Valves
- Kaufman flexible CNC multi-station rotary transfer manufacturing system
- Controlled by 27-axis ball screw CNC with B-axis pallets
Cast iron and stainless steel butterfly valve bodies ranging from 2” to 6” diameter are machined on a six-station system. Bodies are precision drilled, tapped, seated, back chamfered, and finished bored using CNC U-axis controlled crossfeed head.
Let’s discuss your machine tool needs
Valve Body
- Hybrid multi-station rotary transfer manufacturing system to machine complete a family of cast iron valve bodies at 2 parts per cycle, at a rate of up to 308 parts per hour
- Controlled by a 14-axis, PC-based CNC system with a combination of ball-screw CNC and hydraulic servo-controlled CNC
Watch this CNC-Controlled Machining Center in Action
This Kaufman CNC-controlled machining center is capable of producing a family of cast iron valve bodies at 2 parts per cycle, at a rate of up to 308 parts per hour. This video shows it in action at a customer location.
Pipe Fittings
- Multi-station rotary transfer drilling and tapping machine
- Controlled by CNC and enhanced diagnostic system
Union nuts, couplings and high-pressure welded fitting were 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.
Brass Fittings
This Kaufman CNC Model KMC-1124 Reaming and Single Point Threading Machine included 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 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 ball screw type units.
