The VMC Machine Spindle Cartridge is a belt-driven spindle unit designed for high-precision and reliable machining applications. Its specially engineered belt-drive system maintains spindle nose accuracy strictly below 0.007 mm for consistent machining performance. The spindle unit is available with BT-30, BT-40, and BT-50 nose configurations to suit different VMC machine requirements.
It is suitable for a wide range of machining operations, including drilling, tapping, milling, boring, facing, reaming, and countersinking. Different bearing arrangements, RPM ratings, and dimensional configurations are available for manual and gripper-type applications. The robust design provides dependable performance and precision for demanding CNC machining environments.
Belt-driven spindles are a popular choice and make up a large percentage of spindles.Specially designed with belt driven, the accuracy of spindle nose is strictly under 0.007mm.Spindle unit allows to perform all types of machining applications such as drilling, tapping, milling, boring, facing, reaming and countersinking.| Type of Nose | RPM | Bearings | A | B | C | D | E | F | G | H | I | J | K | L | M | N | O |

Precision-engineered CNC & VMC machine toolings and accessories designed for reliable performance, accurate machining, and efficient industrial operations.
A jig’s primary purpose is to provide repeatability, accuracy, and interchange ability in the manufacturing of products. A jig is often confused with a fixture.
We make multi Head Spindle for the purpose of more than one hole at single operation at different P.C.D. as per your requirements with grease or oil.
The surface of metal parts worked through turning, reaming or boring operations is a succession of “PROJECTION or PEAKS” and “INDENTATION or VALLEY” when microscopically examined (see fig. 1).
The VMC Machine Spindle Cartridge is a precision belt-driven spindle unit designed for reliable and accurate machining performance. With spindle nose accuracy strictly maintained below 0.007 mm, it supports a wide range of machining operations.
The CNC Machine Spindle Cartridge is engineered for high precision, reliable performance, and long service life in CNC machining applications. Precision-ground components, high-accuracy bearings, and special lubrication ensure smooth and consistent spindle operation.
