Comec ACF170 Cylinder Boring Milling Machine

Key Features

• Combined Boring + Resurfacing Capability — Lets you re-bore cylinders and plane the block deck in one machine — useful for full engine rebuilds or block overhauls.
• Wide Boring Range — Supports bores from 30 mm to 170 mm (≈ 1.18″ – 6.69″), covering most car and light-truck engines.
• ood Table & Head Travel for Versatility — Head vertical travel up to 670 mm, head-to-table clearance up to 940 mm, and table surface of 1040 × 370 mm with longitudinal travel 1000 mm and transverse travel 200 mm — enough to handle a wide variety of block sizes.
• Adjustable Spindle & Feed — Variable spindle speed (75–700 rpm) and boring-bar feed rate (0–175 mm/min), giving flexibility for different bore sizes and materials.
• Motorized Table Feed (on ACF variant) — The ACF170 (as opposed to simple boring-only models) includes a motorized traverse table with adjustable feed — more efficient and precise for resurfacing operations.
• Compact Footprint & Shop-Friendly Size — Machine dimensions of approx. 1030 × 1020 × 2000 mm make it feasible for smaller shops or garages while still offering full functionality.
• Standard Tooling & Setup Devices Included — Comes with boring spindles (for various bore ranges), milling plate, tool holders, centering and depth-control devices, parallel supports, and all necessary accessory tooling to start work.
