CUSTOM BUILT CHUCKS

GMT Chucks for special applications. Guindy Machine Tools provides solutions for all workholding problems, be it cylindrical or non-cylindrical as a result of years of experience. Besides, we also offer special workholding solutions to meet your machining requirement.

Power Operated Eccentric Compensating Chuck (PE)

Eccentric Compensating Chuck is for machining forgings and black bars between center. Besides, these chucks are essentially designed where the component is located between centres. One on the chuck body and one on the tail stock of the machine. more…

Eccentric Compensating Chuck with Retractable Jaw (PER)

Eccentric Compensating Chuck with three / two retractable jaw chuck permits machining of shafts, bars, forgings in full length in a single set up, centre to centre. The jaws grips the component in the first operation. As a result, in the finishing operation the jaws retracts and the component is driven by the face driver for machining OD. more…

Power Operated Pneumatic Front End Chuck (PF)

Power Operated Pneumatic Front End Chucks utilises in full, the spindle bore for bar/pipe work. The actuating cylinder is built into the chuck. Also, this design avoids rear mounting of the actuating cylinder and necessary draw bar connections. Above all, the stationary air distribution system is mounted separately on the chuck. more…

Quick Change Jaw Chuck (PHQC)

Most important fact is that Quick Change Jaw Chuck reduces the change over time of jaws for different components and is suitable for machining small and medium size batches. Also, base jaw, fitted with top hard or soft jaws are pre-turned or ground to suit different components and kept ready. Whenever the component changes, the corresponding base jaw with top jaws may be replaced in a short time. more…

Universal Ball Lock Chucks (UBLC)

GMT Ball Lock Chucks have certain distinctive advantages over wedge and lever type chucks. Sliding and swivel of the base jaws achieves jaw movement, which are of ample proportion. Therefore, this results in less wear, less bearing pressure and less stress concentration in the jaws. Besides the radial clamping forces, these chucks provide an axial force to pull the component against the butting face. There is a positive pull back action against jaw face after clamping due to spherical movement and positive sealing to prevent entry of chips. more…

Power Operated Hand Indexing Chuck (POHI)

GMT make Power Operated Hand Indexing Chuck is ideal for machining valves, bonnet, etc. with intersecting axes. Consequently, it can be machined in single setup. The component clamps between the jaws. Finally, after the machining operation is over, lift the index lever and component with the jaws indexes to the next position. more…

Power Operated Power Indexing Chucks (POPI)

Power Operated Power Indexing Chucks are primarily for machining valves, bonnet, universal joints and spider. Furthermore, integral hydraulic cylinders performs clamping, de-clamping, indexing and locking of index drum. The oil fed to the different cylinders through a pipe bundle running through the spindle bore. more…

Twist Finger Chuck (PW)

As a result of it finger action, Twist Finger Chuck is ideal for clamping the component on face with centralized location, where clamping on OD/ID facilities are not possible. Typical examples are brake drums and automobile hub wheels. more…

Diaphragm Chuck (DC)

Diaphragm Chucks are ideal for thin walled components. Furthermore, these chucks are ideal for light accurate turning, fine boring, facing and grinding operations. As a result, diaphragm chuck improves accuracy. It keeps the concentricity consistent during precision machining operations. more…

Collet Chuck (CC)

Collet Chuck is suitable for machining components like round, square and hexagon with finished gripping areas at high speed. Also, runs on CNC lathes and is interchangeable with GMT power chucks. The actuation of the chuck is by a hydraulic cylinder. Furthermore, it has a compact design and the permissible run out accuracy is as per DIN 6386. It is available in four sizes: 26mm, 42mm, 60mm and 80mm. Also, special application collet chucks are available which are customised to your requirement. more…

Grip Down / Pull Back Chuck (GDC)

Grip Down Chuck is ideal for the finishing operation. Consequently, the Radial pull back function of the chuck ensures: Positive resting of the component after clamping, Parallelism, High gripping force, Repeatability, Suitable for auto components. more…

Expanding Mandrel

Typical application is internal diameter clamping of component to machine in a single setup. Also, maintains concentricity and there is a high clamping force. more…

Other Specials

Besides the above mentioned special workholding, we also manufacture Crank Shaft Machining Chuck, Friction Welding Chucks, Knuckle Fixture Chuck, 1300mm Ø PS Chucks, Facing Heads, Steady Rest Bevel Gear Chuck, Dust Proof Chuck.
