Rotary Current Spindles

Technical Data

Rotary Current Spindles, Generally

	See table for nominal power, rotational speed and chucking capacity
	Tool change: manual with special wrenches or with pneumatic cone change (see table)
	Software-controlled frequency converter with monitoring functions (temperature, overload etc.) and status indication via LEDs
	Compressor cooling unit for protecting the spindles from overheating under high load (see table)

Requirements

Please note that you need a dry and oil-free compressed air supply for all rotary current spindles with pneumatic tool change or blocking air. You will need a constant pressure of 6 bar. The air consumption of the pneumatic tool change can be disregarded, the consumption of blocking air amounts to approximately 100 to 150 litres per minute. Depending on the whole equipment of your CAM system, it is possible to choose between different types of compressors. Several questions may lead you to the right model: how high is the consumption of blocking air, is there a cooling/spraying unit or a pneumatic tool change, how long are the hoses, what is the maximum noise level of the compressor?

The spindle types SPC 2300P, SPC 3800P, SPC 5500P and SPC 6000 will be delivered with a frequency converter which has to be installed in a 19 inch system rack. The spindle type SPC 2300P will be delivered with an extra compressor cooling unit. For the installation of these components, an appropriate 19 inch system rack is required.

System racks can be found here.

Suitable Machine Lines

These rotary current asynchronous motors are due to their high torque very well suitable for powerful milling works with bigger tool diameters in plastics, wood and metal. Maximum rotational speeds of up to 40,000 RPM allow high rates of feed even when you are using medium tool diameters. As standard we offer rotary current spindles with up to 6 kW nominal power respectively 12 kW maximum power.

Powerful rotary current spindle SPC 3800P with pneumatic SK 30 cone change.

A tempered and grind sleeve shaft with several bearings guarantees high precision. So even fine engravings can be done. The intelligent controller enables constant rotational speeds, even when the load is changing. On top of that, the spindles are fully software-controlled and integrated into the safety concept of the CAM system.

SPC 2300P with pneumatic WK 19 cone change.

All P models have a pneumatic cone receptacle which is a prerequisite for an automatic tool change. Thus your machining process can go on in a highly automatized way.

Appropriate tool change devices.

SPC 1000, the smallest rotary current spindle.

Power pack: SPC 6000 with 6 kW nominal power.
