Zagar MQ-150 Feed Unit with Multi-Spindle HeadApril 1, 2012
Zagar Inc. has introduced an updated version of its Model MQ-150 feed unit.
The redesigned unit is a full servo driven ball screw feed design that incorporates the feature of having the quill and spindle assembly located inside a pre-drilled, precision bored ball screw. The new "in-line" design provides a stroke repeatability of +/- 0.0001", according to the company.
The MQ-150 feed unit can be used with standard tooling to provide single drilling, tapping, counter boring and reaming operations. It can also be combined with a Zagar Multiple Spindle Head to increase productivity and perform these types of operations on various part locations with one feed unit stroke. With 5 HP brushless servo motors and a 6 inch stroke, the Model MQ-150 provides 2,000 lbs. of thrust using a 2.17" diameter quill. The spindle has a maximum of 10,000 RPM with a rapid traverse of 800 IPM. Most common spindle nose adapters can be used from a collet chuck holder to HSK type tool holders.
The Model MQ-150 has its own enclosed control cabinet built to NEMA 12 standards. Brushless servo motors are used for feed rate and RPM control. User friendly software provides easy operator use to input spindle stroke, feed rate, RPM and drilling or tapping sequences, the company said. The built-in PLC is compatible with multiple auto cycling and automatic changeover between stored machining sub-routines. The software provides for peck drilling cycles, rigid tapping, left- or right-hand drapping cycles, which are a combination of drilling and tapping. Adjustable feed and retract stops are provided.
The new Zagar design provides for coolant through the spindle at up to 1,500 lbs. of pressure. The unit can be mounted in a vertical or horizontal position or at an angle. The MQ-150 can also be provided with a quick change, ball lock mounting plate for easy changeover to various part applications, the company said.
The new MQ-150 feed unit can be purchased with its own column-mounting option to form a single or multiple spindle drill/tap station, or it can be used for in-line and rotary transfer type of high production machines.
