Features

The saw is built on a structural weldment with integral fork pockets and wireways. A strategically placed baffle impinges sparks from the cut and decelerates larger particles so they drop into the easily removable debris drawer for clean out. The saw head and work holding devices are aligned on a ground top plate mounted to the base. The compact design minimizes required floor space.
The saw head is designed for cutting with a nominal 16”/400mm diameter abrasive wheel at up to 13,000sfm or 65m/sec wheel speed (Vc). The saw’s rocker arm is a heavy aluminum casting, heat treated, and is precision machined for the crucial bearing-to-trunnion shaft alignment that provides for straight, vertical cuts. The rocker arm rotates on a trunnion stand the height of which can be custom set at assembly based on the work pieces to be cut. The structural aluminum castings are T6 heat treated for stiffness and long life. It is a time-proven design that has survived field testing and has contributed to the Severit-with-Everett reputation for reliability for over 58 years.
The 3,100-rpm main wheel spindle drives the 4”/100mm cast iron wheel flange. The abrasive cutoff wheel is mounted on a 1”/25.4mm arbor shaft and clamped by the outer wheel flange. The wheel flanges are assembled on the shaft and faced and trued as an assembly for balance and straightness. Refer to ANSI B7.1, EN 12413 and FEPA for complete guidelines.
The 20HP/15 kW induction motor standard spindle speed is 3450RPM operating with dual (safety redundant) across the line starters. If the optional CutSense Sinamics VFD is purchased, wheel speed would typically be 14,200sfm/71m/s. Drive includes standard VFD features as well as ProfiSafe communications, Safe Torque Off (“STO”), Safe Stop One (“SS1”) and other safety-related functionality. Either motor control system includes a stand- alone “zero-speed” safety monitoring relay.
The saw control system provides your operator process feedback in real time to protect the operator, wheel, work, and saw from overly aggressive cutting. A LED indicator flashes colored and audible codes during the cutting cycle. Green for a moderate process (<80% of drive current use), yellow/magenta during moderately aggressive cutting (>80% but less than 100%) and red for very aggressive cutting (>100%). This feedback helps train the operator to use the power available for fast cutting cycles, but not so fast as to shorten the life of the saw and motor…or to shatter the wheel, damage the work, or damage the machine.
The saw head is fed through the cut by the same industrial-duty hydraulic cylinder (equipped with extremely abrasive environment seals) that has made Everett powerhead saws known for reliability. The hydraulic system is controlled by an appropriately sized power unit complete with pump, reservoir, pressure relief, proportional- directional valve, and associated control switches and safety valving. The power unit also controls hydraulic work clamping, if so equipped.
All the material handling surfaces will be lined with protective wear materials that will not affect the precisely ground OD of the material to be cut. Conveyor rollers will be coated in polyurethane, and walls of the conveyors will have Delrin wear plates that run the full length of the cutting system. The entire vise will also be lined with replaceable Delrin plates.
The saw system’s motors, hydraulics, operations, and programming are controlled by a failsafe PLC and associated failsafe I/O cards. If the CutSense option is purchased, the main spindle ABB/Baldor motor is controlled by a VFD with dynamic braking. Hydraulic motion is coordinated by the PLC through a proportional-directional valve as commanded by the PLC and speed-control potentiometer.
This is a production saw designed for injury-free operations in a modern manufacturing environment. The system is designed to adhere to the best functional safety practices (ISO13849) and to be EN Machinery Directive compliant. The safety systems were designed based on a detailed and comprehensive formal risk assessment to ISO12100. The vice clamps and cutting area are fully protected in the interlocked machine enclosure for safety and to contain smoke and debris. Easy access, interlocked doors allow for easy wheel change and clean up yet protect your operator from the common dangers of an open, tool room chop saw originally designed for highly skilled operators. Safety interlocks prevent automatic operation of the saw if the guarding is not secured or if the wheel is turning. Cycle start requires two-handed control, including actuation of the clamps, for operator safety.
