About this file
This document contains technical specifications and required accessories for a knee mill machine and a lathe machine for federal procurement.
Knee Mill Specifications and Requirements: The knee mill is a manual variable-speed machine with a 3 horsepower spindle, 10 x 54 inch table, and R8 spindle taper. Key specifications include variable spindle speeds of 60–4,300 rpm, 39.6 inches of longitudinal travel, 15.6 inches of cross travel, and 15 inches of knee travel. The machine weighs 2,985 pounds and requires 208/230/460 volt, 3-phase power. Required accessories include a pneumatic power drawbar compatible with R8 tooling, variable-speed X-axis and Y-axis power feeds, a Z-axis/knee power feed, a 3-axis digital readout system (equivalent to ACURITE 300 DRO), a precision 6-inch milling machine vise with approximately 9-inch maximum jaw opening, and a machine-mounted LED work light operating from 110/120 VAC power. All accessories must be completely installed and operational upon delivery.
Lathe Specifications and Requirements: The lathe features a 15 x 50 inch swing and center distance with a 7.67-inch height of center. The headstock includes a 2.12-inch spindle bore with D1-6 camlock spindle nose, 4MT spindle nose taper, and three infinitely variable spindle speed ranges (Low: 15–300 rpm, Mid: 35–830 rpm, High: 110–2,500 rpm). The 10 horsepower spindle motor and machine dimensions are 99 x 63 x 44 inches. Required accessories include a 12 kVA input transformer for 208V 3-phase operation, heavy-duty precision live center with 5MT taper, heavy-duty steady rest and follower rest with bronze tips and rollers, an Aloris CA-size quick-change tool post with minimum four tool holders, eight anti-vibration/leveling pads, 10-inch 3-jaw and 12-inch 4-jaw chucks compatible with the D1-6 spindle nose, precision tailstock drill chuck with 5MT-to-3JT arbor, and a 2-axis digital readout system with constant surface speed functionality and thread-assist capability. All systems must be completely installed, aligned, calibrated, and operational prior to delivery.
