Structure of DSP09, 11, 16

Motor installation

Install the DSP on the spindle and the spindle head integrally, remove the screws and fixed blocks and then install the spindle lock nut. After that, the whole is auto- matically installed in place.

Motor removal

Lock the fixed block in place with screws, remove the lock nut of the spindle, and then remove the lock screw of the motor. After that, the whole is removed.

Figure 1: Part processed by belt machine tool (this photo is taken when magnified four times)

Figure 2: Part processed by DSP motor machine tool (this photo is taken when magnified four times)

Description of comparative processing

With the same processing program, tool, fixture, machine tool parameters, the processed part is 304 stainless steel, the processed surface is curved, and the surface roughness is set to 0.4.

Figure 1 shows the part processed by the belt machine tool with obvious chatter marks on the surface.

Figure 2 shows the part processed by the DSP machine tool. Its surface is smooth and free of chatter marks, which proves that turning instead of grinding can be achieved.

CARE about the Concerns of Machine Tool Users

·Lower operation and maintenance costs, higher reliability

No belt structure and consumable parts. Easy to disassemble and replace. Almost maintenance-free.

·Smaller space required, more composite applications

Greatly simplify the mechanism, make the machine tool miniaturized and multi-spindle, while bringing more abundant, more silent, and more composite functions.

·Higher parts precision, more stable performance

The precision and finish of parts are better, the roughness can reach 0.4−0.8, and the external heat source leads to more stable precision.

·Faster processing takt, higher productivity

Features of full-field high torque, faster acceleration and deceleration, and servo reduce the workpiece processing cycle and effectively improve the productivity.

·Lower energy consumption

The precise and efficient electromagnetic design and the matching design with the machine tool features lead to a wide high-efficient range, which is conducive to energy saving and consumption reduction.

·Without changing the size of the spindle head, easy to realize the motorized spindle

Externally installed DSP, no change of the spindle head required, keep the original system completely, and realize motorized spindle easily and flexibly.

·Integrated installation, easy to succeed in a few minutes

Integral installation, no complicated adjustment, low labor intensity, high assembly quality.

·Integrated removal and replacement to facilitate after-sales support

Convenient for direct users to replace online and overcome the pain points of built-in motorized spindle.

·Convenient for factory logistics and production management

Compared with belt spindle and built-in motorized spindle, BOM is simpler, requires less labor, and is more convenient for management.

·Respond to and meet the trend

Easily and flexibly realize the miniaturization of machine tool and the multiple changes of spindle.

·More appealing features, helping sales growth

Highlight advantages in the part precision, stability, efficiency, convenience of sale and service, etc.
