Drill Tapping Machine
- Multi-station rotary transfer reaming and drill tapping machine
- Controlled by 8-axis PC-Based CNC system
Six station drill tapping machine processes ½” though 2” couplings from tubing, including auto load with dual tubing feeder and cut-off saw; ream, face and chamfer; and tap.
- Multi-station rotary transfer drill tapping machine
- Controlled by CNC and enhanced diagnostic system
Union nuts, couplings and high-pressure welded fittings are machined in sizes ranging from 1/2”-14 NPT and 3-1/2” – 10 NPT at rates up to 1,350 parts per hour on the 1/2” fittings.
This Kaufman CNC Model KMC-1124 Reaming and Single Point Threading Machine includes eight two-jaw self-centering chuck assemblies positioned on four locations around the dial plate. Each of the three machining units featured dual heavy duty block type boring spindles mounted to independent rectangular hardened way-type slide assemblies and vertical columns. The machine processed a variety of cast Brass valve components in cycle times ranging from 12 to 14 seconds at two parts per cycle. The machine performed precision boring and single point threading operations utilizing CNC Drawbar actuated feed out heads. The machine featured Kaufman’s PC based CNC system controlling both Hydraulic Servo and ballscrew type units.
This Kaufman Model 10ER-24B CNC Filter Plate Tapping Machine includes sixteen interchangeable part nests located in four stations around the dial plate. The machine is equipped with two working stations comprised of a 10ER-2 Tapping Head with a 4 position multiple spindle head assembly, and a four spindle wire brush station to remove burrs from the threads. Parts are automatically loaded into the machine from a bulk type centrifugal feeder with elevator type hopper into a vibratory feed track and escapement assembly. A CNC controlled pick and place unit transfers four parts simultaneously into the part nests and they are automatically ejected into bulk containers upon completion of machining operations. The machine produces over 2300 filter plates per hour.
Roof Mining Bolts
