Product Description

3MK136H CNC Bearing special internal grinder

Stability, high rigidity

1. Redesign the bed, carriage and other basic components, reduce the center of gravity, increase the length and width appropriately, and increase the stability of the basic components.
2. HT300 material is used for medium and large castings such as bed, carriage and box, QT450-10 is used for medium and small castings, resin sand casting and electric furnace casting.

3. The electric furnace shall be tempered twice strictly to eliminate the internal stress of the casting and improve the overall rigidity of the machine tool.
With built-in motorized spindle

1. The work piece shaft adopts the built-in electric spindle.
2. The grinding wheel shaft of the internal groove machine tool adopts the electric spindle. 

3. Reduce the mechanical vibration and improve the precision of grinding work piece, especially for the improvement of work piece waviness.
Generality

1. The main parts of the machine tool with two grooves and one hole and multi series of the same specification, as well as the general tooling, are suitable for the production of small batch and multi varieties of machine tools.
2. The machine parts of the same series with different specifications are common.
3. Large stroke of carriage sliding table - improve the adaptability and range reservation of the whole machine tool. Through the increase of trapper travel, we can better meet the special needs of customer service, and reserve the processing range of the equipment.
4. Optimization design of main parts Dresser, electromagnetic center less fixture, work piece spindle are redesigned to improve the accuracy. Reduce hydraulic use Loading and unloading, manipulator, finisher components cancel or reduce the use of hydraulic, pneumatic or servo control instead.
5. Filter at the inlet and outlet of the hydraulic station - improve the cleanliness of the oil products and prevent the blockage of the oil circuit from affecting the production.

1. Filter through the inlet of the hydraulic station to filter the impurities falling into the oil products of the hydraulic station. 2. Filter through the outlet of the hydraulic station to remove the impurities produced by the internal system of the hydraulic station.
Internal cleaning of machine tool

1. Install a new device around the bed to ensure that the grinding wheel ash and other wastes are washed clean at any time.
2. Install the cleaning water gun. The control system has a variety of options such as CNC system Siemens 808D, Siemens 828, FANUC Oi, etc., and Mitsubishi FX series, q series PLC can be selected; or other control systems can be improved according to the special requirements of customers.
3.  Automatic protection system of electric cabinet door - it indicates the protection level of electrical components and reduces the possibility of electrical damp alarm.
4.  Informationalization of the whole connection -- through the configuration control of the connection equipment, the production management personnel can simplify the extraction of the required information

1. Information extraction and management of one or several related equipment through configuration software, such as production beat, bottleneck process analysis, machine tool spindle power analysis and production quantity load statistics. 2., the early stage of the future development of information automation plant will be laid down by configuration connection, and the development trend of Internet plus and industry 4 will be met.
