Auto Milling
Mainland Automatic Milling Machine
An automatic milling machine for fast milling of non-ferrous and steel samples for emission and X-ray spectrometer analysis. Automatic fine surface milling guarantees the highest level of reproducibility through automatic processing of the specimen.
A milling machine removes material from a work piece by rotating a cutting tool (cutter) and moving it into the workpiece. Milling machines, either vertical or hori- zontal, are usually used to machine flat and irregularly shaped surfaces and can be used to drill, bore, and cut gears, threads, and slots.
Auto Milling Machine complete in all respects, including specially designed slides over saddle and cross slide with rolling contact, heavy-duty lead screw, 10″ dia 3-jaw self-centering chuck, milling head, auto-indexing arrangement, three roller support, multiple headstock spindle speeds, quick carriage return, 1 No. electric coolant pump & coolant tank, adjustable limit sensors, 1 No. each 1 HP & 2 HP motors for cutter spindle and headstock drive, a set of tools, etc. as per our standard design and specifications capable of milling CTC rollers of up to 13? dia. The machine is supplied with a Linear Guide for accuracy & smooth sliding and a suitable control panel for easy operation.
Salient Features of Auto Milling Machine :
Cross saddle speed movement achieved by adjustable variable frequency drive provided in the machine.Cutter engaging & disengaging will be done by synchronous motor & accurately positioned proximity sensor. An auto-indexing arrangement will control the indexing of each helical groove.The coolant system automatically provides coolant at the time of operation. LED display unit will show counting of the number of helical grooves completed.Saddle & Cross Slide movement will be on chrome-plated hardened linear guides.Zero backlashes lead screws for smooth appropriate movement for each helical groove cutting operation. Head Stock with Assey- Specially designed headstock with indexing head assembly and mechanical actuator. Steady headstock with phosphor bronze worm wheel. Digital position indicator- It indicates the displacement of the mechanism controlled by the spindle from the start position. Linear Guide-Installation to Achieve High Accuracy and Rigidity.
Benefits:
Cross slide, saddle moves on linear guide ensures quality and precision cutting operation. Main lead screw for Saddle placed at an appropriate location to avoid cutting metal chips fall & damage the lead screw nut. Auto lubrication systems ensure less wear & tear for precision components. Low power consumption & less production time provide less operation cost. Even a semi-skilled operator can efficiently use this equipment.
