Chucks and Chuck fixtures

Power Operated Eccentric Compensating Chuck with three / two retractable jaw chuck permits shafts, bars, forgings to be machined full length in one set up, centre to centre. In the first operation the component is gripped on the jaws. In the finishing operation the jaws are retracted and the component is driven by the face driver and OD is machined. The special jaws are designed to clamp the component as close to the centre to avoid distortion of the component and provide inconsistent gripping. Eccentric Compensating Chuck with Retractable Jaws and face drive (PER) is used for machining forgings and black bars between centres in single setup, (i.e.) no second operation necessary. This Chuck is designed to machine components centre to centre with great accuracy. The retractable jaws are actuated by a hydraulic cylinder or an also centre to centre, since the jaws have an eccentric clamping drive. After various machining operations are done on the component, without stopping the machine the clamping jaws are retracted. The torque is then transmitted through the face driver for driving the jaws. The gripped portion can now be finished with fine depth of cut. This ensures that the component is machined right upto the chuck face and the centre to centre machining of component is completed. The chuck body is made from forged medium carbon steel and toughened. The levers and hinge pins are made from nickel chrome steel, case hardened and ground in all working surfaces. The hard jaws are made from low carbon steel, case hardened and ground. The special jaws are designed to clamp the component as close to the centre to avoid distortion of the component and provide inconsistent gripping.

6 jaw accuracy self centering tru chuck are mainly used to grip round machined or unmachined job having thin wall like pipe etc.. The job is not damaged as the gripping pressure is divided on six sides.One set of reverse jaws, Mounting Bolts, Operating Key & Inspection Report is provided with each chuck.

Hydraulic Chuck Standard: Ideal tool holders for high-accuracy machining processes such as drills, reamers, ball mills, end mills, and so on.

Hydraulic Chuck Super Slim: These tool holders are ideal for precision finishing processes in small spaces. Interference is eliminated by the slim design.

Hydraulic Chuck Jet Through:  It is Ideal for finishing applications that require improved coolant delivery.

Features:

Power Operated Chucks without through bore can be used as a replacement for manual chucks on a conventional lathe to increase the productivity.

These can be actuated by hydraulic, pneumatic or electro- mechanical actuators.

The actuating unit imparts a linear motion of the wedge is transformed to radial movement of base jaws.

This transformation provides a mechanical advantage of 1:4. This ensures a minimum of 1:2 mechanical advantage after providing for internal losses, self locking effect and losses in gripping power at high speed.

Description & Features:
The Our 3-Jaw Grip Right Chucks (Grip Right Chucks even though not meant for heavy duty work, it is sturdily built. The chucks have a semi-steel body made of tensile cast iron with hardness between 180 and 220 BHN, or of forged steed.
The scroll plates are made of high quality heat-treated carbon steel.
The Grip-Right Chucks have a unique taper locking device between the cover plate and chuck body which allows adjustment of the chuck centre in relation to the machine spindle centre. This features allows elimination of errors caused by inaccuracy of the machine spindle or of the Chuck
