For a technician working with the HMC70, the value of this document is in how it links machine-level information together. A parts drawing can be checked against the relevant assembly procedure, an inspection item can be read alongside the adjustment section, and the specification pages provide the travel, table, spindle, feed, ATC and motor data needed to understand the machine before work begins. The manual also records recommended oil types and quantities, periodic inspection intervals, hydraulic and pneumatic pressures, ATC component functions and rotary table maintenance details.

Machine Areas and Technical Scope

The general specification section lists HMC70 travel values of 2200 mm on X, 1600 mm on Y, 1600 mm on Z and 550 mm on W. The table is given as 1200 x 1500 mm with a maximum loading weight of 5000 kg. Spindle taper is ISO No. 50, spindle speed is listed as 35 to 3000 rpm and the spindle is described with a two-step automatic speed change. Rapid feed for X, Y and Z is 12000 mm/min, while 3-axis cutting feed is listed as 1 to 5000 mm/min. The ATC is shown with 60 pockets, maximum tool diameter of 125/250 mm, maximum tool length of 300 mm, maximum tool weight of 25 kg and a tool-to-tool change time of 9 seconds. Total machine weight is stated as 22500 kg.

The main components chapter explains the base, carriage, table, column, head, ATC, electric cabinet and chip conveyor, and then separates the machine into systems. The ATC section covers the arm, tool magazine, tool pocket, guard and manual magazine controls. The table section includes loading and dimension information plus notes on the HBM4 index table motor installation for frame-only arrangements. The head section describes the spindle, driving unit, encoder and tool unclamp device, and includes spindle bearing maintenance guidance and clamping force test values. The axes section lists ballscrew dimensions, positioning accuracy and repeatability. Separate sections address the spindle oil cooler, hydraulic system, pneumatic system, auto lubrication unit, coolant system, chip removal devices, electric devices and name plates.

Installation and preparation content covers environmental requirements, foundation planning, temporary leveling, mortar filling, power and air source connection, fixture removal, cleaning and oil supply. The manual gives a power capacity of 50 kVA and a cable section area of 22 mm2 for the power connection example, and it describes air source connection requirements with a pressure range of 5.5 to 7.5 kgf/cm2. These are the kinds of details a maintenance technician needs when preparing the machine area and checking services before operation.

Maintenance, Adjustment and Parts Reference

The periodic inspection chapter sets out inspection points for the arm type ATC, table, axes system, spindle head, air service unit, lubrication unit, oil cooler option, name plates, coolant and chip devices, and electric devices. The adjustment and maintenance chapter expands this into regular inspection lists, oiling charts and step-by-step maintenance instructions. It includes procedures for inspecting the lubrication system, adjusting reference points on X, Z and Y axes, adjusting gibs on X and Z axes, cleaning the chip drawer, adjusting air pressure, setting the oiler flow rate, supplying oil to the oilier, extracting water from the filter unit, cleaning filters, adjusting the pressure switch, checking the lubrication unit, servicing the coolant tank and chip pan, applying grease to the chip conveyor and cleaning the air filter option.

The parts drawing and specification chapter is organized by machine assembly. It includes head stock, W-axis, W-axis with CTS, W-axis transmission, spindle transmission, rotary table drawing A and drawing B, X-axis, Z-axis, base, Y-axis, counter balance weight, swivel type panel, floor type console, electric cabinet assembly, table guard, ATC and safety guard option. Each parts list provides item numbers, part numbers where shown, descriptions, quantities and remarks such as screw sizes, bearing numbers, motor variants and option notes. This makes the manual useful for identifying a component before ordering or replacing it, and for understanding how the assembly is put together.

The assembly procedure chapter goes further into the sequence for base, carriage, auxiliary guide way, column, ATC, chip auger, chip conveyor, sheet metal, oil cooler and hydraulic unit and coolant tank, cable carriers, wiring and piping set-up, telescopic way cover and the facing head option. The ATC assembly section includes leveling, chain fixing, arm adjustment, tool pocket alignment and trouble shooting cases. The facing head option section gives separate procedures for Fanuc and Heidenhain controller arrangements, including spindle orientation codes and transmission shaft alignment steps.

Rotary Table and Controller Information

Chapter 10 is a dedicated rotary table manual covering safety introduction, specifications, dimensions, installation and preparation, operating preparation, maintenance and trouble shooting. It describes an HC-800H-B table with a 1500 x 1200 mm turntable, 60 mm center hole, 425 mm overall height, 22 mm T-slot width, 11.1 rpm rotation speed, 1/180 total speed reduction ratio and hydraulic brake torque of 4050 kg-m. It also gives indexing accuracy of +/- 5 seconds, repeatable accuracy of 1 second and hydraulic pressure of 35 bar. Maintenance topics include worm gear backlash measurement and adjustment, clamp and unclamp confirmation adjustment, zero return system adjustment, lubricant recommendations and a maintenance schedule.

Chapter 11 covers controller operational procedure with power on, machine ready checks, axes reference, warming up, main operation panel functions, mode selection, spindle controls, feed controls, over travel release, cycle start, feed hold, feed rate override, rapid override, spindle override, alarm signal, program stop, memory protect key and options. It also includes a sub panel section for horizontal machines, an M code list, tool probe description, ATC swing arm action, magazine trouble shooting, option head setup and alarm and operation message lists. Chapter 12 contains electrical diagrams.

The Milltronics HMC70 Machining Center Operation Mechanical Drawings and Parts Manual 2011 supports practical tasks such as checking machine specifications, preparing for installation, identifying parts from assembly drawings, following periodic inspection schedules, adjusting axis reference points and gibs, servicing the lubrication and coolant systems, understanding ATC and rotary table maintenance, and referencing controller operations and alarm messages. Having the correct HMC70 procedures and part references in one PDF helps reduce guesswork when maintaining or repairing the machine and gives operators a clear reference for the machine systems they work with.
