For New Customers
Nakanishi, Manufacturer of Compact Motor Spindles
Nakanishi is a compact motor spindle manufacturer specializing in high-speed rotation technology.
We manufacture high-quality products with 90% in-house production rate and Made in Japan quality.
What Is a Motor Spindle?
A motor spindle is a device that combines a spindle and a motor. To rotate cutting tools such as drills and end mills at high speed, stable rotational performance, sufficient torque, and high precision are required.
Nakanishi motor spindles that achieve these functions are mounted on lathes, machining centers, robots, and special purpose machines.
They are used in a wide range of processes, including drilling, milling with end mills, grinding with wheels, and deburring with carbide cutters and brushes.
Features of Nakanishi Motor Spindles
Nakanishi motor spindles specialize in high-speed rotation, high precision, and compactness.
High-speed rotation
- They provide the optimum peripheral speed for
small-diameter tools that require high-speed rotation. - High feed rate is possible, which reduces processing time.
High precision
- Spindle accuracy is within 1 μm.
- High-precision processing is possible with small-diameter tools.
Compact
- They can be installed in narrow spaces.
- They contribute to downsizing of equipment.
- They can be mounted on robots with small payloads.
