Double Sided Lapping Machine - Kemtech Twin Lap

The Kemet Twin Lap machine is a small but versatile bench mounted machine ideally suited for small workshops and laboratories for double sided lapping. It comes fully equipped and ready to use and is suitable for lapping components up to 114mm diameter and up to 30mm thick. In certain circumstances larger components can be accommodated.

The machine is belt driven and built on a Aluminium extrusion base. Machine feet eliminate vibration transfer to and from the floor. This design gives the operator a shorter reach to the plate and easy access underneath for maintenance. The main lap plate can rotate both directions, and the work holder will automatically oscillate.

The machine will operate with a free abrasive compound such as silicon carbide, alumina or boron carbide, suspended in a oil or water based vehicle or a Diamond Compound. The compound is fed onto the lap plate from a free-standing system via a peristaltic pump.

As with all lapping machines of the double sided lapping type, we recommend that the lap plates are re-conditioned using conditioning gears on a regular basis. The machine can also be fitted with diamond dispensing equipment and special complementary lap plates.

The machines come fully equipped and ready to run. The controls are housed in a single steel console attached to the base frame at a convenient working height. In all cases the lapping operation is controlled by a multi range adjustable timer or optional DTI mode.
