Fixed Center Heads

Fixed position multiple spindle heads with drilling, reaming and tapping capabilities

                                
A standard heavy-duty automotive style fixed center head is shown. This head is designed for long, dependable service by utilizing several different options.

   •  Heavy-duty construction to withstand rugged operations and continuous use. 
   •  Double oil seals with an air purge to keep the oil in and contaminants out
   •  Oil seal contact areas are ceramic coated on spindles to help dissipate heat
   •  Pre-loaded angular contact ball bearings are used with a sufficient spread between thrust bearing and
      radical bearing for rigid and accurate support of the spindles
   •  A lube pump pumps oil to the top of the head where it is dispersed by oil tubes or centrifugal force and
      cascades down to lubricate the bearings and gears

As with all of our designs special customer requirements can be accommodated;
   •  Customer center distance specifications
   •  Mounting to various drill and tap machines at various angles
   •  Placement of the input drive shaft
   •  Input to output ratios of the head to accommodate the customer's specified tooling
   •  Gear construction to be either spur or helical

  
                                                    



Lead Screw Fixed Center Tap Head

The lead screw tap head shown allows for long service, accuracy and ease of changeover with its design

The design of the lead screw and nut allows for the entire spindle assembly to be removed and replaced for easy changeover.

Placement of the seal in the assembly keeps contaminants out, protecting the lead screw and preventing down time and replacement.

The spindle design also prevents jamming in either the full forward or full reverse positions.

High Speed Fixed Center Drill Head

The high speed head shown is used where high speeds and accuracy are required (300 to 8000 rpm)

High speeds create a major heat source where the seals contact the spindles. This heat source can be eliminated by the use of a stand pipe and slinger to keep the oil in the head.

A cartridge style gear pump is used to pump the oil because of its small size and ease of changeover.
