HG-N

Product catalog summary

Overview: The document provides technical specifications and operational guidelines for SMW-AUTOBLOK's HG-N series manual chucks, which feature a quick jaw change system. These chucks are designed for high-speed operations with a flat gripping force curve and are compatible with various jaw types.

Specifications:

Chuck sizes range from 160 mm to 630 mm in diameter.
Jaws can be changed in less than one minute, enhancing operational efficiency.
The chucks are universal, allowing radial adjustment and reversal of jaws, reducing the need for multiple jaw sets.
Maximum gripping force is achieved using the maximum allowed driving torque, with measurements taken using hardened standard stepped monoblock jaws type GST.

Safety and Maintenance:

When using taller or heavier jaws, or clamping at more external positions, it is advised to reduce driving torque and rotating speed to prevent damage.
Regular maintenance using SMW K05 grease is recommended to ensure optimal performance.

Technical Data:

Chucks are available with various mounting options, including DIN 55026, DIN 55027, and DIN 55029.
Key dimensions and technical data are provided for each chuck size, including swing diameter, master jaw thread depth, and usable jaw stroke.
Maximum speed and gripping force parameters are specified for each chuck size.

Additional Features:

The wedge bar design ensures high precision, concentricity, and repeatability.
Safety features include a safety jaw release with interlock and a safety pin indicating correct jaw stroke position.

Accessories:

Various jaw types are available, including soft top jaws, wide soft top jaws, soft monoblock jaws, and hardened stepped monoblock jaws.
A lubrication set is available, including a grease gun and special grease for manual and power chucks, which is essential for maintenance and safe operation.

Catalog excerpts

Chuck takes same jaws as KNCS-N For highest speeds Flat gripping force curve 180 ■ Jaw change in less than 1 minute FG total gripping force (3 jaws) (kN) ■ The max. gripping force is the total, acting on the 3 jaws, obtained by applying to the chuck the max. allowed driving torque. The data refers to a chuck newly maintained accordingly to their service manual, using SMW K05 grease. 260 240 220 ■ Universal, because jaws can be radially adjusted and reversed = less jaw sets FG total gripping force (3 jaws) (kN) ■ The dynamic gripping forces have been measured using hardened standard stepped monoblock jaws type GST placed in a position not exceeding the outer diameter of the chuck. Jaws radially adjustable 19E Safety advice / danger of damage: When using taller / havier jaws and / or clamping on a more external position reduce driving torque / rotating speed accord
