supports will enable you to answer your needs when the quality of the polished surface is the decisive criteria, as for example, the optical or watchmaking sectors.

The M.M.2380 is built on welded and bolted steel section frame to guarantee stable and repeatable results. The plates (inferior and superior) and the central gearwheel are driven by “brushless” motors, allowing to regulate the speed and the rotational direction. The plates have a 380 mm exterior diameter and authorise the use of 5 carriers (with a usefull capacity of Ø 125 mm).


and advanced technology

Touch screen control panel

All the machine settings are controlled through a large 10.5 inches touch screen. The design of the Man-machine interface assures an efficient equipment handling. This screen will show the pressure applied on the parts and the motor torque in real time. This machine can also be endowed with a “stock removal measurement” system. Apart from the cycle time, the machine automatically stops its cycle when the target thickness dimension of the parts is reached.

    Technical characteristics
    and equipment

    User-friendly device

    The MM.2380 can be equipped with a system unabeling a rapid setting of the carriers. A “rack” system enables to store many satellites filled by the operator in masked time. The ring gear has a removable part. Thereby once the polishing cycle is finished the operator can proceed to a transfer of carriers by sliding them on a thin magnetic slab. Loading the carriers (filled with parts) in the machine (to start a new cycle) will be done the same way.


    Finally, a series of associated accessories has been developed by LAM PLAN for this machine. The FIXPAD® system associated with the FAS® will facilitate the shift of polishing supports.

    Moreover, LAM PLAN proposes its range of TOUCHLAM® pads, specially adapted to the superior and inferior plates of the machine.

    Available accessories

    • FIXPAD® system

      The FIXPAD® is a tool which permits to install easily and rapidly the polishing cloths on double-side machines.

      Developed by LAM PLAN, the FIXPAD® permits to stick the discs on the plates without imprisoning any air bubbles or causing any folds. Thanks to its conception and the pre-cuts of the TOUCHLAM®discs, the disposition of the discs on the superior plate is made possible in a few seconds. the FIXPAD® centring studs are placed in the distribution hole of the superior plate so they can guide the fixation of the disc. This tool will simplify the installation of the polishing discs and limit the machine stoppage.

    • Stock removal measurement
      10 84003 00

      System permitting to obtain a flat surface within a micron, combined with a high quality parallelism between the lapped face and a reference.

      This device is constituted of a perfectly flat pressure disc translating on a vertical axis. Therefore, it assures a support on the opposite face of the surface to be lapped.

      The guidance of this support plate is realised by a high quality linear ball bearings. Therefore, at the end of the lapping cycle the parts contained in this tool will have a parallelism inferior to 5 microns. The support is ceramic coated, assuring a long life service to this reference surface with no risk of metallic pollution.

      Finally, these tools are equipped with a wireless sensor, allowing to visualise the stock removal in real-time on a computer. The target dimension can be set. Thanks to an intuitive colour display, the operator can rapidly visualise on the computer, when the parts are in the thickness tolerance defined by your specifications.
