Concept Engineers, established in the year 1984 by a group of young experienced engineers and technocrates. The very concept and principle of work holding was revolutionised ensuring all the available machine capability be transferred on to the job by the product hydraulic expanding mandrels and chucks.

On-going investment in latest design techniques and state-of-the-art machinery and plant have made us pioneers in this engineering industry.


We Offer
We have earned a remarkable position in the market for supplying superior quality products at reasonable prices and with timely delivery. On-going investment in latest design techniques and state of the art machinery and plant makes Concept Engineers an industry leader. Our range of durable and robust designing products includes:

Multiple Collet Mandrel
Multiple Collet Mandrel

Multiple collet expanding mandrels are unique.Uniform support through out the length ensures sturdy support during machining and better concentrators.Spindle mounted and actuated using machine draw bar.

Application:

Used mostly in the manufacture of automotive cylinder liners and thin walled long tubes.


Hydraulic Expanding Mandrel

Works on the principle of hydrostatic transmission or pressure exerted on a thin walled sleeve to expend very uniformly radially with least runout. Totally self contained and actuated manually using an Allen key.

Application:

Applicable on almost all kinds machine tools, fixtures and gauging devises.
Finish turning, Finish milling, Cylindrical grinding, Surface grinding, Gear hobbing and shaping , Gear shaving, Gear grinding, Gear honing, Dynamic balancing are some of the main field of application.

Hydraulic Expanding Mandrel

Hydraulic Gear grinding mandrels
Hydraulic Gear grinding mandrels

Used for gear grinding application and also gear honing. Since there is no linear moment and only radial expansion the gear is perfectly aligned to ensure a high degree of radial runout.

Features
  • Self contained unit.
  • Rigidity as in single piece construction.
  • Manual actuation.
  • Made out of high grade alloy steel


Gear Grinding Chuck

Manufactured with perfection they guarantee a long life and are used in machine spindle mounting. They are power actuated using machine drawbar. With a runout error on chuck <0.02> they are used for turning ID WRT OD.Contracting chuck with working principle is similar to that of a mandrel.

Application:

Used in gear grinding application to hold shaft type of components.

Honing Mandrels
Honing Mandrels

With the ability to handle critical size control and surface finish requirements, our honing mandrels eliminate alignment issues and multiple setups. They are used on nagal stroke Nissan machines. They have a diameter ranging from 8mm to 40mm and can be custom built according to customers specifications and requirements.

Application:

Used on precision honing machines and nagal stroke Nissan machines.


Gear PCD Runout Checking Device

  • As the name implies Gear PCD Runout Checking Device is used for inspecting the run out of pitch circle diameter of a gear.
  • This is a high precision measuring unit with a repetitive accuracy of less than 0.002 mm.
  • The base, the table, the tailstock and the head are made out of close grained castings.
  • The base is having box structure adequately ribbed for rigidity.
  • Pillar and other ware parts are made out of alloy steel and hardened appropriately.
  • The gear to be inspected is mounted on an arbor [either on a Concept Hydraulic Expanding arbor or on a taper arbor.
  • The arbor along with the gear is in turn mounted between centre of the device.
  • The tailstock could be moved by loosening the knob.
  • Further adjustment can be carried out using knob 2. The gear can be positioned to the centre of the ball by rotating the knob 3. The head 4 can be moved up or down by rotating handle 5 to pre-load the dial. When lever 6 is moved, the dial retracts, the gear is indexed and the lever 6 operated to obtain reading. The operation is repeated to obtain the total PCD error.
  • The dial can move up or down by 10mm.
  • The table can be move in X axis by 100 mm.
  • The head can be moved up and down by 75 mm in Z axis.
  • Centre height 90 mm
  • Admit between centre 275 mm
