Profile

Capital Engineering Corporation ourselves as one of the leading manufacturers of wide range of precision spindles and spindle motors from diameter 25 mm to 350 mm, speed up to 1 lakh RPM and length up to 1 meter. The range of precision spindles covers the following : -

1) High frequency spindles.
2) Motorized spindles.
3) Belt Driven spindles.
4) Tool post grinders/ Grinding Attachments.

APPLICATION OF SPINDLES

All types of grinding operations, high speed turning and boring heads & milling heads for CNC, automatic and manual machines. On high frequency spindles we have option to control cutting speed by means of electronic A/C drive and there is no vibration due to inbuilt motor. Motorized spindles are also having built in motor where low RPM is required. Belt driven spindles are having low cost option to get desired RPM by changing different dia pulleys. The precision spindles are manufactured in standard models and also as per the requirements of customers.

We are a team of qualified and experienced professionals from Parishudh Machines Pvt. Ltd. and ABRO group. These organizations are pioneers in precision grinding machines and dynamic balancing machines respectively. The manufacture of spindles was started in 1992. Complete satisfaction of the customer has been our prime motivation based upon rigid quality requirements as per international standards. Based upon these parameters we have designed and manufactured more then 300 different types of spindles. Thousands of our spindles are in operation all over India.

REPRESENTATIVE LIST OF INDIAN CUSTOMERS NBC,

Hero Honda, Eicher, Escorts, Goetze, LPs, Hi-Life, Raunaq group, LML, Ministry of Defence, Aerospace Industry, Government research Center, Tool Room etc.

EXPORTS

Due to our quality standards our spindles have also been approved in European market and we are getting repeated orders from International market.

In addition to manufacture of precision spindles, we also undertake repair/ modification of spindles. We also manufacture diaphragm chucks and other tooling for engineering industry. We are enclosing a copy of catalogue of our spindles for your reference.

INFRASTRUCTURE

Capital is manufacturing precision motorized spindles for over 15 years. We emphasize on quality, accuracy and on-time delivery that makes Capital's Spindles the best choice for your production needs.

We specialize in precision fitting custom built AC Induction motors to the spindle shaft. Precision balancing of these units provide high accuracy and high-speed capability. A temperature controlled assembly and inspection area are state-of-the-art coordinate measuring machines.

HORSEPOWER HEAT DISSIPATION
Motor horsepower (HP) is a function of the size and the RPM of the motor. The larger the motor, the greater the horsepower at a given RPM.

Motors that cause greater heat loss can be cooled with a fan that blows air over the motor. These motors are classified as TEFC (totally enclosed fan-cooled.) When even greater horsepower is required in a smaller package, TELC (totally enclosed liquid-cooled) motors put to application. These motors are cooled by circulating liquid around the motor.

Capital has several years of experience in the design and application of precision motorized spindles. For more information you may contact us.

VARIABLE FREQUENCY DRIVES
Capital supplies motorized spindles for any speed up to 75,000 RPM. To operate at speeds other than 900, 1200, 1800 or 3600 RPM, a variable frequency drive is required. Variable frequency drives must be carefully matched to the motors they drive. Motors and variable frequency drives have pre-determined volts-to-hertz ratios, and these ratios must match for a successful application. Speed control can be integrated into your machine control for ramp-up, ramp-down and adjustment. This can be included in your machine program code or as an electrical control switch or dial.

SPINDLE LUBRICATION
High speed spindles require special bearing lubrication. Capital's air/oil lubrication systems inject precise amount of oil at controlled intervals for optimal bearing life and minimum heat generation. Utilizing only fractions of a drop per cycle means no environmental oil mist concerns. In addition, high air pressure is used to provide maximum protection against contamination of the spindle.

QUALITY

Capital has installed latest and ultra modern automatic equipment that are run and maintained by well experienced staff who produce controlled quality material with the ISO standards. We are fully equipped with electronically operated testing instrument such as micrometers, callipers, all standard gauges, electronic vernier callipers, profile projectors and many other products of approved standard. With these equipment it has become possible to maintain accuracy and desired precision sizes as per requirement of our valued customers. We stand 100% guarantee with the quality.
