Multiple and Single Spindle Production Drilling and Tapping Stations

Featuring Zagar gearless multiple spindle drilling or tapping heads that are designed and manufactured at our plant in Cleveland, Ohio. Get ahead of high volume, hole making production demands with multiple spindles. Literally, multiply your production rates by putting more spindles to work. Each multi-head is engineered to meet your requirements for the precision machining of holes in mass produced parts. Drilling, counter-sinking, reaming, and tapping are typical operations. Combination drill – tap tools (draps) are often used to machine patterns of tapped thru holes from solid, in a single pass. Using standard taps, multiple hole patterns of different size and pitch, blind or thru tapped holes, are tapped at the same time by applying Zagar individual lead screws. In a recent project, a multi-hole pattern of blind tapped holes are drilled, counter sunk, and tapped with Zagar multiple spindle stations that feature automatic tool change. (see Zagar YouTube Channel) Complete accessories are available with each drilling or tapping station that are often overlooked or unavailable from other multiple spindle head manufacturers. Supportive guide bars, mounting brackets, fixturing options including self-clamping bushing plates and turn-key modular work piece locating and clamping hardware, are all key factors in successfully applying automatic drill-tap stations in production. In turn, all these factors are evaluated by Zagar Sales & Engineering personnel based on the parameters of your requirements. Whether machining one hole or multi-hole patterns, Zagar Inc. has the experience and in-house product lines essential to engineering and building a production hole making station that is the most efficient and productive solution to your hole making requirements.

Feed Units & Machinery

Zagar Inc. also manufactures a standard product line of automatic quill feed units in our Cleveland, Ohio Plant. There are three types. One is air/oil actuated with electric spindle motors ranging from ½ to 10 HP that are generally applied to drilling stations. A second is lead scew actuated with electric, reversing brake motors that are applied to tapping stations. The third and latest product line are ball screw actuated, CNC quill feed units ranging from 1 to 15HP that apply to both drilling and tapping stations. The CNC units feature precision ground, ball screws that are on the centerline of the spindle. Turnkey control systems are available for controlling single or multiple units. PLC Based systems are applied to air/oil and lead screw tapping systems. Full CNC standard or customized systems are supplied with HMI panels for use with ball screw actuated units.

Applying its own in house components, Zagar offers Standard and Custom Production Machines for drilling and tapping holes. All machines are engineered and built at Zagar Inc. in Cleveland, Ohio. Standard machines include single spindle and multiple spindle drilling and tapping stations in vertical or horizontal configurations. Custom designed or special machines are available with multi-stations and rotary or linear transfer of the work piece. Turn-key options include automatic fixturing, automatic material handling (work piece load and unload) recirculating coolant systems, chip handling systems, and machine enclosures. All machines include production of sample parts and conformance to SPC requirements when applicable. Machines are currently designed in 3D using Solidworks. Free viewing software is available that enables concurrent customer participation in the engineering process. Contact us soon. We’d appreciate the chance to talk with you about how Zagar can supply the best and most productive solution to your hole making requirements.

Workholding Collet  Fixtures & Chucks
Workholding Collet Fixtures & Chucks

Zagar Inc - Wrokholding Collet Fixtures & Chucks

Work holding is fundamental to any machining operation. Zagar collet fixtures both accurately locate and clamp work pieces at the same time. Steel housing components enable operation either hydraulically or pneumatically. More clamping force per square inch is applied on a work piece than any other method of clamping. Cycles are fast and safe. Fixtures are designed for use in severe environments. Bar stock, chips, and coolant can pass straight thru the fixtures. Set-up is made easy with a precision locating boss on each fixture's base.

Customize pallets are available for mounting groups of fixtures used in multiple part machining operations on CNC machines.

Standard fixtures and collets range in size from # 3-C to # 44-C with round, square, hex, or custom I.D.'s Up to 5.5" O.D. Bar stock can fit thru our largest standard fixture and collet.

Zagar collet fixtures are also used as draw-bar actuated rotating chucks as shown. In turn, Zagar automatic indexing fixtures are the fastest on the market. Indexing a work piece around it's center line in zero point two seconds.

Keep us in mind the next time you're thinking about a work holding requirement. Please give us a call. We've been in the business of supplying work holding solutions since 1938 and some of our original collet fixtures that we built back then, are still in use.
