About this machine
The Gildemeister CTX 420 Linear is a used CNC lathe — sometimes referred to as a turning centre — offered for sale from Hungary at $80,000. CNC lathes are precision machine tools used for turning, facing, boring, and related metal-cutting operations under computer numerical control, and Gildemeister is a well-established German manufacturer of high-precision CNC turning and milling machines serving the aerospace, automotive, medical, and general engineering industries.
This 2006 machine is equipped with a bar feeder and has logged 36,606 switching-on hours and 22,806 working hours. The main spindle accepts bar stock up to 65 mm in diameter, has a front bearing diameter of 120 mm, a through-bore of 79 mm, and accepts chuck flanges of 170 h5 mm. It is rated at 25 kW continuous (S1/100% ED), delivers up to 270 Nm of torque at that rating, and reaches a maximum speed of 5,000 rpm, with a critical speed noted at 900 rpm. The main spindle also functions as a C-axis, indexed to 0.025° accuracy, with a holding torque of 200 Nm and a maximum C-axis speed of 250 rpm.
The sub-spindle mirrors the main spindle in several respects: it is also rated at 25 kW continuous, but spins to a higher maximum of 7,000 rpm (critical speed 1,500 rpm) and delivers up to 160 Nm of torque. Its chuck flange is 140 h5 mm, front bearing diameter 90 mm, and through-bore 57 mm, accepting bar up to 42 mm. It too operates as a C-axis with 0.025° indexing accuracy, a 250 rpm C-axis speed, and a holding torque of 120 Nm.
In terms of workpiece capacity, the machine swings a maximum rotation diameter of 680 mm, with a maximum diameter over the guide of 565 mm, a maximum turning diameter of 324 mm, and a maximum turning length of 600 mm. The cross carriage provides 185 mm of X travel, 635 mm of longitudinal Z travel, and ±40 mm of vertical Y travel. Rapid traverse rates are 60 m/min in X, 15 m/min in Y, and 45 m/min in Z, with feed forces of 3.5 kN in X and 7 kN in both Y and Z. The Z-axis ball screw is 40 × 15 mm pitch; the Y-axis ball screw is 40 × 5 mm. The sub-spindle Z2 axis adds 666 mm of longitudinal travel at a rapid rate of 45 m/min with a matching 40 × 15 mm ball screw.
The turret accommodates 12 tool positions to VDI 69880 standard with a 40 mm shank diameter, using a Tool Disc SW 320 radial housing. All 12 positions are driven, with the live tooling rated at 4.9 kW and 10.5 Nm at 100% ED and a maximum speed of 4,500 rpm.
The hydraulic system has a 10-litre capacity, a 2.2 kW pump, and a maximum system pressure of 80 bar, with clamping and tailstock pressure adjustable between 10 and 60 bar. The coolant system holds 210 litres, with a 1.7 kW pump delivering 20 litres per minute at 6 bar. Electrical connection requires 50 kVA at 400 V / 50 Hz, protected at 80 A (delayed, VDE 0100), and tolerates a supply variation of +6% / −10%. The machine measures 4,890 × 2,460 × 2,080 mm (L × W × H) including the chip conveyor, and weighs approximately 6,500 kg without the chip conveyor. Workplace noise levels measured to DIN 45635 Part 1 are 77 dB(A) during machining and 78 dB(A) at idle.
