LTN-621
IN STOCK!
LTN is a polishing machine for round edges up to 8 cm and flat edges up to 10 cm thickness, born by the need to create an essential, solid and compact machine at an affordable price that is equipped with a high level of automation. The LTN maintains the shaping principle by means of a single cup-shaped diamond wheel for all profiles and thicknesses. The oscillation system is driven by two motors connected and ruled by a single inverter, which allows mechanical simplification, reduced maintenance, high performance and good reliability. The structure is monocoque and self-supporting (not coated and tubular framed). Waste water is piped in a unique collector (it neither falls directly to the ground nor on the bearing base of the machine). All protections are made of strong and safe stainless steel.
a wide range of supplementary automations and accessories available
Dimensions from 4000 x 1900 mm
Power: from 26 Kw
- 1 CALIBRATING MANDREL to gauge thickness at an adjustable depth (max. 100 mm). The mandrel can be adjusted both laterally and longitudinally with respect to its supporting shaft; moreover, it can be rotated from 0° to 90°, and can also be used to carry out slotting for the drip stone. For Ø 250 mm tools.
- 2 OPPOSING MANDRELS INCLINED AT 45° to cut chamfers and/or bevels of various dimensions. Whenever you need to carry out rounded profile edges, these mandrels, thanks to the use of specific diamond cone trunk grinding wheels greatly help the shaping made by the oscillating mandrels to the desired edge shape. For Ø 130 mm wheels.
- 6 OSCILLATING MANDRELS of which the first two are ready to be equipped with cup-shaped diamond grinding wheels in order to carry out the shaping of the rounded profiles or the grinding of the flat, squared off or inclined profiles. The other four mandrels are equipped with polishing and smoothing abrasive grinding wheels. If necessary all the 6 mandrels can be equipped with abrasive grinding wheels. Other models derived from the standard LTN 621, by adding extra functional units, can be built on request. For Ø 130 mm wheels.
- The control panel is easily accessible on its articulated arm.
- The oscillating mandrels are unified, tested on thousands of machines, and protected by a mazelike mechanical system (without bellows). Each mandrel has a hydraulic motor and makes distinct revolutions.
- The mandrel-holding beam is pressurized and works by a lever-and-rod oscillation system (it requires no maintenance and has been highly tested – 1987 MM original patent) and micro-oscillation for flat parts.
- The oscillation system is driven by two motors connected and ruled by a single inverter, which allows mechanical simplification, reduced maintenance, high performance, and good reliability.
- The color, tactile programmer (touchscreen) allows to set the machine quickly and intuitively by choosing various default profiles.
- The positioning of the first self-shaping mandrel is automatic.
- The default programming can be customized and stored.
- It is possible to carry out partial processing and to program distinct advances and delays for the engagement of each pneumatic mandrel.
- The programmer has also the following functions:
- DIAGNOSTICS: to find out any working anomalies and/or failures;
- WORKING STATISTICS: to store quantities according to the types of processing performed (partial, resetting and total counters);
- MAINTENANCE SCHEDULE: it reminds the user the ordinary maintenance to be carried out.
