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