Input via monitor. The control has all the supervision and fault diagnosis features necessary for fully automatic working process. * 2 workspindle units, left and right, which can be set at any angle. * CNC controlled: Z and W Axes for tool cross slide. X and U Axes for tool longitudinal slide. * L and O Axes for milling spindle. C Axis for workspindle rotation. * Manually controlled: Tool slide rotary table (B and E Axes). Tool slide vertical infeed (V and Y Axes). Tilt of tool head (A and D Axes). All axes have digital display in the control. * Hydraulically operated workpiece clamping device in conjunction with an automatic loading device using workpiece feed / conveyor belt and swivelling loading device, as well workpiece control by air. Fpodpfet Hwylsx Adaed * Coolant equipment with chip conveyor. * Noise protection cabin. * Central lubrication. * Built-on hydraulic unit. * Pneumatically driven safety doors. * Deburring device, etc. The machine uses the hypocycloidal milling principal, with electronically synchronized tool and workpiece axes for working straight roof-formed teeth, symmetric as well as asymmetric forms. Advantages are high precision and productivity. Condition : Good to very good. Machine can soon be inspected under power. Delivery : Ex stock, as inspected Payment : Net, after conclusion of contract Thank you for your interest. We always have a good selection of gear machines available on stock.

Condition: refurbished (used), functionality: fully functional, Year of construction: 2024, broaching length: 1,000 mm, number of broaching positions: 1, broaching speed: 3 m/min, Manufacturer: Rausch (Haan/Rhld) Model: RS 6/1000 Machine No.: 51261 Year of Manufacture: 1978 Weight: 680 kg Overhauled: 11/2024 by Wiemers AG General Information / Technical Data: Overhauled mechanical vertical broaching machine Rausch RS 6 G Pulling force: 60 kN Broaching speeds: 3 m/min and 6 m/min Return speed: 6 m/min Fsdpfow Ighisx Adaspd Maximum stroke: 1000 mm Maximum tool length: 1200 mm Table dimensions / Working area: 610 x 470 mm / 520 x 320 mm Table aperture: Ø90 mm for standard broaching mandrels Workpiece diameter: unlimited Dimensions (H x W x D): 2,250 mm x 850 mm x 1,200 mm (H = table height from floor, without attachments) Motor: 4.4 kW / 5.5 kW Power supply: 400 Volt / 50 Hz Additional modifications/upgrades to the original machine performed: - External stroke adjustment - New, machine-independent, reproducible tool length adjustment system - Additional limit switches for end position monitoring - Safety door with monitoring (integrated in the emergency circuit) - Machine enclosure below safety door with chip protection and tool storage area - Electrical sensing of clamping jaws (tool removal monitoring to prevent unintended retraction of the broaching bridge) - Coolant swing system with solenoid valve operated during swing motion (for switching on coolant before broaching stroke – optical flow control ensures lubrication, no dry cutting!) - Routing of electrical cables in protective steel conduits - Heavy-duty control cabinet mounting for machine components - Additional oil-proof drip tray on the control cabinet - Three-sided closed splash guard cabin (W = 960 x D = 450 x H = 590 mm) - Reinforced chip screen with magnetic separator - Control panel made of stainless steel with durable labeling - 4 central lubrication points for trapezoidal spindle drive Remarks: The machine has been completely overhauled, the machine body fully refurbished. All wear parts have been replaced. - New trapezoidal spindles and spindle nuts made from cast wear-resistant bronze - All bearings and seals renewed - The coolant system (pump, solenoid valve, and drain tap), including the coolant/lubrication swing system, is new - The clamping jaws are new - Complete electrical system (control cabinet) is new - All sheet metal and enclosures are new - The following components have been overhauled and re-used: - Machine base - Machine column - Machine table with table insert - Broaching bridge (clamping jaws new) - Gear wheels - Electric motor (new brake, new bearings) The machine is stored in our warehouse and can be inspected under power. The attached images are original photos of the machine. The machine is CE marked. The CE marking corresponds to the status as of 1998 (first overhaul).
