Working Head<\/p>\n\n\n\n

\n

Adopting NN spindle design. It can provide high loading capacity, with internal positive pressure to keep the waterproof design to provide the best rotational accuracy and high rigidity, coupled with the use of servo motors in the drive, in the process of grinding, constant speed and constant torque, long time use can show its superiority and long service life.<\/p>\n\n\n\n

High Rigidity Bench<\/p>\n\n\n\n

\n

The lower slide plate always stays on the full support design of the table regardless of the leftmost or rightmost position, utilizing high rigidity Meehamite cast iron and box rib structure. As the root of the stability of the machine, it is burnished and aged to ensure the stability of the material, and the final precision is confirmed by grinding and knurling so that the product presents the best state no matter in the life or the rigidity. z Axis rail adopts a V and a flat design, and the rail support plate is connected with the rib plate of the table so that the stress can be transferred effectively, and the rail can be less deformed. z Axis rail adopts a V and a flat design. z Axis rail adopts a V and a flat design. z Axis rail adopts a V and a flat design. z Axis rail adopts a V and a flat design. z Axis rail adopts a V and a flat design.<\/p>\n\n\n\n

Standard - High rotational accuracy Perrin-type spindle, in addition to a combination of<\/p>\n\n\n\n

In addition to the features of environmental protection and low temperature rise, the replacement of new products is easy and fast.<\/p>\n\n\n\n

Optionally equipped with one-axis bearing, dynamic alloy bearing, fast cutting ability and best surface roughness realization from SNCM220.<\/p>\n\n\n\n

High-grade alloy steel, normalized and straightened, carburized and deep-cooled, and ground and mirrored, the spindle surface hardness reaches HRC62 degrees, and the grinding precision is high without wear for a long time.<\/p>\n\n\n\n

X-axis feed slide<\/p>\n\n\n\n

\n

Unlike the design of other manufacturers, the feed axis adopts the double-v slide rail design, which makes the product present the best balance support and the most stable state. It ensures the perpendicularity of the Z-axis direction for years of use.<\/p>\n\n\n\n

tailstock<\/p>\n\n\n\n

The addition of a water jet above the headstock shows that Promise cares about every detail. The air floatation device provides customers with less effort when moving and reduces damage to the rotary slide. Option - Tailstock with 75mm stroke for easy access to larger pinhole workpieces and oil bath design to ensure smooth operation, in addition to a shorter tailstock with exposed tailpipe to greatly increase the rigidity of the tailstock. An optional tailstock with adjustable taper design to facilitate the operation of personnel to adjust the taper.<\/p>\n\n\n\n
