  Workholding method by part type

The 1610 class fills a footprint of about 3.2 m by 2.4 m once you account for the table, gantry travel, control cabinet, and operator space. Leave at least 800 mm at the front for loading sheet and 500 mm at the rear for cable and dust extraction. If the machine sits against a wall, the Z axis will not reach full retract without hitting the ducting. Measure the door opening before delivery day. A machine that fits the crate but not the aisle is a common first headache.

Concrete matters more than most buyers expect. A slab rated for 150 mm thickness and 3,000 psi is the minimum for a machine of this size; 200 mm and 4,000 psi with rebar is better if you plan to cut steel or run heavy fixtures. Isolation pads under each foot reduce the vibration that shows up as chatter on the side walls of deep pockets. Do not bolt the machine to a suspended floor without an engineer's sign-off. The harmonics will find every thin rib in your part.

Power supply needs to match the spindle and servo load, not the label on the cabinet. A 1610 with an 8-9 kW spindle typically draws 32-40 A at 380-400 V three-phase. Run a dedicated circuit with a lockable disconnect within 3 m of the cabinet. Add a separate 220 V single-phase line for the control, vacuum pump, and dust collector. Undersized wiring shows up as servo faults during rapid moves, not during light cuts.

Compressed air is the fourth utility people forget. Most 1610 machines need clean, dry air at 0.6-0.8 MPa for the tool clamp, air blast, and sometimes the ATC. A 200 L receiver tank with a refrigerated dryer keeps moisture out of the spindle taper. Wet air causes tool holder sticking, which then shows up as Z height variation of 0.05 mm or more. That is enough to scrap a finishing pass.

Leveling is not about making the machine look straight. It is about removing twist from the base casting so the linear guides stay parallel over 1,600 mm of travel. Start by cleaning the floor and the foot pads. Place a precision level on the table in the X direction and shim the feet until the bubble sits inside two divisions. Repeat in Y. Then check the diagonal. If X and Y are level but the diagonal is not, the frame has a twist that will show up as a tapered cut.

A 0.02 mm per 300 mm tolerance is the practical target for a machine of this size. That works out to about 0.1 mm of error across the full X travel if you ignore it. On a mold or a long bracket, 0.1 mm is the difference between fitting and rework. Do not trust the bubble on a cheap level. Use a machinist level rated at 0.02 mm per meter, or a laser alignment system if you have one. The time spent here pays back on the first job.

Once the base is level, check squareness between X and Y. Mount a dial indicator on the spindle and sweep a known square or a granite square placed on the table. Most builders hold 0.01-0.02 mm over 300 mm. If the machine is out, the fix is usually a parameter adjustment or a mechanical alignment of the gantry, not a shim under the feet. Call the builder before you start loosening bolts. You can make a square machine worse in an afternoon.

Repeat the level check after 48 hours of running. New machines settle as the castings relax and the foundation takes load. A re-check costs 30 minutes. Skipping it costs a scrapped batch when the twist reappears under cutting load. We see this on machines that were leveled on a Friday and put into production on a Monday without a second pass.

The 1610 table is large enough that workholding strategy changes with part size. For sheet goods and flat plates, a vacuum table with zoned gaskets is the fastest option. You can set up a 1,500 × 900 mm panel in under five minutes and cut the full profile without clamps in the toolpath. The catch is that vacuum needs a flat, non-porous surface. MDF and open-cell foam pull air through the material and lose hold. Seal the edges or use a sacrificial spoilboard.

For metal plates and blocks, use a vise or a fixture plate. A 200 mm vise on a 1,600 mm table leaves plenty of room for multiple setups, but you need to indicate the vise jaw parallel to the X axis within 0.01 mm. Otherwise every part comes off the machine with a taper that looks like a machine geometry problem. It is almost always the vise. Indicate the fixed jaw, not the movable one. The movable jaw floats and will lie to you.

Toe clamps and step clamps are the fallback for one-off parts and odd shapes. They work, but they interrupt the toolpath and they can lift the part if you overtighten. Use a torque wrench and follow the clamp maker's number. For a 12 mm toe clamp, 25-30 N·m is usually enough. More than that bows the plate and you cut a concave surface. After the cut, the plate springs back and the flatness is gone.

Deep pockets and thin walls need a different approach. Support the part from below with a fixture that matches the finished geometry, or leave tabs and cut them off in a second operation. A 1.5 mm wall in aluminium will sing at 8,000 rpm if it is unsupported. Reduce radial engagement to 5-8 percent of the cutter diameter and keep the toolpath moving. Stopping in a corner is what breaks small end mills.

Tool length offsets are the most common source of Z errors on a 1610. Every tool in the magazine needs a measured length, and that number changes with holder seating, thermal growth, and wear. Use a tool presetter if you have one, or touch off on a gauge block on the table. The gauge block method is accurate to about 0.01 mm if you are careful. Bring the tool down in 0.01 mm increments until it just drags on the block. Do not spin the tool while touching off. A spinning cutter will cut the block and give you a false zero.

Work offsets for a large table are usually set with an edge finder or a probe. An edge finder with a 10 mm diameter body needs a 5 mm offset in the direction you touched. A coaxial indicator is slower but more accurate on rough stock. For production, a spindle probe pays for itself in a week. It finds the corner, sets G54, and checks the stock size in one cycle. If you run the same part family every day, save the offset in a subprogram and recall it instead of re-probing.

Warm-up is not optional on a machine with a 1,600 mm ballscrew. The screw grows as it warms, and the growth shows up as position error at the far end of travel. Run a warm-up cycle that exercises the full X, Y, and Z strokes for 10-15 minutes before the first cut. A simple program that moves to the corners at 50 percent rapid is enough. After warm-up, re-check the work offset. On a cold morning, the difference can be 0.03-0.05 mm.

Spindle warm-up is separate. Most builders publish a stepped ramp: 1,000 rpm for 2 minutes, 4,000 rpm for 3 minutes, 8,000 rpm for 5 minutes, then to your cutting speed. Skipping the ramp shortens bearing life and, on a cold day, can trip a spindle fault. If the machine has been sitting for more than a week, run the ramp twice. The grease in the bearings needs to redistribute before you put load on it.
