Johnford 40 taper SV and VMC super vertical machining centers are box-way, geared-head, C-frame machines that feature solid heavily-ribbed Meehanite cast iron construction to eliminate vibration and ensure excellent surface finishes and long cutting tool life. X-Y-Z travels for the 13-machine series range from 32″ x 20″ x 24″ (800mm x 500 mm x 600 mm) to 120″ x 43″ x 32″ (3000mm x 1075 mm x 800 mm).

Four oversized box ways support the saddle and work table, maximizing X-axis accuracy over the full travel range of the machine, a key factor in maintaining part accuracy and precision. All sliding surface areas and gibs are coated with Turcite-B and hand scraped for precise fit.

Large diameter pre-tensioned ballscrews have a double-nut preloaded design to minimize the potential of thermal growth and promote high accuracy and high speed positioning.

Available horsepower for the 40-taper spindle ranges from 15 to 20 hp, depending on the machine, with maximum spindle speeds of 10,000 – 24,000 rpm. The motor and gearbox are aligned to ensure no offset and guarantee steady movement of the headstock along the Z axis. The design reduces torsion on the headstock and ensures optimum rigidity, long term accuracy and repeatability. A two-speed gearbox is standard, with direct/integral drive optional.

A 24-tool capacity arm-type automatic tool changer is standard, with 30-, 40- and 60-tool versions optional. Also standard are rigid tapping capability, a spindle oil cooler, a full machine enclosure and flood coolant system with programmable air blast. A comprehensive list of options includes linear scales, tool setters, probing systems, 4th- and 5th-axis drives and accessories, pallet changers and other equipment to enable a user to tailor machine productivity to a specific manufacturing environment.

Johnford 50 taper SV and VMC super vertical machining centers are box-way, geared-head, C-frame machines that feature solid heavily-ribbed Meehanite cast iron construction to eliminate vibration and ensure excellent surface finishes and long cutting tool life. X-Y-Z travels for the 12-machine series range from 33″ x 20″ x 24″ (838 mm x 508 mm x 600 mm) to 120″ x 43″ x 32″ (3000mm x 1075 mm x 800 mm).

Four oversized box ways (two on the SV-40H) support the saddle and work table, maximizing X-axis accuracy over the full travel range of the machine, a key factor in maintaining part accuracy and precision. All sliding surface areas and gibs are coated with Turcite-B and hand scraped for precise fit.

Large diameter pre-tensioned ballscrews have a double-nut preloaded design to minimize the potential of thermal growth and promote high accuracy and high speed positioning.

Available horsepower for the 50-taper spindle ranges from 20 to 35 hp, depending on the machine, with maximum spindle speeds of 6,000 – 15,000 rpm. A two-speed gearbox is standard, with direct/integral drive optional. The motor and gearbox are aligned to ensure no offset and guarantee steady movement of the headstock along the Z axis. The design reduces torsion on the headstock and ensures optimum rigidity, long term accuracy and repeatability.

A 24-tool capacity arm-type automatic tool changer is standard, with 30-, 40- and 60-tool versions optional. A comprehensive list of options includes an automatic pallet changer, through-spindle coolant, 4th- and 5th-axis rotary tables, and other equipment packages that enable a user to tailor machine productivity to a specific manufacturing environment.

The three-machine series of Johnford SV and VMC twin spindle vertical machining centers are box-way, geared-head, C-frame machines that feature solid heavily-ribbed Meehanite cast iron construction to eliminate vibration and ensure excellent surface finishes and long cutting tool life. The machines offer X-Y-Z travel of 45″ x 21″ x 25″ (1125 mm x 525 mm x 626 mm) to 51″ x 34″ x 28″ (1275 mm x 850 mm x 700 mm). Table sizes range from 48″ x 20″ (1220 mm x 500 mm) to 59″ x 28″ (1500 mm x 710 mm).

Two machines in the series have 20 hp spindles fitted with 40 taper toolholding systems, while the largest machine has a 35 hp, 50 taper spindle. Distance between the spindles is 17″ (425 mm) on the smallest machine and 25″ (635 mm) on the others. Every machine has a 24-tool capacity automatic tool changer, with 32, 40, 60, 80 and 120 tools optional.

Other options include 4th and 5th axis rotary tables, automatic pallet changer, through-coolant spindle, and high speed machining capabilities.

Johnford Super Hi-Net series of vertical machining centers combines speed, rigidity and precision specifically aimed at high speed mold machining. To maximize surface finish quality of molds, the SHV Series machines feature Schneeberger roller type linear ways on all axes with large diameter pre-tensioned ballscrews. Weiss integral spindles with 31 hp are standard equipment.

X-Y-Z travels for the four-machine series range from 33″ x 24″ x 24″ (838 mm x 600 mm x 600 mm) to 48″ x 28″ x 25″ (1219 mm x 711 mm x 635 mm).

Standard features include a heavy-duty 24-tool arm-type automatic tool changer mounted to the left side of the machine for easy maintenance, a chip removal system consisting of twin screw type rear discharge conveyors, a high volume coolant system, and a full machine enclosure to contain chips and coolant.

The vertical machining center was designed to maximize ergonomic efficiency. The Y-axis servo motor location in the back of the machine allows the table to move close to the front of the machine within easy reach of the operator. The Fanuc 18iMB control features AI NANO HPCC to facilitate high speed, high accuracy machining. A twin-spindle version of the machine is available as well.

Optional accessories include 1,000 psi through-spindle coolant, minimum quantity lubrication (MQL) coolant systems, up to 120 tool capacity tool magazines, automatic pallet changers, part and tool probes, linear scales and thermal compensation software.
