Ltd Company Overview Inovic Engineering Solutions is part of Kaygee Engineering Group with more than four decades of experience in precision manufacturing. Over the years, the company has gone through mass production learning and has designed, developed and produced various precision components and assemblies for leading manufacturers in the Automobile and Aerospace Industries. Since 6 years, Inovic has also started manufacturing precision tooling systems, along with Jig & Fixtures for various industrial applications. The vast expertise garnered to design and manufacture products with a synergetic structure drove the development of Precision Work Holding Systems. Inovic has the expertise to custom design, develop and manufacture innovative work holding systems for your production and automation requirements. Our specialised know-how can help boost your production with higher precision quality and profitability. Importance of Precision Work Holding Systems While selecting a work holding system, the method of holding a part is as crucial as the way in which it is cut. In other words, how a part will be cut often depends on how it is held. An efficient manufacturing process requires good machine selection, proper cutting tools and the right work holding. The first two areas typically receive substantial consideration but work holding is often overlooked. The right work holding selection can increase manufacturing process stability, efficiency and safety. Work holding requirement can be affected by many factors including the material being cut, critical tolerance requirement, workpiece shape and dimensions, and frequency of changeover. Quick change collet chucks is the solution for shorter runs. COMPANY OVERVIEW | 3 Product Range At Inovic, a team of experienced engineers ensure all factors are considered in finding the most suitable work holding system for a specific application thus optimising the manufacturing process. Replacing standard push type steel collet systems with special polymerised rubber collet systems, we offer you flexible and customised solutions Made in India. Inovic provides a wide spectrum of standard and customised solutions. Our NAVI,EVA Mandrel, IKRAN NAVI and IKRAN EVA range of sealed Pull-Back compact chucks with high accuracy can improve throughput and part quality in operations on CNC Turning Centers, Machining Centers, Turn Mill Centers and Indexing Table machines. The range is based on maximum work piece diameter and the size of the spindle nose. The NAVI,EVA Mandrel,IKRAN NAVI and IKRAN EVA work holding systems, along with precision clamping heads and bushings offers various advantages with distinct features in comparison over conventional collet chucks with spring steel colletsand Bushings. Features and Advantages Superior Geometric Tolerances Quick Changeover of Parallel Clamping Pull-Back Action Against with Concentric Precision Clamping Heads Fixed End-Stop < 0.015mm Superior Clamping Force Eliminates Repeated Jaw Improved Cutting Parameters Consistent Accuracy Boring in Conventional with Stability and Vibration and Reliability 3-Jaw Chucks Dampening 4 | PRODUCT RANGE The Clamping Head | Quick Change Collets The clamping heads from Inovic are based on the Rubber Flex principle, integrated by precision-hardened alloy steel segments held firmly by a polymer. This results in minimal wear and tear during machining. The development of the clamping head is derived from a combination of steel & polymer in conjunction with polymerisation, perfected over numerous trials and experience. The clamping heads have a changeover time of under a minute using our Collet Changing Fixture (CCF). Collets are available in various configurations for all types of applications: Types Shapes Sizes Smooth Round TCT-50 Serrated Hex TCT-60 Square TCT-100 with gripping range Custom between ±0.5 mm Smooth bore collets are typically suited for second operation work to protect finished machining. Serrated bore collets are typically suited for first operation work and heavy duty machining. Collets are precision ground to size with total system accuracy < 0.015 mm. Polymer between collet segments provide excellent sealing as well as vibration dampening.

Insert the steel pins into the collet face and rotate the wheel clockwise to collapse the collet. Once the collet is positioned within the chuck body, rotate the wheel anti-clockwise to expand and release the collet. Available in three sizes ( TCT – 50 , TCT – 60 , TCT – 100 ). End-Stops A standard end-stop is used for accurate z-axis positioning of short work pieces. Additional end-stop extensions are mounted on standard end-stops suitable for the workpiece. A depth end-stop has a greater throat depth enabling longer shafts to be inserted resulting in minimal protrusion beyond the collet face. A front end-stop is mounted on top of the chuck face where resting face is ahead of the clamping area. All end-stops are located against a shoulder within the chuck body and are held in place with radially located screws. Base Plates Base plates (Spindle flanges) offer the flexibility to mount collet chucks to a wider range of spindles – Larger chuck with a smaller spindle nose or a smaller chuck with a larger spindle nose. All base plates are hardened to 60-61 HRC and precision ground with overall accuracy < 0.005mm Base plates are available for all chuck sizes and suitable for different spindle nose sizes from A25, A26, A28 and A211. Collet Boring Fixtures Toughened collets are designed to be machined in by the customer to accommodate special sizes, shapes & counter bores. Boring fixture is basically a retaining ring with pins, which holds the collet segments firmly in place and puts the collet under slight compression to ensure accuracy and roundness during machining. Available for collet sizes TCT - 50 & TCT - 60. 14 | ACCESSORIES Testimonials Automotive “We are into the mass production of gear blanks & shafts for the two – wheeler industry. We shifted to the INOVIC NAVI – 60 Combi pull- back chucks in February 2018 for our turn milling, drilling, tapping & boring operations. Since then, we have been getting higher accuracy consistently. The quick change over time & reduced burr clogging has increased our efficiency and profitability. Also no skilled labour is required to do the task.” - Mr. Rajesh Kothari, Vardhaman Auto Comp Pvt. Ltd. Aerospace “We have been using INOVIC NAVI- 50 Standard Chuck since November 2018 on our MAZAK Turn Mill for precision aluminium components used in the aerospace industry. Our rejection rate has been reduced drastically & we are getting much higher consistency compared to our previous collet chucks. ” - Mr. Jitendra Mundke & Mr. Sandeep Raut, CPC Precicomp Pvt. Ltd. Tool Holding Systems “We are into manufacturing of BT40, BT50, HSK precision tool holders. The operations performed on our 5 – Axis ‘MAKINO’ are milling, drilling, tapping & boring. We changed from conventional collet chucks to NAVI 60 combi- pull back chuck & IKRAN 60 chuck in March 2020. We have experienced quicker change over time, increased accuracy and decreased burr clogging with INOVIC chucks.” - Mr. Vipul Chopda, KTA Spindle Toolings Defense & Automotive “We do CNC turning for various precision components like Stub Axles, Knuckles, Wheel Hubs & Defence parts. We shifted from Three Jaw Hydraulic Chuck to INOVIC NAVI - 60 combi Pull-Back chucks with customised special front End-Stop in January, 2020 & have been experiencing greater accuracy & consistency. Since then, the changeover time is much quicker & no boring of jaws is required. Also the rejection rate has been reduced drastically and no skilled labour is required anymore. ” - Mr. Tushar Mengale, Seinumero Nirman Pvt. Ltd.
