Zagar Inc. has been manufacturing drilling and tapping equipment in the United States since its' first multiple spindle head in 1938. Recently, they introduced an updated version of their most popular feed unit, the Model MQ-150.
The redesigned unit is a full servo driven ball screw feed design that incorporates the unique feature of having the quill and spindle assembly located inside a pre-drilled, precision bored ball screw. The new "in-line" design provides what is thought to be one of the most accurate feed units on the market, having a stroke repeatability of +/- 0.0001".
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 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 1500 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 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.
